NetXMS Support Forum

Hello @all,

played here around with windows event logging in NetXMS V5.2.4 (Debian, Postgres).

Therefore the database size blowed up. I have changed serveral retention values an the housekeeper is running a few minutes an do it's best, but the database don't shrinks.

What can i do to shrink the DB? Deleting and restoring?

Hello @all,

since update to NetXMS V5.2.2 (Debian/Postgresql) i see the following error message at every template i click on (in template view):



(Message: Cannot open data collection configuration for <TemplateName>: Invalid thread access)

The view doesn't actualize, i doesn't see the DCI's from the template i choose...

Otherwise, NetXMS seems working normal...

Having anyone else this behaviour?

Hello @all,

today i updated from V5.1.3 > V5.1.4 (Linux Debian 12, PostgreSQL V15 DB).

After update, the NetXMS Server is running for a few minutes then crashed an restartet. I've rebooted the server, but the behavior doesn't change.

I've restored the server from backup to V5.1.3 and NetXMS ist running fine again.

Have anyone else this issue?

Greetings
Marco

Any chances we can get remote access to your device for a few days? SNMP-only access is enough, it can be some test device not connected to real network

Hi Filipp,

sorry for the - very - late reply. Meanwhile Netgear released a new firmware with a vlan/snmp bugfix. After upgrade to newest switch firmware the VLAN infos in NetXMS are correct...

Hello @all,

having here a similar problem with a Netgear GS728TPv3.

Ports Tab ist empty, Interface List shows VLANs at wrong interface or VLAN fields are empty in interface List...

The correct values are:
VLAN1 is on port 1-18
VLAN2 is on port 19-24

NetXMS is using the GENRIC Driver.

Using here NetXMS V5.0.6 (Linux Debian / PostgreSQL)

Must i use a vendor driver for this switch type too?

Hi Tatjana,

thanks for your post.

I've tried these and it works so far...  Now, i'd like to migrate my previous config to get Windows Eventlog to the wineventsync.nsm subagent.

Therefore i created the following config:

SubAgent=wineventsync.nsm

[WinEventSync]
EventLog=Application
EventLog=Security
EventLog=System

[WinEventSync/Security]
IncludeEvent=4624
IncludeEvent=4634
IncludeEvent=4647
ExcludeEvent=0-65535

[WinEventSync/System]
SeverityFilter = Error,Critical

[WinEventSync/Application]
SeverityFilter = Error,Critical

All of it works, except the SeverityFilter of the System Eventlog. I tested this with 

eventcreate /T ERROR /ID 1000 /L SYSTEM /D "TestError"
but i dont see any entrys in the NetXMS WindowsEvents...


If i do so with the Application Log 


eventcreate /T ERROR /ID 1000 /L APPLICATION /D "TestError"
the Windows Event Entry in the NetXMS WindowsEvents is created...


Is there a wrong entry in my config (please see above...)

Hello @all,

i want to create an event from every user session (showed in NetXMS register "User Sessions") so that i get every user logon/logoff in the NetXMS event log from every node.

Is there a chance to create those infos in the NetXMS event log?

I would appreciate any help/tips.

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?

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...

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...
