Monitoring Microservices
The term “Microservice Architecture” has sprung up over the last few
years to describe a particular way of designing software applications as
suites of independent deployable services
-Martin Fowler

Monitoring Asynchronous interactions
Asynchronous programming refers to a style of structuring a program
whereby a call to some unit of functionality triggers an action that is
allowed to continue outside of the ongoing flow of the program

Monitoring failures in fault tolerant systems
• In his excellent book “Release It”, Michael Nygard talks about the Circuit
Breaker pattern as a means to prevent cascading failure.
• Hystrix, an open source framework from Netflix deals with latency and
fault tolerance for distributed systems. It includes an implementation of
Circuit Breaker pattern

• Companies like Netflix, Amazon, Google, LinkedIn, Etsy etc. deploy code
hundreds to thousands of times per day!!

Why Mobile Monitoring is so Important
• The Pew Research Center reports that 92 percent of U.S. adults have a
cellphone of some kind
• Deloitte expects digital interactions to influence 64 cents of every dollar
spent in retail stores by the end of 2015
• Users have low tolerance for buggy apps – Only 16% will try a failing app
more than twice

Monitoring Business Transactions

• Monitoring the actual user transactions is far more impactful than just
monitoring the low level application and infrastructure metrics
• Business transaction metrics provide the much needed context for the
other metrics
