NetXMS Support Forum

You can create four nodes enabling "Communication through external gateway" checkbox on them (actually, on three of them, so one of them will be treated as main node and NetXMS will read network topology for it).
For each node you can now set specific port.
If you want all DCIs on one node, you can use Source Node Override in DCI properties.

The syntax is URL-like
http://hostname:port or http://IP:port

It's adviced to put e.g. nginx as reverse proxy to add ssl (then url would obviously by https://), but if you use VPN you are good with just http

Hi,

I would like to integrate a measuring system using the MODBUS protocol to my NetXMS system.
It contain an RTU-TCP MODBUS converter module and four measuring devices connected via RS485 bus.
The converter module has an IP address, through which the four measuring devices can be accessed, but each on a separate port number.
Is it possible to request in NetXMS all four instruments via MODBUS from the same IP address but different port numbers?

Thank you in advance.

Hi Alex,

I upgraded to version 5.2.5. Then, when I added the line "Module=webapi" to the \\NetXMS\etc\netxmsd.conf file, the core NetXMS service
started without any problem (it always stopped with the previous version).
Despite this, unfortunately, the mobile app still does not connect to the server (error code: 404).
I access the server from my mobile phone via a VPN connection.
What is the syntax of the "Hostname or IP" parameter in the mobile app?

BR, Zsolt

I'd suggest to experiment a bit - you can make a new template with just one DCI and see what happens when you export or import that.

For duplicates - it's controlled by GUID of each template that is included in the .xml file. So if you import it back, it will replace the original template, even if the name is different. But if you change the GUIDs in the .xml, it will import as a new one.

Only "Replace templates" option is relevant if your .xml contains only templates. If it's not checked, then if template already exists, no changes will be done to it.

Just tried a fresh install on Win 10, HTTP / HTTPS buttons work from a dashboard. But other elements of dashboard could affect things.
Do you have any error messages in C:\Users\<Your username>\.nxmc4\nxmc.log when you try to use these dashboard buttons?

I will dig into this some more.  I used the same Object Tool for the button, as I have used under the node's Tools > Connect  menu.   I can launch HTTP and HTTPS from the Connect menu, but still nothing from the Dashboard.   Not sure why this is happening, or if it's client OS/ client platform specific.  I'm on Windows 7 and Windows 10 for both Client's where I've had this happen, so it's not (client) machine specific for me. 

I'll keep messing with it; For now my work around is just to use the Connect Menu, but having it work in the Dashboard as a button is the end goal. 

No problem Filipp.  Appreciate the response.   

You're correct; I have multiple hierarchies so nodes exist in multiple places (i.e. it might be listed in my physical topology under "Core Routers" but then it might also be listed under Manufacturers > MikroTik... I think this is just for my visual benefit / sorting more than anything else.  I know I tend to over-complicate everything haha). 

Thanks again, and look forward to the fix (noting that B would be my preference, so we don't ever delete a bunch of custom attribute values...like keys/passwords/etc that could be impossible to recover or recreate easily).

Yes, if you have table DCIs configured.

But this issue is already sorted in 5.2.6

Hello, I tried to install the NetXMS version 5.2.5. This version of the server works without problems, but my client (console) freezes constantly, remains in a state of not responding. There is no rule when console is frozen, simply after a few clicks on the icons of the objects in the tree view, the screen remains frozen and the current server time stop, and the Windows system reports that the application is in the status of not responding. I waited up to 10 minutes but the console does not return to normal operation.
After the forced close of the console (close task in Task manager) and start console again, everything works correctly. I looked at the log from the server and I don't see any server error, obviously the problem occurs on the console. Does anyone know this problem and maybe have a solution for it. I have many years of experience working with NetXMS version 3.2 and I have never encountered a problem similar to this.

Thanks for any help,

Tomislav
