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:
| Option | Description |
|---|---|
--help
|
List the available options and exit. |
--probe=
|
Run the probe with this ID. |
--prob_arg=
|
Override any probe parameters from the database. |
--module=
|
Package name of alternate code to run. |
--log=all=
|
Set log level for a package or package prefix. |
--debug=
|
Set numeric debugging level. |
--live
|
Execute the probe, enqueue data and send out notifications (if needed). |
Table 7.1. rhn-runprobe Options
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.
