Summary of Changes
Hello @dalmia007, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request addresses a bug in the live block view where usage information was not updating dynamically. The change ensures that the monitoring system's cache is cleared before each refresh cycle, guaranteeing that the displayed usage data is always current.

Code Review
This pull request aims to fix an issue where the live block view was not updating. The change involves clearing the live monitor's cache on every refresh cycle. While this likely resolves the immediate problem, it introduces a significant performance regression by disabling the incremental data loading mechanism. My review focuses on this performance concern and recommends addressing the root cause of the update issue instead.

Calling monitor.clearCache() on every iteration of the monitoring loop defeats the purpose of the LiveMonitor class, which is designed for efficient, incremental data loading.
As per its implementation in src/_live-monitor.ts, LiveMonitor caches file timestamps and processed entries to avoid re-reading and re-processing all usage data on every refresh. By clearing the cache, you are forcing a full reload of all data files on every cycle. This can lead to significant performance issues, especially with a large amount of historical usage data, due to unnecessary file I/O and JSON parsing.
While this might fix the issue of usage not updating, it's a brute-force solution. The root cause is likely a bug in the incremental loading logic within LiveMonitor.getActiveBlock() that prevents it from detecting new or updated usage entries correctly. It would be better to investigate and fix that underlying issue rather than disabling the caching mechanism.
I recommend removing this line and debugging the incremental update logic.

Ok so let's try it and see the result. |

Yes. I have tested it and its working fine. However, the logic can be improved |
