Node Dashboard¶

Click on "Overview" to access the Node's dashboard.

Node Health Timeline The node health timeline presents the health of the node over the specified time period. This view can be critical for Infrastructure teams to determine when and how long a node was unhealthy.

In the example below, the node has been healthy without issues in the specified time period.

Pod Count by Status A timeline view is presented showing the count of pods scheduled on the node organized by their status (Running or Error).

In the example below, there are a total of 13 pods on this node with zero pods in Error state.

Resource Utilization Timeline

Node Resource (CPU, Memory and Storage) utilization trends are presented with a view into current utilization as well.

For CPU and Memory, both "Committed" and "Actual" utilization data is presented. This information can be critical for infrastructure admins in determining if the node is correctly resourced or not.
