drwxr-xr-x.   5 root root       141 Jul  7 03:11 netdata

Step 5: move into the Netdata directory by using the below command.

[root@linuxhelp etc]# cd netdata/

Step 6: List the files by using the below command.

[root@linuxhelp netdata]# ls -la
total 36
drwxr-xr-x.   5 root root     141 Jul  7 03:11 .
drwxr-xr-x. 137 root root    8192 Jul  7 03:01 ..

[root@linuxhelp netdata]# cd health.d

[root@linuxhelp health.d]# ll
total 0

[root@linuxhelp netdata]# ./edit-config health.d/cpu.conf
Copying '/etc/netdata/../../usr/lib/netdata/conf.d//health.d/cpu.conf' to '/etc/netdata//health.d/cpu.conf' ... 
Editing '/etc/netdata/health.d/cpu.conf' ...

[root@linuxhelp netdata]# cd health.d/

[root@linuxhelp health.d]# ls -la

[root@linuxhelp health.d]# vim cpu.conf
warn: $this > (($status >= $WARNING)  ? (10) : (20))
crit: $this > (($status == $CRITICAL) ? (20) : (30))

[root@linuxhelp health.d]# netdatacli reload-health

[root@linuxhelp health.d]# vim ram.conf
