 ## How to upgrade the Container insights agent
 
-Container insights uses a containerized version of the Log Analytics agent for Linux. When a new version of the agent is released, the agent is automatically upgraded on your managed Kubernetes clusters hosted on Azure Kubernetes Service (AKS) and Azure Red Hat OpenShift version 3.x. For a [hybrid Kubernetes cluster](container-insights-hybrid-setup.md) and Azure Red Hat OpenShift version 4.x, the agent is not managed, and you need to manually upgrade the agent.

 ## How to disable environment variable collection on a container
 
 Container insights collects environmental variables from the containers running in a pod and presents them in the property pane of the selected container in the **Containers** view. You can control this behavior by disabling collection for a specific container either during deployment of the Kubernetes cluster, or after by setting the environment variable *AZMON_COLLECT_ENV*. This feature is available from the agent version – ciprod11292018 and higher.
