This doesn't work. Was wondering if there is an easier or more intuitiveÂway to manage this

Hi Rita,

You don't say above if you are setting up a hold policy in your job submit file, or in your condor_config (to be applied to all jobs on the access point).ÂÂÂ I will assume the latter.

Yes, there is an easier way assuming you are running HTCondor version 9.5 or above, which is to use SYSTEM_PERIODIC_HOLD_NAMES and friends.ÂÂ See https://htcondor.readthedocs.io/en/latest/admin-manual/configuration-macros.html#SYSTEM_PERIODIC_HOLD_NAMES

This way, you can have separate hold reasons for each policy instead of globbing them all into one _expression_. Plus it is easier to add/remove policies without impacting others. Example from a condor_config file:

# Add a policy for memory
SYSTEM_PERIODIC_HOLD_NAMES = $(SYSTEM_PERIODIC_HOLD_NAMES) Mem
SYSTEM_PERIODIC_HOLD_Mem = MemoryUsage > XXXX
SYSTEM_PERIODIC_HOLD_Mem_REASON = "Memory usage exceeded XXXX"

# Add a policy for disk
SYSTEM_PERIODIC_HOLD_NAMES = $(SYSTEM_PERIODIC_HOLD_NAMES) Disk
SYSTEM_PERIODIC_HOLD_Disk = DiskUsage > YYYY
SYSTEM_PERIODIC_HOLD_Disk_REASON = "Disk usage exceeded YYYY"

Hope the above helps,
Todd
