Rich Obrecht

Does anyone have a quick method for doing SNMP polling that’s documented?  If you do, can you forward it to me?  Honestly, the documentation on the OpenNMS site is pretty bleak…

snmpget?

(look at www.opennms.ORG and then "configuration", that should get you started)

I can do that - what I'm looking for is enabling polling within OpenNMS
on a consistent basis.  I want to gather SNMP stats, etc., for
graphing...

Have you told OpenNMS the community strings to use?

--> edit snmp-config.xml

Are your hosts configured?  

--> For example, by default Windows does not install SNMP.  Once it is
installed, Windows hosts do not have any SNMP community strings set up,
and limit access to localhost. So OpenNMS would not be able to pull SNMP
data.  Same deal with switches & routers.  Typically you have to set it
up in the configs.

Sorry if this seems like a "check the power plug" response, but SNMP
polling on a consistent basis is something OpenNMS does out of the box.

This 'just works' if the targets answer snmp requests with the community
string you are providing.  It is a little confusing that the node page
says snmp is not monitored but that is because it has its own separate
data collecting service.   Click the 'resource graphs' link on a node
page that you think should be responding to snmp queries - if you see IP
addresses there you may already have the graphs you want.

Yep, got the SNMP community set, and I also have SNMP turned on in all
the devices (routers/switches)...

You haven't told us anything about the kinds of hosts you'd like to  
manage, so there's not much to go on in terms of suggested next  
steps.  SNMP agents tend to be a little like oil filters: most people  
never personally touch them; some are easy to get to, some are a minor  
pain to get to, and some virtually guarantee a burnt forearm and  
skinned knuckles to anybody who goes near them.  In any case, you'll  
probably feel like washing your hands right after dealing with one :)

Terminology warning: you say "polling", but in OpenNMS terms you're  
talking about "data collection".

Once you have:
- Configured your SNMP agents
   - To answer for the correct community string
   - And the correct protocol version (usually v1 or v2c)
   - On the correct interface (i.e. not 127.0.0.1)
   - To requests from the IP address of your OpenNMS server
- And allowed the traffic through any firewalls in between

And you have configured OpenNMS:
- To use the same community string as your SNMP agents
- And the same protocol version as your SNMP agents
- And perhaps adjusted timeouts for some of your SNMP-enabled hosts

Data collection just starts happening.  As Les suggested, check out  
the "Resource Graphs" link from one of your nodes on which the SNMP  
service appears.  If you see a scrolling list for "Node-Level  
Performance Data" in that page, then you're already collecting SNMP  
data.

Importing data

In reply to this post by James Zuelow
I used the "export data" selection under import/export data to construct
a .CSV file, and have since populated it.  Upon attempting to import it,
however, I receive an error message that there are not enough
values...what am I doing wrong?

What kind of data are you talking about?  I can infer from context  
that you mean node asset data, is that right?

Is your editor (spreadsheet or whatever) stripping empty∆í columns from  
the end of lines?  The import process won't tolerate this kind of  
mangling.  Try comparing the original and updated CSV files, and check  
that the header line and some line that you did not modify have the  
same number of commas (excluding quoted ones) in both files.
