I need to get an alarm when a server is up and not when it is down. How?

[stoffmann]

Hi,

I know this sounds strange, but let me explain why I need this.
We have some test servers we only need 2 to 3 times in  the year and we pay for them only when the are running on a hourly base.
It happens that we miss to shut down these servers which leads to unnecessary costs.
So what i need is:

• A daily alarm if the server is running
• No alarm if the node is down, like NetXMS is doing by default I think and I found no way to change this. I can't find what is fireing the "SYS_IF_DOWN" event.

Can someone give me a hint on ho to achieve this?

Best regards

Stefan

I would create a DCI on that node of type Internal with parameter Dummy. Set custom schedule for this DCI so that it will be collected once per day at some time. In transformation script of this DCI:

return $node->state & NodeState::Unreachable;

This DCI will be 1 if node is unreacheable or 0, if reacheable (or you can modify that in the transformation script).
Then just create a threshold for this DCI and probably a separate event for this.

Alternatively you can use a scheduled task that is calling a script, that would do the same.

Thank You, I'll try this.
