NetXMS Support Forum

running with lot of issues using netxms:

- ssh - doesn't work, it is using the def one 22 , i have specidicate xxx (tool -> connect -> ssh-22 by def)
- graphe - its printing on some of the interfaces,  on 2 routers
- syslog doesn't work
- core is crashing (approximately every 1h)

the more i dig,  the more things doest worok

SSH - you are mixing up ssh monitoring (when port from node properties is used) and object tools. Pre-configured object tool for SSH open default ssh client without specifying port. Tools are configurable in Settings -> Object Tools.

rest of the issues is not a bug report, we can't help you with this input, without proper details. I've already recommended you to read documentation, it's all covered there in details.
Regarding core "crash" - you need to configure logging to the file, and check why it's stopped and not starting.

System is working fine for years for our customers, in different environments, and with wire range of versions (oldest is still 3.9, if I remember correctly). But if you'll find condition which actually crash core or agents - please share minidump and logs, we'll look into it.

done, i will make that file ready and sedn it over.
Will that help to find out the issuss with  syslog and graphe?

please see about SSH:

Hi Alex,

I'm currently facing an issue with generating the .dmp file after a crash.
I've been able to run the following command successfully

netxmsd -D3 -f

However, when a crash occurs, the .dmp file is not being created.
This is my current netxmsd.conf:

# Configuration file generated on Wed Jul 30 14:51:14 2025
#

DBDriver=sqlite.ddr
DBName=C:\NetXMS\NetXMSDB
LogFile=C:\NetXMS\log\netxmsd.log


Let's also review my installation process to ensure it's correct:
Steps I Followed:

• Downloaded:
  
  • Code Select Expand
    netxms-server-5.2.4-x64
  • Code Select Expand
    netxms-legacy-gui-5.2.4-x64
• During installation:
  
  • Database Type: SQLite
  • Database Path:
    
    Code Select Expand
    C:\NetXMS\NetXMSDB
• After installation, the NetXMS Core starts and works fine.

Problem:
When I tried following the official NetXMS documentation from here:
https://netxms.org/documentation/adminguide/installation.html#installing-from-rpm-repository (https://netxms.org/documentation/adminguide/installation.html#installing-from-rpm-repository)
The Core service does not start properly after configuration.

Could you please review this and let me know if I'm missing something?

please read logs you've shared.

have you spotted anything?

not sure what to say , its clear that there is some issue , is the way of installing right?

Quote from: nichky on August 05, 2025, 02:07:09 PMhave you spotted anything?

Sorry, I can't help you any further.

Your log literally says that connection with PostgreSQL server can't be established on localhost, port 5432 (default).

how about this log (https://we.tl/t-Z6BLtpww94)?

first log one was with database type: PostgreSQL -> CORE doest work at all

second log one is :SQLite -> CORE works for some time

2025.08.05 21:08:49.200 *E* [db.lock            ] Database is already locked by another NetXMS server instance (IP address: 10.100.99.34, machine info: ON-NIKOLA Windows 8 Build 9200)

Another instance of netxmsd is running. Kill all of them, the run "nxdbmgr unlock", then "nxdbmgr check".

https://netxms.org/documentation/adminguide/appendix.html#database-manager

noted, i will be doing that.

fyi: 10.100.99.34 is VPN- ip.
While netxms is running i'm doing VPN (work).
Would be a problem?

also i don't understand this part:
Windows 8 Build 920 - My laptop is Win 11

Alex - we got some improvement


this is what i was getting,  and i had to reinstalled, in order to make it works:

"netxms the net cms core service on local computer started and then stopped.Some service stoped automaticly if they are not in use by other services or programs"

as per your advice  "nxdbmgr unlock", then "nxdbmgr check" fixed

see here (https://we.tl/t-c1bnuAs7xH) pls

it seems like the VPN cost the issues.
i will be not doing VPN just for make sure that this costed the issues

Alex - i had some of CORE crashs today, what can u get from this log (https://we.tl/t-XBPMJyLdQY)?

i'm really confused.
It looks like that port 5432 makes a lot of drama.
I did check that is PostgreSQL.
The interesting part is i dont have it installed on my laptop (both)

that why i asked Alex check if i'm installing NetXMS properly, also i noted if i chouse  PostgreSQL the CORE doeset run at all.

do u have anythign to add?

probably nothing you can add.
Normal if i have issues with the basic install to ask for help.
Im  not only one having issues with that.
I did what u asked me to do.
Still having an issue (better then how it was)

Yes, nothing I can add, tbh.

I've provided you with all the information and keywords, next step it only install it remotely for you.

do we have that option , greate. Whenever you're ready - Thanks
