SNMP set up for Zenoss server

snmpzenoss

I've setup snmpv2 for communicating with Zenoss server. It's working.
But now I have some question.
1. Is SNMPv2 client broadcasting its data all the time? Is there any way to prevent that? Through configuration file? Can I use SNMP configuration file to limit it broadcast to certain ip only?
2. If I'm trying to push my snmp info to a server with dynamic ip, is it possible? How should it know the server? By domain name? Use SNMPv3? Anyone mind to guide me?

Short version: SNMP doesn't broadcast.

SNMP can mean two things. If you're talking about sending traps, then it sends it to a specific address that you would have to set up.

But normally what people are talking about is the box responding to a server asking for certain SNMP info. You can limit who can query this info in two ways:

By having a community string set (You can think of this as a password)
Limiting the IPs that can query.

Zenoss – One email alert for multiple events

Yes, Zenoss can do this using event mappings. Basically, you tell Zenoss to suppress events from certain "child" sources if a designated "parent" source also have active events.

There's a short explanation on the Zenoss community wiki, here:

http://community.zenoss.org/docs/DOC-3215.

A common example scenario is remotely monitoring a site with several monitored severs accessible only via a single gateway. If the gateway dies, the servers behind it will be unreachable, and Zenoss will generate events for unresponsive gateway and all of the servers. In this case, the gateway would be a "parent" of the server "children", and an unresponsive-gateway event will cause Zenoss to suppress the unresponsive-server events.
