Parsing of section docker_container_diskstat failed

Hello,

I have added two Docker containers to Check_MK 2.0, and I am encountering the following error message in the Check_MK Discovery process:

“Parsing of section docker_container_diskstat failed.”

Additionally, I have noticed that two services are missing and cannot be located: CPU Utilization and Disk IO Summary.

Here are some details about my environment:

  • Check_MK Version: 2.0.0p34
  • Operating System Version: 9.2

Here’s the full error message:

Error message: Parsing of section docker_container_diskstat failed

File “/omd/sites/PRODOCI/lib/python3/cmk/base/checkers/host_sections.py”, line 392, in _get_parsing_result
parsed_result = section.parse_function(data)

devices_by_number[major_minor][diskstat_key] = value

I’m seeking assistance in identifying the possible cause of this issue. Any insights or suggestions would be greatly appreciated.

Thanks,
Khaled
