[ZBX 5.4] Custom Trigger Prototype = Filesystem 100% Full

[omar.cacciotti]

Hello everybody!
Thank you in advance for any suggestions:

I will try to explain my issue.

SCOPE: Build a trigger prototype for Filesystems at 100%. This trigger must be an "evolution" of standard template triggers:

Step1 —> /: Disk space is low (used > 80%) <--- this is the default template trigger that's working
Step2 —> /: Disk space is critically low (used > 90%). <--- this is the default template trigger that's working
Step3 ---> /: Disk space is 100% FULL (used = 100%). <--- this is the custom that isn't working

After many tries I simplified the rules:

{my_host:vfs.fs.size[{#FSNAME},pused].last()}={$VFS.FS.PUSED.MAX.FULL:"{#FSNAME}"}


Where VFS.FS.PUSED.MAX.FULL = 100



I full cloned the AVERAGE trigger and modified some data:



And this is inherited at host level:



Any suggestion on how to solve the issue?
This trigger not appears on the monitoring dashboard

tnx!

What is the client returning for percent-used (pused) on that volume?

Your trigger is written so that it will only evaluate to a problem when the value returned is exactly equal to 100. I haven't tested whether the zabbix_agent's tests include the filesystem "minfree" setting, but it's possible (in some cases) that your volume may be full without returning exactly 100 as the percent used.

I would go with >99% (or 99.8 or similar) instead of =100
