Hi there! I understand that you’re facing some issues with Prometheus TSDB compactions. Compaction is an important process in Prometheus that helps reduce the size of data stored in the TSDB, and it’s crucial to keep your metrics database healthy.
When you encounter failed compactions, the first thing you should do is check the logs for any error messages or warnings that might give you a clue as to what went wrong. Common reasons for compaction failures include insufficient disk space, corrupted data blocks, or out-of-memory errors.
If disk space is the issue, you can try increasing the storage capacity of your system or deleting some old data to free up some space. If corrupted data blocks are causing issues, running a repair on your TSDB may help fix the problem.
It’s also worth checking if any recent changes were made to your configuration files or if any updates were installed recently. Sometimes these changes can have unintended consequences on the performance of your metrics database.
If all else fails, consider reaching out to the Prometheus community for support. They may be able to offer additional guidance or troubleshooting steps specific to your situation.
I hope this helps! Let me know if you have any further questions or concerns.
