Command to Detect Overlapping Monitor Configurations

[nicolastakashi]

Description

It would be extremely useful to have a command that identifies overlapping monitoring configurations in the cluster. This feature would help prevent redundant or conflicting monitoring setups by detecting scenarios where multiple monitoring objects select the same resources.

Examples of Overlaps:

1. ServiceMonitors: Two or more ServiceMonitor objects selecting the same service and port.
2. PodMonitors: Two or more PodMonitor objects targeting the same set of pods and ports.
3. Mixed Overlaps: A ServiceMonitor and a PodMonitor that, in the end, select the same pods, potentially through indirect label selection.

Use Case

This functionality would streamline troubleshooting and improve the efficiency of monitoring configurations by identifying and resolving potential conflicts proactively.

Proposed Implementation

Introduce a command or utility to:

• Analyze and compare label selectors in monitoring resources.
• Report overlaps in a clear, actionable format.

Hi @nicolastakashi I would like to work on this as well.
