=============
Server Status
=============
------------------
Module: mod_status
------------------
.. meta::
:keywords: lighttpd, server status
.. contents:: Table of Contents
Description
===========
The server status module generates the status overview of the webserver. The
information covers:
- uptime
- average throughput
- current throughput
- active connections and their state
We need to load the module first. ::
server.modules = ( ..., "mod_ssi", ... )
By default the status page is disabled to hide internal information from
unauthorized users. ::
status.status-url = "/server-status"
If you want to open the status page just for users from the local network
cover it in a conditional. ::
$HTTP["remoteip"] == "10.0.0.0/8" {
status.status-url = "/server-status"
}
Or require authorization: ::
auth.require = ( "/server-status" =>
( "realm" ... ) )
Please note that when using the server.max-worker directive, the stati of the
childs are not combined yet, so you're going to see different stats with each
request.
Output Format
-------------
By default a nice looking HTML page is generated. If you append ?auto to the
status-url you can get a text version which is simpler to parse. ::
Total Accesses: 1234
Total kBytes: 1043
Uptime: 1234
BusyServers: 123
Total Accesses is the number of handled requests, kBytes the overall outgoing
traffic, Uptime the uptime in seconds and BusyServers the number of currently
active connections.
The naming is kept compatible to Apache even if we have another concept and
don't start new servers for each connection.
Server Statistics
-----------------
The server statistics is a set of counters used to track the different stati in several modules.
For example [wiki:Docs:ModFastCGI mod_fastcgi] is using it to track the usage of the backends: ::
fastcgi.active-requests: 0
fastcgi.backend.fcgi-php.0.connected: 10127
fastcgi.backend.fcgi-php.0.died: 0
fastcgi.backend.fcgi-php.0.disabled: 0
fastcgi.backend.fcgi-php.0.load: 0
fastcgi.backend.fcgi-php.0.overloaded: 0
fastcgi.backend.fcgi-php.1.connected: 93855
fastcgi.backend.fcgi-php.1.died: 0
fastcgi.backend.fcgi-php.1.disabled: 0
fastcgi.backend.fcgi-php.1.load: 0
fastcgi.backend.fcgi-php.1.overloaded: 0
fastcgi.backend.fcgi-php.load: 1
fastcgi.requests: 399355
fastcgi.requests
is a counter of the requests since the start of the server.
fastcgi.active-requests
counter of the currently active requests in the module
fastcgi.backend.*.*.load
the active requests by backend. If the load is above the number
of backend processes/threads for this backend the requests will
have to wait until a this backend is working again.
Options
=======
status.status-url
relative URL which is used to retrieve the status-page
Default: unset
Example: status.status-url = "/server-status"
status.enable-sort
add JavaScript which allows client-side sorting for the connection overview
Default: enable
status.config-url
relative URL for the config page which displays the loaded modules
Default: unset
Example: status.config-url = "/server-config"
status.statistics-url
relative URL for a plain-text page containing the internal statistics
Default: unset
Example: status.statistics-url = "/server-statistics"
