Object Manifest Information

Home > Select Project > Cluster > Object Manifest Information



WhaTap Master Agent 1.5.5 or later is required. If the version is less than 1.5.5, the master meta info screen appears.

The Kubernetes Master Agent automatically collects manifests for objects such as Pods, services, and ReplicaSets in clusters once a day. The data is stored by date, allowing users to easily check the cluster status as of a specific date. The collected data can be compared by date, making it easy to identify changes in clusters over time.

Additionally, you can freely set the collection time zone by specifying the container environment variables before deployment of the Kubernetes Master Agent. For more information about the configuration, see the guide to Container environment variables.

Container environment variables

  • store_k8s_object_manifest_enabled

    Default true

    The object manifest collection feature is enabled. The default value is true, the collection feature is enabled without any further settings.

  • store_k8s_object_manifest_timezone

    Default UTC

    Set the time zone for collection of object manifests. If there is no separate setting, collection starts at midnight based on UTC by default.

    • Can be set as a region-based time zone or in GMT offset format.

    • Supports a precise time setting in minutes.

      For example, a non-standard time zone for a specific region can be specified by setting it to GMT+0810.

  • store_k8s_object_manifest_max_fetch_limit

    Default 50

    Set the number of objects to request to the cluster at a time. If there is no separate setting, 50 items are requested upon request based on the default value of 50.

    For example, when setting the option 30 in a cluster with a total number of Pods of 90, pods are requested 3 times for 30 pods each.

List of Object Manifest saving times

  • You can see the list of the times saved for object manifests on the left. Object manifests are automatically saved at a specified time per day.

  • The object manifest saving time can be changed by modifying the value of the master agent's container environment variable, store_k8s_object_manifest_timezone.

  • Object manifests are saved at a scheduled time per day, but are also additionally saved when any warning events occur.


The warning events in which the object manifests are saved indicate Kubernetes event objects of Warning type.

Linking the Kubernetes events

When you click Warning icon in the Object manifest detail window, Kubernetes events appear as follows:

Kubernetes event integration


The Kubernetes event linking is supported by WhaTap Master Agent 1.6.1 or later.

Comparison of object manifests

When Icon Compare is enabled, you can compare two saved object manifests by selecting in the saved time list. Any changes are highlighted.
