NAME
    Sphinx::Log::Parser - parse Sphinx searchd log

VERSION
    version 0.01

SYNOPSIS
        use Sphinx::Log::Parser;

        my $parser = Sphinx::Log::Parser->new( '/var/log/searchd/query.log' );
        while (my $sl = $parser->next) {
            print $sl->{total_matches}, $sl->{query_date}, "\n"; # more
        }

DESCRIPTION
    Sphinx::Log::Parser parse sphinx searchd query.log based on
    <http://sphinxsearch.com/docs/current.html#query-log-format>

  Constructing a Parser
    new requires as first argument a source from where to get the syslog
    lines. It can be:

    *   a filename for the searchd query log to be parsed. check query_log
        in conf file

    *   an IO::Handle object.

    *   a File::Tail object as first argument, in which case the *read*
        method will be called to get lines to process.

    *   The log string, you need use IO::Scalar

            use IO::Scalar;
            my $logstr = '[Fri Jun 29 21:20:34 2007] 0.024 sec [all/0/rel 19886 (0,20) @channel_id] [lj] test';
            my $io = new IO::Scalar \$logstr;
            my $parser = Sphinx::Log::Parser->new( $io );

  Parsing the file
    The file is parse one line at a time by calling the next method, which
    returns a hash-reference containing the following keys:

        {
          'total_matches' => '19886',
          'match_mode' => 'all',
          'query' => 'test',
          'query_date' => 'Fri Jun 29 21:20:34 2007',
          'filter_count' => '0',
          'index_name' => 'lj',
          'limit' => '20',
          'query_time' => '0.024',
          'sort_mode' => 'rel',
          'groupby_attr' => 'channel_id',
          'offset' => '0'
        }

    The log format is

        [query-date] query-time [match-mode/filters-count/sort-mode
            total-matches (offset,limit) @groupby-attr] [index-name] query
