Event monitoring

This article covers the installation of Kubernetes Event Exporter. This add-on is used for monitoring events within a Kubernetes cluster.

Before using the add-on, first install Loki.

The installation of the add-on consists of three steps:

  1. Download the Helm chart and configuration file..
  2. Fill out the configuration file.
  3. Install the kubernetes-event-exporter chart using helm in the Kubernetes cluster.

Step 1: Download the Helm chart and configuration file.

To install via the internet, obtain the configuration file values-kubernetes-event-exporter.yaml by executing the following command:

helm repo add elma365 https://charts.elma365.tech
helm repo update
helm show values elma365/kubernetes-event-exporter > values-kubernetes-event-exporter.yaml

Obtaining the configuration file for installation in an closed environment without internet access

  1. On a computer with internet access, download the latest version archive of the kubernetes-event-exporter hart from the BRIX repository by executing the following command:

helm repo add elma365 https://charts.elma365.tech
helm repo update
helm pull elma365/kubernetes-event-exporter

 

  1. Copy the chart archive kubernetes-event-exporter-X.Y.Z.tgz to the server where installation will be performed.
  2. Unpack the chart and copy the default configuration file values.yaml into values-kubernetes-event-exporter.yaml:

 

tar -xf kubernetes-event-exporter-X.Y.Z.tgz
cp kubernetes-event-exporter/values.yaml values-kubernetes-event-exporter.yaml
 

Step 2: Fill out the configuration file

Filling out the values-kubernetes-event-exporter.yaml configuration file for installation of kubernetes-event-exporter

kubernetes-event-exporter:
enabled: true
config:
logLevel: info
logFormat: json
maxEventAgeSeconds: 60
kubeQPS: 100
kubeBurst: 500
metricsNamePrefix: event_exporter_
route:
routes:
- match:
- receiver: "dump"
receivers:
- name: "dump"
stdout: {}

 

Filling out the the connection parameters for installation in a closed environment without internet access

To connect to the private registry:

  1. Download the ELMA365 images and upload them to your local image registry. For more details, see Download BRIX images.
  2. Specify the address and path for the image.registry parameter.
  3. Specify the name of the secret that contains access rights to the private registry in the image.pullSecretsparameter. The secret should be manually created and encoded in Base64.

kubernetes-event-exporter:
## Parameters for connection to the private registry
 image:
## address and path for the private registry
   registry: registry.example.com
   repository: bitnami/kubernetes-event-exporter
   tag: 1.7.0-debian-12-r4
   pullPolicy: IfNotPresent
   pullSecrets: []

Where the format of repositoryis: addres is registry.example.com
 

Step 3: Install the kubernetes-event-exporter chart using helm in the Kubernetes cluster

Install the kubernetes-event-exporter chart to namespace monitoring.

For installation via the internet, use the following command:

helm upgrade --install -n monitoring kubernetes-event-exporter elma365/kubernetes-event-exporter -f values-kubernetes-event-exporter.yaml
 

For offline installation without internet access, navigate to the directory with the downloaded chart and execute the command:

helm upgrade --install kubernetes-event-exporter ./kubernetes-event-exporter -f values-kubernetes-event-exporter.yaml -n monitoring
