How to install

pip install moesiftornado

How to use

from moesiftornado import MoesifMiddleware
import tornado.web
import json

class MainHandler(tornado.web.RequestHandler):
    def get(self):
        self.write(json.dumps({ "msg": "Hello, world" }))

moesif_config = {
    'APPLICATION_ID': 'Your Moesif Application id',
    'LOG_BODY': True,
    # ... For other options see below.
}

# Create a moesif middleware
middleware = MoesifMiddleware(moesif_config)
# Set the log_function to middleware.log_event to log the events to Moesif
application = tornado.web.Application([(r"/", MainHandler)], log_function=middleware.log_event)

Your Moesif Application Id can be found in the Moesif Portal. After signing up for a Moesif account, your Moesif Application Id will be displayed during the onboarding steps.

You can always find your Moesif Application Id at any time by logging into the Moesif Portal, click on the top right menu, and then clicking API Keys.

Configuration options

APPLICATION_ID

(required), string, is obtained via your Moesif Account, this is required.

SKIP

(optional) (handler) => boolean, a function that takes a Request handler, and returns true if you want to skip this particular event.

IDENTIFY_USER

(optional, but highly recommended) (handler) => string, a function that takes a Request handler, and returns a string that is the user id used by your system. While Moesif tries to identify users automatically, but different frameworks and your implementation might be very different, it would be helpful and much more accurate to provide this function.

IDENTIFY_COMPANY

(optional) (handler) => string, a function that takes a Request handler, and returns a string that is the company id for this event.

GET_METADATA

(optional) (handler) => dictionary, a function that takes a Request handler, and returns a dictionary (must be able to be encoded into JSON). This allows your to associate this event with custom metadata. For example, you may want to save a VM instance_id, a trace_id, or a tenant_id with the request.

GET_SESSION_TOKEN

(optional) (handler) => string, a function that takes a Request handler, and returns a string that is the session token for this event. Again, Moesif tries to get the session token automatically, but if you setup is very different from standard, this function will be very helpful for tying events together, and help you replay the events.

MASK_EVENT_MODEL

(optional) (EventModel) => EventModel, a function that takes an EventModel and returns an EventModel with desired data removed. The return value must be a valid EventModel required by Moesif data ingestion API. For details regarding EventModel please see the Moesif Python API Documentation.

DEBUG

(optional) boolean, a flag to see debugging messages.

LOG_BODY

(optional) boolean, default True, Set to False to remove logging request and response body.

BATCH_SIZE

(optional) int, default 25, Maximum batch size when sending to Moesif.

Example:

from moesiftornado import MoesifMiddleware
import tornado.web

def identify_user(handler):
    # Your custom code that returns a user id string
    return "my_user_id"

def identify_company(handler):
    # Your custom code that returns a company id string
    return "my_company_id"

def get_token(handler):
    # Your custom code that returns a string for session/API token
    return "XXXXXXXXXXXXXX"

def should_skip(handler):
    # Your custom code that returns true to skip logging
    return "health/probe" in handler.request.full_url()

def mask_event(event_model):
    # Your custom code to change or remove any sensitive fields
    if 'password' in event_model.request.body:
        event_model.request.body['password'] = None
    return event_model

def get_metadata(handler):
    return {
        'datacenter': 'westus',
        'deployment_version': 'v1.2.3',
    }

moesif_config = {
    'APPLICATION_ID': 'Your Moesif Application Id',
    'LOG_BODY': True,

    'GET_METADATA': get_metadata,
}

middleware = MoesifMiddleware(moesif_config)
application = tornado.web.Application([(r"/", MainHandler)], log_function=middleware.log_event)

Update User

Update A Single User

Create or update a user profile in Moesif. The metadata field can be any customer demographic or other info you want to store. Only the user_id field is required. For details, visit the Python API Reference.

from moesiftornado import MoesifMiddleware
middleware = MoesifMiddleware(moesif_config)

# Only user_id is required.
# Campaign object is optional, but useful if you want to track ROI of acquisition channels
# See https://www.moesif.com/docs/api#users for campaign schema
# metadata can be any custom object
user_profile = {
  'user_id': '12345',
  'company_id': '67890', # If set, associate user with a company object
  'campaign': {
    'utm_source': 'google',
    'utm_medium': 'cpc', 
    'utm_campaign': 'adwords',
    'utm_term': 'api+tooling',

}

middleware.update_user(user_profile)

userA = {
  'user_id': '12345',
