Sensu Plugin Check-k8s

Description

Sensu plugin used to check the health of pods in a kuberenetes cluster based on namespaces. Setting the label 'pagethis=true' on a namespace will tell sensu to start monitoring it. Results are sent using the sensu socket so that each namespace and group of pods has a seperate check result.

Features

• Check that pod is running
• Check that pod is healthy
• Check that pod is ready
• Check that group of pods are running highly available
• Seperate results per namespace and pod group
• Use in-cluster authentication to connect to the kubernetes api

Usage

check-k8s.rb filter prefix reported_by

# Example
check-k8s.rb pagethis=true mcpamrussell1 sensuclient

Environment variables

• K8S_DEBUG=true - Output the events instead of sending them to sensu
• K8S_READ_TIMEOUT=10 - Set the http connection read timeout (default is 10 seconds)
• K8S_OPEN_TIMEOUT=10 - Set the http connection open timeout (default is 10 seconds)
• K8S_ENDPOINT=localhost:8001 - Set the kubernetes endpoint when not using incluster auth (default is localhost:8000)
