    server-status.

        use Parse::Apache::ServerStatus;

        my $prs = new Parse::Apache::ServerStatus;

        $prs->request(
           url     => 'http://localhost/server-status',
           timeout => 30
        ) or die $prs->errstr;

DESCRIPTION
    This module parses the content of apache's server-status and countes the
    current status by each process. It works nicely with apache versions 1.3
    and 2.x.

METHODS
  new()
    Call "new()" to create a new Parse::Apache::ServerStatus object.

  request()
    This method excepts one or two arguments: "url" and "timeout". It
    requests the url and safes the content into the object. The option
    "timeout" is set to 180 seconds if it is not set.

  parse()
    Call "parse()" to parse the server status. This method returns a hash
    reference with the parsed content. There are diffenrent keys that
    contains the following counts:

       r    Requests currenty being processed
       i    Idle workers
       p    Parents
       _    Waiting for Connection
       S    Starting up
       R    Reading Request
       W    Sending Reply
       K    Keepalive (read)
       D    DNS Lookup
       C    Closing connection
       L    Logging
       G    Gracefully finishing
       I    Idle cleanup of worker
       .    Open slot with no current process

    It's possible to call "parse()" with the content as argument.

        my $stat = $prs->parse($content);

    If no argument is passed then "parse()" looks into the object for the
    content that is stored by "request()".

  get()
    Call "get()" to "request()" and "parse()" in one step. It except the
    same options like "request()" and returns the hash reference that is
    returned by "parse()".

  content()
    Call "content()" if you need the full content of server-status.

        my $content = $prs->content;

  errstr()
    "errstr()" contains the error string if the requests fails.

OPTIONS
    There are only two options: "url" and "timeout".

    Set "url" with the complete url like "http://localhost/server-status".
    There is only http supported, not https or other protocols.

    Set "timeout" to define the time in seconds to abort the request if
    there is no response. The default is set to 180 secondes if the options
    isn't set.

EXAMPLE CONFIGURATION FOR APACHE

    localhost.
