开源软件介绍(OpenSource Introduction):

Kubernetes Event Exporter

Build Status License

Kubernetes events to Prometheus bridge.

A Collector that can list and watch Kubernetes events, and according to events' occurrence, determine how long the event lasts. The information is then translated into metrics.

Metrics Overview

  1. kube_event_count Count of kubernetes event that was seen for the last hour. The metric value is the same as the count property of Event object in the cluster.
    kube_event_count{involved_object_kind="Deployment",involved_object_name="event-exporter",involved_object_namespace="default",name="event-exporter.1640452bd04fc7bf",namespace="default",reason="ScalingReplicaSet",source="/deployment-controller",type="Normal"} 1
    
  2. kube_event_unique_events_total Total number of kubernetes unique event that happened for the last hour.
    kube_event_unique_events_total{involved_object_kind="Deployment",involved_object_name="event-exporter",involved_object_namespace="default",name="event-exporter.1640452bd04fc7bf",namespace="default",reason="ScalingReplicaSet",source="/deployment-controller",type="Normal"} 1
    
  3. event_exporter_versionInformation of the event exporter that was built
    event_exporter_build_info{branch="v1.0",build_date="2020-10-22T10:11:29Z",build_user="Caicloud Authors",go_version="go1.13.15",version="v1.0.0"} 1
    

Getting Started

Build

$ VERSION=v1.0.0 REGISTRY=docker.io make build

If you want to get more information about flag options,please refer to Makefile in our repository

Run

running outside Kubernetes (Exporter will search for kubeconfig in ~/.kube)

$ ./event_exporter  --kubeConfigPath=$HOME/.kube/config

running inside Kubernetes (Exporter will use Kubernetes serviceaccount)

$ ./event_exporter

Check the metrics

curl http://<pod-ip>:9102/metrics

General Flags

Name Example Description
kubeMasterURL --kubeMasterURL= Optional. The URL of kubernetes apiserver to use as a master
kubeConfigPath --kubeConfigPath=$HOME/.kube/config Optional. The path of kubernetes configuration file
eventType --eventType=Warning --eventType=Normal Optional. List of allowed event types. The default value is Warning type
port --port=9102 Optional. Port to expose event metrics on (default 9102)
version --version Print version information

Use Kubernetes

You can deploy this exporter by using the image caicloud/event-exporter:${VERSION} in k8s cluster, the available versions can be got from the releases.

Deploy

kubectl apply -f deploy.yml

Then check the pod status:

kubectl get pods | grep event
