NetXMS Support Forum

Hello @all,

having here NetXMS V5.0.4 at Linux Debian 12 running. 

Today i installed a new switch (Netgear GS728TPv3 / Software Version 6.2.0.25). At switch UI i see/set my configured VLAN at the ports:

VLAN1 -  g1 - g18, g25 - g28
VLAN2  - g19 - g24


In NetXMS the VLANs for VLAN2 shows on Port g11-g16 !!! The switch is polled via SNMP 2C.

Is this a bug in NetXMS or sends the switch wrong data via snmp?

Having anyone else such an issue?


Greetings

Hi Filipp,

thanks for the hint... I restartet NetXMS server, but the templates where not applied to the NetXMS Server Agent.

The println($node.isLocalManagement); show "true" for the NetXMS Server Agent node.

After that, i imported the netxms_server.xml into NetXMS and deploy the template to the NetXMS Server Agent Node and voila... it worked all DCI's from NetXMS Server are in place...

Thanks for the help...

Greetings
Marco 

Meanwhile i've managed to get the agent on the NetXMS server working again.

In the nxagent.conf i changed:


MasterServers=127.0.0.0/8
in 

MasterServers=<IP_Adress_from_NetXMS_Server>

I deleted the agent object/node in server and recreate it. After that i can get a connect to agent and i can make a configuration poll... :-)

It would be nice if i can recreate the basic DCI from the NetXMS server agent... Can anyonye send me an export of the standard DCI's so i can import this into my installation?

Greetings

Hello @all,

i migrated our NetXMS V5.0.3 Installation from Windows (Win10/MySQL) to Linux (Debian 12/PostgreSQL).

Migration worked so far, all pollings are working, except the NetXMS Agent running at the NetXMS Server itself. Before i migrated the DB the agent on the new Linux NetXMS server was working, the agent was recognized from the server and shows many DCI's which was standard after a clean install of the NetXMS Server.

After the migration of the DB, the NetXMS agent infrastructure object still exist, but the DCI are empty and the NetXMS Server cannot reach his own agent. If i make a configuration poll i see this:

The NetXMS Server gets an "Internal Error" from his own agent...

In the NetXMS Agent log i get this lines:

I think this line:

is maybe for a dev a hint to the problem...

So, have anyone any suggestions what i can do, to get a working NetXMS Agent on the NetXMS Server itself (perhaps with all DCI's which are comes with a clean new NetXMS Server install)?

Hello @all,

noticed that there are no more windows server downloads online, except for users with active support contract... Are there any announcement that i missed?

I never heard or read of this change. I only noticed this cause i take a look in the download section of the NetXMS website.

It would have been nice if you had announced the change a bit in advance, then everyone could have thought about how to deal with it...

Greetings

Hi Victor,

i downloaded and installed NetXMS V4.5.1 a few minutes ago (all ok, NetXMS is running so far). Now i see, that the V4.5.1 version was withdrawn from the website...

Are there serious problems with V4.5.1?

Greetings
Marco 

Hi Filipp,

thanks for your answer. I added the verify-host=false to my configs and voila: it worked again... :-)

Many thanks for that hint...

Hello @all,

since Update NetXMS to V4.4.3 all Checks with the Function NetworkService.Status (with verify-peer=false) failed with error 5

Example:
NetworkService.Status(https://10.99.45.44,verify-peer=false)

Up to V4.4.2 this one works without problems. If URL is reached it throws a Result "0". Since V4.4.3 it always throws Code "5".

NetworkService.Status checks without the "verify-peer=false" option works without any problems.

Has anyone else seen this behavior?

Hello @all,

today i installed the server and web-inferface (windows installer) in V4.4.1.

Server is running and functional, web interface is throwing error message:

Hello @all,

testing the new client here... Small question regarding the pinboard:

- Pinboard is not saved at exit from client
- I cannot arrange the registers in pinboard in a different order

Is that by design oder a bug?

Hello @all,

at my NetXMS Server (Win10, MySQL V5.7.30, 16GB RAM) i see the follow event in the windows event log: 

InnoDB: Over 67 percent of the buffer pool is occupied by lock heaps or the adaptive hash index! Check that your transactions do not set too many row locks. Your buffer pool size is 16 MB. Maybe you should make the buffer pool bigger?. Starting the InnoDB Monitor to print diagnostics, including lock heap and hash index sizes.For more information, see Help and Support Center at http://www.mysql.com. 


Has anyone an idea what buffer pool size i have to use? On this machine is only NetXMS running and no other DB's.

Thanks in advance...

Greetings
Marco

Hi Victor,

thanx for the fast response... downloaded, tried and worked for me... But i have to shutdown NetXMS Server, in cause of a locked library...  Now NetworkService.Status is working... :-)

Many thanx..  :-)

Hi Victor,

please see the agent log in the attachment (made with debug level 9)...
