CPU

CPU Collector

To collect information about the number of CPU cores on a host, use the cpu collector.

Parameters

None.

Example Collector Definition

apiVersion: troubleshoot.sh/v1beta2
kind: SupportBundle
metadata:
  name: cpu
spec:
  hostCollectors:
    - cpu: {}

Included Resources

The results of the cpu collector are stored in the host-collectors/system directory of the support bundle.

`cpu.json`

Example of the resulting JSON file:

{"logicalCount":4,"physicalCount":2}

CPU Analyzer

The cpu analyzer supports multiple outcomes by validating the number of CPU cores, for example:

count < 32: Less than 32 CPU cores were detected.
count > 4: More than 4 CPU cores were detected.

Example Analyzer Definition

apiVersion: troubleshoot.sh/v1beta2
kind: SupportBundle
metadata:
  name: cpu
spec:
  hostCollectors:
    - cpu: {}
  hostAnalyzers:
    - cpu:
        checkName: "Number of CPUs"
        outcomes:
          - fail:
              when: "count < 2"
              message: At least 2 CPU cores are required, and 4 CPU cores are recommended
          - warn:
              when: "count < 4"
              message: At least 4 CPU cores are recommended
          - pass:
              message: This server has at least 4 CPU cores

Collect and analyze information about the number of CPU cores.
