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.

DeploymentConfigs

Field Description
Conditions Type, Status, Timestamp, Reason, Message
Labels Key/value pairs
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

Within the OpenShift panel, we provide an overview of DeploymentConfigs: DeploymentConfigs table

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.
