Brendan Gregg is a kernel and performance engineer at Netflix, known for his work in systems performance analysis. He previously worked at Sun Microsystems, Oracle Corporation, and Joyent.
Gregg was born in Newcastle, New South Wales and attended University of Newcastle, Australia. After working as a technical instructor for Sun Microsystems and later as a consultant, he was hired to join Sun's Fishworks team in San Francisco. In October, 2010, he left Oracle for a position as a Lead Performance Engineer at Joyent. In March, 2014, he became a Senior Performance Architect at Netflix.
Gregg is one of the leading experts on DTrace, creator of the DTraceToolkit,[1] and author of books on DTrace and systems performance. He is also the star of the Shouting in the Data Center viral video.[2]
In November, 2013, he was awarded the LISA Outstanding Achievement Award 'For contributions to the field of system administration, particularly groundbreaking work in systems performance analysis methodologies.'[3]
He now investigates and writes about Linux performance on his new blog.[4]
Contributions[edit]
Gregg has developed various methodologies for performance analysis, notably the USE Method methodology (short for Utilization Saturation and Errors Method).[5]
He has also created visualization types to aid performance analysis, including latency heat maps,[6] utilization heat maps, subsecond offset heat maps, and flame graphs.[7]

Overview
The Complete Guide to Optimizing Systems Performance
Written by the winner of the 2013 LISA Award for Outstanding Achievement in System Administration
Large-scale enterprise, cloud, and virtualized computing systems have introduced serious performance challenges. Now, internationally renowned performance expert Brendan Gregg has brought together proven methodologies, tools, and metrics for analyzing and tuning even the most complex environments. Systems Performance: Enterprise and the Cloud focuses on Linux® and Unix® performance, while illuminating performance issues that are relevant to all operating systems. Youâll gain deep insight into how systems work and perform, and learn methodologies for analyzing and improving system and application performance. Gregg presents examples from bare-metal systems and virtualized cloud tenants running Linux-based Ubuntu®, Fedora®, CentOS, and the illumos-based Joyent® SmartOS⢠and OmniTI OmniOS®. He systematically covers modern systems performance, including the âtraditionalâ analysis of CPUs, memory, disks, and networks, and new areas including cloud computing and dynamic tracing. This book also helps you identify and fix the âunknown unknownsâ of complex performance: bottlenecks that emerge from elements and interactions you were not aware of. The text concludes with a detailed case study, showing how a real cloud customer issue was analyzed from start to finish.
