[Nagiosplug-devel] check_mrtg and check_mrtgtraf return incorrectly using versions from nagios 1.4.13

[Craig Braithwaite]

(I hope gmail really does send plain text when I ask it to.)

So.. Dear mailing_list
I've been struggling with these for a fortnight or so, and have tried
to learn enough about c to sort it out myself,
however I am so far failing.

check_mrtg apparently fails to return an OK status at any stage and is
initialised at UNKNOWN so therefore
continues to show unknown unless the values cause a flip to warning or
critical.

check_mrtgtraf also passes (or fails to?) something incorrectly to
nagios, as the command line usage can
be made to return a string of OK, however nagios reports warning for
the same values so is either
getting an incorrect return code, or none.

..At least, this is what I think. I've lived in the click-n-close
windows world too long and have never written
much more than 'hello world'.  From what I can gather these two
plugins will comprise a hefty proportion
of my monitoring options and the versions I have are (I think) the
most recent. (both report 1.4.13 but also1991)
I am new to everything related to this project,
. .linux (centos5.2 on a VM), nagios (3.0.6), mrtg (last months version)
so if I'm totally in the wrong place can someone point me in the right
direction.



Am I right, do these need updating?
If so, is it likely that someone reading this mailing list can do so
and inform us?
