Performance monitoring?

Hi guys,

We’re looking at getting an e-commerce site created through an external provider that will be utilising Magento as the backed technology.  My manager wishes to write some performance metrics/targets into the contract. 

Can anyone recommend what we should be using to monitor the site throughout the day as well as what is classed as poor/decent/good/great?

I see sites like http://www.magespeedtest.com that show raw data as seen below but it’s certainly not “manager friendly”.  Having said that, what can be read from below?  This is a major Australian retailer that I know use Magento on the backend and hence I would expect the results to be favourable.

SIEGE 2.72
** Preparing 3 concurrent users for battle.
The server is now under siege…
Lifting the server siege...- done.

Transactions:  32 hits
Availability:  100.00 %
Elapsed time:  14.90 secs
Data transferred:  0.82 MB
Response time:  0.85 secs
Transaction rate:  2.15 trans/sec
Throughput:  0.05 MB/sec
Concurrency:  1.83
Successful transactions:  32
Failed transactions:  0
Longest transaction:  2.22
Shortest transaction:  0.70

Any information would be much appreciated.

magespeedtest.com also has a premium account that allows you to setup monitoring of load times and will alert you when they exceed your threshholds.

There are also tools like http://gtmetrix.com and http://www.webpagetest.org that will give you a more manager friendly view of how your site is performing.

As for performance metrics < 1sec TTFB (time to first byte) would be good.  < 2 wouldn’t be unreasonable depending on what your page is doing.  You’d want to specify the peak concurrent users the site can sustain.  Also make sure that your host has an SLA on support times, time to repair, etc..

PS - Testing other peoples sites with load testing tools is a faux paus.
