7.6.2. Viewing the output of rhn-runprobe

Now that you have obtained the probe ID with rhn-catalog, use it in conjunction with rhn-runprobe to examine the complete output of the probe. Note that by default, rhn-runprobe works in test mode, meaning no results are entered in the database. Here are its options:

Table 7.1. rhn-runprobe Options

Option Description
--help List the available options and exit.
--probe=PROBE_ID Run the probe with this ID.
--prob_arg=PARAMETER Override any probe parameters from the database.
--module=PERL_MODULE Package name of alternate code to run.
--log=all=LEVEL Set log level for a package or package prefix.
--debug=LEVEL Set numeric debugging level.
--live Execute the probe, enqueue data and send out notifications (if needed).
At a minimum, you should include the --probe option, the --log option, and values for each. The --probe option takes the probeID as its value and the --log option takes the value "all" (for all run levels) and a numeric verbosity level as its values. Here is an example:
rhn-runprobe --probe=5 --log=all=4 
The above command requests the probe output for probeID 5, for all run levels, with a high level of verbosity.
More specifically, you may provide the command parameters derived from rhn-catalog, like so:
rhn-runprobe 5 --log=all=4 --sshuser=nocpulse --sshport=4545 
This yields verbose output depicting the probe's attempted execution. Errors are clearly identified.
