“CPU/Memory/MySQL Usage” page blank

This is a common error in all cPanel releases. This is mostly caused because of the utility that actually generates the statistics. When cPanel is installed, several entries are added into crontab for the root user. The following is a list of the default crontab entries from a freshly installed cPanel server:

[email protected] [/etc/cron.hourly]# crontab -l | grep dcpumon 

*/5 * * * * /usr/local/cpanel/bin/dcpumon >/dev/null 2>&1
[email protected][/etc/cron.hourly]#

 

The dcpumon is the daemon that compiles the logs for the usage page.

If your Usage page is blank, it is normally because this utility is not running on the schedule that it is supposed to.

The above crontab entry for dcpumon is set to run every five minutes, every hour.

For solving this issue,

The most common resolution for this issue is to restart crond:

[email protected] [~]# /etc/init.d/crond restart
Stopping crond:[OK]
Starting crond:[OK]
[email protected] [~]#

The restart of cron should force all crontab entries to be processed normally again.

If after this you are still not seeing statistics on the Usage page, you should force a cpanel update from command line with the command,

/scripts/upcp –force

This should download and install a new copy of the dcpumon binary.
