You can use this page as a quick reference for installing Netdata, connecting a node to the Cloud, properly editing the configuration, accessing Netdata's API, and more! + +### Install Netdata + +```bash +wget -O /tmp/netdata-kickstart.sh https://my-netdata.io/kickstart.sh && sh /tmp/netdata-kickstart.sh + +# Or, if you have cURL but not wget (such as on macOS): +curl https://my-netdata.io/kickstart.sh > /tmp/netdata-kickstart.sh && sh /tmp/netdata-kickstart.sh +``` + +#### Connect a node to Netdata Cloud + +To do so, sign in to Netdata Cloud, on your Space under the Nodes tab, click `Add Nodes` and paste the provided command into your node’s terminal and run it. +You can also copy the Claim token and pass it to the installation script with `--claim-token` and re-run it. + +### Configuration + +**Netdata's config directory** is `/etc/netdata/` but in some operating systems it might be `/opt/netdata/etc/netdata/`. +Look for the `# config directory =` line over at `http://NODE_IP:19999/netdata.conf` to find your config directory. + +From within that directory you can run `sudo ./edit-config netdata.conf` **to edit Netdata's configuration.** +You can edit other config files too, by specifying their filename after `./edit-config`. +You are expected to use this method in all following configuration changes. + +<!-- #### Edit Netdata's other config files (examples): + +- `$ sudo ./edit-config apps_groups.conf` +- `$ sudo ./edit-config ebpf.conf` +- `$ sudo ./edit-config health.d/load.conf` +- `$ sudo ./edit-config go.d/prometheus.conf` + +#### View the running Netdata configuration: `http://NODE:19999/netdata.conf` + +> Replace `NODE` with the IP address or hostname of your node. Often `localhost`. + +## Metrics collection & retention + +You can tweak your settings in the netdata.conf file. +📄 [Find your netdata.conf file](https://github.com/netdata/netdata/blob/master/daemon/config/README.md) + +Open a new terminal and navigate to the netdata.conf file. Use the edit-config script to make changes: `sudo ./edit-config netdata.conf` + +The most popular settings to change are: + +#### Increase metrics retention (4GiB) + +``` +sudo ./edit-config netdata.conf +``` + +``` +[global] + dbengine multihost disk space = 4096 +``` + +#### Reduce the collection frequency (every 5 seconds) + +``` +sudo ./edit-config netdata.conf +``` + +``` +[global] + update every = 5 +``` --> + +--- + +#### Enable/disable plugins (groups of collectors) + +```bash +sudo ./edit-config netdata.conf +``` + +```conf +[plugins] + go.d = yes # enabled + node.d = no # disabled +``` + +#### Enable/disable specific collectors + +```bash +sudo ./edit-config go.d.conf # edit a plugin's config +``` + +```yaml +modules: + activemq: no # disabled + cockroachdb: yes # enabled +``` + +#### Edit a collector's config + +```bash +sudo ./edit-config go.d/mysql.conf +``` + +### Alerts & notifications + +<!-- #### Add a new alert + +``` +sudo touch health.d/example-alert.conf +sudo ./edit-config health.d/example-alert.conf +``` --> +After any change, reload the Netdata health configuration: + +```bash +netdatacli reload-health +#or if that command doesn't work on your installation, use: +killall -USR2 netdata +``` + +#### Configure a specific alert + +```bash +sudo ./edit-config health.d/example-alert.conf +``` + +#### Silence a specific alert + +```bash +sudo ./edit-config health.d/example-alert.conf +``` + +``` + to: silent +``` + +<!-- #### Disable alerts and notifications + +```conf +[health] + enabled = no +``` --> + +--- + +### Manage the daemon + +| Intent | Action | +|:----------------------------|------------------------------------------------------------:| +| Start Netdata | `$ sudo service netdata start` | +| Stop Netdata | `$ sudo service netdata stop` | +| Restart Netdata | `$ sudo service netdata restart` | +| Reload health configuration | `$ sudo netdatacli reload-health` `$ killall -USR2 netdata` | +| View error logs | `less /var/log/netdata/error.log` | +| View collectors logs | `less /var/log/netdata/collector.log` | + +#### Change the port Netdata listens to (example, set it to port 39999) + +```conf +[web] +default port = 39999 +``` + +### See metrics and dashboards + +#### Netdata Cloud: `https://app.netdata.cloud` + +#### Local dashboard: `https://NODE:19999` + +> Replace `NODE` with the IP address or hostname of your node.
