This project extends the Application Insights API surface to support Python.
`Application Insights
<http://azure.microsoft.com/services/application-insights/>`_ is a service that
allows developers to keep their application available, performing and
succeeding. This Python module will allow you to send telemetry of various kinds
(event, trace, exception, etc.) to the Application Insights service where they
can be visualized in the Azure Portal. A link to the Application Insights API
documentation can be found `here
<https://brennerm.github.io/python-appinsights/>`_.
This project is not officially supported and not recommended for high load
production use. The project is open source and welcomes contributions.
Requirements
------------
Python >=2.7 and Python >=3.4 are currently supported by this module.
Installation
------------
To install the latest release you can use `pip <http://www.pip-installer.org/>`_.
::
$ pip install appinsights
Documentation
-------------
Please see https://brennerm.github.io/python-appinsights/ for full documentation.
Usage
-----
Once installed, you can send telemetry to Application Insights. Here are a few samples.
**Note**: before you can send data to you will need an instrumentation key. Please see the `Getting an Application Insights Instrumentation Key <https://github.com/Microsoft/AppInsights-Home/wiki#getting-an-application-insights-instrumentation-key>`_ section for more information.
**Sending a simple event telemetry item**
.. code:: python
from applicationinsights import TelemetryClient
tc = TelemetryClient('<YOUR INSTRUMENTATION KEY GOES HERE>')
tc.track_event('Test event')
tc.flush()
**Sending an event telemetry item with custom properties and measurements**
.. code:: python
from applicationinsights import TelemetryClient
tc = TelemetryClient('<YOUR INSTRUMENTATION KEY GOES HERE>')
tc.track_event('Test event', { 'foo': 'bar' }, { 'baz': 42 })
tc.flush()
**Sending a trace telemetry item with custom properties**
.. code:: python
from applicationinsights import TelemetryClient
tc = TelemetryClient('<YOUR INSTRUMENTATION KEY GOES HERE>')
tc.track_trace('Test trace', { 'foo': 'bar' })
tc.flush()
**Sending a metric telemetry item**
.. code:: python
from applicationinsights import TelemetryClient
tc = TelemetryClient('<YOUR INSTRUMENTATION KEY GOES HERE>')
tc.track_metric('My Metric', 42)
tc.flush()
**Sending an availability telemetry item**
.. code:: python
from applicationinsights import TelemetryClient
tc = TelemetryClient('<YOUR INSTRUMENTATION KEY GOES HERE>')
tc.track_availability('My Service', 250, True, "West Europe")
tc.flush()
**Sending an exception telemetry item with custom properties and measurements**
.. code:: python
import sys
from applicationinsights import TelemetryClient
tc = TelemetryClient('<YOUR INSTRUMENTATION KEY GOES HERE>')
try:
raise Exception('blah')
except:
tc.track_exception()
try:
raise Exception("blah")
except:
tc.track_exception(*sys.exc_info(), properties={ 'foo': 'bar' }, measurements={ 'x': 42 })
tc.flush()
**Configuring context for a telemetry client instance**
.. code:: python
from applicationinsights import TelemetryClient
tc = TelemetryClient('<YOUR INSTRUMENTATION KEY GOES HERE>')
tc.context.application.ver = '1.2.3'
tc.context.device.id = 'My current device'
tc.context.device.oem_name = 'Asus'
tc.context.device.model = 'X31A'
tc.context.device.type = "Other"
tc.context.user.id = 'santa@northpole.net'
tc.context.properties['my_property'] = 'my_value'
tc.track_trace('My trace with context')
tc.flush()
**Establishing correlation between telemetry objects**
context field called operation_id can be set to associate telemetry items.
Since operation_id is being set as a property of telemetry client, the client shouldn't be reused in parallel threads as it might lead to concurrency issues.
.. code:: python
tc = TelemetryClient(instrumentation_key=instrumentation_key)
tc.context.operation.id = <operation_id>
tc.track_trace('Test trace')
tc.flush()
**Configuring channel related properties**
.. code:: python
from applicationinsights import TelemetryClient
tc = TelemetryClient('<YOUR INSTRUMENTATION KEY GOES HERE>')
# flush telemetry every 30 seconds (assuming we don't hit max_queue_item_count first)
tc.channel.sender.send_interval_in_milliseconds = 30 * 1000
# flush telemetry if we have 10 or more telemetry items in our queue
tc.channel.queue.max_queue_length = 10
**Configuring TelemetryProcessor**
.. code:: python
from applicationinsights import TelemetryClient
def process(data, context):
data.properties["NEW_PROP"] = "MYPROP" # Add property
context.user.id = "MYID" # Change ID
return True # Not filtered
tc = TelemetryClient('<YOUR INSTRUMENTATION KEY GOES HERE>')
tc.add_telemetry_processor(process)
**Basic logging configuration (first option)**
.. code:: python
import logging
from applicationinsights.logging import enable
# set up logging
enable('<YOUR INSTRUMENTATION KEY GOES HERE>')
# log something (this will be sent to the Application Insights service as a trace)
logging.info('This is a message')
# logging shutdown will cause a flush of all un-sent telemetry items
logging.shutdown()
**Basic logging configuration (second option)**
.. code:: python
import logging
from applicationinsights.logging import LoggingHandler
# set up logging
handler = LoggingHandler('<YOUR INSTRUMENTATION KEY GOES HERE>')
logging.basicConfig(handlers=[ handler ], format='%(levelname)s: %(message)s', level=logging.DEBUG)
# log something (this will be sent to the Application Insights service as a trace)
logging.debug('This is a message')
try:
raise Exception('Some exception')
except:
# this will send an exception to the Application Insights service
logging.exception('Code went boom!')
# logging shutdown will cause a flush of all un-sent telemetry items
# alternatively flush manually via handler.flush()
logging.shutdown()
**Advanced logging configuration**
.. code:: python
import logging
from applicationinsights import channel
from applicationinsights.logging import LoggingHandler
# set up channel with context
telemetry_channel = channel.TelemetryChannel()
telemetry_channel.context.application.ver = '1.2.3'
telemetry_channel.context.properties['my_property'] = 'my_value'
# set up logging
handler = LoggingHandler('<YOUR INSTRUMENTATION KEY GOES HERE>', telemetry_channel=telemetry_channel)
handler.setLevel(logging.DEBUG)
handler.setFormatter(logging.Formatter('%(levelname)s: %(message)s'))
my_logger = logging.getLogger('simple_logger')
my_logger.setLevel(logging.DEBUG)
my_logger.addHandler(handler)
# log something (this will be sent to the Application Insights service as a trace)
my_logger.debug('This is a message')
# logging shutdown will cause a flush of all un-sent telemetry items
# alternatively flush manually via handler.flush()
logging.shutdown()
**Logging unhandled exceptions**
.. code:: python
from applicationinsights.exceptions import enable
# set up exception capture
enable('<YOUR INSTRUMENTATION KEY GOES HERE>')
# raise an exception (this will be sent to the Application Insights service as an exception telemetry object)
raise Exception('Boom!')
# exceptions will cause a flush of all un-sent telemetry items
**Logging unhandled exceptions with context**
.. code:: python
from applicationinsights import channel
from applicationinsights.exceptions import enable
# set up channel with context
telemetry_channel = channel.TelemetryChannel()
telemetry_channel.context.application.ver = '1.2.3'
telemetry_channel.context.properties['my_property'] = 'my_value'
# set up exception capture
enable('<YOUR INSTRUMENTATION KEY GOES HERE>', telemetry_channel=telemetry_channel)
# raise an exception (this will be sent to the Application Insights service as an exception telemetry object)
raise Exception('Boom!')
# exceptions will cause a flush of all un-sent telemetry items
**Track dependency telemetry for HTTP requests with requests**
.. code:: python
from applicationinsights.client import enable_for_requests
import requests
enable_for_requests('<YOUR INSTRUMENTATION KEY GOES HERE>')
requests.get("https://www.python.org/")
# a dependency telemetry will be sent to the Application Insights service
**Track dependency telemetry for HTTP requests with urllib**
.. code:: python
from applicationinsights.client import enable_for_urllib
import urllib.requests
enable_for_urllib('<YOUR INSTRUMENTATION KEY GOES HERE>')
urllib.request.urlopen("https://www.python.org/")
# a dependency telemetry will be sent to the Application Insights service
**Track dependency telemetry for HTTP requests with urllib2**
.. code:: python
from applicationinsights.client import enable_for_urllib2
import urllib2
enable_for_urllib2('<YOUR INSTRUMENTATION KEY GOES HERE>')
urllib2.urlopen("https://www.python.org/")
# a dependency telemetry will be sent to the Application Insights service
**Track dependency telemetry for HTTP requests with urllib3**
.. code:: python
from applicationinsights.client import enable_for_urllib3
import urllib3.requests
enable_for_urllib3('<YOUR INSTRUMENTATION KEY GOES HERE>')
urllib3.PoolManager().request("GET", "https://www.python.org/")
# a dependency telemetry will be sent to the Application Insights service
**Integrating with Flask**
.. code:: python
from flask import Flask
from applicationinsights.flask.ext import AppInsights
# instantiate the Flask application
app = Flask(__name__)
app.config['APPINSIGHTS_INSTRUMENTATIONKEY'] = '<YOUR INSTRUMENTATION KEY GOES HERE>'
# log requests, traces and exceptions to the Application Insights service
appinsights = AppInsights(app)
# define a simple route
@app.route('/')
def hello_world():
# the following message will be sent to the Flask log as well as Application Insights
app.logger.info('Hello World route was called')
return 'Hello World!'
# run the application
if __name__ == '__main__':
app.run()
**Integrating with Django**
Place the following in your `settings.py` file:
.. code:: python
# If on Django < 1.10
MIDDLEWARE_CLASSES = [
# ... or whatever is below for you ...
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
# ... or whatever is above for you ...
'applicationinsights.django.ApplicationInsightsMiddleware', # Add this middleware to the end
]
# If on Django >= 1.10
MIDDLEWARE = [
# ... or whatever is below for you ...
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
# ... or whatever is above for you ...
'applicationinsights.django.ApplicationInsightsMiddleware', # Add this middleware to the end
]
APPLICATION_INSIGHTS = {
# (required) Your Application Insights instrumentation key
'ikey': "00000000-0000-0000-0000-000000000000",
# (optional) By default, request names are logged as the request method
# and relative path of the URL. To log the fully-qualified view names
# instead, set this to True. Defaults to False.
'use_view_name': True,
# (optional) To log arguments passed into the views as custom properties,
# set this to True. Defaults to False.
'record_view_arguments': True,
# (optional) Exceptions are logged by default, to disable, set this to False.
'log_exceptions': False,
# (optional) Events are submitted to Application Insights asynchronously.
# send_interval specifies how often the queue is checked for items to submit.
# send_time specifies how long the sender waits for new input before recycling
# the background thread.
'send_interval': 1.0, # Check every second
'send_time': 3.0, # Wait up to 3 seconds for an event
# (optional, uncommon) If you must send to an endpoint other than the
# default endpoint, specify it here:
'endpoint': "https://dc.services.visualstudio.com/v2/track",
}
This will log all requests and exceptions to the instrumentation key
specified in the `APPLICATION_INSIGHTS` setting. In addition, an
`appinsights` property will be placed on each incoming `request` object in
your views. This will have the following properties:
* `client`: This is an instance of the `applicationinsights.TelemetryClient`
type, which will submit telemetry to the same instrumentation key, and
will parent each telemetry item to the current request.
* `request`: This is the `applicationinsights.channel.contracts.RequestData`
instance for the current request. You can modify properties on this
object during the handling of the current request. It will be submitted
when the request has finished.
* `context`: This is the `applicationinsights.channel.TelemetryContext`
object for the current ApplicationInsights sender.
You can also hook up logging to Django. For example, to log all builtin
Django warnings and errors, use the following logging configuration in
`settings.py`:
.. code:: python
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'handlers': {
# The application insights handler is here
'appinsights': {
'class': 'applicationinsights.django.LoggingHandler',
'level': 'WARNING'
}
},
'loggers': {
'django': {
'handlers': ['appinsights'],
'level': 'WARNING',
'propagate': True,
}
}
}
See Django's `logging documentation <https://docs.djangoproject.com/en/1.11/topics/logging/>`_
for more information.
**Integrating with other web frameworks**
For any other Python web framework that is `WSGI compliant <https://www.python.org/dev/peps/pep-0333/>`_,
the `WSGIApplication <https://github.com/brennerm/python-appinsights/blob/master/applicationinsights/requests/WSGIApplication.py>`_
can be used as a middleware to log requests to Application Insights.
Add common properties to WSGIApplication request events by passing in a dictionary to the WSGIApplication constructor:
.. code:: python
from wsgiref.simple_server import make_server
from pyramid.config import Configurator
from pyramid.response import Response
from applicationinsights.requests import WSGIApplication
# define a simple pyramid route
def hello_world(request):
return Response('Hello World!')
# construct dictionary which contains properties to be included with every request event
common_properties = {
"service": "hello_world_flask_app",
"environment": "production"
}
if __name__ == '__main__':
# create a simple pyramid app
with Configurator() as config:
config.add_route('hello', '/')
config.add_view(hello_world, route_name='hello')
app = config.make_wsgi_app()
# wrap the app in the application insights request logging middleware
app = WSGIApplication('<YOUR INSTRUMENTATION KEY GOES HERE>', app, common_properties=common_properties)
# run the app
server = make_server('0.0.0.0', 6543, app)
server.serve_forever()
