NetXMS Support Forum

Quote from: tolimanjo on September 30, 2025, 05:41:40 AMAnyway, putting an HTTPS-HTTP proxy in front of the server (and specifying https:// on the client) fixed the problem.

Indeed, with nginx and a few lines in config it works via https.

As for now it doen't look like offering much - no information on nodes, dashboard not working; will be implemented one day, I hope.
Thq question is: the application does not notify about alarms as I can see. Is that correct?

Quote from: Filipp Sudanov on November 19, 2025, 07:03:12 PMI'd recommend to migrate to MySQL, MSSQL or Postgres (I personally prefer the last option, but it's just whatever you are comfortable with).

Works with PostgreSQL (default settings) without issues - confirmed. And once again - thank you 

Quote from: Filipp Sudanov on November 21, 2025, 03:43:38 PMIs this still with SQLite?

Yes. I remember the advice on using any other DB and I might switch to another one later, although that would be too much for my needs and I preffer concept "The easier the better", i.e. the less extra software. But generally speaking if SQLite is provided as an option - it has work correctly.

So, running NetXMS service with -D 9 argument brought following as for now:
Thread "Recurrent scheduler" does not respond to watchdog thread
Log doesn't seem to contain much useful information .. should I upload mini or full dump somewhere?

Quote from: Filipp Sudanov on November 19, 2025, 06:58:24 PMYes, messages about
Thread "Syncer Thread" does not respond to watchdog thread
Thread "Recurrent scheduler" does not respond to watchdog thread
mean that something is not good with the server process (netxmsd).

Exactly. I'll try to check via Process Manager the thread stack - if/when it hangs up again.

Quote from: Filipp Sudanov on November 19, 2025, 06:58:24 PMFirst thing to check memory consumption by netxmsd, may be it goes up and system starts swapping.
What are the specs of the machine? What DB do you use?

Supermicro X10DRi-T, 64 Gb RAM, 2x Xeon E5-2683 v3, 1 Tb NVMe SSD with paging file.
Does not look like lack of memory, but I'll be watching that too.

Quote from: Filipp Sudanov on November 19, 2025, 06:58:24 PMIs the DB on the same machine?

Yes

Quote from: Filipp Sudanov on November 19, 2025, 07:03:12 PMFrom another thread is seems that you've installed with SQLite. This could be the reason for server locking.

I'm aware of the fact that SQLite is not made for heavy loads and I'm going to monitor less than ten devices (home server, dad's pc, my desktop, few routers - mostly not to worry about HDDs in RAID and to be sure WireGuard is ok). But that hanging up has happened when NetXMS was freshly installed and was monitoring only itself, then I've added one MikroTik router monitored via SNMP with default settings, - which is hardly any bit of load.

Quote from: Filipp Sudanov on November 19, 2025, 07:03:12 PMI'd recommend to migrate to MySQL, MSSQL or Postgres (I personally prefer the last option, but it's just whatever you are comfortable with).

One you've configured parameters for the new DB in netxmsd.conf, and ran "nxdbmgr init" to initialize new databases's tables, you can use

nxdbmgr import <path-to-your-sqlite-db>

to migrate your exising sqlite database into the new one.

I'll keep that in mind, thank you - I really appreciate your help

We'll see how it works ...

Hi, everyone!

NetXMS becomes unresponsive via web-interface and Client both after about couple of hours after being started - without any specific reasons or any interaction with it.

No events in Windows Event Log about that found.

Is there anything else I could provide to help fixing/resolving the issue?

Quote from: Filipp Sudanov on November 14, 2025, 07:44:16 PMAlso note that SQLite is for testing only as it may not handle multiple parallel queries well. But is should be fine for a few tenths of nodes.

Yep, thank you, - I've read about that; although I hardly have any experience with databases.
It's basically for less than 10 computers - home server, desktop etc.

Btw - I'm not sure that hardware vendor/model/serial number recognition is strictly maintained (sure, there are thousands of devices), but just in case - it does not work 100% correct in terms of fields (WD Blue HDDs, also Kingston memory is not recognized at all):

Quote from: Filipp Sudanov on November 14, 2025, 12:06:10 PMIn case of SQLite database login and password is not used. There is no need to check "Create database and database user before initialization". Just fill in "Path to database file", folders in that path should exist after installer finishes extracting files, so C:\NetXMS\server.db should be fine. NetXMS will create the database automatically.

Oh, thank you so much - indeed that worked: installation was successfully completed, now "NetXMS Core" service is running, log does not contain any error messages and login at web-interface (installed afterwards) works ok.

I'd suggest - it would be handy if "Create database and database user before initialization" and afields below it would be grayed out in the installer if SQLite is selected.

Hi everyone!

I'm trying to install NetXMS Server on freshly installed Windows Server 2025 as Administrator like following:

• Path: default (C:\NetXMS) (1)
• Selected Components: default
• Select Additional Tasks: default (Initialize database etc - all checked)
• Initialize Database:
  
  • Database type: SQLite
  • Path to database file: C:\NetXMS\database\netxms.db
  • Create database and database user before initialization: checked
  • DBA login name: admin
  • DBA password: netxms

In the end of installation console window appears:
NetXMS Database Manager Version 5.2.7 Build 5.2-483-g0fe7ba4e30

Creating database and user...
Database creation is not implemented for selected database typeUnable to create database or user

***** PRESS ANY KEY TO CONTINUE *****
which according to Process Explorer is a result of command run by installer:
"C:\NetXMS\bin\nxdbmgr.exe" -c "C:\NetXMS\etc\netxmsd.conf" init -P -F sqlite -C "admin/netxms"

File "C:\NetXMS\etc\netxmsd.conf" contains following: (2)
DBDriver=sqlite.ddr
DBName=C:\NetXMS\database\netxms.db
LogFile=C:\NetXMS\log\netxmsd.log

Service "NetXMS Core" is not running and restarting it manually results in just it getting stopped.

I tried to add following lines to nextxmsd.conf:
DBServer=localhost
DBLogin=admin
DBPassword=netxmsIt did not help any bit.

General question: what is wrong and how can I fix it?

Extra questions:

• Would it be correct to install to "C:\Program Files\NetXMS" ?
• Should nextxmsd.conf contain DBServer, DBLogin and DBPassword parameters? - They are not added automatically
