How to check for time drift?

[Crazy Marty]

I'd like to create a trigger (in Zabbix 1.6.1) that compares a "sacred machine"'s localtime to another monitored machine's localtime. If I create a trigger like:

({T_Linux_time:system.localtime.last(0)}-{Timehost:system.localtime.last(0)})>3600

in template "T_Linux_time", Zabbix complains that I can't mix template hosts (I think it means templates *and* hosts).

I just want to make sure none of the monitored machines drift too far.... I can't rely on having ntp running on them all, because they're not all physical machines (ntp does not play well on Xen or VMware virtual machines).

Any ideas?

you can check localtime against zabbix server time (i think fuzzytime function).
so if you have ntpd on zabbix server, that should work nicely.

Would you elaborate on that?

Check if client local time is in sync with Zabbix server time

Use of function fuzzytime():

{MySQL_DB:system.localtime.fuzzytime(10)}=0

The trigger will change to the problem state in case when local time on server MySQL_DB and Zabbix server differs by more than 10 seconds.

Thanks! Ones has only to take care of time on Zabbix server
