Note

Requirements

The WhaTap Kubernetes agent 1.7.6 or later is required. Timeline data is provided from the time point collected in version 1.7.6 or later.

The Pod Timeline menu provides the feature to visually trace state changes of Pod over time. You can visually see when the terminated Pod was terminated, and which state Pod was in at a specific time point. This allows you to analyze the past status, identify the causes of issues in the cluster, and monitor the operational stability.

Basic screen guide​

After entering the Pod Timeline menu, select Filter key and Filter value to view the data. You can see the Pod list collected in the last 1 hour. You can visually see the state changes of Pod along the time axis.

If you hover your mouse over each time zone, the start and end times of it and Pod status (Running, Pending, Succeeded, Failed) appear.

Pod Timeline1

You can adjust the time range by dragging the zone on the timeline. Set a desired period to check the past data.

Pod Timeline2

Additionally, when you select a specific period, you can check the Pod status during the period in detail through Display Detail. For more information, see the Pod timeline detail guidance.
