[Health +configuration](#reload-health-configuration) files are the only exception, as they can be reloaded without restarting +the entire Agent. + +Stopping or restarting the Netdata Agent will cause gaps in stored metrics until the `netdata` process initiates +collectors and the database engine. + +## Using `systemctl`, `service`, or `init.d` + +This is the recommended way to start, stop, or restart the Netdata daemon. + +- To **start** Netdata, run `sudo systemctl start netdata`. +- To **stop** Netdata, run `sudo systemctl stop netdata`. +- To **restart** Netdata, run `sudo systemctl restart netdata`. + +If the above commands fail, or you know that you're using a non-systemd system, try using the `service` command: + +- **service**: `sudo service netdata start`, `sudo service netdata stop`, `sudo service netdata restart` + +## Using `netdata` + +Use the `netdata` command, typically located at `/usr/sbin/netdata`, to start the Netdata daemon. + +```bash +sudo netdata +``` + +If you start the daemon this way, close it with `sudo killall netdata`. + +## Using `netdatacli` + +The Netdata Agent also comes with a [CLI tool](/cli/README.md) capable of performing shutdowns. Start the Agent back up +using your preferred method listed above. + +```bash +sudo netdatacli shutdown-agent +``` + +## Reload health configuration + +You do not need to restart the Netdata Agent between changes to health configuration files, such as specific health +entities. Instead, use [`netdatacli`](#using-netdatacli) and the `reload-health` option to prevent gaps in metrics +collection. + +```bash +sudo netdatacli reload-health +``` + +If `netdatacli` doesn't work on your system, send a `SIGUSR2` signal to the daemon, which reloads health configuration +without restarting the entire process. + +```bash +killall -USR2 netdata +``` + +## Force stop stalled or unresponsive `netdata` processes + +In rare cases, the Netdata Agent may stall or not properly close sockets, preventing a new process from starting. In +these cases, try the following three commands: + +```bash +sudo systemctl stop netdata +sudo killall netdata +ps aux| grep netdata +``` + +The output of `ps aux` should show no `netdata` or associated processes running.
