Re: [HTCondor-devel] Need for dynamic slots in top-level collector?

No, no current way to reset stats without a daemon restart.   I've been thinking about ways to add a reset. 

What do you think about a knob.  RESET_DC_STATS_ON_RECONFIG.    There are multiple stats collections, so having that knob reset ALL of the stats would take some work.  But just resetting the DC stats and collector stats would be easy.

Yeah - but you can safely ignore all those "maximum" statistics.  The machine was heavily swapping, meaning all sorts of hell was breaking loose.

Is there a way to clear the statistics counters without restarting the process?

The child knows how long it spent, and that info goes into the log, but the top level collector is only recording how long it spent forking the child.
