Hi everyone.
1) Is there a way to create thresholds if a event keeps for last n minutes.
For example, alert if a node is down for more than 5 minutes or alert if bandwith is above xxx for more than 10 minutes?

2) I need to check for network interfaces error and create an alert if error on some interface increase, I suppose that I have tu use the option "diff with previous value" do you have any example?

Hi!

1) You can use actions with timers. For example, execute action on node down event with timer set to 5 minutes, and cancel this timer on "node up" event. If node will recover within 5 minute interval, timer will be cancelled and action never executed.

2) Yes, diff will be correct method in this case.

Best regards,
Victor
