Hi Rahul,
sorry for the delay again, but it was a long holiday for me. I am not sure what are the "issues with the lab while restarting the process". The lab has been done and tested by many users and you are probably missing something. After you restart the Strigo environment, Elasticsearch and Kibana will be automatically running (similar to how the environment was when you paused it). You can check it by running the following command in the terminal:
ps aux | grep elastic
ps aux | grep kibana
If you want to stop Elasticsearch or Kibana you can run:
kill PID in which PID is the process id number retuned by the command above.
I could reset your lab, but in this case, you would need to redo everything from scratch. If that is what you want, send me your email via private message and I will do so.
