How to check if agent versions are at least the monitoring site version?

[BSBS]

We have multiple Check_MK sites in the company, some of which monitor the same machines.
Their versions do not always line up exactly.
Sometimes one is newer, sometimes the other.

I can’t find a configuration where these 3 things are true:

1. The agent version check under Setup → Services → Service monitoring rules → Checkmk Agent installation auditing is enabled
2. None of the Check_MK sites reports a mismatched version
3. The version check doesn’t need to be manually reconfigured during an update

I tried just checking “at least” and nothing under it, but that’s as good as disabling the check.
Is there any solution?

Hi BSBS,

try using the environment variable $OMD_VERSION. I don’t know if it really exists, but if not, I’m sure that Tribe29 can implement it in an upcoming version if we provide them this feedback.

I’m getting a crash report with the following error when I try that:
ValueError (invalid literal for int() with base 10: ‘$OMD_VERSION’)

Similar error if I write $OMD_VERSION$.

I also tried “$HOSTNAME$” in there, to see if any variable works and I’m getting a similar error again.
Looks like variables aren’t supported in that field at all.
