Alerts for a tunnel interface

I am trying to set up an alert for a tunnel interface. The Solarwinds server is expected to send an alert when the tunnel interface goes down on the router and stays down for atleast 10 minutes. When I set up the alert, I get a lot of false alerts wherein I find that the tunnel interface is actually not down.

This is the trigger condition that find in the summary:

Trigger Condition:

Edit

Node - Node Name - contains - CR01
And
All child conditions must be satisfied (AND)
Interface - Interface Name - contains - Tunnel12
Interface - Administrative Status - is not equal to - Shutdown
Interface - Operational Status - is equal to - Down

I don't want to get an alert if the tunnel is admin shut down. Could someone help me get this right?

You could configure the router to send traps when interfaces (or better yet tunnels) went down. Might help to validate what's happening from an SNMP perspective. You could even alert off the trap if you didn't trust the polled data. Similarly, you could get syslogs configured such that you would know if an interface changed status. Between traps and syslogs, you will have real-time information to help support or refute the polled information you distrust.

Thanks. The router is configured to send the syslog but that would mean monitoring the syslogs all the time. How can I get an alert notification for this kind of syslog alone? I would like to get an alert email when a log is generated for the status change.

This is very easy to achieve. Just open Syslog Viewer on your server.

Then click on View and select Alerts/Filter Rules

Then click on Add New Rule

In the Message tab you can configure what to look for and in Alert Actions you just configure the Email option.

What you done in your rule looks fine. In the Trigger Condition section, set "Condition must exist for more than 10 minutes"
