The ACLK establishes an outgoing secure WebSocket (WSS) connection to Netdata Cloud on port -`443`. The ACLK is encrypted, safe, and _is only established if you connect your node_. - -The Cloud App lives at app.netdata.cloud which currently resolves to the following list of IPs: - -- 54.198.178.11 -- 44.207.131.212 -- 44.196.50.41 - -> ### Caution -> ->This list of IPs can change without notice, we strongly advise you to whitelist following domains `app.netdata.cloud`, `mqtt.netdata.cloud`, if this is not an option in your case always verify the current domain resolution (e.g via the `host` command). - -For a guide to connecting a node using the ACLK, plus additional troubleshooting and reference information, read our [connect to Cloud -documentation](https://github.com/netdata/netdata/blob/master/claim/README.md). - -## Data privacy - -[Data privacy](https://netdata.cloud/privacy/) is very important to us. We firmly believe that your data belongs to -you. This is why **we don't store any metric data in Netdata Cloud**. - -All the data that you see in the web browser when using Netdata Cloud, is actually streamed directly from the Netdata Agent to the Netdata Cloud dashboard. The data passes through our systems, but it isn't stored. - -However, to be able to offer the stunning visualizations and advanced functionality of Netdata Cloud, it does store a limited number of _metadata_. Read more about our [security and privacy design](https://github.com/netdata/netdata/blob/master/docs/netdata-security.md). - -## Enable and configure the ACLK - -The ACLK is enabled by default, with its settings automatically configured and stored in the Agent's memory. No file is -created at `/var/lib/netdata/cloud.d/cloud.conf` until you either connect a node or create it yourself. The default -configuration uses two settings: - -```conf -[global] - enabled = yes - cloud base url = https://app.netdata.cloud -``` - -If your Agent needs to use a proxy to access the internet, you must [set up a proxy for -connecting to cloud](https://github.com/netdata/netdata/blob/master/claim/README.md#connect-through-a-proxy). - -You can configure following keys in the `netdata.conf` section `[cloud]`: -``` -[cloud] - statistics = yes - query thread count = 2 -``` - -- `statistics` enables/disables ACLK related statistics and their charts. You can disable this to save some space in the database and slightly reduce memory usage of Netdata Agent. -- `query thread count` specifies the number of threads to process cloud queries. Increasing this setting is useful for nodes with many children (streaming), which can expect to handle more queries (and/or more complicated queries). - -## Disable the ACLK - -You have two options if you prefer to disable the ACLK and not use Netdata Cloud. - -### Disable at installation - -You can pass the `--disable-cloud` parameter to the Agent installation when using a kickstart script -([kickstart.sh](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/kickstart.md), or a [manual installation from -Git](https://github.com/netdata/netdata/blob/master/packaging/installer/methods/manual.md). - -When you pass this parameter, the installer does not download or compile any extra libraries. Once running, the Agent -kills the thread responsible for the ACLK and connecting behavior, and behaves as though the ACLK, and thus Netdata Cloud, -does not exist. - -### Disable at runtime - -You can change a runtime setting in your `cloud.conf` file to disable the ACLK. This setting only stops the Agent from -attempting any connection via the ACLK, but does not prevent the installer from downloading and compiling the ACLK's -dependencies. - -The file typically exists at `/var/lib/netdata/cloud.d/cloud.conf`, but can change if you set a prefix during -installation. To disable the ACLK, open that file and change the `enabled` setting to `no`: - -```conf -[global] - enabled = no -``` - -If the file at `/var/lib/netdata/cloud.d/cloud.conf` doesn't exist, you need to create it. - -Copy and paste the first two lines from below, which will change your prompt to `cat`. - -```bash -cd /var/lib/netdata/cloud.d -cat > cloud.conf << EOF -``` - -Copy and paste in lines 3-6, and after the final `EOF`, hit **Enter**. The final line must contain only `EOF`. Hit **Enter** again to return to your normal prompt with the newly-created file. - -To get your normal prompt back, the final line -must contain only `EOF`. - -```bash -[global] - enabled = no - cloud base url = https://app.netdata.cloud -EOF -``` - -You also need to change the file's permissions. Use `grep "run as user" /etc/netdata/netdata.conf` to figure out which -user your Agent runs as (typically `netdata`), and replace `netdata:netdata` as shown below if necessary: - -```bash -sudo chmod 0770 cloud.conf -sudo chown netdata:netdata cloud.conf -``` - -Restart your Agent to disable the ACLK. - -### Re-enable the ACLK - -If you first disable the ACLK and any Cloud functionality and then decide you would like to use Cloud, you must either -[reinstall Netdata](https://github.com/netdata/netdata/blob/master/packaging/installer/REINSTALL.md) with Cloud enabled or change the runtime setting in your -`cloud.conf` file. - -If you passed `--disable-cloud` to `netdata-installer.sh` during installation, you must -[reinstall](https://github.com/netdata/netdata/blob/master/packaging/installer/REINSTALL.md) your Agent. Use the same method as before, but pass `--require-cloud` to -the installer. When installation finishes you can [connect your node](https://github.com/netdata/netdata/blob/master/claim/README.md#how-to-connect-a-node). - -If you changed the runtime setting in your `var/lib/netdata/cloud.d/cloud.conf` file, edit the file again and change -`enabled` to `yes`: - -```conf -[global] - enabled = yes -``` - -Restart your Agent and [connect your node](https://github.com/netdata/netdata/blob/master/claim/README.md#how-to-connect-a-node). - - |
