There are two event types in Kubernetes:
- Normal events
- Warning events
See Application Introspection and Debugging for more information on Kubernetes events. AppDynamics reports a subset of these as Cluster Events. They are comprised of Kubernetes warning events and important informational notices concerning state changes in the cluster. An example of a state change is a pod transitioning from a pending to a running state.
This document contains links to Kubernetes documentation. AppDynamics makes no representation as to the accuracy of Kubernetes documentation because Kubernetes controls its own documentation.
A Cluster Event of type warning displays a yellow warning icon. When a Pod, Replicaset, or Deployment gets added, updated, or deleted, otherwise known as a state change, the Cluster Agent reports it as an Info type event and displays a blue info icon.
To access Cluster Event data:
- Click the Servers tab.
- On the navigation bar, select Events. A panel displays a list of events that have been reported from both servers and clusters. To check for specific events, you can use the Filters option.
- Click Add to add a filter and select the desired filters from the available list.
- Click Apply. The list of events is filtered to show only the selected events.
- Double-click the individual Cluster Event. A dialog displays showing a Cluster Event summary.
The Logs tab displays the log details. See Enable Log Collection for Failing Pods.
- Click X to close the dialog.
