Additionally, [this issue](https://github.com/SynoCommunity/spksrc/issues/2758), still open as of 2018/06/24, indicates that the Debian Chroot package is not suitable for DSM versions greater than version 5 and may corrupt system libraries and render the NAS unable to boot. - -The good news is that the 64-bit static installer works fine if your NAS is one that uses the amd64 architecture. It will install the content into `/opt/netdata`, making future removal safe and simple. - -When Netdata is first installed, it will run as *root*.

For Linux instances, +we recommend either the [`kickstart.sh` automatic installation script](kickstart.md) or [.deb/.rpm +packages](packages.md). + +To see the full list of approved methods for each operating system/version we support, see our [distribution +matrix](../../DISTRIBUTIONS.md). That table will guide you to the various supported methods for your cloud instance. + +If you have issues with Netdata after installation, look to the sections below to find the issue you're experiencing, +followed by the solution for your provider. + +## Post-installation configuration + +Some cloud providers require you take additional steps to properly configure your instance or its networking to access +all of Netdata's features. + +### Add a firewall rule to access Netdata's dashboard + +If you cannot access Netdata's dashboard on your cloud instance via `http://HOST:19999`, and instead get an error page +from your browser that says, "This site can't be reached" (Chrome) or "Unable to connect" (Firefox), you may need to +configure your cloud provider's firewall. + +Cloud providers often create network-level firewalls that run separately from the instance itself. Both AWS and Google +Cloud Platform calls them Virtual Private Cloud (VPC) networks. These firewalls can apply even if you've disabled +firewalls on the instance itself. Because you can modify these firewalls only via the cloud provider's web interface, +it's easy to overlook them when trying to configure and access Netdata's dashboard. + +You can often confirm a firewall issue by querying the dashboard while connected to the instance via SSH: `curl +http://localhost:19999/api/v1/info`. If you see JSON output, Netdata is running properly. If you try the same `curl` +command from a remote system, and it fails, it's likely that a firewall is blocking your requests. + +Another option is to put Netdata behind web server, which will proxy requests through standard HTTP/HTTPS ports +(80/443), which are likely already open on your instance.

See how to [access the Netdata +dashboard](#access-the-netdata-dashboard) to confirm it's working as expected, or see the next section to [configure the +Helm chart](#configure-the-netdata-helm-chart) to suit your cluster's particular setup. + +## Configure the Netdata Helm chart + +Read up on the various configuration options in the [Helm chart +documentation](https://github.com/netdata/helmchart#configuration) to see if you need to change any of the options based +on your cluster's setup. + +To change a setting, use the `--set` or `--values` arguments with `helm install`, for the initial deployment, or `helm upgrade` to upgrade an existing deployment. + +```bash +helm install --set a.b.c=xyz netdata netdata/netdata +helm upgrade --set a.b.c=xyz netdata netdata/netdata +``` + +For example, to change the size of the persistent metrics volume on the parent node: + +```bash +helm install --set parent.database.volumesize=4Gi netdata netdata/netdata +helm upgrade --set parent.database.volumesize=4Gi netdata netdata/netdata +``` + +### Configure service discovery + +As mentioned in the introduction, Netdata has a [service discovery +plugin](https://github.com/netdata/agent-service-discovery/#service-discovery) to identify compatible pods and collect +metrics from the service they run. The Netdata Helm chart installs this service discovery plugin into your k8s cluster. + +Service discovery scans your cluster for pods exposed on certain ports and with certain image names. By default, it +looks for its supported services on the ports they most commonly listen on, and using default image names. Service +discovery currently supports [popular +applications](https://github.com/netdata/helmchart#service-discovery-and-supported-services), plus any endpoints covered +by our [generic Prometheus collector](https://learn.netdata.cloud/docs/agent/collectors/go.d.plugin/modules/prometheus). + +If you haven't changed listening ports, image names, or other defaults, service discovery should find your pods, create +the proper configurations based on the service that pod runs, and begin monitoring them immediately after deployment. + +However, if you have changed some of these defaults, you need to copy a file from the Netdata Helm chart repository, +make your edits, and pass the changed file to `helm install`/`helm upgrade`. + +First, copy the file to your administrative system. + +```bash +curl https://raw.githubusercontent.com/netdata/helmchart/master/charts/netdata/sdconfig/child.yml -o child.yml +``` + +Edit the new `child.yml` file according to your needs. See the [Helm chart +configuration](https://github.com/netdata/helmchart#configuration) and the file itself for details. + +You can then run `helm install`/`helm upgrade` with the `--set-file` argument to use your configured `child.yml` file +instead of the default, changing the path if you copied it elsewhere. + +```bash +helm install --set-file sd.child.configmap.from.value=./child.yml netdata netdata/netdata +helm upgrade --set-file sd.child.configmap.from.value=./child.yml netdata netdata/netdata +``` + +Your configured service discovery is now pushed to your cluster. + +## Access the Netdata dashboard + +Accessing the Netdata dashboard itself depends on how you set up your k8s cluster and the Netdata Helm chart. If you +installed the Helm chart with the default `service.type=ClusterIP`, you will need to forward a port to the parent pod. + +```bash +kubectl port-forward netdata-parent-0 19999:19999 +``` + +You can now access the dashboard at `http://CLUSTER:19999`, replacing `CLUSTER` with the IP address or hostname of your +k8s cluster. + +If you set up the Netdata Helm chart with `service.type=LoadBalancer`, you can find the external IP for the load +balancer with `kubectl get services`, under the `EXTERNAL-IP` column. + +```bash +kubectl get services +NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE +cockroachdb ClusterIP None <none> 26257/TCP,8080/TCP 46h +cockroachdb-public ClusterIP 10.245.148.233 <none> 26257/TCP,8080/TCP 46h +kubernetes ClusterIP 10.245.0.1 <none> 443/TCP 47h +netdata LoadBalancer 10.245.160.131 203.0.113.0 19999:32231/TCP 74m +``` + +In the above example, access the dashboard by navigating to `http://203.0.113.0:19999`. + +## Claim a Kubernetes cluster's parent pod + +You can [claim](/claim/README.md) a cluster's parent Netdata pod to see its real-time metrics alongside any other nodes +you monitor using [Netdata Cloud](https://app.netdata.cloud). + +> Netdata Cloud does not currently support claiming child nodes because the Helm chart does not allocate a persistent +> volume for them. + +Ensure persistence is enabled on the parent pod by running the following `helm upgrade` command. + +```bash +helm upgrade \ + --set parent.database.persistence=true \ + --set parent.alarms.persistence=true \ + netdata netdata/netdata +``` + +Next, find your claiming script in Netdata Cloud by clicking on your Space's dropdown, then **Manage your Space**. Click +the **Nodes** tab. Netdata Cloud shows a script similar to the following: + +```bash +sudo netdata-claim.sh -token=TOKEN -rooms=ROOM1,ROOM2 -url=https://app.netdata.cloud +``` + +You will need the values of `TOKEN` and `ROOM1,ROOM2` for the command, which sets `parent.claiming.enabled`, +`parent.claiming.token`, and `parent.claiming.rooms` to complete the parent pod claiming process. + +Run the following `helm upgrade` command after replacing `TOKEN` and `ROOM1,ROOM2` with the values found in the claiming +script from Netdata Cloud. The quotations are required. + +```bash +helm upgrade \ + --set parent.claiming.enabled=true \ + --set parent.claiming.token="TOKEN" \ + --set parent.claiming.rooms="ROOM1,ROOM2" \ + netdata netdata/netdata +``` + +The cluster terminates the old parent pod and creates a new one with the proper claiming configuration.

Unless this describes you, you almost certainly want +to follow [our guide for manually installing Netdata from a git +checkout](/packaging/installer/methods/manual.md) instead. + +## Required dependencies + +At a bare minimum, Netdata requires the following libraries and tools +to build and run successfully: + +- libuuid +- libuv version 1.0 or newer +- zlib +- GNU autoconf +- GNU automake +- GCC or Xcode (Clang is known to have issues in certain configurations, see [Using Clang](#using-clang)) +- A version of `make` compatible with GNU automake +- Git (we use git in the build system to generate version info, don't need a full install, just a working `git show` command) + +Additionally, the following build time features require additional dependencies: + +- TLS support for the web GUI: + - OpenSSL 1.0.2 or newer _or_ LibreSSL 3.0.0 or newer. +- dbengine metric storage: + - liblz4 r129 or newer + - OpenSSL 1.0 or newer (LibreSSL _amy_ work, but is largely untested). + - [libJudy](http://judy.sourceforge.net/) +- Netdata Cloud support: + - A working internet connection + - A recent version of CMake + - OpenSSL 1.0.2 or newer _or_ LibreSSL 3.0.0 or newer. + - JSON-C (may be provided by the user as shown below, or by the system) + +## Preparing the source tree + +Certain features in Netdata require custom versions of specific libraries, +which the the build system will link statically into Netdata. These +libraries and their header files must be copied into specific locations +in the source tree to be used. + +### Netdata cloud + +Netdata Cloud functionality requires custom builds of libmosquitto and +libwebsockets. + +#### libmosquitto + +Netdata maintains a custom fork of libmosquitto at +https://github.com/netdata/mosquitto with patches to allow for proper +integration with libwebsockets, which is needed for correct operation of +Netdata Cloud functionality. To prepare this library for the build system: + +1. Verify the tag that Netdata expects to be used by checking the contents + of `packaging/mosquitto.version` in your Netdata sources. +2. Obtain the sources for that version by either: + - Navigating to https://github.com/netdata/mosquitto/releases and + downloading and unpacking the source code archive for that release. + - Cloning the repository with `git` and checking out the required tag. +3. If building on a platform other than Linux, prepare the mosquitto + sources by running `cmake -D WITH_STATIC_LIBRARIES:boolean=YES .` in + the mosquitto source directory. +4. Build mosquitto by running `make -C lib` in the mosquitto source directory. +5. In the Netdata source directory, create a directory called `externaldeps/mosquitto`. +6. Copy `lib/mosquitto.h` from the mosquitto source directory to + `externaldeps/mosquitto/mosquitto.h` in the Netdata source tree. +7. Copy `lib/libmosquitto.a` from the mosquitto source directory to + `externaldeps/mosquitto/libmosquitto.a` in the Netdata source tree. If + building on a platform other than Linux, the file that needs to be + copied will instead be named `lib/libmosquitto_static.a`, but it + still needs to be copied to `externaldeps/mosquitto/libmosquitto.a`. + +#### libwebsockets + +Netdata uses the standard upstream version of libwebsockets located at +https://github.com/warmcat/libwebsockets, but requires a build with SOCKS5 +support, which is not enabled by most pre-built versions. Currently, +we do not support using a system copy of libwebsockets. To prepare this +library for the build system: + +1. Verify the tag that Netdata expects to be used by checking the contents + of `packaging/libwebsockets.version` in your Netdata sources. +2. Obtain the sources for that version by either: + - Navigating to https://github.com/warmcat/libwebsockets/releases 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 libwebsockets sources by running `cmake -D + LWS_WITH_SOCKS5:bool=ON .` in the libwebsockets source directory. +4. Build libwebsockets by running `make` in the libwebsockets source + directory. +5. In the Netdata source directory, create a directory called + `externaldeps/libwebsockets`. +6. Copy `lib/libwebsockets.a` from the libwebsockets source directory to + `externaldeps/libwebsockets/libwebsockets.a` in the Netdata source tree. +7. Copy the entire contents of `lib/include` from the libwebsockets source + directory to `externaldeps/libwebsockets/include` in the Netdata source tree. + +#### 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` fro 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. For +instructions, please consult [the README file for our kernel-collector +repository](https://github.com/netdata/kernel-collector/blob/master/README.md), +which outlines both the required dependencies, as well as multiple +options for building the code. + +[](<>) diff --git a/packaging/installer/methods/synology.md b/packaging/installer/methods/synology.md new file mode 100644 index 000000000..4a0ae3551 --- /dev/null +++ b/packaging/installer/methods/synology.md @@ -0,0 +1,52 @@ +<!-- +title: "Install Netdata on Synology" +description: "The Netdata Agent can be installed on AMD64-compatible NAS systems using the 64-bit pre-compiled static binary." +custom_edit_url: https://github.com/netdata/netdata/edit/master/packaging/installer/methods/synology.md +--> + +# Install Netdata on Synology + +The documentation previously recommended installing the Debian Chroot package from the Synology community package +sources and then running Netdata from within the chroot.
