Hello, While trying to work with lab 6.4 in the Observability Engineer course, I am trying to replicate the visualization depicted in step 16. Even after starting filebeat/metricbeat and heartbeat on mysql/petclinicclient/server and elasticsearch, I can only get mysql and the petclinic client server to show any data. I assume that would mean that all the beats are not configured? I have been following all the labs and have configured quite a few, but still no data shows up in the TSVB even after 15 minutes. ![image](https://us1.discourse-cdn.com/elastic/original/3X/f/d/fdb3059388b1b547b1fea9bf464fadfb3334be87.png) Am i missing any step where i need to go though all servers and check if each beat is correctly configured to send data to elastic? I have been working on the labs on and off, pausing the strigo workspace. thanks ---

I would check whether or not all the beats have restarted. They do not restart automatically when the strigo environment wakes back up, unfortunately. ---

It would have been good to know the pre-requisites for the lab, especially when we restart Strigo periodically. ---

So, it worked after configuring some beats. ![image](https://us1.discourse-cdn.com/elastic/original/3X/5/d/5df72ad6a44a12a3561a20ff555b56bc429ac015.png) In fact, it would not have worked if I had not completed lab 8.3. Looks like there are some steps needed or the labs need to be re-sequenced. thanks! ---

We will be producing an updated course later this Fall, and will take steps to improve the interoperability of the labs in the on-demand environment. ---
