How to confirm Existence and Permissions of System Log Files
For each log file LOGFILE referenced in /etc/syslog.conf or /etc/rsyslog.conf, run the commands:
# touch LOGFILE
# chown root:root LOGFILE
# chmod 0600 LOGFILE
Syslog will refuse to log to a file which does not exist. All messages intended for that file will be silently discarded, so it is important to verify that all log files exist. Some logs may contain sensitive information, so it is better to restrict permissions so that only administrative users can read or write logfiles.
cPanel Daily Process Log (formerly CPU/Memory/MySQL Usage)
(Main –>> Server –>> Daily Process Log)
This feature displays information about your server’s consumption of processing power and memory, averaged over the course of the selected day.
The information is divided into rows and columns. Each row represents a different process running on your server while each column represents the processes’ associated parameters.
The processes running on your server will depend on how you have configured WHM and what other daemons and applications you install on your server.
The column information is divided into 5 categories:
User — Displays the name of the user running the process. For example, if you are logged into your server as “root,” then that username will appear in this field for any processes you initiate.
Domain — Displays the domain name associated with your cPanel user accounts.
%CPU — Displays the average daily percentage of the CPU’s processing power used by the corresponding process.
%MEM — Displays the average daily percentage of RAM used by the corresponding process.
MySQL Processes — Displays the average number of MySQL processes associated with the corresponding process for today.
