Trigger on NOT receiving Keepalive traps

[Borrie]

Hi All,

I'm having a problem triggering on 'not receiving keepalives'. I'm familliar with the nodata() function, but in my specific situation i'm not able to use it. Hopefully you can give me some hints after explaining what goes wrong;

- Keepalive traps are coming in and are send into zabbix using the zabbix_sender binary.
- The traps are showing up in Zabbix (latest data) and are stored as 'Text'.

First i tried to use the str() function to look for 'Keepalive' in that specific text:

({snmptraps:snmptraps.str(Keepalive)}=1) & ({snmptraps:snmptraps.nodata(60)}=0))

Unfortunately Zabbix does not support use of the str() function on Text datatypes.

Does anyone know how to solve this little annoying problem? In the manual i cannot find a suitable function to solve this.

Thanks for the effort!

Wouter
