Can not correctly configure trigger to fire only in specific time

[link0876543]

I want to configure this trigger to fire only on specific time. When I use .time trigger function zabbix report `Incorrect trigger expression`.

Check Example 10

https://www.zabbix.com/documentation/1.8/manual/config/triggers

The trigger is used to report when 192.168.1.5 becomes unavailable.

{host1.mydomain.com:fping[192.168.1.5].nodata(1m)}=1&{host1.mydomain.com:fping[192.168.1.5].nodata(1m).time(0)}>000000&{host1.mydomain.com:fping[192.168.1.5].nodata(1m).time(0)}<060000

Hello and welcome to Zabbix forums!

There is a problem in the expression part where functions are used. Don't use two functions in a row like this: .nodata(1m).time(0)

Try the following expression:

{host1.mydomain.com:fping[192.168.1.5].nodata(1m)}=1&{host1.mydomain.com:fping[192.168.1.5].time(0)}>000000&{host1.mydomain.com:fping[192.168.1.5].time(0)}<060000

Hope this helps!

When I enter this code I receive error from Zabbix:

Incorrect trigger expression. Check expression part starting from "1&{host1.mydomain.com:fping[192.168.1.5].time(0)}>000000&{host1.mydomain.com:fping[192.168.1.5].time(0)}<060000".

What version of Zabbix are you using?

If 2.4.x then try the following:

{host1.mydomain.com:fping[192.168.1.5].nodata(1m)}=1 and {host1.mydomain.com:fping[192.168.1.5].time()}>000000 and {host1.mydomain.com:fping[192.168.1.5].time()}<060000

Expression syntax was changed a bit there.

That worked.

So what was the cause of the problem? Was it new sytax of triggers in new version of Zabbix?

[ingus.vilnis]

Seems you are using 2.4 then but was referring to documentation of 2.2.

The problem in your case was that you were using trigger expressions with logical AND "&" but starting from 2.4. you have to use "and" for this.
