Monitor items with dynamic key values

[ryafro]

Hello,

Looking for assistance on monitoring a log file that has a date in the path/name, e.g.

vfs.file.time[/some/path/to/log/file/log_yyyyMMdd.log,change]

Where yyyyMMdd is the current date.

What is the best-practices approach to this issue?

Thanks in advance!

The values for yyyyMMdd should be definetely filled in on agent - if they were filled in on server, that might be delayed due to configuration synchronization.
So, probably a UserParameter, that calls a script. See https://www.zabbix.com/documentation...userparameters

Sorry misread the original post (need my caffeine) not sure if you can use regex or not on that particular item. You may need to write a script that checks the file time stamp, or play around to see if variables/regex work with that item.

Thanks for the responses!

I have 300+ log files I'd need to check in this manner. When I look at Zabbix documentation on external scripts, I see the following:

"Do not overuse external checks! It can decrease performance of the Zabbix system a lot."

What is considered overuse?

[coreychristian]

External scripts are different then parameters.

An external script is run from the zabbix server. A user parameter allows you to use a script locally on the zabbix client.

Thank you for the clarification. I will check the documentation and give it a shot.

Thanks for your help!

Thank you! This seems to work!

Here was my solution:

zabbix_agentd.conf
UserParameter=check_file_age[*],stat -c %Z $1/`date +%Y%m%d`/$2

Testing:
zabbix_get -s hostname -k check_file_age[/home/somepath/,somefile.txt]
