About PerfAcademyo Established in 2015 o Took almost an year of planning and interviews to design a comprehensive course o A mentor driven online learning platformo Completely focused on Performance Testing and Engineering disciplineo Live classes and cloud hosted labso Training from grass-roots levelo Open-ended problems a daily part of the courseo We strive to make our learners career readyo No 5 day courses

Real time monitoring of results in Jmetero Backend listener introduced in 2.13

o Provides graphite backend listener

o Default metrics are not enough

o Test plans with complex scenarios sufferedoMultiple Transactionso Throughput Suffered

o Cloud based executions warrant more detailed statistics

o A modified JAR File from TAG - http://www.testautomationguru.com/download/640/oMuch more detailedo No Listener neededo Light weight

Still a Problemo App / Web / DB Server health?o PerfMon listenero NO

o More listeners – More Degradation on Jmeter engineo Why? Asynchronous Threads Snowball effect

o Jmeter Master and Slaves health?

o JVM Performance of Jmeter instances?

o Can we have Jmeter do what it needs to do and do only that?o AND still have more statistical information without shelling 1000s of $

o Can we pinpoint a potential bottleneck quickly and effectively?

o What about trending of results? In a CI-CD environment, trending is of utmost importance to spot a regression

Things to watch out foro Scaling Influx once you have a considerable number of agents writing metrics is an exercise in itselfo Telegraf agents need to be restarted when you are invoking a new java process – A possible bugo Tag your transactions from Jmeter by passing along a user defined property which will make you create more informative dashboards o New in Grafana – Alerting & Thresholds mechanism. Still in beta
