Sum of Duration fields

Maria DeLaCruz

Hello,

I am very new to Performance Analytics and need some help.   We tried creating a PA Indicator to get the sum of a duration field of a few thousand records.   For some reason, the dashboard shows 0 for the sum.   Is it possible to add duration fields?   In the screenshot below, the highlighted item is what we want to add up.

Thanks,

Maria

Hi Maria,



a duration field is actually a datetime field so you can not simply sum the values from that column but you first need to translate those values to numeric values. In Performance Analytics you can create a script (Data Collector > Scripts) that is called during score collection. For example, a script on the incident table for the field Duration (with a column name of calendar_duration, use that in the actual script) could look like:


        Calendar Duration _ ServiceNow 2016-04-01 22-31-24.png


Durations are stored as offset in milliseconds from Jan 1, 1970; hence the division by (60 * 60 * 1000) to retrieve a number in hours.



Next the script is used when defining the indicator. For example an indicator that retrieves the Average duration of resolved incidents, looks like:



        Average calendar duration of resolved incidents _ ServiceNow 2016-04-01 22-47-32.png



The result looks like:


        ServiceNow 2016-04-01 22-49-56.png



Hope this helps.



Cheers, Pieter

In your script record, on the source section, add the field Duration:

He added that to the fields under Source section and tried multiple times, but he said it was not working. Not sure whether it was solved or not.

no it was not working

pieter.goris  any new script u have as I think its not working as I am doing for mi_duration field in incident_metric

Okay, so what does your script look like?

What is the column name you are using in the script?

Can you post a screenshot of your script record, similar to the the screenshot I posted 8 days ago?
