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.
