“CPU/Memory/MySQL Usage” showing blank cPanel:
This is a common error in all cPanel versions, The main cause of this error is related to the utility that produces the statistics in cPanel.
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 cPanel server,
root@iserversupports13 [/etc/cron.hourly]# crontab -l 0 6 * * * /usr/local/cpanel/scripts/exim_tidydb > /dev/null 2>&1 30 5 * * * /usr/local/cpanel/scripts/optimize_eximstats > /dev/null 2>&1 2,58 * * * * /usr/local/bandmin/bandmin 0 0 * * * /usr/local/bandmin/ipaddrmap 18 3 * * * /usr/local/cpanel/scripts/upcp --cron 0 1 * * * /usr/local/cpanel/scripts/cpbackup 0 2 * * * /usr/local/cpanel/bin/backup 35 * * * * /usr/bin/test -x /usr/local/cpanel/bin/tail-check && /usr/local/cpanel/bin/tail-check 45 */4 * * * /usr/bin/test -x /usr/local/cpanel/scripts/update_mailman_cache && /usr/local/cpanel/scripts/update_mailman_cache 30 */4 * * * /usr/bin/test -x /usr/local/cpanel/scripts/update_db_cache && /usr/local/cpanel/scripts/update_db_cache 45 */8 * * * /usr/bin/test -x /usr/local/cpanel/bin/optimizefs && /usr/local/cpanel/bin/optimizefs 30 */2 * * * /usr/local/cpanel/bin/mysqluserstore >/dev/null 2>&1 15 */2 * * * /usr/local/cpanel/bin/dbindex >/dev/null 2>&1 15 */6 * * * /usr/local/cpanel/scripts/autorepair recoverymgmt >/dev/null 2>&1 */5 * * * * /usr/local/cpanel/bin/dcpumon >/dev/null 2>&1 11 2 * * * /usr/local/cpanel/whostmgr/docroot/cgi/cpaddons_report.pl --notify 3,18,33,48 * * * * /usr/local/cpanel/whostmgr/bin/dnsqueue > /dev/null 2>&1 4 0 * * * cd /usr/local/cpanel/whostmgr/docroot/cgi/fantastico/scripts/ ; /usr/local/cpanel/3rdparty/bin/php cron.php > /dev/null 2>&1 44 23 * * * /usr/local/cpanel/3rdparty/bin/freshclam --quiet --no-warnings
In that the cron below compiles the logs for the Usage page,
*/5 * * * * /usr/local/cpanel/bin/dcpumon >/dev/null 2>&1
and this is set to run every five minutes, every hour.
So for solving this issue you need restart the crond. For that run the command,
/etc/init.d/crond restart
root@iserversupports13 [~]# /etc/init.d/crond restart Stopping crond:[OK] Starting crond:[OK] root@iserversupports13 [~]#
This will fix the issue.
