Monitoring Hosting.

[zerg]

Hello.

I'am need some expirience about carefully monitoring Hosting servers.
Now i'am using:

OS: freebsd 6.2
Zabbix: zabbix-1.4,1
Apache: apache-2.0.59

We have some site's on jails (virtualiztion system on FreeBSD). I'am monitoring this sites with zabbix_agentd such as:

#cat zabbix_agentd.conf|grep Par
UserParameter=site.count,sudo psj |grep www.|grep inetd| awk /www/'{print ($2)}'|wc -l
UserParameter=site.count_smtp,sudo psj |grep www.|grep inetd| awk /www/'{print ($2)}' |xargs -n1 /usr/local/libexec/nagios/check_smtp -t 20 -f "[email protected]" |grep OK |wc -l
UserParameter=site.count_http,sudo psj |grep www.|grep inetd| awk /www/'{print ($2)}' |xargs -n1 /usr/local/libexec/nagios/check_http -u /monitor/index.shtml |grep OK |wc -l

Then i'am create Template with Triggers, Actions, Items etc

If you see i'am using nagios-plugins (check_http, check_smtp), i'am think this is bad.

Have anyone sucsess story about monitoring Hosting Servers?
