Sitespeed.io is an open source tool that helps you monitor, analyze and optimize your website speed and performance, based on performance best practices advices from the coach and collecting browser metrics using the Navigation Timing API, User Timings and Visual Metrics (FirstVisualChange, SpeedIndex & LastVisualChange). Measuring performance shouldn’t be hard, you should be able to have full control of your metrics, own your own data and you should be able to do it without paying top dollars. ...

...Modular approach, each metric is generated by a separate "module". phantomas "core" acts as an events emitter that each module can hook into. In-depth metrics such as: number of events bound via jQuery, calls to window.writeor complex and duplicated CSS selectors (via analyze-css). JSON as an output format. Easy integration with other nodejs projects via CommonJS module (see API docs). Metrics can be emitted from the JavaScript code of the page phantomas is run against (thanks to helper functions available in window.__phantomas). Device profiles allow phantomas to emulate mobile or tablet (by setting a proper user agent and viewport). phantomas comes as a CommonJS module that you can use in your nodejs projects. ...

Kieker is a framework for continuous monitoring and dynamic analysis of distributed software systems. Being designed for continuous operation, it induces only a low overhead. The TraceAnalysis tool allows to analyze and visualize trace information.

...It provides developers and system administrators with tools to trace performance bottlenecks, memory usage, request distribution, regex execution, Lua execution, and file I/O behaviors in production systems. The toolkit helps identify leaks, analyze TCP queues, inspect shared memory usage, and generate flame graphs for CPU and off-CPU profiling. Many scripts are specific to NGINX worker and master processes, while others are generic enough to be applied to any Linux user-space process. Although the toolkit is no longer actively maintained—development has shifted to OpenResty XRay—it remains a valuable set of examples and utilities for advanced users of OpenResty and NGINX.

...Aims to mimic Windows procexp from sysinternals, and aims to be more usable than top and ps, especially for advanced users. Audience for this tool: * Advanced system administrators trying to analyze on process level what is going on in a production server; * Software developers analyzing the troughput of their process: e.g. TCP throughput, memory usage, memory leaks; The most advanced feature is the monitoring of TCP/IP traffic figures, for each SINGLE process (actual connections and throughput). As far as known no other tool has this capability. ...

...It takes two columns from the input file, one is used to identify the row(option -i) and the other one is the column where the values are taken from (option -v). The script was designed for performance engineers to be able to analyze CSV-Data on the fly and have a good possibility to automate the analysis process.

...Each tuning step executional time are measured in details with a comprehensive user interface and help option. The exact implementation in native code (C++) is also provided in each project folder for reference. By using these benchmarks, one may analyze: 1. How to tune/optimize the auto-parallelizer's compiler 2. Whether the appropriate optimization procedure is provided within the compiler This project is partially funded by the Department of the New Energy and Industrial Technology Development Organization (NEDO).

...It is the most comprehensive command which helps to monitor performance of various Linux / Solaris subsystems (CPU, Memory, I/O, Disk, Network, etc) all in same log. This makes it difficult to analyze since every counter data is dumped into the log file. SarBox helps to analyze this log file and present data in graphical charts or text format. To collect sar statistics from an environment, use below syntax [user@host ~]# sar -A 30 2 > sar_linux.log “30 2” reports for every 30 seconds and total of 2 times, written in sar_linux.log.

A opensource program to collect statistics and accounting information from MQ and store it into a database, which will be displayed to the end user in a visually attractive to manner to better analyze the performance of their environment.
