Greptile Overview

Greptile Summary

This PR removes an 8-line useEffect hook that automatically reset filter state whenever the stagedResourceUrn changed in the action center monitor field filters. Previously, selecting different resources from the tree would reset filters to their default values, creating a poor user experience. The change enables filters to persist across tree selections, allowing users to maintain their filter preferences while exploring different resources.

The implementation is clean and straightforward:

• Removed lines 175-183 which contained the useEffect that called resetToInitialState() on stagedResourceUrn changes
• Filter state is managed via URL query params using the useMonitorFieldsFilters hook
• The stagedResourceUrn is still passed to the API query to fetch filtered data for the selected resource
• All other filter functionality (apply, reset, clear) remains intact

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is extremely simple and low-risk: it removes 8 lines of code that were causing undesired behavior. The filter state management continues to work through URL query params, and the stagedResourceUrn is still properly passed to API calls to fetch the correct data. No new logic is introduced, only the auto-reset behavior is removed.
• No files require special attention
