Introduction

● What API Manager Offers.

● Collecting & Analysing statistic with BAM.

● Analysing & Visualizing Stats ( Example ).

● Real Time data analysis & alerting with CEP.

*

Collecting Stats with AM

● API manager push statistical data through event streams. ( Request, Response & Fault )

● AM event streams can be configured to push data to CEP & BAM.

● Google Analytics handler can be use to push API usage data to GA.

Configuring APIM with BAM● Official Documentation

○ https://docs.wso2.com/display/AM170/Publishing+API+Runtime+Statistics

● Steps○ Create a database to store api usage statistics. This

database is shared between API manager and BAM ○ Configure WSO2 AM to publish data to WSO2 BAM

using default publisher agent○ Deploy toolbox in BAM to analyze and put

summarized data to shared database

*

Data passed in the default stream

*

View Statistics using API Manager● API Runtime Statics - View API usage from API Publisher and

API Store ○ View information related to api subscriptions, api usage,

usage related to api version, etc from API Publisher○ View application related information○ These charts can be customized

● Monetization of the API usage - View Billing information from API Store ○ Generate bills for API consumers on usage

*

View Usage Data using BAM tools● Published data can be visualized using BAM gadget tools and

reporting tools

○ BAM gadget tools■ Can configure to query stat database in a constant intervals and

display the data in charts.

○ BAM reports■ Can create many types of report such as bar chart report, table

report, pie chart, etc.

Real Time Analysis with CEP

● WSO2 CEP identifies the most meaningful events within the event cloud, analyzes their impacts, and acts on them in real time.

● CEP is extremely high performing and massively scalable.

● It allows you to execute Siddhi queries to process and Analyse data in an event stream.

*

Real Time Dashboard Sample

● We will looking at how to setup a simple dashboard to monitor per-second request count coming in to an API.
