NetXMS Support Forum

What about EPP rules which are before that one that should send the notification? Could there be some rule with "stop event processiong" checkbox?

Make sure that you start your url with http:// or https://
Windows is analyzing the URL and decides somehow which app should be used for opening. URL like file:///C:/ does indeed open in File Explorer

For delayed notifications pls check screenshots in this documentation chapter: https://netxms.org/documentation/adminguide/event-processing.html#actions

What about Server Action Execution and Notification logs, is there anything there related to the email?

В 5.2 можно вынести в комментарий - макрос %{attr_name} развернется в значение атрибута.

Можно сделать DCI с галочкой Show last value in object overview. DCI нужен скриптовый, скрипт return $node.getCustomAttribute("attr_name"); вернет значечение кастом атрибута.

NetXMS can connect via ssh, send some command and get first line of output of that command as DCI value. See more here: https://netxms.org/documentation/adminguide/ssh-monitoring.html

For SNMP you just need to create a new DCI with origin SNMP and put OID into the Metric field.

However, I can not tell if your specific device can perform pinging and report value via mentioned methods. Ssh is probably more promising, as typically ping command is present on devices.

Depending on what that router supports. If you could install NetXMS agent there, that would be the best way - e.g. this can be done with some newer Mikrotiks that support containers. If not, then you can collect data via snmp or ssh. Or you can put some machine with netxms agent in the proximity of this router.

Are you using desktop client? Legacy or new one? What exactly version of the client? What is the OS?

Hi,

External resources are meant to store URLs. They are visible in the Overview tab of a node.

Custom attributes are for storing any custom information you need. They have inheritance, so you can specify a custom attribute on container and it will be on node under that container. A few use cases:
- If you have a template that needs to be applied only to specific nodes - it's autobind script can check for a custom attribute.
- Check File system: free space on {instance} DCI from Operating Systems->Windows template. Note how threshold value is configured.
- You can add text from custom attributes to your event messages or notification text by using %{custom_attribute_name} macro.

You can have object tool that uses URL from a custom attribute, just use %{custom_attribute_name} in that tool.

Ok, then an alarm should have been generated. I'd check the alarm log for the node, maybe the alarm was terminated after its creation.

Ok, so SYS_NODE_DOWN event is happening. In Configuration -> Event Processing Policy there should be a default rule named "Show alarm when node is down" that should create alarm when such event happens. Is this rule present and enabled?

Ok, next thing to check - it you have a look at Event Log for a node that went from online to offline, what events are there?

Hi,

Can you please share the textual output of status poll for the node when your camera is online and offline

Which client you are trying to use, legacy or the new one?

Чтоб мониторить подсеть нам нужно проверять связь до каких-то конкретных нод, в ней находящихся. Можно пользоваться агентской метрикой NetworkService.Status (для нее нужен субагент netsvc). Например, если на нодах есть ssh, то:

NetworkService.Status(tcp://10.10.1.2:22)


Еще вариант - включить на агенте режим прокси, создать ноды для девайсов из этой подсети и следить за статусом этих нод. Можно наскриптовать какую-нибудь проверку, что если все ноды из конкретного контейнера ушли в даун, то тогда создавать аларм.

Мы пытаемся получать мак адрес в таких ситуациях, но возможно это работает только если мы опрашиваем соседнее устройство. Девайсы у этой сети подключены через управляемы свич? Он опрашивается?
