# Logging

This section describes parameters associated with ownCloud’s logging abilities.

Parameter | Format | Description
Log Type | “log_type” => “owncloud”, | By default the ownCloud logs are sent to the owncloud.log file within the default data directory. If syslogging is desired, set this parameter to syslog.
Log File | “logfile” => “”, | The log file, by default, is owncloud.log and stored in the default data directory. Use this parameter to change the name to something other than owncloud.log.
Log Level | “loglevel” => “”, | ownCloud has several levels of logging. This may be set on the Admin page of the webUI or directly in the configuration file using this parameter. Valid values are: 0=Debug, 1=Info, 2=Warning, 3=Error. The default value is Warning
Log Date Format | ‘logdateformat’ => ‘F d, Y H:i:s’, | ownCloud allows the admin to specify the format of the time and date within the log file. Valid values may be found at the following website: http://www.php.net/manual/en/function.date.php .
Log Time Zone | ‘logtimezone’ => ‘Europe/Berlin’, | By default, the time zone displayed in the ownCloud logs is UTC. To change the displayed time zone to the local time zone, use this parameter. For a list of valid values, see the following website: http://php.net/manual/en/timezones.php .
Log Query | “log_query” => false, | When set to “true”, all SQL queries performed by ownCloud will be written to the log file. Default is false. It is not recommended to run with this enabled as it will fill up the log file. Use only for debugging purposes.
Log Auth Fail IP | “log_authfailip” => false, | When set to true, the IP addresses of failed login attempts will be logged.
Log Rotate Size | ‘log_rotate_size’ => false, // 104857600, // 100 MiB | Since ownCloud log files can get large in size, this parameter may be used to rotate to a new log file once it reaches the specified size. This should be configured in bytes. Default is false, or 0, which will not rotate the file.
