UNIX for Dummies Questions & Answers

Hi,

my VPS was overloaded and inaccessible for some time and i want to ask for help in which log files i need to look, or which tools to setup to monitor and find the cause of repeated hig load?

watched:
/var/log/messages
/var/log/secure
/var/log/httpd/access_log
/var/log/httpd/error_log
/var/log/mysqld.log
/var/log/lfd.log (config server firewall)
/var/log/fail2ban.log

but found no excessive entries
during overload, i cant access server so cant lookup the proceses i think

Unfortunately, to monitor suspicious load... you will have to write your own tool... using perhaps vmstat, iostat, and sar then using cron to run say every 15 minutes... then with time you will have to ajust either execution time or what is monitored...
