NAME

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

VERSION

version 0.03

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 searchd query log 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;
        # 0.9.9
        my $logstr = '[Fri Oct  1 03:18:46.342 2010] 0.014 sec [ext/2/rel 55 (0,700)] [topic;topicdelta;] [ios=0 kb=0.0 ioms=0.0] @title lucky';
        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:

   {
     'performances_counters' => 'ios=0 kb=0.0 ioms=0.0',
     'total_matches' => '55',
     'match_mode' => 'ext',
     'query' => '@title lucky',
     'query_date' => 'Fri Oct  1 03:18:46.342 2010',
     'query_comment' => undef,
     'filter_count' => '2',
     'multiquery_factor' => undef,
     'index_name' => 'topic;topicdelta;',
     'limit' => '700',
     'groupby_attr' => undef,
     'query_time' => '0.014',
     'sort_mode' => 'rel',
     'offset' => '0'
   },

The log format is

    [query-date] query-time multiquery-factor [match-mode/filters-count/sort-mode total-matches (offset,limit) @groupby-attr]  [index-name] [performances-counters] [query-comment] query
    
    # optionals: multiquery-factor, @groupby-attr, performances-counters, query-comment
