Retina is a cloud-agnostic, open-source Kubernetes network observability platform that provides a centralized hub for monitoring application health, network health, and security. It provides actionable insights to cluster network administrators, cluster security administrators, and DevOps engineers navigating DevOps, SecOps, and compliance use cases.

Retina collects customizable telemetry, which can be exported to multiple storage options (such as Prometheus, Azure Monitor, and other vendors) and visualized in a variety of ways (like Grafana, Azure Log Analytics, and other vendors).

• eBPF-based Network Observability platform for Kubernetes workloads.
• On-Demand and Configurable.
• Actionable, industry-standard Prometheus metrics.
• Streamlined Packet Captures for deep dives.
• Cloud-agnostic, supporting multiple OS (like Linux, Windows, Azure Linux).

Retina lets you investigate network issues on-demand and continuously monitor your clusters. For scenarios where Retina shines, see the intro docs here

See retina.sh for documentation and examples.

Retina has two major features:

• Metrics
• Captures

Retina can be installed using the Helm chart from GHCR:

# Set the version to a specific version here or get latest version from GitHub API.
VERSION=$( curl -sL https://api.github.com/repos/microsoft/retina/releases/latest | jq -r .name)
helm upgrade --install retina oci://ghcr.io/microsoft/retina/charts/retina \
    --version $VERSION \
		--set image.tag=$VERSION \
		--set operator.tag=$VERSION \
		--set logLevel=info \
		--set enabledPlugin_linux="\[dropreason\,packetforward\,linuxutil\,dns\]"

Set the version and image tag arguments to the desired version, if different.

After Helm install, follow steps in Using Prometheus and Grafana to set up metrics collection and visualization.

The preferred way to install the Retina CLI using Krew.

kubectl krew install retina

Other installation options are documented in CLI Installation.

Verify installation:

$ kubectl retina version
v0.0.4 # or latest version

To quickly start creating a capture:

kubectl retina capture create --name <my-capture> --namespace <my-namespace> --selector <app=my-app>

For further CLI documentation, see Capture with Retina CLI.

Install Retina using Helm:

VERSION=$( curl -sL https://api.github.com/repos/microsoft/retina/releases/latest | jq -r .name)
helm upgrade --install retina oci://ghcr.io/microsoft/retina/charts/retina \
    --version $VERSION \
    --set image.tag=$VERSION \
    --set operator.tag=$VERSION \
    --set image.pullPolicy=Always \
    --set logLevel=info \
    --set os.windows=true \
    --set operator.enabled=true \
    --set operator.enableRetinaEndpoint=true \
    --skip-crds \
    --set enabledPlugin_linux="\[dropreason\,packetforward\,linuxutil\,dns\,packetparser\]"

Then follow steps in Capture CRD for documentation of the CRD and examples for setting up Captures.
