Re: [Devmon] Devmon-support Digest, Vol 38, Issue 6

[<mv...@so...>]

I've just installed devmon with some help from the list.  Take a look at the 
thread below - It may help you get some answers. 

Are you installing on a single or multi-node? 

I should be able to help you get the single node up and running. 

Regards,
Mario

 From http://sf.net/projects/devmon, click the support link, which takes you 
to
http://sourceforge.net/projects/devmon/support, which has a link to the
archives, which are at: 

http://sourceforge.net/mailarchive/forum.php?forum_id=6501

The graph definitions for if_load are missing (from hobbitgraph.cfg or
similar). Either append extras/devmon-graph.cfg to Xymon's hobbitgraph.cfg, 
or
make a directory in which to store additional graph configuration files 
(e.g.
etc/hobbitgraph.d), drop extras/devmon-graph.cfg, and specify "directory
/path/to/hobbitgraph.d" in hobbitgraph.cfg . 

I have also enabled the wiki on sourceforge, but haven't had much time to
populate it with content. I hope to do so in the near future.

If you were to shut the interface, it would stay green. Your network
administration policy (whether to shut unused ports or not) should determine
whether you should do this on a per-device basis, per-blade basis or 
per-port
basis (or a combination). 

E.g., I would typically not have exceptions on a router, on a data center
switch I might put non-critical devices on a specific blade, and not
necessarily shut unused ports.

When you complete this template, please log a ticket on the sourceforge
"patch" tracker, with category "Template", so I can review and include the
template in future.

Did the regex in the sysdesc line really match the sysdescr.0 value on the
device?

It may require at least one test ... I haven't checked, but will take a 
look.
