How to check if all the server listed is actually being used when running a build using distcc

I'm first time using distcc and have gone through the Readme.

To setup I have three Ubuntu Servers: Master and Client:

As per the readme it sound like we need to install them on all theree machines. which i have completed. https://github.com/distcc/distcc/blob/master/INSTALL

Ran the command on all three servers:

sudo apt-get install gcc make python3 python3-dev libiberty-dev

./autogen.sh ./configure make install

They completed without any errors.

Create ssh keys across the three machines and added then to the authorized host section. Did a ssh and confirmed they are able to login from the master to the Agent systems without any password

Now from the Master Server i ran the below pointing two the two clients:

Export DISTCC_POTENTIAL_HOSTS='localhost 172.31.33.11 172.31.37.109'

Created a hello world make file:

    #.DEFAULT_GOAL := generate
    .PHONY: all say_hello generate clean

    all: say_hello generate

    say_hello:
            @echo "Hello World"

    generate:
            @echo "Creating empty text files..."
            touch file-{1..10}.txt

    clean:
            @echo "Cleaning up....."
            rm -f *.txt

Ran a build using the below command

 make
 Hello World
 Creating empty text files...
 touch file-{1..10}.txt
 root@ip-172-31-24-96:/data/helloworls#

So here it does look to have worked as expected.

Ran the command as specified in the documentation:

pump make -j40 CC="distcc gcc" --debug

Question:

1> How do we really know that the two client servers have been used during this build
2> Is setting the client servers same as that of the master, If no is there a difference
3> How do we see the UI distcc Monitor
4> How can i join a range of machines which does not have DistCC installed

Thank you

To monitor distcc, you can use distccmon-text on the client that is initiating the build. This will output the current status of the jobs in distcc.

To monitor permanently you can use watch -n 1 distccmon-text to get the status updated every second.

I haven't used the gui application distccmon myself. But I've seen screenshots. That should be an alternative as well, if you have a GUI available on that system.
