[BUG] Writer metrics are filling up the disk #61
Description
What is the bug?
Writer metrics are filling up the disk. Currently, the cleanup method deletes the writer files (https://github.com/opensearch-project/performance-analyzer/blob/main/src/main/java/org/opensearch/performanceanalyzer/writer/EventLogQueueProcessor.java#L190)
This method deletes files up to the current time, but the file creation happens after this. Thus one file is left out during the file deletion. This cause accumulation of writer files.
What is the expected behavior?
Old writer files in the /dev/shm/performanceanalyzer should be deleted. Files older than 120 seconds should not be present.
What is your host/environment?
- OS: [e.g. iOS]
- Version [e.g. 22]
- Plugins
