## What's changed? Resolving the issue where `Monitor Historical Chart Detail` gets stuck during parsing and causes CPU utilization to max out when dealing with a large number of metrics. <img width="1508" height="862" alt="monitor_error" src="https://github.com/user-attachments/assets/c02af63e-c9a5-4937-a6cf-9dfdf623bdb1"; /> <img width="1476" height="753" alt="cpu_error" src="https://github.com/user-attachments/assets/f4acb568-2321-4d7a-9a68-a338588e6a7d"; /> **Cause of the issue:** When monitoring metrics contain large volumes of data, the front-end worker enters an infinite loop while assigning random colors to each curve. It attempts to find unused colors, but the color pool has been exhausted. **Fix Details:** Added a default retry limit (3 attempts) to the color allocation loop. If no unused colors are found, existing colors will be reused to prevent workers from getting stuck. <img width="1508" height="816" alt="success" src="https://github.com/user-attachments/assets/1a723e31-9f69-4588-9588-794de730a409"; /> ## Checklist - [x] I have read the [Contributing Guide](https://hertzbeat.apache.org/docs/community/code_style_and_quality_guide) - [ ] I have written the necessary doc or comment. - [ ] I have added the necessary unit tests and all cases have passed. ## Add or update API - [ ] I have added the necessary [e2e tests](https://github.com/apache/hertzbeat/tree/master/e2e) and all cases have passed. -- This is an automated message from the Apache Git Service.
