Universal device pollers, can become not that universal?

Hello:

I just want to know how you can show in a map (using Network Atlas) or with UndP, a variable with transform result but using different nodes or sites.

For instance:

I have a variable X for Node A and a variable Y for Node B, I want to show the substraction between X-Y (with Transfom Results) of these two variables but using the information of two particles nodes or sites, instead of only the infomation of one Node itself. I mean the UnDP no that universal.

Thanks I will be waiting for any help.

Universal refers to the ability to poll any OID. What is your use case for manipulating results across 2 different pollers applied to 2 different nodes?

Hello HolyGuacamole:

The thing is that I want to show the Optical Attenuation Power between two sites or nodes, and I have the OID of RX Power and TX power OID, but if I applied the UnDP , it will be show me the information of TX power and RX power of the same Node,specially if I use Undp, because if Universal de Poller. How can I get the value for each node , and do the substraction between them, do i have to use Transform Result or not, How can I do it.??

Thanks for all the help you can give me.

Transforms can use pollers assigned to the same node. So, that's not an option for your use case. Your options would be either custom alerts or reports using Custom SQL or SWQL.

The thread below will help you to derive the necessary SQL statement

Re: Combine two UDPs on a line in a report

you will probably need a SQL IF statement to get both values in the SELECT statement to do the subtraction

Hi Guac:

Thanks for all your answers, last two things, sorry:

a) The substraction is posible only if the Poller send me an integer value, or do you know a function or statement in SQL that can convert the value to a Integer to make the substraction.

b) Related about the IF statement that you are talking about, can you give an example, if is possible.

Thanks

Have a nice day

Hi Guaca:
