 ## Intermittent gaps in metric data collection
 
 During node updates, you may see a 1 to 2 minute gap in metric data for metrics collected from our cluster level collector. This gap is because the node it runs on is being updated as part of a normal update process. It affects cluster-wide targets such as kube-state-metrics and custom application targets that are specified. It occurs when your cluster is updated manually or via autoupdate. This behavior is expected and occurs due to the node it runs on being updated. None of our recommended alert rules are affected by this behavior.

 Refer to [service quotas and limits](../service-limits.md#prometheus-metrics) for default quotas and also to understand what can be increased based on your usage. You can request quota increase for Azure Monitor workspaces using the `Support Request` menu for the Azure Monitor workspace. Ensure you include the ID, internal ID and Location/Region for the Azure Monitor workspace in the support request, which you can find in the `Properties' menu for the Azure Monitor workspace in the Azure portal.
