NetXMS Support Forum

Hi!

It's nice to see that such solutions are possible with NetXMS I hope you'll describe this in wiki when it will be working.

I would optimize this a bit by using nxevent instead of nxpush on step 3 and just calling script from library on some custom event. Also, if writing some Java code is an option, you can create simple class that will set custom attributes directly using NetXMS Java API. Otherwise solution looks good.

You should have AP name as an instance. You can create some attribute, like isDown, and set it to true on down trap and to false on up trap. Then in filtering script for down trap you can check if this attribute already set to true, and then ignore the event. And yes, you can use %2 and other macros as instance and/or attribute value.

That's strange. Can you show me SNMP trap mapping and part of trap log?

Hi!

Currently there are no way to find how particular IP address was discovered, except for looking at debug log, level 6 at least. I agree that discovery source information should be available. Added to my todo list.

snmp enabled devices like ibm ip kvm and ibm tape library which are connected to switches with drivers are not found,why is that ?

Sorry, I'm not clearly understand the question - drivers not found for tape library, etc. or for switches?

Every event has source object ID. For events created from SNMP traps, source object determined by SNMP trap packet's source IP address. If node with that IP address cannot be found, event will not be created. Can you check that for both down and up traps events are generated?

Macro for IP address exists - %a. Full list of possible macros available here: http://wiki.netxms.org/wiki/UM:Event_Processing#Macros_for_Event_Processing.

I have added "Key" column to alarm log in 1.2.2.

I can add this as configurable option. I don't have time to add this in 1.2.2, so I schedule this for 1.2.3 release.

Hi!

I start building it already Should be available this evening or tomorrow. It was planned to be released much earlier, but I'm overloaded with other tasks...

Hi!

Yes, you should use situations for preventing duplicate emails. Depending on if you have paired event for access point coming up, you can either set situation's attribute to true when you process first down trap, ignore all other down traps if it's set, and clear it on access port up trap, or you can store current time in situation's attribute, and ignore all next events withing some short time interval.

No, there are no default rules for handling SNMP ifdown/ifup traps. You should create them by yourself.

I recently decided to start moving our trap notifications over to NetXMS from what I hope will soon be our old NMS.  We have a number of various model Procurve switches which the system seem to try and detect.  It shows the driver on the general tab as PROCURVE.  However, when we get a trap for link down and then a trap for link up it is NOT clearing the Link down event and it stays up on the device until we manually terminate.  It is detecting the ports correctly from the varbinds, just not clearing.

First traps .1.3.6.1.6.3.1.1.5.3 (link down) followed by .1.3.6.1.6.3.1.1.5.4 (link up).  These appear to be the "standard" down / up noticed and are listed in the SNMP Trap Configuration section.

How do you define rules in event processing policy for create and terminate alarm?

Not sure how it comes up with the port drawings either, but it is wrong.  For example our 4000M switch shows an odd layout of ports 1-22 in slot 1, 0 - 23 in slot 2, 0 in slot 3 and 1 in slot 4.  In actuality there are 6 8 port cards, 1 1 port card.  It also pops up a components tab with nothing filled in.

Can you please send me output of nxsnmpwalk for the following OIDs on this 4000m:
.1.3.6.1.2.1.1
.1.3.6.1.2.1.2
.1.3.6.1.2.1.47.1.1.1.1

Components tab may be empty because switch may not support appropriate MIB.

Also, would like to make a suggestions that you allow clipboard copy from the SNMP Trap Monitor display so it is easier to grab OID's or messages. 

It's already done in upcoming 1.2.2.

Hi!

Do you have libnxcore.so.1 in /usr/local/lib? If yes, try to run ldconfig and then start netxmsd again.

How did you compile agent for Pi? Can you send me config.h from your build? I suspect wrong byte order detection.

Hi!

Looks like encryption is now working for some reason, because server drops connection immediately after key exchange. Can you check server logs as well? Also, try to disable encryption in agent to ensure that it's encryption problem.
