Aspects of modern APM solutions

This document discusses the key aspects and needs of modern application performance monitoring (APM) solutions. APM solutions need to automatically adapt to complex, changing IT architectures and provide both a wide overview for operations as well as deep code-level insights for developers. They must also generate actionable alerts to help narrow down issues while avoiding false alarms that could be ignored or disturb teams.
Aspects of modern APM solutions
- 1. ASPECTS OF MODERN APM SOLUTIONS Fabian Lange, Head of Competence Center Performance codecentric AG
- 2. TODAYS CHALLENGES IN APM − Complex IT architecture − Technology mix − Large amount of IT infrastructure − Legacy does not go away − High rate of change − Multiple distributed development teams − Operations has little insight codecentric AG
- 3. TYPICAL(?) APPLICATION ARCHITECTURE Amazon EC2 Public Cloud Tomca t Jboss MQ VMware Sprin Private Cloud g Weblogi c codecentric AG
- 4. APM NEEDS TO PROVIDE − Single point for application health monitoring − APM solution has to support most existing and future technologies − Including End User Monitoring − High grade of automation − Deployment of the APM solution − Discovery of application architecture and code execution paths − Auto Configuration without expert knowledge − Change Adoption − Behavior learning − Meaningful data presentation − User view of transactions − How does the end user notice problems − Different views for various stakeholder codecentric AG
- 5. APM NEEDS TO PROVIDE − Scalable solution that can monitor − Tenths, hundreds, thousands of machines − Millions and Billions of transactions per minute − Thousands of users − Tools to narrow down root causes − Operations needs to find the needle in the haystack − Provide detail level information to responsible development team − Tools to monitor the application − Health − Load and Trends − Aggregation and Reporting codecentric AG
- 7. MTTR – MEAN TIME TO REPAIR − Is there a problem? − Baselines provide realistic thresholds − Where is the problem? − Distributed transaction tracing helps locating the root cause − Often connected to responsible dev team − What is the problem? − Drill Down allows finding details − Code Execution − Environment Metrics − User Data − Improving MTTR is the main reason for APM codecentric AG
- 9. LOAD AND PERFORMANCE TESTS − Monitoring is more important than test − Reality is different from test environment − Not reproducable problems happen in reality − Testing allows early feedback − No real customers harmed − Early tests are an integral part of agile methodologies − APM Solutions should support Production as well as Test environments codecentric AG
- 10. EASE OF USE − No time for complex tool − Time savers cannot require extra time − Not everybody is a performance expert − Collect enough data to troubleshoot problems without knowledge − Provide certain degree of automatic problem resolution − Still some problems require performance know how − Apple raised the bar for everybody codecentric AG
- 11. CHANGE − Business wants new functionality … − … and agile finally delivers − Application changes frequently … − … and with it its performance characteristics − Successful products create demand … − … which is often solved by adding resources codecentric AG
- 12. DEVOPS 1. Application Complexity cannot be handled by Operations 2. Operational Complexity is unknown to Developers − DevOps lets development and operations teams cooperate more closely − Developers learn how servers are set up and configured − Operations learn how applications are supposed to work − Developers learn the pain to be called during night − Operations learn development practices like test and version control − Major improvement for application − Development and Operations share responsibility for Applications − They need shared tooling codecentric AG
- 13. CLOUD − Cloud aka Virtualization is nothing new − APM Solutions can provide extra value − Determining the correct sizing at any time − Automatically reconfigure the application by load pattern − APMaaS − APM solutions can leverage SaaS models − Low cost of ownership − Pay Per use codecentric AG
- 15. SUMMARY − IT Applications change fast − APM Solution needs to adapt automatically − Support for multiple languages, frameworks and protocols − Operations need wide overview, but Developers need deep insight − An APM Solution has to provide both − Alerts need to be actionable − False alarms disturb − No red light should be ever ignored − APM solution should be able to alert the right thing codecentric AG
