Hello @all,

is it possible to log the user sessions (User, Client name, Client Adress, ...) to the NetXMS event log?

Greetings

Hello @all,
 
i have a DCI which collect Date/Time via Powershell every hour. For Example here the last Values from the history of this DCI:

I created a Threshold to get an alarm if the value NOT change in the last 24h:

Function: "Diff with previous value" 
Sample: 24
Operation: "> : greater than"
Value: 0
Activation Event: <Type Warning>
Dectivation Event: <Type Normal>
 
But the threshold throws no alarm, even if change the sample count to 1 or 2.
 
Is this the false threshold function to compare a string? But in the NetXMS Documentation for Thresholds this function should work with strings...

---
Diff with previous value
Delta between the last and previous values will be used. If DCI data type is string and the last and previous values match, system will use 0, and if they don't - 1.

Where are my fault?  I am thankful for any hint...

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?

Greetings

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,

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.

Greetings
Marco

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?

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,

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,

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...

Hello @all,

today i updated NetXMS to V4.3.0 (Win10, MySQL). In cause of this, the ServiceCheck DCI's are not working anymore. So i would migrate these to the  NetworkService.Check  function.

I changed the agent.conf of the NetXMS Server Agent, deleted the subagent portcheck.nsm entry and added the subagent netsvc.nsm entry...

I restart the agent but the subagent doesnt load... (please see attachments...)

Where is my fault? What i am doing wrong? Any help will be welcome... :-)

Hello @all,

(please see screenshot from install at attachment)

But we use MySQL as database.

The netxmsd.conf was completly rewriten from installer with postgress config data.

So i had to copy my old MySQL config into the netxmsd.conf file. After that i had to do a manual upgrade the database with "nxdbmgr upgrade".

After that, i can start the NetXMS Core Service.

Maybe a Dev should take a look into the setup process...

Hello @all,

i want to monitor the windows firewall of our servers with the WindowsFirewall.State.

If i create a DCI with WindowsFirewall.State(public) (for the public firewall) so i get the value "0" (Firewall is off). If i activate the windows public firewall the DCI value doesn't change, it remains at "0".

How does the WindowsFirewall.State() work? Is "0" not the value if firewall profile is off?

Thanks for any help...

Hello @all,

today i updated NetXMS Server (Windows 10 64bit, MySQL 5.7) from V3.7.130 to V3.8.226...

The NetXMS Server seems to run properly but the NetXMS WebUI + Reporting Server (both same Version as NetXMS Server) doesen't start.

The NetXMS Agent (at the NetXMS Server) drops thousands and thousand of errors per second in Windows Eventlog (Message: "CRT Error"). Open the NetXMS Console seems to hang in cause of the thousands of Windows Eventlog Alarms from Agent. We have high CPU Usage on NetXMS Server for the windows eventlog service in cause of the many Errors generated by Agent.

Due to this behaviour I have restored the complete NetXMS Server to the previous Version (V3.7.130).

Are there any prerequesits for V3.8.226 i have to do or install on NetXMS Server that i can upgrade to V3.8.226 ??
