Re: [HTCondor-users] hibernating an idle machine ONLY after it has been up for X seconds

Hi Greg,

To put the system uptime into the machine classad you could add something like this to the condor config:

STARTD_CRON_JOBLIST = $(STARTD_CRON_JOBLIST) WN_UPTIME
STARTD_CRON_WN_UPTIME_EXECUTABLE = /usr/local/bin/condor_uptime
STARTD_CRON_WN_UPTIME_PERIOD = 5m
STARTD_CRON_WN_UPTIME_MODE = periodic
STARTD_CRON_WN_UPTIME_RECONFIG = false
STARTD_CRON_WN_UPTIME_KILL = true

where /usr/local/bin/condor_uptime contains:

#!/bin/sh
awk '{print "SystemUptime = " $1}' /proc/uptime

The attribute SystemUptime would then contain the system uptime.

Regards,
Andrew.

Thanks for your reply Ben

Forgive me if I miss understand. Aren’t those cases the same cases as using MonitorSelfAge? If the Daemon resets it works, but otherwise hibernates to quickly?

What would that look like? I currently have a script that passes the StartLog for signs of having woke up from Hibernation but I couldn’t find a way to “feed” that info into the config file.

Thanks
Greg
