Monitor OpenShift performance metrics

This text discusses how to monitor an application deployed on OpenShift using Datadog. By adding the Datadog cartridge to all gears, metrics from OpenShift will automatically appear in Datadog, allowing users to create graphs and set up alerts as needed. The text also explains that this cartridge is designed for OpenShift v2 gears but can be used with custom metrics on v3 containers. It highlights the benefits of using Datadog for monitoring, including its ability to collect metrics from various servers in one place, generate alerts when gears misbehave, and correlate performance metrics with events from other systems. The text also provides a step-by-step installation guide for the Datadog cartridge on OpenShift v2 apps.
