Health Rules

Why do I see consistent false alerts; logs display an error  'Error sending metrics'?

This happens when you configure a highly sensitive condition for a health rule.

When you define a very small evaluation time frame (for example, 3 mins) for a health rule condition, few configured metrics may fail to report data during the short time frame due to reasons such as network errors. This may not be the norm, however, alerts are triggered even if a single data point is not reported leading to consistent false alerts.

AppDynamics recommends that you configure a higher time frame to evaluate a health rule condition.
