Question by Jayne M. · Aug 25, 2015 at 10:15 PM ·

Can I delete collector cache for a 6.0.0 collector if we are on 6.2 but it was never properly migrated?

My (Linux) dynatrace filesystem is currently at 100% and I suspect it is interfering with the collector processing (error is "Skipping class cleanup because there isn't sufficient space available (2.31 GB required)"). The collector is running but no agents are connected.

Our environment was migrated to 6.2 in early July but the collectors were not migrated at that time due to space issues. I was not aware of this until the servers were rebooted (normally) about a month later and the collectors did not restart properly. They were restarted using the 6.2 files but never went through the migration process. Now I have instances of the same collector in both my 6.0.0 (~ 8GB) and 6.2 (~2.5GB) directories. Can I remove the 6.0.0 instance files without corrupting anything?

Hi Jayne

If I read this correctly you have the 6.2 running in a different directory - correct? And you no longer need or run the 6.0 instance? If that is the case it is very safe to delete the whole 6.0 directory including the 8GB class cache
