condor_top

Display status and runtime statistics of a HTCondor daemon

Synopsis

condor_top [-h]

condor_top [-p centralmanagerhostname[:portname]] [-n name] [-d delay] [-s sortcolumn] [--attrs=$<$attr1,attr2,...$>$] [daemon options]

Description

condor_top displays the status (CPU time and memory usage) of and calculates and displays runtime statistics for a HTCondor daemon. condor_top uses consecutive ClassAds to compute average runtimes and counts of the various commands worked on by the daemon. In the case that a condor_collector is queried, the duty cycle and operations per second are also displayed.

When no arguments are specified, condor_top displays the condor_collector status from COLLECTOR_HOST. If the condor_collector on COLLECTOR_HOST returns multiple ClassAds, condor_top displays stats from the first ClassAd returned.

The default delay is STATISTICS_WINDOW_QUANTUM, which is 4 minutes (240 seconds) in a default HTCondor configuration. Setting the delay smaller can be helpful for finding spikes of activity, but setting the delay too small will lead to inaccurate measurements of the condor_collector duty cycle and of command counting rates.

To exit condor_top, issue Ctrl-C.

Options

-h
Displays the list of options.
-p centralmanagerhostname[:portname]
Query the daemon via the specified central manager. If omitted, the value of the configuration variable COLLECTOR_HOST is used.
-n name
Query the daemon named name. If omitted, the value used will depend on the type of daemon queried (see Daemon Options). If the named daemon returns multiple ClassAds, the first ClassAd returned will be monitored.
-d delay
Specifies the delay between ClassAd updates, in integer seconds. If omitted, the value of the configuration variable STATISTICS_WINDOW_QUANTUM is used.
-s sortcolumn
Sort table by sortcolumn. Available columns: Runtime (default), InstAvg, Avg, CountRate, Count, Max, Item
--attrs=$<$attr1,attr2,...$>$
Comma-delimited list of additional ClassAd attributes to monitor.

Daemon Options

--collector
Monitor condor_collector ClassAds. If -n is not set, COLLECTOR_HOST will be queried.
--master
Monitor condor_master ClassAds. If -n is not set, COLLECTOR_HOST will be queried.
--negotiator
Monitor condor_negotiator ClassAds. If -n is not set, COLLECTOR_HOST will be queried.
--schedd
Monitor condor_schedd ClassAds. If -n is not set, FULL_HOSTNAME will be queried.
--startd
Monitor condor_startd ClassAds. If -n is not set, slot1@FULL_HOSTNAME will be queried.
