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:
•
<
perldata
> <
/perldata
>
•
<
hash
> <
/hash
>
•
<
item key =" "
> <
/item
>
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.
