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. When you deploy a monitoring agent to the worker nodes in your cluster, Monitoring is already automatically enabled to detect and scrape the data and then display them 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.

   Note that it might take a few minutes for your 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. Note that the NGINX Ingress dashboard does not appear until there is data available. This process can take some time. The NGINX Ingress dashboard is visible only when the monitoring agent finds nginx_ingress_controller_requests metrics value. These metrics are exposed when you send queries 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.
