Pls show output of the following from debug console:

sh qu

What are the overall specs of the server? What are CPU and memory for a few days?

I've created a ticket for this: https://github.com/netxms/netxms/issues/3195

This should be fixed in the current version

Sorry, this was overlooked for a while. First guess is that there are some issues with syncer thread. It's not visible in show threads, as there's just one syncer threads. In debug console there's

netxmsd: sh sy
Last run at .........: 16.Apr.2026 15:22:58
Last run time .......: 1 ms
Average run time ....: 119 ms
Max run time ........: 132 ms
Min run time ........: 0 ms

And System -> NetXMS Server -> Server Performance has metrics for it, specifically Server.SyncerRunTime.Last. Pls check if this metric looks reasonable.

Slow log opening might indicate problems with DB performance, DB might need tuning. What are the specs on DB VM, is it dedicated to NetXMS or a shared database? How's CPU consumption and IO stats? How big is the database on disk?
You can also use mysql subagent to collect stats about DB operation - https://netxms.org/documentation/adminguide/database-monitoring.html#mysql

Which database you are using?

Replicated this, created ticket: https://github.com/netxms/netxms/issues/3189

You can do
return DataCollection::ERROR;
this will prevent storing of a value into the DB, DCI will show <ERROR>.

These constants can be found here: https://netxms.org/documentation/nxsl-latest/#const-dci-exitcode

Thanks for the info, developers fixed a few resource leaks in maps, to that could have been it.

Цепочка может уходить весьма глубоко, можно например

for (i : $node.interfaces) {
  println(i.peerInterface.node.name);
}

Не обязательно писать цепочкой, можно раскапывать по одному шагу и сохранять в переменные:

for (i : $node.interfaces) {
  p = i.peerInterface;
  n = p.node;
  name = n.name;
  println(name);
}

но может оказаться, что в этой цепочке какой-то атрибут является null, а не объектом, и тогда все ломается в примере выше, если переменная p будет null, то в следующей строчке, где мы делаем p.node, то есть пытаемся получить атрибут node мы не можем этого сделать, потому что у null нет такого атрибута. Чтоб не ломалось, можно делать проверки в тех местах, которые могут оказаться null, например peerInterface:

for (i : $node.interfaces) {
  p = i.peerInterface;
  if (p != null) {
    println(p.node.name);
  }
}

Или использовать новый синтаксис, появившийся в версии 4.5, называется это safe dereference и если кто-то и окажется null, то попытка обратиться к его атрибуту не завершится ошибкой. Но .? должыть быть в цепочке начиная с первого места, которое может оказаться null и до конца цепочки:

for (i : $node.interfaces) {
  println(i.peerInterface?.node?.name);
}

Peer ноды определяются во время topology poll

А что-нибудь такое:

  for (iface : $node.interfaces)                                                                                                                 
  {                                                                                                                                              
      peerIface = iface.peerInterface;
      if (peerIface != null)                                                                                                                     
      {                                              
          println("Port " .. peerIface.name .. " on " .. iface.peerNode.name);
      }                                                                                                                                          
  }

Which exactly dashboard elements are used on that dashboard?

In Windows task manager in "Details" screen right-click on any header in the table, click "Select columns" and add "User objects" and "GDI objects". Check these values after a day, if they grow or stay stable.

Note the %(username) macro in object tool's command line. This object tool has an input field configured, so when tool is executed a dialog with input field should appear. Username should be entered there. If username is not entered, then command line is formed incorrectly.

You can check actual command line by changing
cmd /c "ssh %(in:username)@%u || pause"
to
echo cmd /c "ssh %(in:username)@%u || pause"
it will just display the command line on the screen.

Also, you can use ssh username specified in node properties, in this cause use this command:
cmd /c "ssh %{ssh.login}@%u || pause"
and remove input field from the object tool.

First of all two first lines should end with ; char.
There is no isInSubnet() method on InetAddress class, but there is contains() method on subnet, so we should go opposite way and check it on the subnet, there's an example here: https://netxms.org/documentation/nxsl-latest/#_instance_methods_18
So, modifying your code:

subnetObject = InetAddress("192.168.56.0", 24);

if (subnetObject.contains($node.ipAddress)) {
    return 1;  // match
} else {
    return 0;  // no match
}


Port view works only for devices for which NetXMS has device drivers, so some of these drivers are capable of getting port information. Zyxel devices are not in priority for driver development due to limited resources.

Replicated that, forwarded to developers
