Snmp Oids

[Tomer Ratz]

Hi

My monitoring system (IPSwitch What's up Gold) is set up not to receive SNMP TRAPS from anybody, meaning I have to define each trap specifically (otherwise I'll be over-swamped with traps).

When I want to define the trap manually I need to supply an OID, or at least the beginning of the OID which I suppose it common to all of Monyog's traps.

What is it then?

I read the MIB file, but it doesn't specify the OIDs.

Thank you in advance,

Tomer.

Hey Tomer,

Here's the private enterprise OID for Webyog:

.1.3.6.1.4.1.34330

MONyog is defined under Webyog:

.1.3.6.1.4.1.34330.1

All objects sent in SNMP traps by MONyog (including the traps, themselves) are defined under this OID tree.

It's all very standard, actually. You could have easily discovered this from the MIB file. Here's how:

— The .iso.org.dod.internet.private.enterprises tree, by standard, should contain all private enterprise numbers (PEN); this translates to .1.3.6.1.4.1

Code:

IMPORTS
enterprises
FROM SNMPv2-SMI;

— Webyog's PEN as assigned by IANA is 34330 (this is mentioned in the MIB file); append that to .iso.org.dod.internet.private.enterprises, and you get the complete OID for Webyog.

Code:

webyog OBJECT IDENTIFIER ::= { enterprises 34330 } — Note: As assigned by IANA (http://www.iana.org/)
monyog OBJECT IDENTIFIER ::= { webyog 1 }

Hope that clears the concept of private enterprise OIDs for you!

Thanks for your interest in MONyog!

The SNMP Trap looks like this:

monitorTrap

enterprises.34330.1-1

TrapName=enterprises.34330.1-1 TrapMajor=6 TrapMinor=1 enterprises.34330.1.1.1.0=Pooh Cluster enterprises.34330.1.1.2.0=All Time/Current CommunityName=public enterprises.34330.1.1.3.0=Critical enterprises.34330.1.1.4.0=Current Connections 1.3.6.1.4.1.34330.1.1.1.0=Pooh Cluster enterprises.34330.1.1.5.0=Percentage of max allowed reached 1.3.6.1.4.1.34330.1.1.2.0=All Time/Current Packet Type=Trap enterprises.34330.1.1.6.0=52.57% 1.3.6.1.4.1.34330.1.1.3.0=Critical enterprises.34330.1.1.7.0=50 1.3.6.1.4.1.34330.1.1.4.0=Current Connections Protocol Version=SNMPv1 enterprises.34330.1.1.8.0=1. Make sure that you have a reasonable high value for max_connections.

3. Try pooling connections or switch to persistent connections to reduce the number of active MySQL connections. For example try using mysql_pconnect() instead of mysql_connect() 1.3.6.1.4.1.34330.1.1.5.0=Percentage of

Is there anyway to “strip” all the unnecessary information from it (e.g. enterprises.34330.1.1.1.0=Pooh Cluster enterprises.34330.1.1.2.0=All Time/Current CommunityName=public)?

As you can see the trap is very scrambled at the moment.

That would entirely depend on the SNMP client software that you are using. For example, here's a screenshot of how traps appear in the lightweight receiver from iReasoning:

I suspect that there should be a way to load MIB files from your SNMP client. That way, you wouldn't even have to add the OIDs manually, and much of the gibberish numbers are actually converted into much more meaningful strings.

For instance, on iReasoning's MIB Browser, enterprises.34330.1.1.1.0 appears as enterprises.webyog.monyog.monitor.ServerName.0

Which SNMP client are you using, anyhow? Maybe I can play around with it a bit, and then I can give some pointers.

Thanks!

I'm using IPSwitch's What's Up Gold.

I've loaded the MIB file which comes with MONyog directly into the software.
