Server Manager

How to use

The commands to control the Server Manager are:

• start-server-manager starts the Server Manager in the background
• attach-to-server-manager attaches the console to the Server Manager tmux session allowing to visualize the status of the Server Manager
• Ctrl+B, D detaches the console from the Server Manager tmux session
• kill-all-robot-servers kills all the running Robot Servers and the Server Manager
• kill-server-manager kills the Server Manager
• restart-server-manager kills all the running Robot Servers and the Server Manager and starts the Server Manager in the background

Testing

Start the Server Manager and attach to the session with:

start-server-manager && attach-to-server-manager

Expected output:

2021-XX-XX XX:XX:XX,XXX - serverManager - INFO - Server Manager started at 50100

If you get: start-server-manager: command not found it is most probably because your $PATH is not set correctly, to fix the problem add:

export PATH="/home/<your_username>/.local/bin:$PATH"

to your .bashrc file.
