Hi, there. We decided to move our production NetXMS server to a new computer server. With this idea in mind. I did the following:


1. backed up the database file of the production NetXMS server.
2. In the new computer server, I installed:

2.1 Ubuntu 20.204
2.3. mysql Ver 15.1 Distrb 10.3.34-MariaDB

3. I moved the backed database to the new computer server

4. I restored the backed database into the new computer server

5. I installed the latest NetXMS server version in to the new computer server
at the final of this procedure appeared the following steps:

###
Additional steps required:

1. Edit default configuration file (/etc/netxmsd.conf)

2. Load database schema

   nxdbmgr init

3. Start daemon with command:

   systemctl start netxms-server

###

I omited the step 2. Because, I want to use our current database.

In the step 3, when I executed this command sent back on my end the following message:

Failed to start netxms-server.service: Unit netxms-server.service not found.

I run the following command:

sudo systemctl status netxmsd
● netxmsd.service - NetXMS Server
     Loaded: loaded (/lib/systemd/system/netxmsd.service; disabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Thu 2022-06-02 19:25:39 UTC; 18h ago

What I did wrong?

Any comments are welcome.

Hi, there. We are using NetXMC ver. 4.x  We decide to add a Telegram bot service into the netxmc server. But, It doesn't work. Beacuse an image worth than a thousand words. I Attach it

Testing the Telegram channel using the send notification option from the Tools menu
Notification to the Telegram bot has been enqueded. Then the Telegram configuration changed to error status on the Notification channels.

Hey, there. When I upgraded to NetXMS server 3.7 from NetXMS 3.6 the computer screen sent the following message:

Database is locked

If you want to upgrade netXMS server succesfully, please type:

nxdbmgr unlock

Then

nxdbmgr upgrade

Finally

sudo systemctl start netxmsd

P.S. It works well with Desktop Managment tool 3.6 so far.

My best wishes
