How to set GOMAXPROCS parameter for all node-exporter pods

Problem

• How to set the GOMAXPROCS parameter in clusters on PMK v5.6?

Environment

• Platform9 Managed Kubernetes - v5.6 or Less

Procedure

• Edit the node-exporter daemonset in the pf9-monitoring namespace

kubectl get ds node-exporter -n pf9-monitoring -o yaml

• In the containers section of the spec , add this environment variable as below:

env:

    - name: GOMAXPROCS

      value: 1

Additional Information

• v.1.6.0+ of node-exporter has GOMAXPROCS runtime environment as 1 by default.
• PMK releases v5.9 and greater have node-exporter with v1.6.1 that already contains the default setting of GOMAXPROCS parameter.
