Re: [Devmon] [hobbit] Graph/Devmon Help Needed

I think it is better to move this thread to the devmon list ...

Does it ship with any of the HPASM stuff running ? This would allow monitoring 
of RAID arrays, the IML log and a few other interesting bits and pieces.

You should look at the devmon logs. 

However, it may be best just to set the device type to linux-openwrt, e.g. by 
using something like this in your bb-hosts file:

xxx.xxx.xxx.xxx yyy # DEVMON:model(linux;openwrt)


You may also want to only run specific tests, and add one more test at a time, 
e..g:

xxx.xxx.xxx.xxx yyy # DEVMON:model(linux;openwrt),tests(disk)

The linux-openwrt template is a basic one that should work with any Linux 
system running net-snmp (it works fine against my desktop box), but only has a 
few tests enabled (as the net-snmp for OpenWRT is quite minimal).

The previous template, while it provided values, should really be using 
repeaters (the OIDs should all be of type branch) and a TABLE, otherwise it is 
going to be quite fragile ....
