new()

The following options are possible:

data_source

Set the dsn (data source name).

You can use this parameter instead of "database", "driver", "host" and "port".

database or dbname

Pass the database name.

driver

Pass the database driver.

host

Pass the hostname where the database is running.

port

Pass the port where the database is listened.

user

Pass the database user for the connect.

password

Pass the users password.

table and columns

With this options you can pass the table name for the insert and the columns. You can pass the columns as string or as array. Example:

    # the table name
    table => "messages",

    # columns as string
    columns => "level, ctime, cdate, pid, hostname, progname, message",

    # columns as array
    columns => [ qw/level ctime cdate pid hostname progname message/ ],
    

The statement would created as follows

    insert into message (level, ctime, cdate, pid, hostname, progname, mtime, message)
                 values (?,?,?,?,?,?,?)
    

statement

With this option you can pass your own statement if you don't want to you the options "table" and "columns".

    statement => "insert into message (level, ctime, cdate, pid, hostname, progname, mtime, message)"
                 ." values (?,?,?,?,?,?,?)"
    

values

With this option you have to set the values for the insert.

        values => "%level, %time, %date, %pid, %hostname, %progname, %message",

        # or

        values => [ qw/%level %time %date %pid %hostname %progname %message/ ],
    

The placeholders are identical with the pattern names that you have to pass with the option "message_pattern" from Log::Handler.

    %L   level
    %T   time
    %D   date
    %P   pid
    %H   hostname
    %N   newline
    %C   caller
    %p   package
    %f   filename
    %l   line
    %s   subroutine
    %S   progname
    %r   runtime
    %t   mtime
    %m   message
    

Take a look to the documentation of Log::Handler for all possible patterns.

persistent

With this option you can enable or disable a persistent database connection and re-connect if the connection was lost.

This option is set to 1 on default.

dbi_params

This option is useful if you want to pass arguments to DBI. The default is set to

    {
        PrintError => 0,
        AutoCommit => 1
    }
    

"PrintError" is deactivated because this would print error messages as warnings to STDERR.

You can pass your own arguments - and overwrite it - with

    dbi_params => { PrintError => 1, AutoCommit => 0 }
    

debug

With this option it's possible to enable debugging. The information can be intercepted with $SIG{__WARN__}.

log()

    my $db = Log::Handler::Output::DBI->new(
        database   => "database",
        driver     => "mysql",
        user       => "user",
        password   => "password",
        host       => "127.0.0.1",
        port       => 3306,
        table      => "messages",
        columns    => [ qw/level ctime message/ ],
        values     => [ qw/%level %time %message/ ],
        persistent => 1,
    );

    $db->log(
        message => "your message",
        level   => "INFO",
        time    => "2008-10-10 10:12:23",
    );

Or you can connect to the database yourself. You should notice that if the database connection lost then the logger can't re-connect to the database and would return an error. Use "dbi_handle" at your own risk.

    my $dbh = DBI->connect(...);

    my $db = Log::Handler::Output::DBI->new(
        dbi_handle => $dbh,
        table      => "messages",
        columns    => [ qw/level ctime message/ ],
        values     => [ qw/%level %time %message/ ],
    );
