Installing the Instana agent in Openshift
The Agent Setup Quick Start for Openshift describes how to install the Instana agent into your cluster in a production-ready configuration.
Sensor Data Collection
Once the agent has been deployed to your cluster, the sensor will report detailed data about the cluster and the resources deployed into it. Instana will collect the same information from the OpenShift cluster that our Kubernetes support collects (cluster, nodes, deployments, pods), and in addition also collect information about DeploymentConfigs that are specific to OpenShift clusters.
|Conditions||Type, Status, Timestamp, Reason, Message|
|CPU Requests||Aggregated CPU requests of all running containers of this DeploymentConfig|
|CPU Limits||Aggregated CPU limits of all running containers of this DeploymentConfig|
|Memory Requests||Aggregated memory requests of all running containers of this DeploymentConfig|
|Memory Limits||Aggregated memory limits of all running containers of this DeploymentConfig|
|Pods Requested||Available / Desired Pods|
|Pods Statuses||Pending / Unscheduled / Unready Pods|
|Pending phase duration||In most cases can be interpreted as rollout duration|
Built-in Health Rules
There is a built-in health rule that will trigger an issue for a
DeploymentConfig entity if the number of available replicas is less than desired replicas.
