Monitoring a cloud native platform feature
•
1 like•504 views
This document discusses making application monitoring a native feature of cloud platforms. It describes integrating the Dynatrace application monitoring agent into buildpacks used by Cloud Foundry so it is automatically injected into applications. This would provide full-stack visibility from code to services to infrastructure for Cloud Foundry applications and clusters. The document also discusses deploying the Dynatrace agent to all VMs managed by BOSH to monitor all components of Cloud Foundry deployments.
