Overview

Kube Proxy manages networking rules on nodes to forward requests to services and pods.

Why it’s Useful

  • Detects service connectivity failures.
  • Tracks proxy health and performance.
  • Ensures load balancing across pods.

What Users Can Do

  • Monitor kube-proxy process stability.
  • Debug service access issues.
  • Verify iptables/IPVS rules are functioning.

Steps to Configure

  1. Get the existing ConfigMap.
    kubectl get cm opsramp-k8s-infra-metric-user-config -n <agent-installed-namespace> -o yaml
  2. Edit the ConfigMap.
    kubectl edit cm opsramp-k8s-infra-metric-user-config -n <agent-installed-namespace>
  3. Locate the kube_proxy section in ConfigMap.
    k8s_cluster:
  enabled: true
  config:
    scrape_interval: "2m"
  4. Update the required parameters.
  5. Save and apply the changes.
