condor_dagman_metrics_reporter

Report the statistics of a DAGMan run to a central HTTP server

Synopsis

condor_dagman_metrics_reporter [-s] [-u URL] [-t maxtime] -f /path/to/metrics/file

Description

condor_dagman_metrics_reporter anonymously reports metrics from a DAGMan workflow to a central server. The reporting of workflow metrics is only enabled for DAGMan workflows run under Pegasus; metrics reporting has been requested by Pegasus’ funding sources: see http://pegasus.isi.edu/wms/docs/latest/funding_citing_usage.php#usage_statistics and https://confluence.pegasus.isi.edu/display/pegasus/DAGMan+Metrics+Reporting for the requirements to collect this data.

The data sent to the server is in JSON format. Here is an example of what is sent:

{
    "client":"condor_dagman",
    "version":"8.1.0",
    "planner":"/lfs1/devel/Pegasus/pegasus/bin/pegasus-plan",
    "planner_version":"4.3.0cvs",
    "type":"metrics",
    "wf_uuid":"htcondor-test-job_dagman_metrics-A-subdag",
    "root_wf_uuid":"htcondor-test-job_dagman_metrics-A",
    "start_time":1375313459.603,
    "end_time":1375313491.498,
    "duration":31.895,
    "exitcode":1,
    "dagman_id":"26",
    "parent_dagman_id":"11",
    "rescue_dag_number":0,
    "jobs":4,
    "jobs_failed":1,
    "jobs_succeeded":3,
    "dag_jobs":0,
    "dag_jobs_failed":0,
    "dag_jobs_succeeded":0,
    "total_jobs":4,
    "total_jobs_run":4,
    "total_job_time":0.000,
    "dag_status":2
}

Metrics are sent only if the condor_dagman process has PEGASUS_METRICS set to True in its environment, and the CONDOR_DEVELOPERS configuration variable does not have the value NONE.

Ordinarily, this program will be run by condor_dagman, and users do not need to interact with it. This program uses the following environment variables:

PEGASUS_USER_METRICS_DEFAULT_SERVER: The URL of the default server to which to send the data. It defaults to http://metrics.pegasus.isi.edu/metrics. It can be overridden at the command line with the -u option.
PEGASUS_USER_METRICS_SERVER: A comma separated list of URLs of servers that will receive the data, in addition to the default server.

The -f argument specifies the metrics file to be sent to the HTTP server.

Options

-s: Sleep for a random number of seconds between 1 and 10, before attempting to send data. This option is used to space out the reporting from any sub-DAGs when a DAG is removed.
-u URL: Overrides setting of the environment variable PEGASUS_USER_METRICS_DEFAULT_SERVER. This option is unused by condor_dagman; it is for testing by developers.
-t maxtime: A maximum time in seconds that defaults to 100 seconds, setting a limit on the amount of time this program will wait for communication from the server. A setting of zero will result in a single attempt per server. condor_dagman retrieves this value from the DAGMAN_PEGASUS_REPORT_TIMEOUT configuration variable.
-f metrics_file: The name of the file containing the metrics values to be reported.

Exit Status

condor_dagman_metrics_reporter will exit with a status value of 0 (zero) upon success, and it will exit with a value of 1 (one) upon failure.
