Step 12: Open cpu.conf file and Change this line into the cpu.conf file by using the below command.
root@linuxhelp:/etc/netdata/health.d# vim cpu.conf
warn: $this > (($status >= $WARNING) ? (10) : (20))
crit: $this > (($status == $CRITICAL) ? (20) : (30))
Step 13: Now restart the health service file of Netdata to apply the changes by using the below command.
root@linuxhelp:/etc/netdata/health.d# netdatacli reload-health

Step 16: Provide all these steps in vim.conf file
alarm: ram_usage
on: system.ram
lookup: average -1m percentage of used
units: %
every: 1m
warn: $this > 40
crit: $this > 60
