This document shows how you can use calculated expressions to identify (and alert on) missing data. This recipe is part of the Calculated Measurements Cookbook .
I like this idea!
What considerations/limitations/standards are there to using this methodology for data presence? For example:
Nice one! Only gotcha that I could see is with the current handling if the interval size changes. Otherwise, a nice little metric!
I would also caution against setting the alert to 0, as timing of data coming in could easily lead to spurious results (lots of 1 interval missing as the last interval hasnt made it in before the alert is run).
Martin Mokry do you know if it'd be possible to show also how many datapoints are estimated? Don't know if the calculations engine has access to that information
Hi Adria Casas, Im not sure if there is a way in PAM, but Im thinking it might not as that information is stored in EEM. That said Shaun Hope is working on a Data Quality 'table' that is able to show you how many data points are estimated. It will likely be outside of PAM for starters, but over time may end up with some sort of user interface.
This is exactly the case, thanks Kim!
Adria Casas we know that customers want to see the estimated data marked clearly in PAM, and expect to introduce something like that in the near future. No specific timeline has been set though.
