Grab pagespeed results from external services to use them in e.g. munin.
Currently only support webpagetest.org, which is not very reliable and sometimes slow.

Not ready for production just a toy project.

data = PagespeedGrabber.fetch('google.com', :from => 'webpagetest', :timeout => 200)

Munin

1 of 8 graphs generated via munin: Pagespeed score over 1 day for initial request:
score for initial reqest over 1 day

Download

sudo su

gem install pagespeed_grabber
curl --insecure https://github.com/grosser/pagespeed_grabber/raw/master/munin.rb > /usr/share/munin/plugins/pagespeed_grabber
chmod +x /usr/share/munin/plugins/pagespeed_grabber

Add data cron and run it once

*/5 * * * * ruby /usr/share/munin/plugins/pagespeed_grabber cache webpagetest google.com

Add plugins for time, data, score, connections graphs

ruby -e "%w[time data score connections].each{|s| %w[initial repeated].each{|t| %x{ln -s /usr/share/munin/plugins/pagespeed_grabber /etc/munin/plugins/webpagetest_#{s}_#{t}_google.com}  } }"

Check plugins work

ruby /etc/munin/plugins/webpagetest_time_google.com config    # config works
ruby /etc/munin/plugins/webpagetest_time_google.com           # values are returned

Restart

/etc/init.d/munin-node.restart

TODO

  • add other services
  • make less hacky/use official apis
  • generate initial AND repeated graph
  • find a reliable service
  • parse .har file from e.g. loads.in
