Presented by Anisha Swain & Riya, Associate Software Engineer, Red Hat as part of PyCloud mini conference on 30th May. This talk will be highlighting the use of Pbench tool to solve this hectic task of collecting data and explain how best we utilise resources while running applications at scale. It will be beneficial for the people, who are looking for a benchmarking and performance analysis solution for their product with better consistency.

2. AGENDA
● What is Pbench?
● Why Pbench?
● Component of pbench and how they interact
● Available scripts and tools
● Dashboard
● Installation
● A video demo
● Where we can get pbench?
● How to contribute?

3. ● A benchmark & performance analysis framework
● Components
○ a collection agent
○ a server
○ a web UI dashboard
● It is a work-in-progress project

4. ● Red Hat products are mostly on distributed systems these days
● Our team members were running the same or similar benchmarks with their own
wrappers for gathering data
● We found it difficult to compare data sets, or found incomplete data depending on
who ran what
● We worked to come up with a framework that captured the best practices across
the team
● Created an agent, server, and dashboard
● 242,000+ pbench result tar balls collected since 2015, roughly 12.2+ TB of data

5. Inconsistency in data collected, and / or incomplete data collected,
surrounding a benchmark.
Goals:
● Make it easier to collect the required configuration and tool data
● Help ensure consistency of data is collected
● Provide a central location to archive, visualize, and analyze collected data
● Reuse visualizations of data to provide a more consistent view
● Facilitate easier comparisons between runs

6. Collects data
Archive, Visualize, Index
Display and compare

8. Mostly used: “fio”, “uperf”, and “user-benchmark”
Some others:
● pbench-trafficgen
● pbench-specjbb2005
● pbench-run-benchmark

9. Benchmark scripts
● pbench-user-benchmark
● pbench-fio
● pbench-uperf
● etc
Tools
● sar
● iostat
● mpstat
● pidstat
● vmstat
● perf
● etc
