Monitoring HTCondor

Andrew Lahiff

STFC Rutherford Appleton Laboratory

European HTCondor Site Admins Meeting 2014

Introduction• Two aspects of monitoring

– General overview of the system• How many running/idle jobs?

By user/VO? By schedd?

• How full is the farm?

• How many draining worker nodes?

– More detailed views• What are individual jobs doing?

• What’s happening on individual worker nodes?

• Health of the different components of the HTCondor pool

• ...in addition to Nagios

Introduction• Methods

– Command line utilities

– Ganglia

– Third-party applications(which run command-line tools or use python API)

Command line• Three useful commands

– condor_status• Overview of the pool (including jobs, machines)• Information about specific worker nodes

– condor_q• Information about jobs in the queue

– condor_history• Information about completed jobs

Overview of jobs-bash-4.1$ condor_status -collector

Ganglia• condor_gangliad

– Runs on a single host (can be any host)

– Gathers daemon ClassAds from the collector

– Publishes metrics to ganglia with host spoofing

• At RAL we have on one hostGANGLIAD_VERBOSITY = 2

GANGLIAD_PER_EXECUTE_NODE_METRICS = FalseGANGLIAD = $(LIBEXEC)/condor_gangliadGANGLIA_CONFIG = /etc/gmond.confGANGLIAD_METRICS_CONFIG_DIR = /etc/condor/ganglia.dGANGLIA_SEND_DATA_FOR_ALL_HOSTS = trueDAEMON_LIST = MASTER, GANGLIAD

Ganglia• Small subset from schedd

Ganglia• Small subset from central manager

Easy to make custom plots

Total running, idle, held jobs• f

Running jobs by schedd

Negotiator health• s

Negotiation cycle duration Number of AutoClusters

Draining & multi-core slots

Mimic• Internal RAL application

htcondor-sysview

htcondor-sysview• Hover mouse over a core to get job information

Nagios• Most (all?) sites probably use Nagios or an alternative• At RAL

– Process checks for condor_master on all nodes– Central mangers

• Check for at least 1 collector• Check for the negotiator• Check for worker nodes

Number of startd ClassAds needs to be above a threshold

Number of non-broken worker nodes above a threshold

– CEs• Check for schedd• Job submission test
