[2.3.0] Checkmk Werk 16240 created: Crash on missing thread count on AIX

[//]: # (werk v2) # Crash on missing thread count on AIX key | value ---------- | --- compatible | yes version | 2.3.0b1 date | 2024-02-28T14:12:59+00:00 level | 1 class | fix component | checks edition | cre You're affected if you want to monitor your CPU and the cpu check crashes with something like: ``` File "/omd/sites/YOURSITE/lib/python3/cmk/base/plugins/agent_based/cpu.py", line 48, in parse_cpu count=int(row[3].split("/")[1]), ValueError (invalid literal for int() with base 10: '') ``` We saw this happening on AIX system when the ps information cannot be obtained due to low memory. The parsing is now more resilient against such missing data.
