Trigger on userparameter not supported

[hijinx]

I hesitate to post this because I feel like I'm missing something.

We are monitoring a large group of linux systems, including capturing some application data from a log file by the use of a custom user parameter via the Zabbix agent.

Recently somebody changed the permissions on one of the systems which caused it to stop capturing the custom application data. The problem this caused was twofold: There was no alert that the data was no longer being collected, and a trigger that should have been set was not, due to the failure of the agent to collect the data from the log file.

I've tried a few different triggers to alert us when the userparameter data collection fails, without success. I know there's a monitoring value for items_unsupported but I was hoping for a host-specific method.

I'm sure there's a good way to do this but I haven't found it.

this is something I am interested in knowing as well.

Have you tried setting a trigger for no data? For example:

{my_template:some.item[].nodata(60)}#0

triggers when the some.data item has received no data for 60 seconds.

Same test with zabbix_sender

Hi,

Can I use this to monitor the correct sent values from zabbix_sender ?

We have a lot of PostgreSQL backup scripts that sends a OK or FAIL via zabbix_sender.
I want to know if the script are sending correcly this values every day and alert us if don't sent nothing.

Best regards.
