Query regarding Idle time for a machine

[Ram Ban]

Hi all,

Currently I am using NO_CLAIM_SHUTDOWN feature to stop machines which are not being used. Is there any way I can find the time of a machine which is not being used, for e.g. I have set NO_CLAIM_SHUTDOWN as 200 sec and now machine is not being utilised for 10 secs, I want to get this 10sec or may be 190sec(200-10) under any field of condor_status, Is there any way to get this?

I am currently using partition able slots for all machines and htcondor 25.0.7 version

Thanks and Regards 

Raman

Each p-slot has two attributes by default 

NumDynamicSlots

NumDynamicSlotsTime

The first is the number of dynamic slots under that p-slot.  when that number is 0, then there are no claimed slots, which means the p-slot is idle.  If that is the only p-slot on the Startd,  then the whole Startd is idle. 

NumDynamicSlotsTime is the unix timestamp of the time when NumDynamicSlots changed,  so when NumDynamicSlots is 0, then that is the time when the Startd became idle. 

So something like this

    condor_status -const PartitionableSlot -af Machine 'IfThenElse(NumDynamicSlots, 0, (time() - NumDynamicSlotsTime))'

Will print the machine name followed by how many seconds it has been idle.
