Daily Data Collection Error

[kamng]

Hi All,

First time using Performance Analytics after taking the PA fundamentals class. While in the dashboard under PA I am trying to use OOTB Performance Analytics widget CMDB Accuracy Ratio %, but I am getting No Data Available. I've checked the dependency assessment and looked at:

[PA CMDB] Daily Data Collection and [PA CMDB] Historic Data Collection and I am getting the error:

Unexpected exception occurred java.lang.NullPointerException

Not sure what needs to be done

Thanks

It could be that your breakdown collection are hitting one of the limits set on the data collector properties

https://docs.servicenow.com/bundle/madrid-performance-analytics-and-reporting/page/use/performance-a...

If so, you can increase the limits, thought the default settings are mean to discourage a high volumen of score collections. Maybe reducing the breakdown matrix combinations can help.
