Creating a Health Rule condition for total error percentage

[CommunityUser]

Hey all. I'm trying to create a Health Rule to be used for monitoring errors on one of our remote services. I would like for the critical condition to trigger when the error percentage is 100% (see image for the value I'm talking about).  The warning condition would be when the error percentage is >50%.

What condition should I use for this?

Hello Riley,

You can use metrics expression:
https://docs.appdynamics.com/display/PRO44/Configure+Health+Rules

Create a variable epm with metric as SUM of errors / min
Create a variable cpm with metric as  SUM of calls / min 
Use these vars in the expression as {epm}*100/{cpm}

is > 100
