Zabbix will and does what it does well, but it is limited by only being
able to POST variables for progressing through a site. You can define
multiple steps and it will graph the response times with different
colours for each step, making it relatively easy to see which step is
being slowest.
I Zabbix by preference for resource monitoring, but ended up knocking up
a custom perl script for doing more complex site tests.
