[Condor-users] [Birdbath Specific] Update Interval


Case: I want to decide myself which all machines should execute my job. I want to base my decision upon certain information: for e.g. load, swap, memory, non-condor load etc. I believe I can decide well if I know how old that information is. In order to know the currency of information I should know at what interval this information is updated i.e. i should know the update interval.


Could you please guide me how to check the update interval of any condor pool using Birdbath?? i.e. using 'birdbath only' how to check that after what interval the updates are sent?

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can be outdated.

First off, some terminology: when you say 'the master', you really mean
'the central manager' (or, more accurately, the collector)

And to answer your question, yes, information you get from the
collector will be outdated. The update interval controls how
out of date your updates might be. Make the update interval smaller,
and the collector will be more up-to-date.

To get the most up-to-date information about a resource, use
condor_status -direct machinename.some.domain
