Kube-proxy monitoring with Netdata

Kube-proxy is a network proxy that runs on each node in your cluster, implementing part of the Kubernetes Service.

This module will monitor one or more kube-proxy instances, depending on your configuration.

Metrics

All metrics have "k8s_kubeproxy." prefix.

Configuration

Edit the go.d/k8s_kubeproxy.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/k8s_kubeproxy.conf

Needs only url to kube-proxy metric-address. Here is an example for several instances:

jobs:
- name: local
url: http://127.0.0.1:10249/metrics

- name: remote
url: http://203.0.113.1:10249/metrics

For all available options please see module configuration file.

Troubleshooting

To troubleshoot issues with the k8s_kubeproxy collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

  • Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].

    cd /usr/libexec/netdata/plugins.d/
  • Switch to the netdata user.

    sudo -u netdata -s
  • Run the go.d.plugin to debug the collector:

    ./go.d.plugin -d -m k8s_kubeproxy
