RE: How can I test or simulate an SNMP trap?

The easier way is just to enable the snmp traps (with 'snmp traps enable' and 'snmp init 1'). This will cause all the factory set traps (like fan failures, disk failures, power supply, temp etc.) to be enabled automatically. (The list is in the MIB, at the end, titled "NetApp trap definitions", on MIB versions 1.5 and up) Alex. -----Original Message----- From: markallen [mailto:markallen@micron.com] Sent: Wednesday, July 10, 2002 16:53 To: 'Drew O'Donnell'; toasters(a)mathworks.com Subject: RE: How can I test or simulate an SNMP trap? Drew, I went into filerview and created a snmp trap for a failed fan. I new what the normal values were and I knew what the abnormal values were. I found out this information by viewing the two files found in /etc/mib. I inverted the values in the SNMP trap by using a normal value to send the trap on. Once it sent the traps and I was finished testing I changed the trip value back to normal so I'm watching for a failed fan or cpu. For example if the normal state of a fan is value=0 and the failed state value=1 I changed the trip value for testing purposes to 0 and then once the testing was over I changed it back to watch for 1.

You should receive a "STATUS: Normal" message (at least I hope normal is the status on you system) every round hour. The system sends it when at the same time it writes the message to the console. If it doesn't try the following: Snmp traps enable Snmp init 1 This should generate a bunch of messages also if snmp was not initialized. You can also run 'snmp init 0' and then 'snmp init 1' and see what happen.

Strikes me that that *is* failing the hardware hisself.

Mark (or anyone on Toasters), Where do you configure the "trip value"? Also, I have a normal trap setup to go to my SNMP host, but I am not getting alerts, especially when we have QTREES set up to alert us when a QTREE gets to 90%. I have had some QTREES exceed 90% and never was alerted.

I have had several responses from within NetApp, all saying much the same thing. Steven Yee specifically requested that I publish his response here, so I will do that: | I would appreciate if you would repost this to toasters for me. | | NetApp Employees (well, engineering at least ;) still read toasters, | and often privately reply as appropriate.

I understand the necessity to close the list in a hurry due to the spam situation, but problems like the above ought to have been ironed out by now. Most list management software I am aware of allows for the set of permitted posters and the (direct) list recipients to be different. Would fubar care to comment?
