-This example demonstrates how to obtain uniform metrics, logs, traces across different services using Istio Mixer and Istio sidecar.
-
-## Overview
-
-Deploying a microservice-based application in an Istio service mesh allows one
-to externally control service monitoring and tracing, request (version) routing, resiliency testing,
-security and policy enforcement, etc., in a consistent way across the services,
-for the application as a whole.
-
-In this example, we will use the [Bookinfo sample application](/docs/examples/bookinfo/)
-to show how operators can obtain uniform metrics and traces from running
-applications involving diverse language frameworks without relying on
-developers to manually instrument their applications.
-
-## Before you begin
-
-* Install the Istio control plane by following the instructions
-  corresponding to your platform [installation guide](/docs/setup/).
-
-* Run the Bookinfo sample application by following the applicable
-  [application deployment instructions](/docs/examples/bookinfo/#deploying-the-application).
-
-## Tasks
-
-1. [Collecting metrics](/docs/tasks/telemetry/metrics-logs/)
-   This task will configure Mixer to collect a uniform set of metrics
-   across all services in the Bookinfo application.
-
-1. [Querying metrics](/docs/tasks/telemetry/querying-metrics/)
-   This task installs the Prometheus add-on for metrics collection and
-   demonstrates querying a configured Prometheus server for Istio metrics.
-
-1. [Distributed tracing](/docs/tasks/telemetry/distributed-tracing/)
-   We will now use Istio to trace how requests are flowing across services
-   in the application. Distributed tracing speeds up troubleshooting by
-   allowing developers to quickly understand how different services
-   contribute to the overall end-user perceived latency. In addition, it
-   can be a valuable tool to diagnosis and troubleshooting in distributed
-   applications.
-
-1. [Using the Istio Dashboard](/docs/tasks/telemetry/using-istio-dashboard/)
-   This task installs the Grafana add-on with a preconfigured dashboard
-   for monitoring mesh traffic.
-
-## Cleanup
-
-When you're finished experimenting with the Bookinfo sample, you can
-uninstall it by following the
-[Bookinfo cleanup instructions](/docs/examples/bookinfo/#cleanup)
-corresponding to your environment.
