[Condor-users] Update Interval Basics

[Afrasyab Bashir <afrasyab@xxxxxxxxx>]

Hi,

I will be most grateful if my this basic doubt about update interval is 
clarified. Please note that this query is not birdbath specific but relates 
to updating mechanism of condor.

Update interval by default is 5 minutes. This is the time after which all 
daemons update the master. I was wondering (and I read the manual to try to 
understand it but there wasn't much there) if a computer sends its memory 
update as 5666 available and after 3 minutes there is only 100 remains 
available and rest all is consumed by some processes. Now would condor 
choose the node upon this 5666 available memory or before deciding it will 
check all the nodes again (even when its not the right time of update as its 
only 3 minutes passed whereas the update interval is 5 minutes).

Now according to an earlier reply about polling interval it seems that an 
instance's daemons keep updating it quite frequently but they only update 
the master after 5 minutes (or whatever time is specified as update 
interval). So in the light of this i can understand that a particular 
instance will always know the changes that are taking place from time to 
time but it will only update the master when its the time according to 
update interval. It, if true, implies that before the update if condor is 
queried through birdbath about the load state, swap etc then the information 
can be outdated.

I will highly appreciate your comments.

Cheers
