Monitoring of infrastructure

Prometheus is a monitoring tool designed to collect and analyze system operation data. Monitoring facilitates maintaining the stability and reliability of the infrastructure.

Beforehand, install the monitoring tools. Then configure the internal components of Kubernetes to transmit metrics to Prometheus.

The setup consists of four steps:

  1. Configure the kube-proxy component.
  2. Configure the kube-scheduler component.
  3. Configure the etcd component.
  4. Configure the kube-controller-manager component.

Step 1: Configure the kube-proxy component

  1. Make changes to the ConfigMap;

kubectl edit cm/kube-proxy -n kube-system

  1. Set the value 0.0.0.0:10249 in hte line metricsBindAddress;

kind: KubeProxyConfiguration
metricsBindAddress: "0.0.0.0:10249"

  1. Apply the changes.

kubectl -n kube-system rollout restart daemonset kube-proxy

Step 2: Configure the kube-scheduler component

  1. Make changes to the kube-scheduler.yaml manifest file;

nano /etc/kubernetes/manifests/kube-scheduler.yaml

  1. Set the value 0.0.0.0 in the line --bind-address. The configuration will be applied automatically after saving the manifest.

- --bind-address=0.0.0.0

Step 3: Configure the etcd component

  1. Make changes to the etcd.yaml manifest file;

nano /etc/kubernetes/manifests/etcd.yaml

  1. Set the value http://0.0.0.0:2381 in the line --listen-metrics-urls. The configuration will be applied automatically after saving the manifest.

- --listen-metrics-urls=http://0.0.0.0:2381

Step 4: Configure the kube-controller-manager component

  1. Make changes to the kube-controller-manager.yaml manifest file:

nano /etc/kubernetes/manifests/kube-controller-manager.yaml

  1. Set the value 0.0.0.0 in the line --bind-address. The configuration will be applied automatically after saving the manifest.

- --bind-address=0.0.0.0

Once the component configurations are set, their metrics will be available in Prometheus.

Data vizualisation

In the data visualization software Grafana, you can view charts with monitoring results.

Custom dashboards are also available. To activate them, enable dashboards.enabled in the values  file for the installation of monitoring tools.
