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"?






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


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

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.
