If you want to receive notice that something is down you need to look first at how the Dude looks at the status of a device.
Here is the order of things
1st: Up -> 2nd: unstable -> 3rd: down
So if you want notification when it's unstable put a check next to: up -> unstable
if you want notification when it's down you would put a check next to: unstable -> down
and for when it's back up from down you would put your check next to: down -> up
or for when it back up from unstable put your check next to: unstable -> up
I only look for Status of Down and then back up.
So I only have checks next to
unstable -> down
down -> up
To give you an idea of a standard email notification when something goes down:
Tab: General 1) Create a notification > Type Email 2) if you have set up a default SMTP server in "settings" it will be used, otherwise you can tick the "server" box and provide a different IP address 3) To: Where the notification should be sent to 4) evtl. cc 5) Subject: Feel free to modify but be careful, you can only use the variables that are offered by the system. 6) Body: Same
Tab: Schedule If you want your notification only during specific hours you can "exclude" certain hours by marking them "inactive" - no email will be sent in these times
Tab: Advanced Delay: Specify a delay you want before the email is sent (when you use multiple notifiers you might want it delayed so it arrives in your mailbox last (i.e. on top) Repeat Interval: Send the email again after x seconds Repeat Count: how often to be sent On Status: For a standard notification to let you know that something is down or up just select: down > up unstable > down up > down
Now say OK and apply the notification to where you want it. To a single probe, a device, a network map or global. Note that a device setting overrules a global setting and a probe setting overrules a device setting.
