Dual Power Supply Poller - RowID Alert Variable shows both when only one goes down...

Hello,

I have a custom poller for dual power supplies on my F5 Big IP Appliance. The poller works great and displays the data in rows, Row 1 = PS1, Row 2 = PS2. When I write my alert to let me know when the Numeric Status is 0 (down), I want the email alert to let me know which row has that condition.

Basically, my alert says All of the following must be true:

Poller Name = MyPollerName

Numeric Status = 0

Then, my alert action email says:

Power Supply ${CustomPollerStatus.RowID} is DOWN on ${Node.IP_Address}.

PROBLEM:

When I get my alert email, it says: Power Supply 1, 2 is DOWN on x.x.x.x.

This happens when either power supply goes down. I want it to inform me of which Row ID is showing the "0" status so I know which power supply is down.

I've tried two options and neither worked:

First, I tried to create two separate alerts, to match ALL of the conditions stated above and RowID = 1 for the first alert and 2 for the second. This gave me the same "1, 2" output for RowID in the alert email.

Then, I tried to create something similar with ALL of the conditions above and then a nested "any" with either RowID 1 or 2 met. This gave me continuous up alerts every minute and still said "1, 2"

Does anyone know what I'm doing wrong? Please help! Maybe I'm going in the wrong direction by looking for the RowID?

It might be possible to go back and create two separate custom pollers - one for each PS - but it would make my reporting screen too messy.

Thanks for any help!

It looks like your UnDP poller returns a SNMP table value. If so, you're in the same dilemma with those of us that would like to alert on the values in an SNMP table. As far as I know, there's no method to configure a trigger condition so that it's isolated to a specific row.

In your case, what you might be able to do is include the value of the other column (let's call it Status). So you could have something like the following in your e-mail alert:

One of the power supplies in the F5 Big IP is down.

${CustomPollerStatus.RowID}

${CustomPollerStatus.Status}

When you receive the e-mail, hopefully, it'll look something like this:

One of the power supplies in the F5 Big IP is down.

1,2

0,1

This would mean the first power supply is down. Granted, it's not pretty but at least you'll know which power supply triggered the alert.

Thanks for help! This is a good idea. I should have thought to do it this way already!
