Date Macro

[ferri]

Hello everybody,

I have a problem and I hope someone could help me.
I have an active Zabbix agent item that gets back Windows log:
eventlog[Application,,,"NTBackup",8017]
With that log, I can check whether the backup succeded or not.

Then, I created a trigger which fire if the severity log is equals to 4:
({Sauvegardes:eventlog[Application,,,"NTBackup",8017].logseverity(0)}=4) & ({Sauvegardes:eventlog[Application,,,"NTBackup",8017].nodata(3600)}=0)

The problem is the following:
I don't have this log every day, so if I have one with high severity (4), the trigger will fire, but the following day, It will continue to fire while there is no log.

I would like to link the item with the present date. I have seen different macros like ITEM.LOG.DATE, ITEM.LOG.AGE, etc... but I don't know how can I use them.

Thank you very much

I saw that it is impossible to use such macros in trigger expression but there is some function like date(). I don't know how to use it and I don't know what does it get me back.

Is there a command line to test a trigger expression on the zabbix server (like zabbix_get)?

Thank you
