C.4.2. General::Remote Program with Data

The General::Remote Program with Data probe allows you to run any command or script on your system and obtain a value, as well as a status string. To use this probe, you must include XML code in the body of your script. This probe supports the following XML tags:

The remote program will need to output some iteration of the following code to STDOUT:

<perldata> 
  <hash> 
    <item key="data">10</item> 
    <item key="status_message">status message here</item> 
  </hash> 
</perldata>

The required value for data is the data point to be inserted in the database for time-series trending. The status_message is optional and can be whatever text string is desired with a maximum length of 1024 bytes. Remote programs that do not include a status_message still report the value and status returned.

Requirements — The Red Hat Network Monitoring Daemon (rhnmd) must be running on the monitored system to execute this probe. XML is case-sensitive. The data item key name cannot be changed and it must collect a number as its value.
