[![Build Status](https://travis-ci.com/epsagon/epsagon-python.svg?token=wsveVqcNtBtmq6jpZfSf&branch=master)](https://travis-ci.com/epsagon/epsagon-python) [![Pyversions](https://img.shields.io/pypi/pyversions/epsagon.svg?style=flat)](https://pypi.org/project/epsagon/) [![PypiVersions](https://img.shields.io/pypi/v/epsagon.svg)](https://pypi.org/project/epsagon/) # Epsagon Tracing for Python ![Trace](trace.png) This package provides tracing to Python applications for the collection of distributed tracing and performance metrics in [Epsagon](https://app.epsagon.com/?utm_source=github). ## Contents - [Installation](#installation) - [Usage](#usage) - [Auto-tracing](#auto-tracing) - [Calling the SDK](#calling-the-sdk) - [Tagging Traces](#tagging-traces) - [Measuring Function Duration](#measuring-function-duration) - [Custom Errors](#custom-errors) - [Filter Sensitive Data](#filter-sensitive-data) - [Ignore Endpoints](#ignore-endpoints) - [Trace URL](#trace-url) - [Frameworks](#frameworks) - [Integrations](#integrations) - [Configuration](#configuration) - [Getting Help](#getting-help) - [Opening Issues](#opening-issues) - [License](#license) ## Installation To install Epsagon, simply run: ```sh pip install -U epsagon ``` ## Usage ### Auto-tracing The simplest way to get started is to run your python command with the following environment variable: ```sh export EPSAGON_TOKEN= export EPSAGON_APP_NAME= export EPSAGON_METADATA=FALSE export AUTOWRAPT_BOOTSTRAP=epsagon ``` For example: ```sh export EPSAGON_TOKEN= export EPSAGON_APP_NAME=django-prod export EPSAGON_METADATA=FALSE export AUTOWRAPT_BOOTSTRAP=epsagon python app.py ``` When using inside a `Dockerfile`, you can use `ENV` instead of `export`. You can see the list of auto-tracing [supported frameworks](#frameworks) ### Calling the SDK Another simple alternative is to copy the snippet into your code: ```python import epsagon epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False, ) ``` To run on your framework please refer to [supported frameworks](#frameworks) ### Tagging Traces You can add custom tags to your traces, for easier filtering and aggregations. Add the following call inside your code: ```python epsagon.label('key', 'value') epsagon.label('user_id', user_id) ``` You can also use it to ship custom metrics: ```python epsagon.label('key', 'metric') epsagon.label('items_in_cart', items_in_cart) ``` Valid types are `string`, `bool`, `int` and `float`. In some [frameworks](#frameworks) tagging can be done in different ways. ### Measuring Function Duration You can measure internal functions duration by using the `@epsagon.measure` decorator. For example: ```python @epsagon.measure def heavy_calculation(): # Code... ``` This will ship another metric label to epsagon where the `key=heavy_calculation_duration` and the value will be the actual duration, in seconds. You'll be able to see this label in the trace search, visualize it over time, and generate alerts based on this metric. ### Custom Errors You can set a trace as an error (although handled correctly) to get an alert or just follow it on the dashboard. Add the following call inside your code: ```python try: fail = 1 / 0 except Exception as ex: epsagon.error(ex) # Or manually specify Exception object epsagon.error(Exception('My custom error')) ``` In some [frameworks](#frameworks) custom errors can be declared in different ways. ### Filter Sensitive Data You can pass a list of sensitive properties and hostnames and they will be filtered out from the traces: ```python epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False, keys_to_ignore=['password', 'user_name'], url_patterns_to_ignore=['example.com', 'auth.com'] ) ``` Or specify keys that are allowed: ```python epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False, keys_to_allow=['Request Data', 'Status_Code'], ) ``` The `keys_to_ignore` and `keys_to_allow` properties can contain strings (will perform a loose match, so that `First Name` also matches `first_name`). Also, you can set `url_patterns_to_ignore` to ignore HTTP calls to specific domains. ### Ignore Endpoints You can ignore certain incoming requests by specifying endpoints: ```python epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False, ignored_endpoints=['/healthcheck'], ) ``` ### Trace URL You can get the Epsagon dashboard URL for the current trace, using the following: ```python import epsagon # Inside some endpoint or function print('Epsagon trace URL:', epsagon.get_trace_url()) ``` This can be useful to have an easy access the trace from different platforms. ## Frameworks The following frameworks are supported by Epsagon: |Framework |Supported Version |Auto-tracing Supported | |----------------------------------------|---------------------------|-----------------------------------------------------| |[AWS Lambda](#aws-lambda) |All |

[![Build Status](https://travis-ci.com/epsagon/epsagon-python.svg?token=wsveVqcNtBtmq6jpZfSf&branch=master)](https://travis-ci.com/epsagon/epsagon-python) [![Pyversions](https://img.shields.io/pypi/pyversions/epsagon.svg?style=flat)](https://pypi.org/project/epsagon/) [![PypiVersions](https://img.shields.io/pypi/v/epsagon.svg)](https://pypi.org/project/epsagon/) # Epsagon Tracing for Python ![Trace](trace.png) This package provides tracing to Python applications for the collection of distributed tracing and performance metrics in [Epsagon](https://app.epsagon.com/?utm_source=github). ## Contents - [Installation](#installation) - [Usage](#usage) - [Auto-tracing](#auto-tracing) - [Calling the SDK](#calling-the-sdk) - [Tagging Traces](#tagging-traces) - [Measuring Function Duration](#measuring-function-duration) - [Custom Errors](#custom-errors) - [Filter Sensitive Data](#filter-sensitive-data) - [Ignore Endpoints](#ignore-endpoints) - [Trace URL](#trace-url) - [Frameworks](#frameworks) - [Integrations](#integrations) - [Configuration](#configuration) - [Getting Help](#getting-help) - [Opening Issues](#opening-issues) - [License](#license) ## Installation To install Epsagon, simply run: ```sh pip install -U epsagon ``` ## Usage ### Auto-tracing The simplest way to get started is to run your python command with the following environment variable: ```sh export EPSAGON_TOKEN= export EPSAGON_APP_NAME= export EPSAGON_METADATA=FALSE export AUTOWRAPT_BOOTSTRAP=epsagon ``` For example: ```sh export EPSAGON_TOKEN= export EPSAGON_APP_NAME=django-prod export EPSAGON_METADATA=FALSE export AUTOWRAPT_BOOTSTRAP=epsagon python app.py ``` When using inside a `Dockerfile`, you can use `ENV` instead of `export`. You can see the list of auto-tracing [supported frameworks](#frameworks) ### Calling the SDK Another simple alternative is to copy the snippet into your code: ```python import epsagon epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False, ) ``` To run on your framework please refer to [supported frameworks](#frameworks) ### Tagging Traces You can add custom tags to your traces, for easier filtering and aggregations. Add the following call inside your code: ```python epsagon.label('key', 'value') epsagon.label('user_id', user_id) ``` You can also use it to ship custom metrics: ```python epsagon.label('key', 'metric') epsagon.label('items_in_cart', items_in_cart) ``` Valid types are `string`, `bool`, `int` and `float`. In some [frameworks](#frameworks) tagging can be done in different ways. ### Measuring Function Duration You can measure internal functions duration by using the `@epsagon.measure` decorator. For example: ```python @epsagon.measure def heavy_calculation(): # Code... ``` This will ship another metric label to epsagon where the `key=heavy_calculation_duration` and the value will be the actual duration, in seconds. You'll be able to see this label in the trace search, visualize it over time, and generate alerts based on this metric. ### Custom Errors You can set a trace as an error (although handled correctly) to get an alert or just follow it on the dashboard. Add the following call inside your code: ```python try: fail = 1 / 0 except Exception as ex: epsagon.error(ex) # Or manually specify Exception object epsagon.error(Exception('My custom error')) ``` In some [frameworks](#frameworks) custom errors can be declared in different ways. ### Filter Sensitive Data You can pass a list of sensitive properties and hostnames and they will be filtered out from the traces: ```python epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False, keys_to_ignore=['password', 'user_name'], url_patterns_to_ignore=['example.com', 'auth.com'] ) ``` Or specify keys that are allowed: ```python epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False, keys_to_allow=['Request Data', 'Status_Code'], ) ``` The `keys_to_ignore` and `keys_to_allow` properties can contain strings (will perform a loose match, so that `First Name` also matches `first_name`). Also, you can set `url_patterns_to_ignore` to ignore HTTP calls to specific domains. ### Ignore Endpoints You can ignore certain incoming requests by specifying endpoints: ```python epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False, ignored_endpoints=['/healthcheck'], ) ``` ### Trace URL You can get the Epsagon dashboard URL for the current trace, using the following: ```python import epsagon # Inside some endpoint or function print('Epsagon trace URL:', epsagon.get_trace_url()) ``` This can be useful to have an easy access the trace from different platforms. ## Frameworks The following frameworks are supported by Epsagon: |Framework |Supported Version |Auto-tracing Supported | |----------------------------------------|---------------------------|-----------------------------------------------------| |[AWS Lambda](#aws-lambda) |All |

| ### AWS Lambda Tracing Lambda functions can be done in three methods: 1. Auto-tracing through the Epsagon dashboard. 2. Using the [`serverless-plugin-epsagon`](https://github.com/epsagon/serverless-plugin-epsagon) if you're using The Serverless Framework. 3. Calling the SDK. **Make sure to choose just one of the methods** Calling the SDK is simple: ```python import epsagon epsagon.init( token='', app_name='', metadata_only=False, ) # Wrap your entry point: @epsagon.lambda_wrapper def handle(event, context): # Your code is here ``` ### Step Functions Tracing Step Functions is similar to regular Lambda functions, but the wrapper changes from `lambda_wrapper` to `step_lambda_wrapper`: ```python import epsagon epsagon.init( token='', app_name='', metadata_only=False, ) # Wrap your entry point: @epsagon.step_lambda_wrapper def handle(event, context): # Your code is here ``` ### Django Tracing Django application can be done in two methods: 1. [Auto-tracing](#auto-tracing) using the environment variable. 2. Calling the SDK. Calling the SDK is simple, and should be done in your main `settings.py` file where the application is being initialized: ```python import epsagon epsagon.init( token='', app_name='', metadata_only=False, ) ``` ### Flask Tracing Flask application can be done in two methods: 1. [Auto-tracing](#auto-tracing) using the environment variable. 2. Calling the SDK. Calling the SDK is simple, and should be done in your main `py` file where the application is being initialized: ```python import epsagon epsagon.init( token='', app_name='', metadata_only=False, ) ``` ### Tornado Tracing Tornado application can be done in two methods: 1. [Auto-tracing](#auto-tracing) using the environment variable. 2. Calling the SDK. Calling the SDK is simple, and should be done in your main `py` file where the application is being initialized: ```python import epsagon epsagon.init( token='', app_name='', metadata_only=False, ) ``` ### fastapi Tracing fastapi application can be done in two methods: 1. [Auto-tracing](#auto-tracing) using the environment variable. 2. Calling the SDK. Calling the SDK is simple, and should be done in your main `py` file where the application is being initialized: ```python import epsagon epsagon.init( token='', app_name='', metadata_only=False, ) ``` ### Celery Tracing Celery consumer can be done in two methods: 1. [Auto-tracing](#auto-tracing) using the environment variable. 2. Calling the SDK. Calling the SDK is simple, and should be done in your main `py` file where the consumer is being initialized: ```python import epsagon epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False, ) ``` ### Gunicorn Tracing Gunicorn application can be done in two methods: 1. [Auto-tracing](#auto-tracing) using the environment variable. 2. Calling the SDK. Calling the SDK is simple, and should be done in your main `py` file where the application is being initialized: ```python import epsagon epsagon.init( token='', app_name='', metadata_only=False, ) ``` ### Azure Functions Tracing Azure Functions can be done in the following method: ```python import azure.functions as func import epsagon epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False, ) @epsagon.azure_wrapper def main(req): return func.HttpResponse('Success') ``` ### Chalice Tracing Chalice applications running on Lambda functions can be done by: ```python from chalice import Chalice import epsagon epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False ) app = Chalice(app_name='hello-world') # Your code is here app = epsagon.chalice_wrapper(app) ``` ### Zappa Tracing web applications running on Lambda functions using Zappa can be done by: ```python from zappa.handler import lambda_handler import epsagon epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False ) # Your code is here epsagon_handler = epsagon.lambda_wrapper(lambda_handler) ``` And in your `zappa_settings.json` file include the following: ```json { "lambda_handler": "module.path_to.epsagon_handler" } ``` ### Generic For any tracing, you can simply use the generic Epsagon wrapper using the following example: ```python import epsagon epsagon.init( token='epsagon-token', app_name='app-name-stage', metadata_only=False, ) # Wrap your entry point: @epsagon.python_wrapper(name='my-resource') def main(params): # Your code is here ``` ##
