Thanks Alex, super helpful.

Добрый день,

Метрика указана неверно. System.Registry.Value(*) — это шаблон из каталога метрик агента, а не готовая метрика: у неё два аргумента, путь к ключу и имя value. Для вашего случая:

System.Registry.Value(HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Safer\CodeIdentifiers,{instance})
{instance} нужно добавить и в description, иначе все шесть DCI получатся с одинаковым именем.

С литеральной * агент не может разобрать первый аргумент как корневой ключ и возвращает "unknown metric", поэтому созданные DCI сразу уходят в статус unsupported — в event log ноды должно быть шесть SYS_DCI_UNSUPPORTED. В Data Collection в режиме просмотра проверьте, что включён показ unsupported DCI.

Instance discovery настроен правильно, external list здесь не нужен — System.Registry.Values(...) возвращает именно имена values.

Отдельно: сам DCI, на котором настроен instance discovery, в режиме просмотра не отображается, в списке видны только созданные по нему DCI. Это ожидаемое поведение.

Hi Alex,

I've sent support an email. I believe I'll need a new license key as my Hardware ID is red.

Hi,

That error means the server is not counting your license as valid — it falls back to the built-in limit of 250 managed nodes and blocks creation above it. "Unlimited" in the key is not enough by itself: a key is ignored if it is expired, capped to a version below 6.2, or bound to a different machine, and none of that is logged.

Run nxlicmgr list from the server's bin directory. Check that the key is actually listed, and that Quantity, Hardware Id, System Id, Version and Expiration are all green. Red in any column is your answer — Version red means the key predates 6.2, Hardware Id or System Id red means it was issued for a different machine.

If the key is missing from the list, or anything is red, write to [email protected] with that output — those cases need the key re-issued.

Good Evening,

I am trying to add some new nodes, and getting Cannot create node object XXXX: License Violation. The server is running 6.2.3 on Windows, and I do have a license with unlimited nodes. I'm not sure where to go from here.

Thank you,

Chris

update: another issue is fixed. this one is tracked here: https://github.com/netxms/netxms/issues/3593

it's fixed already, will be included in next release

Not sure if I am the only one but after upgrading to 6.2.3 I always get the following error when closing out the program.

Доброго дня
NetXMS Server Version 6.2.1 Build 6.2-513-g227556c428
NXCP: 5.62.1.56 (AES-256, 3DES, AES-128)
Built with: g++ (Ubuntu 13.2.0-23ubuntu4) 13.2.0


Пытаюсь создать параметр в ноде из реестра windows машины.
-Instance discovery по листу от агента
--System.Registry.Values(HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Safer\CodeIdentifiers)
-Метрика
--System.Registry.Value(*) формат string

Dci появляется на мгновение, и пропадает.

Instance discovery poll отдает, что параметры он создать пытается, но опять же ничего в списке не появляется
[25.08.2026 10:02:41]       Creating new DCO for instance "TransparentEnabled"
[25.08.2026 10:02:41]       Creating new DCO for instance "PolicyScope"

[25.08.2026 10:02:41]       Creating new DCO for instance "DefaultLevel"
Пробовал еще через external list в агенте забрать
ExternalList = HostName:powershell -NonInteractive -Command "Get-ItemProperty -Path 'HKLM:\SOFTWARE\Policies\Microsoft\Windows\Safer\CodeIdentifiers'"
но опять же dci просто пропадает сразу
Что я не так делаю?
