Dashboard Metric Expression Calculation Issue

Hi folks

 

We have AppD running for some services we are monitoring, and I have noticed that on the metric expression calculation, if one of the values I am calculating against is "no data found" the calculation fails completely.

 

My question is this: Is there a way that we can configure the metric to show a zero where no data is found instead of "no data found"?

 

Thanks

 

James

Hi @Chidi.uchegbu,

 

Thanks for giving that a try. If this seems like a bug, I would suggest reaching out to AppD Support by going to https://www.appdynamics.com/support

 

If you do contact support please do share any information that could help this thread out. 


Thanks,

To overcome this issue, we need to set the com.appdynamics.metric.query.metricexpressions.tolerateNull flag to true in ControllerFlagServlet. If you are using a SaaS controller please reach out to AppDynamics support to enable this flag.

 

If you are using On-Prem Controller follow the below steps to enable the flag:

1. Login to <controllerURL>/controller/

2. Use root@system and controller root password for login

3. Look for metricexpressions.tolerateNull field and set it to ‘true’

4. Hit Submit button.
