Observing Kubernetes Ingress

Setting up monitoring with IBM Cloud Monitoring

Gain operational visibility into the performance and health of your Kubernetes Ingress ALBs by deploying a Monitoring agent to your worker nodes to forward metrics to IBM Cloud® Monitoring. After you deploy the monitoring agent to the worker nodes in your cluster, monitoring automatically detects and scrapes the data and then displays it in your IBM Cloud Monitoring dashboard.

1. Provision an instance of IBM Cloud Monitoring.

2. Configure a monitoring agent in your cluster.

   1. Select your monitor from the Monitoring page.
   2. Click Monitoring sources.
   3. Follow the instructions for installing a monitoring agent to your cluster.

   It might take a few minutes for the agent to finish installing.

3. In the Monitoring console, click Open Dashboard for the instance that you provisioned.

4. In the Monitoring UI, click Dashboards > Applications > NGINX Ingress. The NGINX Ingress dashboard does not appear until data is available, which can take some time. The dashboard is visible only when the monitoring agent finds the nginx_ingress_controller_requests metric. These metrics are exposed when you send requests to the hosts that are defined in your Ingress resources.

   The default Ingress monitoring filters can produce a high volume of metrics, which can incur additional billing. Add the filter exclude: nginx_ingress*bucket to reduce costs by excluding some metrics while retaining the default metrics needed for the NGINX dashboard.
