Monitoring Linux Workers and Workloads

This topic lists VMware Tanzu Kubernetes Grid Integrated Edition (TKGI) components and integrations you can use to capture logs and metrics about your Kubernetes worker nodes and workloads.

Overview

To monitor Kubernetes worker nodes and workloads in your TKGI deployment, you can enable one or more of the following components and integrations in the Tanzu Kubernetes Grid Integrated Edition tile > In-Cluster Monitoring:

Name	Type	Link
Sink resources	TKGI component	Sink Resources, below.
Wavefront	External integration	VMware Tanzu Kubernetes Grid Integrated Edition Integration in the Wavefront documentation. Or send metrics to Wavefront with a metric sink.
vRealize Operations	External integration, with cAdvisor	cAdvisor on GitHub VMware vRealize Operations Management Pack for Container Monitoring

When running on worker nodes, these components and integrations are visible to both TKGI admins and cluster users, such as developers.

To enable sink resources, Wavefront, or vRealize Operations integration, follow the instructions in In-Cluster Monitoring for your IaaS:

• Installing Tanzu Kubernetes Grid Integrated Edition on vSphere
• Installing Tanzu Kubernetes Grid Integrated Edition on vSphere with NSX-T
• Installing Tanzu Kubernetes Grid Integrated Edition on GCP
• Installing Tanzu Kubernetes Grid Integrated Edition on AWS
• Installing Tanzu Kubernetes Grid Integrated Edition on Azure

For information about monitoring TKGI and TKGI-provisioned cluster VMs on Linux, see Monitoring TKGI and TKGI-Provisioned Clusters.

• Logging Windows Worker Clusters and Workers

Sink Resources

In TKGI, you can deploy log sinks and metric sinks to monitor your Kubernetes worker nodes and workloads that are running on them.

To deploy a log or a metric sink:

1. Enable sink resources in the Tanzu Kubernetes Grid Integrated Edition tile > In-Cluster Monitoring. You can enable both log and metric sink resources or only one of them.
2. (Optional) Enable Node Exporter on worker nodes by selecting the Enable node exporter on workers checkbox.
3. Create sink resources. For instructions, see Creating and Managing Sink Resources.
