As I understand them, the multiple values should be read "Try these in order *until* you find one that works", rather than "Try them all" as it sounds like you want.

This sounds like a wonky SNMP implementation, so you might need some tweaking as I don't think the standard SNMP modelers are going to do what you need.

My guess is that the only way you'll get this working is to write a custom modeler, and or/or custom command data source so you can run a bash script to gather the data you need. Its really  shame you can't just access everything using a single SNMP community string, like most devices

As I understand each modem has it's own ip address? Why not to add modems to zenoss as seprate devices using specific communities?

If you are just trying to do SNMP graphing of modem OIDs, you can use a simple command data source script to run an snmpget, append the .1 .2 .3 .4 to the community name string, and then you will have graphing working.

The following would work as a simple command template for modem 1 (you can copy and paste this directly into the command template box when you add a new data source:

/bin/echo "SNMP Status OK|modem1OidIWant=$(snmpget -${dev/zSnmpVer} -c ${dev/zSnmpCommunity}.1 -OUvq ${dev/manageIp} 1.3.6.1.4.1.10854.10.8.4)"

Replace the oid number above with the oid you want to graph. The -c ${dev/zSnmpCommunity}.1  should call the command with -c public.1 which would work for modem 1

Then you add a data point called "modem1OidIWant" and graph that.. you should get the value.

Hi, you have to make a new data source of type "COMMAND", not type "SNMP". When you do so, there will not be an OID prompt, instead there will be a "command template" box. That is where you want to copy and paste the line.

Hi, I'm sorry that my instructions were not more clear..

After you add the data source you have to add one or more data points.. if you don't have the data point there is nothing to add to a graph.

The data point gets added inside the data source.. with the command data source selected, use the menu above to choose "add data point" and add a new data point. Make sure it uses the same name as you specified in the command data source string (in my example this was 'modem1OidIWant').

Hi, I see the issue.. the command template has in it "modem2OidIWant" but the data point does not have the letter "I" (uppercase i). If you don't want the 'I', remove it from the command template so that it starts with /bin/echo "SNMP Status OK|modem2OidWant=$( etc....
