and troubleshooting + +### Automatic updates + +By default, Netdata's installation scripts enable automatic updates for both nightly and stable release channels. + +If you would prefer to update your Netdata agent manually, you can disable automatic updates by using the `--no-updates` +option when you install or update Netdata using the [automatic one-line installation +script](#automatic-one-line-installation-script). + +```bash +wget -O /tmp/netdata-kickstart.sh https://my-netdata.io/kickstart.sh && sh /tmp/netdata-kickstart.sh --no-updates +``` + +With automatic updates disabled, you can choose exactly when and how you [update +Netdata](https://github.com/netdata/netdata/blob/master/packaging/installer/UPDATE.md). + +#### Network usage of Netdata’s automatic updater + +The auto-update functionality set up by the installation scripts requires working internet access to function +correctly. In particular, it currently requires access to GitHub (to check if a newer version of the updater script +is available or not, as well as potentially fetching build-time dependencies that are bundled as part of the install), +and Google Cloud Storage (to check for newer versions of Netdata and download the sources if there is a newer version). + +Note that the auto-update functionality will check for updates to itself independently of updates to Netdata, +and will try to use the latest version of the updater script whenever possible. This is intended to reduce the +amount of effort required by users to get updates working again in the event of a bug in the updater code. + +### Nightly vs. stable releases + +The Netdata team maintains two releases of the Netdata agent: **nightly** and **stable**. By default, Netdata's +installation scripts will give you **automatic, nightly** updates, as that is our recommended configuration. + +**Nightly**: We create nightly builds every 24 hours. They contain fully-tested code that fixes bugs or security flaws, +or introduces new features to Netdata. Every nightly release is a candidate for then becoming a stable release—when +we're ready, we simply change the release tags on GitHub. That means nightly releases are stable and proven to function +correctly in the vast majority of Netdata use cases. That's why nightly is the _best choice for most Netdata users_. + +**Stable**: We create stable releases whenever we believe the code has reached a major milestone. Most often, stable +releases correlate with the introduction of new, significant features. Stable releases might be a better choice for +those who run Netdata in _mission-critical production systems_, as updates will come more infrequently, and only after +the community helps fix any bugs that might have been introduced in previous releases. + +**Pros of using nightly releases:** + +- Get the latest features and bug fixes as soon as they're available +- Receive security-related fixes immediately +- Use stable, fully-tested code that's always improving +- Leverage the same Netdata experience our community is using + +**Pros of using stable releases:** + +- Protect yourself from the rare instance when major bugs slip through our testing and negatively affect a Netdata + installation +- Retain more control over the Netdata version you use + +### Anonymous statistics + +Starting with v1.30, Netdata collects anonymous usage information by default and sends it to a self-hosted PostHog instance within the Netdata infrastructure. Read about the information collected, and learn how to-opt, on our [anonymous statistics](https://github.com/netdata/netdata/blob/master/docs/anonymous-statistics.md) page. + +The usage statistics are _vital_ for us, as we use them to discover bugs and prioritize new features. We thank you for +_actively_ contributing to Netdata's future. + +### Troubleshooting and known issues + +We are tracking a few issues related to installation and packaging. + +#### Installs on hosts without IPv4 connectivity + +Our regular installation process requires access to a number of GitHub services that do not have IPv6 connectivity. As +such, using the kickstart install script on such hosts generally does not work, and will typically fail with an +error from cURL or wget about connection timeouts. You can check if your system is affected by this by attempting +to connect to (or ping) `https://api.github.com/`. Failing to connect indicates that you are affected by this issue. + +There are three potential workarounds for this: + +1. You can configure your system with a proper IPv6 transition mechanism, such as NAT64. GitHub’s anachronisms + affect many projects other than just Netdata, and there are unfortunately a number of other services out there + that do not provide IPv6 connectivity, so taking this route is likely to save you time in the future as well. +2. If you are using a system that we publish native packages for (see our [platform support + policy](https://github.com/netdata/netdata/blob/master/packaging/PLATFORM_SUPPORT.md) for more details), + you can manually set up our native package repositories as outlined in our [native package install + documentation](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/packages.md). Our official + package repositories do provide service over IPv6, so they work without issue on hosts without IPv4 connectivity. +3. If neither of the above options work for you, you can still install using our [offline installation + instructions](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/offline.md), though + do note that the offline install source must be prepared from a system with IPv4 connectivity. + +#### Older distributions (Ubuntu 14.04, Debian 8, CentOS 6) and OpenSSL + +If you're running an older Linux distribution or one that has reached EOL, such as Ubuntu 14.04 LTS, Debian 8, or CentOS +6, your Agent may not be able to securely connect to Netdata Cloud due to an outdated version of OpenSSL. These old +versions of OpenSSL cannot perform [hostname validation](https://wiki.openssl.org/index.php/Hostname_validation), which +helps securely encrypt SSL connections. + +If you choose to continue using the outdated version of OpenSSL, your node will still connect to Netdata Cloud, albeit +with hostname verification disabled. Without verification, your Netdata Cloud connection could be vulnerable to +man-in-the-middle attacks. + +#### CentOS 6 and CentOS 8 + +To install the Agent on certain CentOS and RHEL systems, you must enable non-default repositories, such as EPEL or +PowerTools, to gather hard dependencies. See the [CentOS 6](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/manual.md#centos--rhel-6x) and +[CentOS 8](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/manual.md#centos--rhel-8x) sections for more information. + +#### Access to file is not permitted + +If you see an error similar to `Access to file is not permitted: /usr/share/netdata/web/index.html` when you try to +visit the Agent dashboard at `http://NODE:19999`, you need to update Netdata's permissions to match those of your +system. + +Run `ls -la /usr/share/netdata/web/index.html` to find the file's permissions. You may need to change this path based on +the error you're seeing in your browser. In the below example, the file is owned by the user `root` and the group +`root`. + +```bash +ls -la /usr/share/netdata/web/index.html +-rw-r--r--. 1 root root 89377 May 5 06:30 /usr/share/netdata/web/index.html +``` + +These files need to have the same user and group used to install your netdata. Suppose you installed netdata with user +`netdata` and group `netdata`, in this scenario you will need to run the following command to fix the error: + +```bash +# chown -R netdata:netdata /usr/share/netdata/web +``` + +#### Multiple versions of OpenSSL + +We've received reports from the community about issues with running the `kickstart.sh` script on systems that have both +a distribution-installed version of OpenSSL and a manually-installed local version. The Agent's installer cannot handle +both. + +#### Clang compiler on Linux + +Our current build process has some issues when using certain configurations of the `clang` C compiler on Linux. See [the +section on `nonrepresentable section on output` +errors](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/manual.md#nonrepresentable-section-on-output-errors) for a workaround. diff --git a/packaging/installer/REINSTALL.md b/packaging/installer/REINSTALL.md new file mode 100644 index 00000000..82cea498 --- /dev/null +++ b/packaging/installer/REINSTALL.md @@ -0,0 +1,66 @@ +# Reinstall Netdata + +In certain situations, such as needing to enable a feature or troubleshoot an issue, you may need to reinstall the +Netdata Agent on your node. + +## One-line installer script (`kickstart.sh`) + +### Reinstalling with the same install type + +Run the one-line installer script with the `--reinstall` parameter to reinstall the Netdata Agent.

See our [Docker +installation instructions](https://github.com/netdata/netdata/blob/master/packaging/docker/README.md#create-a-new-netdata-agent-container) for details. + +## macOS + +If you installed Netdata on your macOS system using Homebrew, you can explicitly request an update: + +```bash +brew upgrade netdata +``` + +Homebrew downloads the latest Netdata via the +[formulae](https://github.com/Homebrew/homebrew-core/blob/master/Formula/netdata.rb), ensures all dependencies are met, +and updates Netdata via reinstallation. + +If you instead installed Netdata using our one-line installation script, you can use our [regular update +instructions](#updates-for-most-systems) to update Netdata. + +## Manual installation from Git + +If you installed [Netdata manually from Git](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/manual.md), you can run that installer again +to update your agent. First, run our automatic requirements installer, which works on many Linux distributions, to +ensure your system has the dependencies necessary for new features. + +```bash +bash <(curl -sSL https://raw.githubusercontent.com/netdata/netdata/master/packaging/installer/install-required-packages.sh) +``` + +Navigate to the directory where you first cloned the Netdata repository, pull the latest source code, and run +`netdata-install.sh` again. This process compiles Netdata with the latest source code and updates it via reinstallation. + +```bash +cd /path/to/netdata/git +git pull origin master +sudo ./netdata-installer.sh +``` + +> ⚠️ If you installed Netdata with any optional parameters, such as `--no-updates` to disable automatic updates, and +> want to retain those settings, you need to set them again during this process. + +## Control automatic updates + +Starting with Netdata v1.34.0, you can easily enable or disable automatic updates on an existing installation +using the updater script. + +For most installs on Linux, you can enable auto-updates with: + +```bash +/usr/libexec/netdata/netdata-updater.sh --enable-auto-updates +``` + +and disable them with: + +```bash +/usr/libexec/netdata/netdata-updater.sh --disable-auto-updates +``` + +For static installs, instead use: + +```bash +/opt/netdata/usr/libexec/netdata/netdata-updater.sh --enable-auto-updates +``` + +and: + +```bash +/opt/netdata/usr/libexec/netdata/netdata-updater.sh --disable-auto-updates +``` + +## Control runtime behavior of the updater script. + +Starting with v1.40.0, the `netdata-updater.sh` script supports a config file called `netdata-updater.conf`, +located in the same directory as the main `netdata.conf` file. This file uses POSIX shell script syntax to define +variables that are used by the updater. + +This configuration file can be edited [using our `edit-config` +script](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md). + +The following configuration options are currently supported: + +- `NETDATA_UPDATER_JITTER`: Sets an upper limit in seconds on the random delay in the updater script when running + as a scheduled task. This random delay helps avoid issues resulting from too many nodes trying to reconnect to + the Cloud at the same time. The default value is 3600, which corresponds to one hour. Most users should not ever + need to change this. +- `NETDATA_NO_SYSTEMD_JOURNAL`: If set to a value other than 0, skip attempting to install the + `netdata-plugin-systemd-journal` package on supported systems on update. This optional package will be installed + by default on supported systems by the updater if this option is not set. Only affects systems using native packages. diff --git a/packaging/installer/dependencies/alpine.sh b/packaging/installer/dependencies/alpine.sh new file mode 100755 index 00000000..ee0504b3 --- /dev/null +++ b/packaging/installer/dependencies/alpine.sh @@ -0,0 +1,114 @@ +#!/bin/sh +# Package tree used for installing netdata on distribution: +# << Alpine: [3.12] [3.13] [3.14] [3.15] [edge] >> + +set -e + +NON_INTERACTIVE=0 +DONT_WAIT=0 + +package_tree=" + alpine-sdk + git + gcc + g++ + automake + autoconf + cmake + make + libatomic + libtool + pkgconfig + tar + curl + gzip + libuv-dev + lz4-dev + openssl-dev + elfutils-dev + python3 + zlib-dev + util-linux-dev + libmnl-dev + json-c-dev + musl-fts-dev + bison + flex + yaml-dev + " + +usage() { + cat << EOF +OPTIONS: +[--dont-wait] [--non-interactive] [ ] +EOF +} + +check_flags() { + while [ -n "${1}" ]; do + case "${1}" in + dont-wait | --dont-wait | -n) + DONT_WAIT=1 + ;; + + non-interactive | --non-interactive | -y) + NON_INTERACTIVE=1 + ;; + + help | -h | --help) + usage + exit 1 + ;; + *) + echo >&2 "ERROR: Cannot understand option '${1}'" + echo >&2 + usage + exit 1 + ;; + esac + shift + done + + if [ "${DONT_WAIT}" -eq 0 ] && [ "${NON_INTERACTIVE}" -eq 0 ]; then + printf "Press ENTER to run it > " + read -r || exit 1 + fi +} + +# shellcheck disable=2068 +check_flags ${@} + +packages_to_install= + +handle_old_alpine() { + version="$(grep VERSION_ID /etc/os-release | cut -f 2 -d '=')" + major="$(echo "${version}" | cut -f 1 -d '.')" + minor="$(echo "${version}" | cut -f 2 -d '.')" + + if [ "${major}" -le 3 ] && [ "${minor}" -le 16 ]; then + package_tree="$(echo "${package_tree}" | sed 's/musl-fts-dev/fts-dev/')" + fi +} + +for package in $package_tree; do + if apk -e info "$package" > /dev/null 2>&1 ; then + echo "Package '${package}' is installed" + else + echo "Package '${package}' is NOT installed" + packages_to_install="$packages_to_install $package" + fi +done + +if [ -z "${packages_to_install}" ]; then + echo "All required packages are already installed.

You can use it on bare metal, VMs, containers, and everything +in-between. + +But what if you're trying to bootstrap an infrastructure monitoring solution as quickly as possible? What if you need to +deploy Netdata across an entire infrastructure with many nodes? What if you want to make this deployment reliable, +repeatable, and idempotent? What if you want to write and deploy your infrastructure or cloud monitoring system like +code? + +Enter [Ansible](https://ansible.com), a popular system provisioning, configuration management, and infrastructure as +code (IaC) tool. Ansible uses **playbooks** to glue many standardized operations together with a simple syntax, then run +those operations over standard and secure SSH connections. There's no agent to install on the remote system, so all you +have to worry about is your application and your monitoring software. + +Ansible has some competition from the likes of [Puppet](https://puppet.com/) or [Chef](https://www.chef.io/), but the +most valuable feature about Ansible is **idempotent**. From the [Ansible +glossary](https://docs.ansible.com/ansible/latest/reference_appendices/glossary.html) + +> An operation is idempotent if the result of performing it once is exactly the same as the result of performing it +> repeatedly without any intervening actions. + +Idempotency means you can run an Ansible playbook against your nodes any number of times without affecting how they +operate. When you deploy Netdata with Ansible, you're also deploying _monitoring as code_. + +In this guide, we'll walk through the process of using an [Ansible +playbook](https://github.com/netdata/community/tree/main/configuration-management/ansible-quickstart/) to automatically +deploy the Netdata Agent to any number of distributed nodes, manage the configuration of each node, and connect them to +your Netdata Cloud account. You'll go from some unmonitored nodes to a infrastructure monitoring solution in a matter of +minutes. + +## Prerequisites + +- A Netdata Cloud account. [Sign in and create one](https://app.netdata.cloud) if you don't have one already. +- An administration system with [Ansible](https://www.ansible.com/) installed. +- One or more nodes that your administration system can access via [SSH public + keys](https://git-scm.com/book/en/v2/Git-on-the-Server-Generating-Your-SSH-Public-Key) (preferably password-less). + +## Download and configure the playbook + +First, download the +[playbook](https://github.com/netdata/community/tree/main/configuration-management/ansible-quickstart/), move it to the +current directory, and remove the rest of the cloned repository, as it's not required for using the Ansible playbook. + +```bash +git clone https://github.com/netdata/community.git +mv community/configuration-management/ansible-quickstart . +rm -rf community +``` + +Or if you don't want to clone the entire repository, use the [gitzip browser extension](https://gitzip.org/) to get the netdata-agent-deployment directory as a zip file. + +Next, `cd` into the Ansible directory. + +```bash +cd ansible-quickstart +``` + +### Edit the `hosts` file + +The `hosts` file contains a list of IP addresses or hostnames that Ansible will try to run the playbook against. The +`hosts` file that comes with the repository contains two example IP addresses, which you should replace according to the +IP address/hostname of your nodes. + +```conf +203.0.113.0 hostname=node-01 +203.0.113.1 hostname=node-02 +``` + +You can also set the `hostname` variable, which appears both on the local Agent dashboard and Netdata Cloud, or you can +omit the `hostname=` string entirely to use the system's default hostname. + +#### Set the login user (optional) + +If you SSH into your nodes as a user other than `root`, you need to configure `hosts` according to those user names. Use +the `ansible_user` variable to set the login user. For example: + +```conf +203.0.113.0 hostname=ansible-01 ansible_user=example +``` + +#### Set your SSH key (optional) + +If you use an SSH key other than `~/.ssh/id_rsa` for logging into your nodes, you can set that on a per-node basis in +the `hosts` file with the `ansible_ssh_private_key_file` variable. For example, to log into a Lightsail instance using +two different SSH keys supplied by AWS. + +```conf +203.0.113.0 hostname=ansible-01 ansible_ssh_private_key_file=~/.ssh/LightsailDefaultKey-us-west-2.pem +203.0.113.1 hostname=ansible-02 ansible_ssh_private_key_file=~/.ssh/LightsailDefaultKey-us-east-1.pem +``` + +### Edit the `vars/main.yml` file + +In order to connect your node(s) to your Space in Netdata Cloud, and see all their metrics in real-time in [composite +charts](https://github.com/netdata/netdata/blob/master/docs/visualize/overview-infrastructure.md) or perform [Metric +Correlations](https://github.com/netdata/netdata/blob/master/docs/cloud/insights/metric-correlations.md), you need to set the `claim_token` +and `claim_room` variables. + +To find your `claim_token` and `claim_room`, go to Netdata Cloud, then click on your Space's name in the top navigation, +then click on **Manage your Space**. Click on the **Nodes** tab in the panel that appears, which displays a script with +`token` and `room` strings. + + + +Copy those strings into the `claim_token` and `claim_rooms` variables. + +```yml +claim_token: XXXXX +claim_rooms: XXXXX +``` + +Change the `dbengine_multihost_disk_space` if you want to change the metrics retention policy by allocating more or less +disk space for storing metrics. The default is 2048 Mib, or 2 GiB. + +Because we're connecting this node to Netdata Cloud, and will view its dashboards there instead of via the IP address or +hostname of the node, the playbook disables that local dashboard by setting `web_mode` to `none`. This gives a small +security boost by not allowing any unwanted access to the local dashboard. + +You can read more about this decision, or other ways you might lock down the local dashboard, in our [node security +doc](https://github.com/netdata/netdata/blob/master/docs/netdata-security.md). + +> Curious about why Netdata's dashboard is open by default? Read our [blog +> post](https://www.netdata.cloud/blog/netdata-agent-dashboard/) on that zero-configuration design decision. + +## Run the playbook + +Time to run the playbook from your administration system: + +```bash +ansible-playbook -i hosts tasks/main.yml +``` + +Ansible first connects to your node(s) via SSH, then [collects +facts](https://docs.ansible.com/ansible/latest/user_guide/playbooks_vars_facts.html#ansible-facts) about the system. +This playbook doesn't use these facts, but you could expand it to provision specific types of systems based on the +makeup of your infrastructure. + +Next, Ansible makes changes to each node according to the `tasks` defined in the playbook, and +[returns](https://docs.ansible.com/ansible/latest/reference_appendices/common_return_values.html#changed) whether each +task results in a changed, failure, or was skipped entirely. + +The task to install Netdata will take a few minutes per node, so be patient! Once the playbook reaches the connect to Cloud +task, your nodes start populating your Space in Netdata Cloud. diff --git a/packaging/installer/methods/aws.md b/packaging/installer/methods/aws.md new file mode 100644 index 00000000..c0b92a03 --- /dev/null +++ b/packaging/installer/methods/aws.md @@ -0,0 +1,67 @@ +<!-- +title: "Install Netdata on AWS" +description: "The Netdata Agent runs on all popular cloud providers, but often requires additional steps and configuration for full functionality." +custom_edit_url: https://github.com/netdata/netdata/edit/master/packaging/installer/methods/aws.md +sidebar_label: "AWS" +learn_status: "Published" +learn_rel_path: "Installation/Install on specific environments" +--> + +# Install Netdata on AWS + +Netdata is fully compatible with Amazon Web Services (AWS). +You can install Netdata on cloud instances to monitor the apps/services running there, or use +multiple instances in a [parent-child streaming](https://github.com/netdata/netdata/blob/master/streaming/README.md) configuration. + +## Recommended installation method + +The best installation method depends on the instance's operating system, distribution, and version.

Using the standard tooling for mirroring the type of repository you want a local mirror of, such as Aptly for + APT repositories, or reposync for RPM repositories. For this approach, please consult the documentation for + the specific tool you are using for info on how to mirror the repositories. +2. Using a regular website mirroring tool, such as GNU wget’s `--mirror` option. For this approach, simply point + your mirroring tool at `https://repo.netdata.cloud/repos/`, and everything should just work. + +We do not provide official support for mirroring our repositories, +but we do have some tips for anyone looking to do so: + +- Our `robots.txt` file explicitly disallows indexing, so if you’re using a regular website mirroring tool, + you wil need to tell it to ignore `robots.txt` (for example, if using GNU wget, add `-e robots=off` to the + options you pass) to ensure that it actually retrieves everything. +- Excluding special cases of caching proxies (such as apt-cacher-ng), our repository configuration packages _DO NOT_ + work with custom local mirrors. Thus, you will need to manually configure your systems to use your local mirror. +- Packages are published as they are built, with 64-bit x86 packages being built first, followed by 32-bit x86, + and then non-x86 packages in alphabetical order of the CPU architecture. Because of the number of different + packages being built, this means that packages for a given nightly build or stable release are typically published + over the course of a few hours, usually starting about 15-20 minutes after the build or release is started. +- Repository metadata is updated every hour on the hour, and the process may take anywhere from a few seconds to + more than 20 minutes. Because of this, it makes little sense to sync your mirror more frequently than once an hour, + and it’s generally preferred to start syncing at least 30 minutes into the hour. +- A full mirror of all of our repositories currently requires up to 100 GB of storage space, though the exact + amount of space needed fluctuates over time. Because of this, users seeking to mirror our repositories are + encouraged to mirror only those repositories they actually need instead of mirroring everything. +- If syncing daily (or less frequently), some time between 05:00 and 08:00 UTC each day is usually the saftest + time to do so, as publishing nightly packages will almost always be done by this point, and publishing of stable + releases typically happens after that time window. +- If you intend to use our existing GPG signatures on the repository metadata and packages, you probably also want + a local copy of our public GPG key, which can be fetched from `https://repo.netdata.cloud/netdatabot.gpg.key`. + +## Public mirrors of the official Netdata repositories + +There are no official public mirrors of our repositories. + +If you wish to provide a public mirror of our official repositories, you are free to do so, but we kindly ask that +you make it clear to your users that your mirror is not an official mirror of our repositories. diff --git a/packaging/installer/methods/pfsense.md b/packaging/installer/methods/pfsense.md new file mode 100644 index 00000000..965fba8d --- /dev/null +++ b/packaging/installer/methods/pfsense.md @@ -0,0 +1,87 @@ +<!-- +title: "Install Netdata on pfSense" +description: "Install Netdata on pfSense to monitor the health and performance of firewalls with thousands of real-time, per-second metrics." +custom_edit_url: https://github.com/netdata/netdata/edit/master/packaging/installer/methods/pfsense.md +sidebar_label: "pfSense" +learn_status: "Published" +learn_rel_path: "Installation/Install on specific environments" +--> + +# Install Netdata on pfSense CE + +> 💡 This document is maintained by Netdata's community, and may not be completely up-to-date.

These +libraries and their header files must be copied into specific locations +in the source tree to be used. + +Before you begin, make sure that your repo and the repo's submodules are clean from any previous builds and up to date. +Otherwise, [perform a cleanup](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/manual.md#perform-a-cleanup-in-your-netdata-repo) + +### Netdata cloud + +#### JSON-C + +Netdata requires the use of JSON-C for JSON parsing when using Netdata +Cloud. Netdata is able to use a system-provided copy of JSON-C, but +some systems may not provide it. If your system does not provide JSON-C, +you can do the following to prepare a copy for the build system: + +1. Verify the tag that Netdata expects to be used by checking the contents + of `packaging/jsonc.version` in your Netdata sources. +2. Obtain the sources for that version by either: + - Navigating to https://github.com/json-c/json-c and downloading + and unpacking the source code archive for that release. + - Cloning the repository with `git` and checking out the required tag. +3. Prepare the JSON-C sources by running `cmake -DBUILD_SHARED_LIBS=OFF .` + in the JSON-C source directory. +4. Build JSON-C by running `make` in the JSON-C source directory. +5. In the Netdata source directory, create a directory called + `externaldeps/jsonc`. +6. Copy `libjson-c.a` from the JSON-C source directory to + `externaldeps/jsonc/libjson-c.a` in the Netdata source tree. +7. Copy all of the header files (`*.h`) from the JSON-C source directory + to `externaldeps/jsonc/json-c` in the Netdata source tree. + +## Building Netdata + +Once the source tree has been prepared, Netdata is ready to be configured +and built. Netdata currently uses GNU autotools as it's primary build +system. To build Netdata this way: + +1. Run `autoreconf -ivf` in the Netdata source tree. +2. Run `./configure` in the Netdata source tree. +3. Run `make` in the Netdata source tree. + +### Configure options + +Netdata provides a number of build time configure options. This section +lists some of the ones you are most likely to need: + +- `--prefix`: Specify the prefix under which Netdata will be installed. +- `--with-webdir`: Specify a path relative to the prefix in which to + install the web UI files. +- `--disable-cloud`: Disables all Netdata Cloud functionality for + this build. + +### Using Clang + +Netdata is primarily developed using GCC, but in most cases we also +build just fine using Clang. Under some build configurations of Clang +itself, you may see build failures with the linker reporting errors +about `nonrepresentable section on output`. We currently do not have a +conclusive fix for this issue (the obvious fix leads to other issues which +we haven't been able to fix yet), and unfortunately the only workaround +is to use a different build of Clang or to use GCC. + +### Linking errors relating to OpenSSL + +Netdata's build system currently does not reliably support building +on systems which have multiple ABI incompatible versions of OpenSSL +installed. In such situations, you may encounter linking errors due to +Netdata trying to build against headers for one version but link to a +different version. + +## Additional components + +A full featured install of Netdata requires some additional components +which must be built and installed separately from the main Netdata +agent. All of these should be handled _after_ installing Netdata itself. + +### React dashboard + +The above build steps include a deprecated web UI for Netdata that lacks +support for Netdata Cloud. To get a fully featured dashboard, you must +install our new React dashboard. + +#### Installing the pre-built React dashboard + +We provide pre-built archives of the React dashboard for each release +(these are also used during our normal install process). To use one +of these: + +1. Verify the release version that Netdata expects to be used by checking + the contents of `packaging/dashboard.version` in your Netdata sources. +2. Go to https://github.com/netdata/dashboard/releases and download the + `dashboard.tar.gz` file for the required release. +3. Unpack the downloaded archive to a temporary directory. +4. Copy the contents of the `build` directory from the extracted + archive to `/usr/share/netdata/web` or the equivalent location for + your build of Netdata. This _will_ overwrite some files in the target + location. + +#### Building the React dashboard locally + +Alternatively, you may wish to build the React dashboard locally. Doing +so requires a recent version of Node.JS with a working install of +NPM. Once you have the required tools, do the following: + +1. Verify the release version that Netdata expects to be used by checking + the contents of `packaging/dashboard.version` in your Netdata sources. +2. Obtain the sources for that version by either: + - Navigating to https://github.com/netdata/dashboard and downloading + and unpacking the source code archive for that release. + - Cloning the repository with `git` and checking out the required tag. +3. Run `npm install` in the dashboard source tree. +4. Run `npm run build` in the dashboard source tree. +5. Copy the contents of the `build` directory just like step 4 of + installing the pre-built React dashboard. + +### Go collectors + +A number of the collectors for Netdata are written in Go instead of C, +and are developed in a separate repository from the mian Netdata code. +An installation without these collectors is still usable, but will be +unable to collect metrics for a number of network services the system +may be providing. You can either install a pre-built copy of these +collectors, or build them locally. + +#### Installing the pre-built Go collectors + +We provide pre-built binaries of the Go collectors for all the platforms +we officially support. To use one of these: + +1. Verify the release version that Netdata expects to be used by checking + the contents of `packaging/go.d.version` in your Netdata sources. +2. Go to https://github.com/netdata/go.d.plugin/releases, select the + required release, and download the `go.d.plugin-*.tar.gz` file + for your system type and CPu architecture and the `config.tar.gz` + configuration file archive. +3. Extract the `go.d.plugin-*.tar.gz` archive into a temporary + location, and then copy the single file in the archive to + `/usr/libexec/netdata/plugins.d` or the equivalent location for your + build of Netdata and rename it to `go.d.plugin`. +4. Extract the `config.tar.gz` archive to a temporarylocation and then + copy the contents of the archive to `/etc/netdata` or the equivalent + location for your build of Netdata. + +#### Building the Go collectors locally + +Alternatively, you may wish to build the Go collectors locally +yourself. Doing so requires a working installation of Golang 1.13 or +newer. Once you have the required tools, do the following: + +1. Verify the release version that Netdata expects to be used by checking + the contents of `packaging/go.d.version` in your Netdata sources. +2. Obtain the sources for that version by either: + - Navigating to https://github.com/netdata/go.d.plugin and downloading + and unpacking the source code archive for that release. + - Cloning the repository with `git` and checking out the required tag. +3. Run `make` in the go.d.plugin source tree. +4. Copy `bin/godplugin` to `/usr/libexec/netdata/plugins.d` or th + equivalent location for your build of Netdata and rename it to + `go.d.plugin`. +5. Copy the contents of the `config` directory to `/etc/netdata` or the + equivalent location for your build of Netdata. + +### eBPF collector + +On Linux systems, Netdata has support for using the kernel's eBPF +interface to monitor performance-related VFS, network, and process events, +allowing for insights into process lifetimes and file access +patterns. Using this functionality requires additional code managed in +a separate repository from the core Netdata agent. You can either install +a pre-built copy of the required code, or build it locally. + +#### Installing the pre-built eBPF code + +We provide pre-built copies of the eBPF code for 64-bit x86 systems +using glibc or musl. To use one of these: + +1. Verify the release version that Netdata expects to be used by checking + the contents of `packaging/ebpf.version` in your Netdata sources. +2. Go to https://github.com/netdata/kernel-collector/releases, select the + required release, and download the `netdata-kernel-collector-*.tar.xz` + file for the libc variant your system uses (either rmusl or glibc). +3. Extract the contents of the archive to a temporary location, and then + copy all of the `.o` and `.so.*` files and the contents of the `library/` + directory to `/usr/libexec/netdata/plugins.d` or the equivalent location + for your build of Netdata. + +#### Building the eBPF code locally + +Alternatively, you may wish to build the eBPF code locally yourself.
