Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.. It's 100% free, no registration required.

I'm doing some research into how I can collect and graph useful statistics from apache per vhost:

  • Bandwidth Usage
  • Number of requests
  • Errors
  • Busy workers
  • Free workers
  • Queued/Waiting requests

Bonus points for solutions including average performance for:

  • Request time
  • Requests / second
  • Requests per keep alive connection
  • All of the above overall rather than per vhost

I've been spoiled by awesome tools like Google Analytics and Copper Egg, so I'm hoping for a tool in that vein. I want graphs of historical data, and I want something that's easy to setup. Any suggestions that require I write a log parser are on the wrong track.

There are a good number of tools out there that can contribute to my checklist but it doesn't seem like there is any one that can do it all painlessly. I even welcome commercial tools.

  • Munin (generic graphing tool)
  • Cacti (generic graphing tool)
  • OpenNMS (generic graphing tool)
  • mod_logio (bandwidth data)
  • mod_status (worker status, active requests per vhost, average requests/s)
  • AWStats (log based statistics)
  • VMware vFabric Hyperic (probably the closest thing to what I want, it looks like you can even get an apache snmp module from them for free)

Have I missed some awesome tools?

There are a few commercial tools that could help you with this. Like @Not Now said, you could look at something that does log aggregation like Logstash or Splunk. You can also look at a purely metric based solution like Metrink.
