Session Name: Know Your Data: The Stats Behind the Alerts

Quick, what's the difference between the mean, the mode and the median? Do you need a Gaussian or a normal distribution And does your choice impact the alerts and observations you get from your observability tools? Come get refreshed on the impact some basic choices in statistical behavior can have on what gets triggered. Learn why a median might be the choice for historical anomaly or sudden change. Jump into Gaussian distributions, data alignment challenges and the trouble with sampling. Walk out with a deeper understanding of your metrics and what they might be telling you.

Speaker Bio:

At NGINX, Dave works with open source projects to promote the advantages of modern architectures and orchestration to solve large-scale distributed systems challenges, especially for today's fast-moving cycles. Dave has been a champion for open systems and open source from the early days of Linux to today's world of clouds and containers. He speaks on topics such as the real-world issues associated with emerging software architectures and practices. Currently, his driving interests is app management, observability and service mesh. Dave was named as one of the top ten pioneers in open source by Computer Business Review, having cut his teeth on Linux and compilers before the phrase "open source" was coined.
