  1. I have added the log level
  2. Then I restarted the agent
  3. Then I restarted the pool on the server
  4. Jumped into the log a here it is:
2020.05.08 14:34:30.615 *D* [                   ] Event sender thread started
2020.05.08 14:34:31.616 *I* [                   ] NetXMS Agent started

2020.05.08 14:35:30.615 *D* [dc                 ] DataCollector: sleeping for 60 seconds

10.6.6.17 is the NetXMS server self
so I again opened the nxagentd.conf and I have put there:

MasterServers=127.0.0.0/8,10.6.6.17
before was just:
MasterServers=127.0.0.0/8

and problem is SOLVED! super Thank You :_)

Also, you can use nxget command - it requests data from the agent, e.g.:

nxget 127.0.0.1 "SSH.Command(host,user,password,ls)"

So I deleted the source node on the parameter, but it doesnt soved it.

It defines where actual data collection will happen, in case of "agent" origin - what agent will be queried. You'll need source node to be set in the opposite case - when you configure DCI on "myserver" node but SSH subagent is on NetXMS server - then you'll have to set source node to NetXMS server node.

Best regards,
Victor

  1. On the NetXMS server I found /etc/nxagentd.conf and added new line SubAgent=ssh.nsm, then restarted the agent.
  2. On the server node I opened 'Data Collection Configuration' and there created new parameter.
    Parameter: SSH.Command(192.168.10.1,admin,mypass,ls)
    Origin: NetXMS Agent  Data Type: String
    Source Node: myserver

Then I go into Object Details of the Node(myserver) and tab 'Last Values'.
Here I see the my parameter, but value is <<ERROR>> , Timestamp is empty.

thank You for any hint

Make sure you add ssh.nsm subagent to the configuratio file of netxms agent running on your netxms server and restart the agent afterwards.
