Apache: the Status module

The Status module allows a server administrator to find out how well their server is performing. A HTML page is presented that gives the current server statistics in an easily readable form. If required this page can be made to automatically refresh (given a compatible browser). Another page gives a simple machine-readable list of the current server state.

The details given are:

  • The number of worker serving requests
  • The number of idle worker
  • The status of each worker, the number of requests that worker has performed and the total number of bytes served by the worker (*)
  • A total number of accesses and byte count served (*)
  • The time the server was started/restarted and the time it has been running for
  • Averages giving the number of requests per second, the number of bytes served per second and the average number of bytes per request (*)
  • The current percentage CPU used by each worker and in total by all workers combined (*)
  • The current hosts and requests being processed (*)
