Re: [HTCondor-users] Total load average using multiple partitionable slots

The compact mode output is not the sum of the individual slot loads,  in fact the compact mode query to the collector does not even get back the dynamic slot classads, so it can't sum what is in them.   The compact mode should be showing the total load on the machine, not just the total load of condor on the machine.

The LoadAvg of normal condor status is the value from the CondorLoadAvg of each slot.  As you can see, that value is 0 for the partitionable slot since no job ever runs there. 

The CpuLoad column of condor_status -compact is the TotalLoadAvg of the whole machine divided by the number of Cpus on the machine.  

Try running 

condor_status -const PartitionableSlot -af:h Name TotalLoadAvg/TotalCpus 

If you have multiple p-slots on the machine, I would expect them to all show the same values

Subject: [HTCondor-users] Total load average using multiple partitionable slots

I’m struggling to interpret the load average metrics on machines that are configured with multiple partitionable slots.

As an example, here is the output of a basic condor_status command

condor_status [machine]


Slot 1:


Slot 2:


We can see that all of the dynamic slots have an average CPU load close to 1, which I would expect. However, running this in compact form produces:



The CpuLoad doesn’t seem to correctly capture the total load summed across all dynamic slots. I’m wondering if this is a bug, or if there is another way I can capture total CPU load on a machine like this.
