I am working on a patch for snmp_monitor.tcl to add a "Port Load" entry
to the menu. This has proven to be difficult, even though I have
concentrated on 3Com HUBs only. Different versions of management modules
implement different MIBs, or even parts of a MIB :-(
The only variable I have found outside dedicated 3Com MIBs are
rptrMonitorPortReadableOctets and that family from SNMP-REPEATER-MIB in
/pack/scotty-2.1.5/lib/tnm2.1.5/mibs/rfc1516.mib
If no MIBs are available for your HUb specifically, you might try this
variable.
It looks like the ifInOctets/ifOutOctets variables used in "Interface
Load" show traffic to the management module only :-(
If I am happy enough with the result of my work on "Port Load", I will
make the patch available through this list. My plan is to be able to
watch traffic on a port, having the %-load text below, and the name of the
host too, if I am able to find out who is there, by checking the
rptrAddrTrackLastSourceAddress variable every time. I try to change the
color of the graph depending on if the port is connected or not. So far
it works, but I have some fine-tuning to do. There are years since I did
tcl-programming :-\
If someone knows of a MIB that is implemented by most companies, that can
show the load of a HUB port, I would be very interrested to hear of it. I
would like my work to be useable on other than 3Com HUBs, but those are
the only ones I have to test on.
