[Condor-users] [Birdbath Specific] Update Interval

[Afrasyab Bashir <afrasyab@xxxxxxxxx>]

Hi,

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.

Query:

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?

Thanks
Afras
