This chapter is dependent on the previous chapter. If you haven't already done so, complete the exercises in Chapter 12, Enabling Istio's Policy Controls.

Let's change the directory for the scripts that we will be using in this chapter:

$ cd ~/istio
$ cd scripts/04-telemetry

Make sure that all istio-lab pods show Ready state 2/2:

$ kubectl -n istio-lab get pods

Once done, we're ready to begin!
