See below for an old message with great guidlines..
..I have confirmed everything that Mike says below. I have identified all interfaces, selected one I know to be 'up' and checked it with the snmp tool in WUP, Net tools. Great! I get a resturned value of:
ifOperStatus.5=1
But when I view the debug log when I run 'poll' the custom service I get:
ping X returned in 13 ms. 0
Checking SNMP 1.3.6.1.2.1.2.2.1.8.5 on X
CHECK UDP 161 on X
<<< EXIT 10004
<<< EXIT 10004CHECK UDP 161 on X
failed!
I have also checked access control lists for port 161; I'm told they are open.
Please advise as this would be the icing on the cake if I could get this feature to work...
Many Thanks

Hello,
Step 1: Confirm the interface you want to monitor by taking a look at the
following mibs:
.1.3.6.1.2.1.2.2.1.2 ifDescr
.1.3.6.1.2.1.2.2.1.3 ifType
.1.3.6.1.2.1.2.2.1.5 ifSpeed
By browsing the above mibs, you should be able to figure out which instance
to monitor. You have probably already done this.
Step 2: Decide if you want to monitor incoming or outgoing traffic. We'll
use IfInOctets as you mentioned below.
.1.3.6.1.2.1.2.2.1.10 represents IfInOctets
.1.3.6.1.2.1.2.2.1.10.5 the .5 represents the interface we want to monitor
Step 3: Do the math. Lets say you want to be notified if traffic averages
over 1 megabit/sec for "the polling interval".
1000000 = 1 million bits/sec
1000000/8 = 125000 octets/sec
We should be using octets as this is what most devices I have run into use
as a counter.
Step 4: Create the service and give it a decent name (e.g. IfInOctets-5)
where -5 is the interface (i.e instance).
Step 5: fill in the blanks:
Object ID: 1.3.6.1.2.1.2.2.1.10.5
Check it for: Rate of Change in Value ;as we are looking for a delta
Rate of Change: 125000 ;octets in 1megabit/sec
Failing rate is: above ;traffic over 1 megabits on average in a polling
interval
Test fails when exceeded: 2 ;must occur in two polling intervals prior to
notification
Step 6: apply the service to the icon
If someone has some tips for me, I would appreciate it.
I hope that helps.

I don't know if anyone has clearly outlined this solution yet. I have
searched and searched both the list archive and the IPswitch knowledge base
and can come up with no definitive answers.
I am trying to achieve a threshold monitor on my 3 fractional T1's in a
Cisco. I am at a loss as to how to do this. Please can someone help me with
links or a procedure?
I have looked at IfInOctets and just cannot figure out how I would alarm on
such an esoteric number....
Help!
Craig.
