Cannot evaluate function error

[royc]

Hello

I'm getting 'Cannot evaluate function' error on this trigger expression:

({TRIGGER.VALUE}=0&{host1:logrt[/usr/local/schedulers/activeeon/proactivescheduler/logs/Scheduler.log,ERROR,,20].count(1d)}>0)|({TRIGGER.VALUE}=1&{host1:logrt[/usr/local/schedulers/activeeon/proactivescheduler/logs/Scheduler.log,ERROR,,20].nodata(1d)}=0)

host1 is a valid host name.

Any ideas?

Hi,

When I hit these types of issues, I open my favorite editor and copy and paste the entire expression to it. Next, I paste back one expression at a time and test it. For example "{TRIGGER.VALUE}=0" Next,

({TRIGGER.VALUE}=0&{host1:logrt[/usr/local/schedulers/activeeon/proactivescheduler/logs/Scheduler.log,ERROR,,20].count(1d)}>0)

As I'm a newbie too, I thought Zabbix 2.x is using boolean names such as and, or, not rather than the old &, |

Please try:

({TRIGGER.VALUE}=0 and {host1:logrt[/usr/local/schedulers/activeeon/proactivescheduler/logs/Scheduler.log,ERROR,,20].count(1d)}>0)

FWIW, I once tried uppercase AND and Zabbix barked at me. So, I now use lowercase.

HTH.

Thanks Pablo, it was actually a curroped file that couldn't be opened!

[pablos]

Good find! Was the error message in the Zabbix Agent's log?

Thanks

No it wasn't I just attempted to open it and got a prompt it's a binary when the extension is .log so clearly a problem with the file. Deleting the file and allowing the server regenerating a new one resolved it.

Excellent troubleshooting!

You're using the same strategy I use: break the problem down and start at the beginning. If step 1 works, go to the next. Usually works well. ha!

ha he, the good thing about being a newbie at something is that you do just that

It never fails either newbie or oldbie ...
