Hi,
i need to have some information:)
Is possible to get an allarm when an host's cable is disconnect?
Thank you in advance and sorry for my bad english.
Hi!
You mean NetXMS server itself or monitored node? For monitored node, server will generate SYS_NODE_DOWN event if node is unreachable. You can create a rule in event processing policy to send email, generate alarm, etc. as a reaction to this event.
Best regards,

thank you for the answer:)
i mean for the monitored node. SYS_NODE_DOWN indicates that the node is unreachable, but is'nt possible to differentiate if cable is disconnect or if node is shutdown ( I don't know if this reasoning is right). i need an event that signal exclusively that node's cable is disconnected. It's possible obtain this?^^
Thank you again.
It general, it is not possible to distinguish from outside if node was shut down or cable was disconnected. The only situation where it can be distinguished that I can think of is following:
Assumptions:
1. If node is off (shutdown), it still have power and link on NIC is up
2. Node is connected to managed switch and port is known
Then you can check port state on switch - if it is down, then most likely cable is disconnected (or node was completely powered off). If it is up, but node is not responding, then node was shutdown.
Also, if node in question is a server with management board (like HP iLO), you can double check server state via management board.
