Missing function in check_mk 2.0 (Migration issue)

[yoloknight]

CMK version:
check_mk 2
OS version:
Ubuntu 20.04
Error message:
none
Output of “cmk --debug -vvn hostname”: (If it is a problem with checks or plugins)
Problem is the function “get_age_human_readable” is not anymore in check_mk 2.0. I cant find the method in the new API. Can someone give me the content of the method or the new version for it in check_mk 2.0?

So it would help me if you only give me the function/method content, what the method does. Then I would copy it 1:1 in a new method with the same name. (if it not would work, then pls give me a another solution)

The easy solution is - the function is not gone. If you take a look at the checks like “acme_certifcates” or “veeam_client” you see the usage of “get_age_human_readable”. This is for classic legacy checks.

If you want to use this function inside a new CMK 2 check you need to make an import at the start.

from cmk.base.check_api import (
    get_age_human_readable,
)

Thanks that was the solution for my problem
If I may ask you one more question, is there a guide for a migration to cmk 2.0?

I have simmilar issues with WATO checks, like “ListofStrings” is also not anymore in check_mk 2.0. Can I also import that from a lib or is there a diffrent approach nessecary?

Ok, I found my problem with “ListOfStrings”.
But still thanks for your help.

The new check API 2.0 has the render class with the timespan methord to achieve the same output.

from .agent_based_api.v1 import render

infotext = render.timespan(seconds)
