It would be nice to be able to have checks that would show or alert on duplex mismatches on links between devices. Like wise it would also be beneficial to have indicators on the map the shows differences between interfaces that are 10-100M or 1-10GB etc  or a difference in line width if the links are 100m vs 10GB 

Hello,

Would it be possible to extend/add System.CPU.Count() metric provided by subagents/linux with parametrized one that would enable count of online/offline CPUs in the system.

Example system with 24 cores with 2 cores online:
...:# lscpu --online --extended
CPU NODE SOCKET CORE L1d:L1i:L2:L3 ONLINE    MAXMHZ    MINMHZ       MHZ
 12    0      0    0 0:0:0:0          yes 3200.0000 1200.0000 1197.3630
 13    0      0    1 1:1:1:0          yes 3200.0000 1200.0000 1197.3240

Metric is provided via sysfs:

# cat /sys/devices/system/cpu/present
0-23

# cat /sys/devices/system/cpu/online
12-13

Etc:
- on this exact system System.CPU.Count will return: 14 for number of CPU's.

thank you,

Hi,

I would expect that these devices support SNMP. If this is so, you need to enable snmp on the device and run configuration poll in NetXMS to check if SNMP capablitiy is detected (it's visible on node's Overview page). When this is done, you can use MIB explorer to walk available OIDs and add data collection items.

The other possible approach is to use ssh - in node properties you can specify ssh password or key. Or, if you have many devices, credentials can be specified in Configuration -> Network credentials - these will be auto-probed. If ssh credentials are ok, on configuration poll SSH capability should become "YES".

And, finally, if your device runs under linux, you can try generic NetXMS agents - but this depends on platform/cpu and not necessarily would work

Hello,
I'm new to NetXMS.
Someone can tell me if there are templates / method to monitor Storage SAN?

Any suggestion will be appreciated

Hello,

Q: Was it working on older versions or this is new setup?
A: Unknown. This is a new/clean setup. Specific is tunneled agent setup. And agent uptime monitoring (which pointed out issue).

Q: What exact version of openssl package you are using?
A: Package: libssl3, Version: 3.0.11-1~deb12u2, APT-Sources: http://deb.debian.org/debian bookworm/main amd64 Packages

Br, Ales

Tried clean test server install with just the node that do not work and it works on test server.
Tried renaming and then recreate the node that does not work and now snmp v3 works on the new node on production server.
Odd issue that only snmp v3 is not working on some old nodes.

I will recreate all nodes to be safe.

Agent crashes within OpenSSL library (specifically within EVP_PKEY_CTX_new) and I do not see any obvious problems with calling code. This part was not changed for quite some time. Was it working on older versions or this is new setup? What exact version of openssl package you are using?

Best regards,
Victor

nxshell is integration tool, that allows python code to interact with netxms server. For Windows GUI client you need to install this: https://netxms.com/download/releases/4.5/netxms-client-4.5.6-x64.exe

Current Windows WEB UI installer includes web api as well. It can be reached at http://127.0.0.1:4788/api/
War file itself is located in C:\NetXMS-WebUI\jetty-base\webapps\api.war

Yes, debug log on level 6 would be beneficial. Couple of options
 - use some netxms agent in proxy mode and take the log of it
- use some test installation of netxms server that has just a couple of SNMP nodes (it's also worth to unmanage the node that represents server itself to minimize logged stuff)
