NPM/NetPath alert creation issue

I deployed our new install of NPM/NTA early this week, and now I'm trying to set up alerts for the NetPath Services that I've set up, and while I've got the basic e-mail alerts working, I can't get it to populate some of the variable data.

I have the alert set up to send an e-mail any time the status of the NetPath is not good, it tells me in the subject which path is having issues, and the data that I want to have in the alert e-mails is primarily the response time and packet loss, but that info isn't displaying.

What I have in the e-mail is this:

Current response time: ${N=SwisEntity;M=Probe.Agent.Node.Stats.ResponseTime}

Current Packet loss: ${N=SwisEntity;M=Probe.Agent.Node.Stats.PercentLoss}

What I get is this:

Current response time: ms

Current Packet loss: %

I also threw these into the message to see if any of them would give me what I was looking for, but they didn't:

${N=SwisEntity;M=Probe.Agent.Node.ResponseTime}

${N=SwisEntity;M=Probe.Agent.ResponseTime}

${N=SwisEntity;M=Probe.Agent.Node.PercentLoss}

Does anyone have any ideas why it's not populating the packet loss and response time variables, or if maybe there's some other variable I should be using?

Those SWIS entities you used are node statistis on the Orion Agent machine running NetPath probe. So it has nothing to do with the measurements you saw in NetPath graph.

The SWIS entities that report path packet loss and latency are: Orion.NetPath.Tests.PacketLoss and Orion.NetPath.Tests.Rtt. But I don't think those entities are exposed in web alerting in NetPath v1.

That's a bummer. I don't see anything else that would seem to apply. Hopefully they will get added to the alerting at some point.

Can you share your trigger?

Here is what I have set up for the trigger:

There is a scenario in which I'm not sure that this alerting logic would capture. My employer has WAN failover paths (GRE w/ IPsec) for each of our remote offices. This, of course, is in place in the case BGP adjacency is lost for any reason. Once the holddown timer is exceeded, EIGRP will route all subnets through the tunnel. This would all happen within 2 minutes time. If NetPath is configured to poll at times greater than this interval, the NetPath may remain in the "Good" state the whole time.

There are no event variables available for the NetPath Endpoint Service Assignments or NetPath Probe alerting groups. I'm curious as to if NetPath can be configured to alert if the path to reach the destination has changed.
