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.

Charts

It produces the following charts:

• Sync Proxy Rules in events/s
• Sync Proxy Rules Latency in observes/s
• Sync Proxy Rules Latency Percentage in %
• REST Client HTTP Requests By Status Code in requests/s
• REST Client HTTP Requests By Method in requests/s
• HTTP Requests Duration in microseconds

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.

First, navigate to your plugins directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the setting plugins directory. Once you're in the plugin's directory, switch to the netdata user.

cd /usr/libexec/netdata/plugins.d/
sudo -u netdata -s

You can now run the go.d.plugin to debug the collector:

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