Kubeproxy

Plugin: go.d.plugin Module: k8s_kubeproxy

Overview

This collector monitors Kubeproxy instances.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

Default Behavior

Auto-Detection

This integration doesn't support auto-detection.

Limits

The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.

Metrics

Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per Kubeproxy instance

These metrics refer to the entire monitored application.

This scope has no labels.

Examples

Basic

A basic example configuration.

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

HTTPS with self-signed certificate

Do not validate server certificate chain and hostname.

jobs:
- name: local
url: https://127.0.0.1:10249/metrics
tls_skip_verify: yes

Troubleshooting

Debug Mode

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
