NetXMS Support Forum

Hi

we are experiencing a strange issue since we upgraded from 1.0.11 to 1.2.3. when the configuration poll checks the capabilities of a system it seems to be unable to find the NetXMS agent AND the snmp agent together.
if NetXMS Agent Service is running, it recognizes the Agent but not SNMP. if you stop the service, it recognizes SNMP again.
this means, when we run the NetXMS Agent we are unable to check SNMP values on our systems!

we experienced this on several Windows 2008 R2 systems, an issue we didn't have before.
most of the systems still work, but on every one i run the configuration poll, the SNMP stops working as it doesn't show up in the capabilities anymore.

edit: it seems to be only an issue with manual configuration polls. we upgraded yesterday and we were not yet flodded by errors

any idea on this?
thanks!

I can confirm this issue.

We were reading temperature via SNMP on the NetXMS server itsself since v1.0.x. After a number of upgrades up to 1.2.3, this still worked, until I added some unrelated external parameters to the agent configuration and did a configuration poll.

After a day or so it may get back on its feet, though, so it could be just manual polls.

i agree, after a day or two it sorted things out again. still,  it's an issue to be taken care of.

Hi all!

Can you please post number of nodes/DCIs being monitored and server configuration settings (I'm interested in poller counts and timeouts). Also, did you check internal server queues?

Best regards,
Victor

Hi,

Total number of objects: 14715
Number of monitored nodes: 848
Number of collectable DCIs: 7182

Config variables are attached.
Note that I did play around with the poller counts recently, but I can still reproduce the problem.

First, I do a walk on the desired OID in the MIB browser, this shows the results.

I then set debug to 9 and did a configuration poll:

Log was very helpful, I've found a problem. 1.2.4 should work as expected.

You can open server's debug console (either using nxadm command line tool or by selecting Tools -> Server Console in Java management console) and enter show queue command. In normal circumstances size of all queues should be zero or near zero. High value for any queue, especially if it keeps high for a long time, usually indicates some problem. There are also predefined DCIs on NetXMS server's node which collect some internal metrics of the server.

good news!
will 1.2.4 be released soon? or will there also be an update for 1.2.3 addressing this problem?

thanks for clarification, didn't know of these queues.

regards

confirmed, server version 1.2.4 fixes the problem
