Да, из snmp данные можно собирать в таблицу, вот в этом вебинаре это подрбно разбиралось:

Второй вариант - instance discovery - для этого определяется один DCI у которого на закладке instance discovery описывается OID начиная от которого сервер сделает walk. И на основании этого DCI будет создано много экземпляров DCI по одному на каждый OID.
Если нужно больше информации с примерами, пишите

Можно через NXSL - это встроенный скриптовый язык, можно на любом объекте сделать "Execute script".
https://www.netxms.org/documentation/nxsl-latest/#func-createnode

Можно через nxshell - там можно писать код на Jithon, оно подключается к серверу через то же API что и десктопный клиент. Вот какой-то пример создания ноды:

parentId = objects.GenericObject.SERVICEROOT # Infrastructure Services root

flags = NXCObjectCreationData.CF_DISABLE_ICMP | \
        NXCObjectCreationData.CF_DISABLE_NXCP | \
        NXCObjectCreationData.CF_DISABLE_SNMP

name = "Node created by nxshell"
cd = NXCObjectCreationData(objects.GenericObject.OBJECT_NODE, name, parentId);
cd.setCreationFlags(flags);
cd.setPrimaryName("0.0.0.0") # Create node without IP address
nodeId = session.createObject(cd)
print '"%s" created, id=%d' % (name, nodeId)


И еще можно через web api (web api для этого нужно установить - это отдельный war файл, так же как и у web UI).
https://www.netxms.org/documentation/adminguide/rest-api.html#create-object

You have to fill in all the fields:
Database server: 127.0.0.1
Database name: any name - a new DB with this name will be created
Login name: any name, postgres user with this name will be created
Password: any password for the above user

What version of client is that? Is it legacy or the new one? Have you tried latest 4.4.3?
What actions do you perform to get to that error - mib explorer on node or something else?

Yes, it would be valuable for NetXMS to have support for these devices. Could you possibly provide remote access to these devices for some time - this would be the most efficient way to develop drivers?

It's a bug, was fixed couple of days ago, if there will be another patch release for 4.4, fix will be there, otherwise it will be in 5.0 which should be out in December

А как выглядят настройки notification channel (если убрать пароли) ?

Yes, doing this from script is better as you can control web service reply. To use web services from script, you have to create a web service definition under Configuration->Web service definition. For example let's create one named "example" with url http://example.com

Web services are called via an agent, typically agent which is running along with the server is used. Configuration file of that agent should have
EnableWebServiceProxy=yes

Now if you do "Execute script" on your server node and try the following script:
result = $node->callWebService("example", "GET");
println(result->success);
println(result->errorMessage);
println(result->agentErrorCode);
println(result->httpResponseCode);
println(result->document);
It will perform GET request and would print the result.

Alternative way is to use getWebService(webSvcName) method on node, this would create WebService object which has get(), post(), etc methods.

You can use GetServerNode() function instead of $node to get your netxms server node.

Nested custom attributes are not supported. But you can get all the data you need within the script, either by using object attributes, e.g.

$node->ipAddr

or by calling expandString method of NetObj, Event or Alarm , e.g.:

$node->expandString("%n")

Configuration polls are executed periodically on their own schedule (previously it was so that configuration poll was executed only if status poll detected node up situation, but that had issued - e.g. SNMP community string changed and that required conf poll to find the correct one).

For tunnel nodes, however, conf poll should be scheduled right after tunnel is established, so you can try that.

There is no way to force a poll from NXSL, I've created an issue so at some moment of time this could be added: https://track.radensolutions.com/issue/NX-2480

A bit crazy approach which might currently work - we have an option to redefine poll intervals using custom attributes, e.g:
SysConfig:Objects.ConfigurationPollingIntervalso status poll hook can detect that node comes up and set such custom interval (with value say 60) and conf poll hook would delete this custom attribute.

Is it legacy or the new web UI. On what OS Firefox is running?

First advice would be to try latest version of nxmc, for 4.3. it's 4.3.7

Здравствуйте,


Какое-то краткое описание есть тут, возможно оно устарело
https://www.netxms.org/documentation/adminguide/quickstart.html

логика процесса такая:
event (событие) -> action (действие) -> notification channel


при переходе в node down (а также при срабатывании трешхолда и много чем еще) происходит событие. Дальше есть Event processing policy (EPP) - набор правил где решается, что по каждому событию делать.

в правиле EPP может вызываться действие

действия конфигурируются в Configuration->Actions. Нас интересует тип Send notification. Тут нужно выбрать конкретный notification channel.

это настраивается в configuration -> notification channels. Нас интересует драйвер SNMP. В Driver Configuration пишутся параметры для дравйвера в виде
параметр=значение
описание параметров тут: https://www.netxms.org/documentation/adminguide/event-processing.html#drivers


Когда notification channel сохранен, по правой кнопке мыши по нему (в новом клиенте, не legacy) будет пункт send notification - так можно проверить что что-то шлется

И в 4.4.3 добавили несколько макросов:
-  New event processing macros %d (DCI description), %D (DCI comments), %L (object alias), and %C (object comments)

The option to get older release on Debian is to compile from sources, but this might be a bit complicated.

What about the first option - can you upgrade your current installation of netxms and migrate the database then?
