SNMP traps not received from Environmental Monitor

[Bill Gushue]

Another office has installed a WallBotz 500 (http://www.netbotz.com) and has configured snmp alerts to be sent to my HP SIM 5.0 server. I have performed a manual discovery and all seems well, except I don't seem to be receiving any traps?

1. After sending a test trap (from any system, for that matter), is there a log on the HP SIM server that will tell me the trap has been received.

2. Is there anything special I have to do to get alerts sent from this environmental monitor to work with HP SIM?

Thanks.

Have you registered a MIB for the device? Without a MIB, HP SIM will disregard the traps. You can confirm receipt of them (without translation) by enabling 'Accept unregistered traps' in Options --> Events.

[Bill Gushue]

No, I haven't registered a MIB for the device, basically 'cause I didn't know how. I'm looking at some help documents now. Is the MIB I have to register located in SIM, or is this something I have to get from the Device vendor somewhere?

Also, I enabled 'Accept unregistered traps' and sent a test and I did indeed receive the alert (via Email also - good). Now, does this mean I'll get other alerts from this device, or do I still have to register a MIB (which, I assume, I'd want to do anyway).

Thanks for the speedy reply!

[Bill Gushue]

Okay, I think I have something. I found a MIB file on the NetBotz download site. I want to make sure I know what I'm doing before I try this.

First, the mib file was an html page, so I "saved as" to a text file. The name of the file is netbotzv2_mib.txt (I added the .txt extension). It's attached.

Now, what should the name of the file be - netbotzv2.mib? Or does it even matter as long as there is a .mib extension?

Next, if I read the instructions correctly, I run "mcompile netbotzv2.mib". Does this then create a cfg file?

I then run "mxmib -a netbotzv2.cfg" - assuming it is created by mcompile.

Do I have this correct? Is there any way of possibly damaging the database, or if this doesn't work, I can just unregister it?

Thank you very much.

The worst that seems to happen is that you cannot register them.
Not all MIB formats seem to compile. The fact it's a two stage process tends to protect the database.

[Bill Gushue]

Well, I knew it would be too easy. I ran mcompile and received the following error:

Line: 28: Error defining registration: Invalid parent label or subid
Mib compilation failed.

Here's line 28:

::= { enterprises 5528 100 1 }

...and here's some lines around it, if it helps:

DESCRIPTION
"NetBotz BotzWare V2.x MIB"
REVISION "200509260000Z" -- 26 September 2005
DESCRIPTION "Added index columns"
::= { enterprises 5528 100 1 }

netBotz OBJECT IDENTIFIER ::= { enterprises 5528 }
netBotzV2 OBJECT IDENTIFIER ::= { netBotz 100 }

Any ideas on what the problem might be, or how I can fix it? Can I simply remark this entire "Description?" Sorry, but I don't know enough about mib files.

Thanks again.

Hi Bill,

This doc may be of some help, at least with the compiling and importing of mibs for SIM.

[Bill Gushue]

Thank you, I'll look at it. Dumb question, though - does HP SIM 5.0 support snmp v2? I assume it would, but...

[Rob Buxton]

You should be able to compile v2 mibs into HPSIM. Well the docs say you can.

[Bill Gushue]

Yes, I read the doc and of course it answered most of the questions I've already asked - sorry 'bout that.

Anyway, I compared some mibs with this one and I decided to delete the whole section, but then it errored on another line (1844). So I decided to simply remark out line 1844 and then it stopped at 1867, which I remarked out and it stopped again at another line. So you can obviously see where this is going, as this is a large mib. Not to mention that the lines I'm removing are all related to temperature alerts, which is exactly what the admin who runs this wants to monitor.

Each time I get the same "Invalid parent labelor sub id" error. I don't know what the "parent label" refers to.

I'm gonna try to get some help from the vendor itself.
