v2.0.8 to v2.2.12 upgrade issue

[cserzs]

Hi,

I have upgraded my NetXMS server from v2.0.8 to the latest version (v2.2.12) and following this in case of some nodes (looks like that this depends from the physical type of the node device) appeared a question mark on the object browser icon and its interfaces disappeared. Despite this these nodes works properly (data collection and alarms etc.).
Before upgrade process there was no such issue.
What could be the problem and how is possible to eliminate?

Thank you in advance.
Regards, Zsolt

Quite strange. Looks like it get empty interface list from device. What device driver is used? Can you provide SNMP walk results on ifMib?

Best regards,
Victor

Hi Victor,

I have checked the ifMIB walk and I found that this feature does not implemented in this type of device.
Besides this I installed an older version (v2.2.2) NetXMS test server to verify the previous display mode.

Please find in the attachement two screenshoots about the two different NXMC versions.
So, in case of older versions the nodes without ifMIB feature were displayed with "unknown" named interface element without question mark.
I think that the older indication mode was a little more logical.

It actually looks like SNMP is not detected at all with new server version. Could you set debug level to 6, run configuration poll again, and check or post here relevant lines from the log (usually those with name or IP address of the node in question)?

Best regards,
Victor

I hope this will be good for debugging.

Hi Victor,

One more comment regarding this issue:
As I wrote the problematic nodes works properly but after all I found that in case of nodes with question mark the trap processing based event generation does not work. Only the threshold based DCI alarms works.
