OpenTracing is a single, vendor-neutral, standard mechanism to describe the
behaviour of our distributed systems. It allows developers of application code,
OSS packages and OSS services to instrument their own code.

Before diving into the tutorial, ensure you are familiar with:

OpenTracing Python Tutorial - Lesson 01

Step 1 of 4

Quick Hello World Example

Let's write a simple python program to print "Hello, arg!", where
arg is a command line argument to the program.

Click the below link to open hello.py in the editor.
exercise/hello.py The file is located at
/root/opentracing-tutorial/python/lesson01/exercise

Once the file is opened in the editor, you may copy the below content
into the file (or use the Copy to Editor button):

# simple hello world program

import sys

def say_hello(hello_to):
  hello_str = 'Hello, %s!' % hello_to
  print hello_str

assert len(sys.argv) == 2

hello_to = sys.argv[1]
say_hello(hello_to)

We run the above program with an argument, say Alice,
python2.7 hello.py Alice

We should see the output as:
Hello, Alice!

Let's instrument the above code to illustrate the features of
OpenTracing (an opensource standard for distributed tracing) using
Jaeger (an opensource distributed tracing system). You may also use other
tracing systems, such as, Zipkin, LightStep etc.
