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.

Accessing OpenShift Information

See Kubernetes for more details.

Metrics 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 general Kubernetes information. See Kubernetes for more information. In addition we also collect information about DeploymentConfigs which 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

Health signatures

For each sensor, there is a curated knowledgebase of health signatures that are evaluated continuously against the incoming metrics and are used to raise issues or incidents depending on user impact.

Built-in events trigger issues or incidents based on failing health signatures on entities, and custom events trigger issues or incidents based on the thresholds of an individual metric of any given entity.

For information about the built-in event for the OpenShift sensor, see the Built-in events reference.
