Hi folks.

We're looking at getting an ecommerce site hosted with a reputable provider, just looking for some recommendations on monitoring software (opensource or not) that will chart performance stats. Not so much just up/down, but load times of images, time between page loads / links etc.

This may not be very straight forward given the ecommerce nature in that everything will be SSL but thought I'd throw it out there. Site will be based on the magento ecommerce stuff.

Cheers

^^ agreed. what he said plus google analytics for another view ( especially if you want to track adwords campaigns etc ) and PagerDoody to wake you up at strange hours to fix it when it breaks.


although once you're [way] bigger you might want to roll your own using logstash/sensu/statsd/graphite/etc

You can either do real user monitoring or synthetic monitoring. I suspect you want synthetics.

Here's a couple of the synthetic guys I've come across for a managed solution.
