[Condor-devel] Condor statistics: How is "LastAvailInterval" calculated?

[Rob <spamrefuse@xxxxxxxxx>]

Hello,

I have "STARTD_COMPUTE_AVAIL_STATS = True" on my condor pool PCs.

On the master, I collect this information every 5 minutes with a periodic
script and using the condor_status command.


I typically get the following:

# LastAvailInterval EnteredCurrentState State
0 1263173736 Owner
0 1263175546 Unclaimed
900 1263176446 Owner
900 1263177346 Unclaimed
300 1263177646 Owner
300 1263179146 Unclaimed
1200 1263180346 Owner
1200 1263181246 Unclaimed
2400 1263183646 Owner
2400 1263186646 Unclaimed
8105 1263194751 Owner
8105 1263196252 Unclaimed
2100 1263198352 Owner


The first number in the lines with "Owner" is the length (in seconds)
of the previous "Unclaimed" (i.e. idle) interval.

It surprises me that the first numbers on each line are such nicely
rounded-off numbers.....

A pool PC is supposed to switch to Owner state immediately when a user
touches the keyboard or mouse....which is a rather random event.
Then why are the idle intervals such nicely rounded numbers?

Can somebody explain this to me?

Thank you!

Rob.
