Auto-instrumentation configuration

Since auto-instrumentation aims to get started as quickly as possible, let's see how fast we can generate telemetry with as little code as possible. The following code makes a web request to https://www.cloudnativeobservability.com and prints the HTTP response code:

http_request.py

import requests
url = "https://www.cloudnativeobservability.com"
resp = requests.get(url)
print(resp.status_code)

When running the code, assuming network connectivity is available and the URL we're requesting connects us to a server that is operating normally, we should see 200 printed out:

$ python http_request.py
200

Great, the program works; now it's time to instrument it. The following command uses the opentelemetry-instrument application to wrap the application we created. We will look more closely at the command and its options shortly. For now, run the command:

$ opentelemetry-instrument --traces_exporter console \
