insanic-incendiary 0.2.0

tracing for insanic

Incendiary

A Tracing extension for Insanic that integrates AWS X-Ray.

Why?

Tracing is needed in any micro service architecture, and this plugin traces requests received and traces any requests with Insanic’s interservice’s communications and sends it’s traced information to AWS X-Ray.

You might be asking why this package is called incendiary. In the military there, rifles and machine guns are usually loaded with tracer rounds every 3-4 rounds which help adjust for aim. And tracer rounds usually have a mild “incendiary” effect to help with visibility.

Tracing is a distributed system also samples(every X request) to help with overall visibility of the system.

Features

• Tracing with AWS X-ray.

• Creates a segment when Insanic receives a request.

• End the segment before return the response.

• Sampling configuration

• Starts and ends subsegments for interservice requests with Insanic.

• Capture other parts of your code.

Installation

Prerequisites for using:

• python >= 3.6

• Local running instance of AWS X-Ray Daemon. (Running instructions can be found here)

• AWS Credentials (if you want to actually send data to AWS-Ray)

To install:

pip install insanic-incendiary

Basic Usage

Basic usage is actually quite simple. You should be able to get it running without any extra configurations.

To Initialize

# app.py

...

from insanic import Insanic
from incendiary import Incendiary

app = Insanic("my_app", version="0.1.0")
Incendiary.init_app(app)

Now if you run, you should be able to start tracing.

To Capture

# in_some_module_you_want_to_capture.py

from incendiary import Incendiary

# if async function

@Incendiary.capture_async(name="Name of subsegment")
async def i_want_to_capture_async():
    pass

# if sync function

@Incendiary.capture(name="Name of subsegment")
def i_want_to_capture():
    pass

These functions will be its own subsegments in X-Ray.

Warning

You should try and avoid capturing in a production environment, because capturing has a performance impact.
