[Ovirt-devel] Limiting node writes...

Objective:
Reduce the amount of writing done to the managed node's filesystem.
Since the managed node is run on an in-memory file system, excessive
writes to such things as log files will eventually cause an
out-of-memory condition. Our goal is to limit the amount of writes.
Discussion:
Initially, rotating logs every hour and deleting all old logs is the
likely first pass.
A usable feature would be for the WUI to push down (during the identify
phase, maybe?) a threshold for when logs should be aggressively deleted.
Then the admin can decide to hold onto logs until disk space hits some
threshold and then start throwing away old logs. That way some history
can be viewed if needed.
In future, a more preferable solution would be to have the oVirt server
collect logging information for all managed nodes centrally. However,
this would need to use an encrypted pipe to send the data.
Thoughts?
