Here are a few command used daily to check on apache and what it’s doing…
watch "netstat -plan|grep :80|awk {'print \$5'} | cut -d: -f 1 | sort | uniq -c | sort -nk 1"
output
Every 2.0s: netstat -plan|grep :80|awk {'print $5'} | cut -d: -f 1 | sort | uniq -c | sort -nk 1 Tue Mar 16 02:49:31 2010
1 0.0.0.0
1 69.167.132.171
1 71.2.208.233
3 98.238.142.3
To check the number of site connections, you can use:
/usr/bin/lynx -dump -width 500 http://127.0.0.1/whm-server-status | awk 'BEGIN { FS = " " } ; { print $12 }' | sed '/^$/d' | sort | uniq -c
output looks like
2 host.myserver.com
5 domain.com
1 process
1 slot
1 VHost
To check for the busiest site on the server;
/usr/bin/lynx -dump -width 500 http://127.0.0.1/whm-server-status | grep GET | awk '{print $12}' | sort | uniq -c | sort -rn | head
output looks like
69 domain.com
33 host.domain.com
To check for the busiest script on the server;
/usr/bin/lynx -dump -width 500 http://127.0.0.1/whm-server-status | grep GET | awk '{print $14}' | sort | uniq -c | sort -rn | head
