Introduction
● What API Manager Offers.
● Collecting & Analysing statistic with BAM.
● Analysing & Visualizing Stats ( Example ).
● Real Time data analysis & alerting with CEP.
6. *
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+Statisti
cs
● 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
10. 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
11. *
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.
