Is there anything special in your setup? For example, are you using the Logstash or Kafka outputs? Are you using a load balancer in front of the APM Servers? Have you changed index pattern, generated custom templates, changed agent configuration etc.
Description of the problem including expected versus actual behavior. Please include screenshots (if relevant) : Hello, I'm running Rails 5.0 and was wondering if there is a way to disable the sending of metrics for specific transactions. For example, my app has a health controller for health checks, and I don't want agents to send metrics for this endpoint to the apm server. Can I do this? Is it possible to simply add a before_action callback on the health controller that ends the current transaction? Thanks!
