Re: [HTCondor-users] How to obtain condor slots historical usage information

Hi Gagan,

The machine ad which represents slots does record some ad attributes such as TotalTimeClaimedIdle, TotalTimeClaimedBusy, etc, but these attribute values are for the entire lifetime of the slot and not really in fragments of time. However, you could always set up a system to record this information in specified time intervals. You could do this by setting up a monitoring system like Ganglia with the condor supported Gangliad Daemon. Or you could query the Startd with condor_status in a script, a startd cron, or a manually every so often and record the output to create that over time data points.

Here are some links to various parts of our documentation that may be useful:

Hi Guys,

                 We need to decide how many  more condor executor nodes we need to add to our HT condor cluster. 

For that we first need to know the time period our cluster remains idle. When slots are free. 

So, please let me know how I can get this information.

 Like the time duration  slots in the cluster were busy or idle in  the last 24 hrs / 48 hrs or last week , etc. 

Thanks,

Gagan
