This document discusses using the PageSpeed API and Munin to automatically track website performance over time with standard reporting. It describes PageSpeed Insights as a tool that analyzes web pages and provides optimization suggestions. The PageSpeed API allows querying page performance data via HTTP requests. Munin is presented as a tool for monitoring resources over time through graphs generated from plugins. Sample results from both tools are shown to demonstrate tracking page speed performance metrics through the PageSpeed API and visualizing them long-term using Munin.

2. Rationale
●
Automatically track website performance over
time with a standard reporting interface
●
Do not want to use or setup ShowSlow

3. PageSpeed Insights
●
“PageSpeed Insights is a tool that helps
developers optimize their web pages by analyzing
the pages and generating tailored suggestions to
make the pages faster”
●
Part of the PageSpeed tools family (browser
extensions, mod_pagespeed, PageSpeed service)
●
One HTTP GET request
●
Public API with 2.5k requests daily quota

4. PageSpeed API sample result

5. Munin
●
“Munin is a networked resource monitoring tool that can
help analyze resource trends and "what just happened to
kill our performance?" problems. It is designed to be very
plug and play. A default installation provides a lot of
graphs with almost no work.”
●
Lightweight and easy to set-up
●
Master/Node architecture
●
Graphs generated using RRDTool
●
Easy creation of plugins
