Materials for my talks/articles on Python monitoring



Playing with the demos

I recommend using a VM to play with the demos. This repo ships with a Vagrantfile for installing Ubuntu 16.04. Please install Vagrant for your operating system and then:

VM Setup on Windows 10 with Hyper-V

You will need to open a powershell session as Adminstrator and do the following from a clone of the git repository:

C:\> ~\work\\amitsaha\python-monitoring-talk [master ≡]> vagrant up --provider=hyperv
Bringing machine 'default' up with 'hyperv' provider...
==> default: Verifying Hyper-V is enabled...
==> default: Importing a Hyper-V instance
    default: Please choose a switch to attach to your Hyper-V instance.
    default: If none of these are appropriate, please open the Hyper-V manager
    default: to create a new virtual switch.
    default: 1) Default Switch
    default: 2) nat
    default: 3) minikube-virtualswitch
    default: What switch would you like to use? 1
    default: Cloning virtual hard drive...
    default: Creating and registering the VM...
    default: Setting VM Integration Services
    default: Successfully imported a VM with name: ubuntu-18.04-amd64_1
==> default: Starting the machine...
==> default: Waiting for the machine to report its IP address...
    default: Timeout: 120 seconds

Then, we will ssh into the VM using:

C:\> ~\work\\amitsaha\python-monitoring-talk [master ≡]> vagrant ssh

VM Setup on Windows/Linux/OS X - VirtualBox

$ vagrant up
$ vagrant ssh

Now, that we are in the VM, the /vagrant directory has a copy of the entire repository from where you can play with the demos:

$ cd /vagrant
$ ls
demo1  LICENSE                 prometheus  scripts  statsd             Vagrantfile
demo2  opensource-com-article   slides   statsd_prometheus


Each demo directory above has a README explaining the instructions of playing with the demo. In general, to access a network port running in the virtual machine, use the following address in your browser:


If it doesn't work, please file an issue with OS + VM details.

Miscellaneous notes

Docker tips

Rebuild an image:

$ sudo docker-compose -f docker-compose.yml build

If you see errors such as:

ERROR: for webapp Cannot create container for service webapp: Conflict. The container name "/webapp" is already in use by container "2e452aa1622b053fe33c6fe508ddce3f207e8a8c7446564f86e6f31c2d81466c". You have to remove (or rename) that container to be able to reuse that name.

You can do:

$ sudo docker rm webapp

ab tips

Make 100 requests with a concurrency of 3:

$ ab -n 100 -c 3 http://localhost:5000/test/
