We have a shell script in order to expire files older than x days.
The idea is to move this to ChukwaAgent in order to reduce the number of daemon running and the overall complexity.
This could be done in a background/low priority Cleanup Thread inside the agent.
The input should be a configuration file with:
- path + fileName + regex (similar to the expiration in our Log4J appender)
- number of days (last accessed/modified? date)
The initial version could be as simple as this but a more advanced version will be needed.
The advanced version should be able to track data completeness based on CHUKWA-203 and only remove file that has been completely sent over or generate alerts.
