Hello Leonardo,

The syntax you're using with the '-w' and '-c' options is wrong. From
the manual page:

       -w, --warning STRING or FILE
           Override the machine-default temperature warning
           thresholds. Syntax is "id1=max[/min],id2=max[/min],...". The
           following example sets warning limits to max 50C for probe 0,
           and max 45C and min 10C for probe 1:

           check_openmanage -w 0=50,1=45/10

           The minimum limit can be omitted, if desired. Most often, you
           are only interested in setting the maximum thresholds.

           This parameter can be either a string with the limits, or a
           file containing the limits string. The option can be
           specified multiple times.

           NOTE: This option should only be used to narrow the field of
           OK temperatures wrt. the OMSA defaults. To expand the field
           of OK temperatures, increase the OMSA thresholds. See the
           plugin web page for more information.

       -c, --critical STRING or FILE
           Override the machine-default temperature critical
           thresholds. Syntax and behaviour is the same as for warning
           thresholds described above.

The reason that you need to specify the ID of the temperature probes is
that there may be more than one, each with its own thresholds. In your
case there is only one probe and its ID is 0, so replace your command
above with:

  check_openmanage -w 0=25 -c 0=30 -H 10.11.12.1 -C Test --only temp

That should do the trick.
