NetXMS Support Forum

Hi,

this (and other) metrics requires JMX server name as an argument. You define JMX servers in agent configuration file (see https://www.netxms.org/documentation/adminguide/jvm-monitoring.html#configuration) Unfortunately, there is no agent list to return all configured JMX servers on that particular agent (we can add one in next release). So for now you cannot use instance discovery if you have multiple JMX servers monitored by one agent.

Best regards,
Victor

Hi!

Try to use server_name\instance_name in DBServer. Also you can try IP address instead of DNS name.
Check that TCP/IP and named pipes enabled for Native Client.

Another alternative is to create ODBC DSN and switch to odbc driver (use DBDriver=odbc instead of DBDriver=mssql). In that scenario you should use ODBC DSN as value for DBServer.

Best regards,
Victor

Hi!

You should be able to use all the % macros in object tools (same macros as in event processing), so you can use custom attribute to define TCP port for example.

Currently there is no control on local port number - system allocates random port, typically from an ephemeral port range. It should not be a problem for desktop client, as this port is used only on loopback interface. FOr web client it could be an issue though, if you use web connect object tool from web client.

This looks like a bug in the server. Please try upgrading to 4.4.2, if this will not help, please try to run netxmsd under debugger and provide stack trace after crash.

Best regards,
Victor

There is no such option in the driver. However, it is possible to use configuration poll hook to test if node name is "name" and driver is "TELTONIKA", and rename it as desired. Sample script that does this and sets node name to product name:

if ($node->name == 'name' and $node->driver == 'TELTONIKA')
{
   $node->rename($node->productName);
}

Victor


New patch release 4.4.2 is just published. Changes since previous release:

Hi,

try just
59 * * * 6-7
for second schedule - it should have same effect.

Hi,
looks like TCP connection between your workstation and the server is terminated for some reason. Can you reconnect normally after receiving this error? I would suggest checking client log file (it is in home directory .nxmc4/nxmc.log) and server log file with debug level 6 for tag "client.*".
Best regards,
Victor

It is fixed in current development branch (change expected state added to new UI). We will do patch release 4.4.2 soon, fix will be part of it.

Best regards,
Victor

Looks like web UI was not updated. Sometimes restart of Java application server can help, and/or deletion of temporary files of application server.

Best regards,
Victor

We have this planned for 5.0.

Best regards,
Victor

Configuration is correct, so it looks like a bug in agent (or libmosquitto). I will try to reproduce it in the lab.

Best regards,
Victor
