Alert for UnDP Transform

I'm trying to configure an alert to tell me when our UPS load goes over a certain percent. We have many UPS's that are different manufacturers and sizes and I don't want to write an alert for each one.

So, I poll them all for their maximum load capacity and then I poll them for their current load. I wrote a transform to calculate their load percentage.

I want to write an alert to fire when the load percentage goes over 80 percent and then another for 90 percent.

So I have an alert the fires when all apply:

Poller Name is equal to LoadPercent

Rate is great than or equal to 80

I'm not sure if "Rate" is the correct attribute, so during testing I set the alert action to send me an email and tell me the name of the poller and the rate to verify I'm using the correct data.

The email message is configured as such:

CustomPollers.Description = ${CustomPollers.Description}

AssignmentName = ${AssignmentName}

CustomPollerStatus.Rate = ${CustomPollerStatus.Rate}

CustomPollerStatus.Status = ${CustomPollerStatus.Status}

When I test fire the alert, the email comes through looking like:

CustomPollers.Description = The indication of the capacity remaing in the UPS system's batteries.

AssignmentName = BatteryStatus

CustomPollerStatus.Rate = 2

CustomPollerStatus.Status = batteryNormal(2)

As you can see, it's not pulling any information about my Transform poller, but rather a random poller or maybe the first custom poller assigned to that node? Because of this, I'm not confident that I'm checking the correct poller to fire the alert, nor do I know how to make the alert email relevant to the alert.

I've written lots of alerts, but never for a custom poller.

Any advice?

Update:

I've created another alert based on a regular UnDP poller (as opposed to a UnDP Transform Poller as mentioned above) so I know it can be real easy. I have a poller now that is checking on BGP peers and prefixes and am alerting if the number of prefixes drops below a certain amount.

We've had instances were our MPLS provider will break their BGP but we don't get alerted because the circuit stays up and therefore our interface alert never fires. And since we have redundant circuits to all our sites the node alert never fires because we can still contact it through the redundant circuit.

Anyway, the alert looks like:

Poller Name is equal to cbgpPeerAcceptedPrefixes

Total is less than or equal to 20

And the message that goes out:

Lost BGP Routes on ${NodeName}

${AssignmentName} is ${CustomPollerStatus.Total}

The message I get when I test fire the alert:

Lost BGP Routes on PHXWanR04

cbgpPeerAcceptedPrefixes on PHXWanR04 is 160 (normal amount of prefixes during the test)

Still looking for help on how to make that Transform alert work properly, though.

Is anyone alerting on Transform results?

PS - The weirdness about the UnDP poller listed in this message is that the tabular view added to the website node view ends up showing the name of the object (PHXWanR04), then status (weird) which always seems to be 0, and the Last Polled. Why wouldn't it display the value (Total) that is returned by the poller (a value between 160 and 330 depending on the router being polled).

Really?

Nothing?

No one is doing alerts on Transform pollers? I guess I'm going to have to just configure a bunch of dumb'd down alerts for each UPS.

Well I'm trying to do an alert on a custom transform and failing miserably as well. My transform simply divides one customer poller by another and multiplies by 100 to get a value in percent. Basically I'm trying to guard against too many PoE devices sucking the life out of a closet switch.

The transform is working fine and I'm able to graph percent utilization on the node status page but no luck on the alert. I've tried using all of the variables and none of them look even close to the value of 60.5%.

Here's the email template:

Timestamp = ${CustomPollerStatus.DateTime}
Percent Utilization = ${CustomPollerStatus.Total as Numeric}
===
${CustomPollerStatus.CustomPollerAssignmentID}
${CustomPollerStatus.Rate as Numeric}
${CustomPollerStatus.RawStatus as Numeric}
${CustomPollerStatus.RowID as Numeric}
${CustomPollerStatus.Status as Numeric}
${CustomPollerStatus.Total as Numeric}
===

And here's the result:

Timestamp = 9/16/2009 8:16:00 PM
Percent Utilization =
===

Can you share with me the UnDP and what you do to obtain the number of BGP prefixes? I need to setup a poller for all my WAN interfaces in my MPLS cloud as we just had a situation where BGP was no but receiving no routes.

Any and all infor would be appreciated.

Off topic from the original post, which I think I finally just gave up on, but to get BGP prefixes, poll for OID 1.3.6.1.4.1.9.9.187.1.2.4.1.1, name it cbgpPeerAcceptedPrefixes and set the MIB value type to Raw Value.

The create an alert where the trigger condition is:

"Poller Name is equal to cbgpPeerAcceptedPrefixes" and

"Total is less than or equal to 20"

and the alert will fire when you have less than 21 prefixes on any of the BGP routers to which you assign the poller and alert.

I see this is old, but that you never got it resolved.

In this situation I would first of all check the database (use the Orion Database Manager if you havent got SQL Studio) and check the table (Sorry not got the DB table names to hand) with the Poller Status and see what column the value you are looking for (% from the Transform in your case) is stored in. Specify this from the Variable list in the Alert.

I seem to remember there was an issue with filters on transformed values working in alerts previously, so maybe this has already been resolved for you.
