Unified Monitoring Dustin Whittle, Developer Evangelist

Uptime is critical for enterprises and consumers

Performance impacts the bottom line

How fast is fast enough? •  Performance is key to a great user experience

-  Under 100ms is perceived as reacting instantaneously

-  A 100ms to 300ms delay is perceptible -  1 second is about the limit for the user's flow of thought to stay uninterrupted

-  Users expect a site to load in 2 seconds -  After 3 seconds, 40% will abandon your site.

-  10 seconds is about the limit for keeping the user's attention •  Modern applications spend more time in the browser than on the server-

side

Who cares about performance?

How many enterprise monitoring products would you estimate your IT org owns?

The war room response team

The problems with monitoring tools •  Root cause isolation is elusive as monitoring lives in silos

-  Infrastructure -  Hardware + Logs + Network + Storage + Containers + VMs

-  Application -  Load Balancers + Web Servers + App Servers + File Servers -  Databases + Caches + Queues + Third party services

-  End Users -  CDN -  Web + Mobile

•  Metrics lack the context of impact

Monitoring lacks the business context

The struggle of modern monitoring •  Organizations focus on availability + raw metrics and not end user

experience / impact •  Complex apps built on micro-services in containers living in elastic cloud

environments •  Too many graphs from too many metrics

-  Understanding the signal from the noise is difficult -  No topology awareness. No transactional visibility. No root cause.

•  Alert storming with too many false alarms -  Alerting is based on static thresholds — lacks intelligent anomaly detection +

correlation -  Lack of historical context or relationships between metrics and events

•  A single pane of glass across the performance stakeholders -  Not able to quantify the impact of performance degradation — Not self-

service

Context is king: Unified Monitoring

Breaking down the silos

Situation-aware data and views

Monitor the end user experience •  Real User Monitoring vs Synthetic Monitoring

-  Synthetic tests provide 24/7 assurance -  RUM provides insights into actual users

-  Mobile device segmentation -  Unexpected behavior/trends

•  Real User Monitoring -  Navigation Timing API -  Resource Timing API -  User Timing API -  Javascript Errors

Metrics + logs help, but intelligence is better

Moving from reactive to proactive •  Resolving before the red = fixing in the yellow

-  Automatic runbook automation integrates with your devops stack •  Intelligent anomaly detection across end-user, application, database, server

metrics -  Automatically calculates dynamic baselines for all of your metrics, which,

based on actual usage, define what is "normal" for each metric -  Smart alerting based on any deviation from the baselines

•  Understand trends and patterns in failures - automatically learn from the past -  Understand what are the most impactful issues to resolve -  Often times external services are the root cause with limited visibility

-  Enforce SLAs

Moving from reactive to proactive -  Automatic discovery of environment and application changes

-  New APIs, transactions, services, clouds •  Leverage analytics to be smarter about using the data you already have

-  System Logs, Metrics from events and infrastructure stats -  Transactions with request parameters + User state from cookies/sessions

•  Performance monitoring isn’t just about the tech -  Visibility into the impact of business - alerting when revenue is down

AppDynamics leverages and embraces open-source

Leading companies invest in performance •  Etsy = Kale = Statsd + Skyline + Oculus (stats collection + anomaly detection/

correlation) •  Netflix = PCP + Vector + Servo + Atlas (dashboards, data collection, root cause

analysis) •  Twitter = Zipkin (distributed tracing)

Recommendations •  Treat performance as a feature

-  Create a performance budget with milestones, speed index, page speed -  Capacity plan and load test the server-side -  Optimize and performance test the client-side

•  Monitor performance in development and production -  Instrument everything -  Measure the difference of every change -  Understand how failures impact performance

•  Make monitoring critical and test in your continuous delivery process •  Connect the exec/dev/ops performance perspectives to align on business

impact

monitoring silos and be more impactful with application intelligence.
