Logging
|
|
=======
|
|
|
|
Use your Nextcloud log to review system status, or to help debug problems. You may adjust logging levels, and choose between using the Nextcloud log or your syslog.
|
|
|
|
Log level
|
|
---------
|
|
|
|
Logging levels range from **DEBUG**, which logs all activity, to **FATAL**, which logs only fatal errors.
|
|
|
|
* **0**: DEBUG: All activity; the most detailed logging.
|
|
* **1**: INFO: Activity such as user logins and file activities, plus warnings, errors, and fatal errors.
|
|
* **2**: WARN: Operations succeed, but with warnings of potential problems, plus errors and fatal errors.
|
|
* **3**: ERROR: An operation fails, but other services and operations continue, plus fatal errors.
|
|
* **4**: FATAL: The server stops.
|
|
|
|
By default the log level is set to **2** (WARN). Use **DEBUG** when you have a problem to diagnose, and then reset your log level to a less-verbose level as **DEBUG** outputs a lot of information, and can affect your server performance.
|
|
|
|
Logging level parameters are set in the :file:`config/config.php` file.
|
|
|
|
Log type
|
|
--------
|
|
|
|
file
|
|
~~~~
|
|
|
|
All log information will be written to a separate log file which can be
|
|
viewed using the log viewer on your Admin page. By default, a log
|
|
file named **nextcloud.log** will be created in the directory which has
|
|
been configured by the **datadirectory** parameter in :file:`config/config.php`.
|
|
|
|
The desired date format can optionally be defined using the **logdateformat** parameter in :file:`config/config.php`.
|
|
By default the `PHP date function`_ parameter ``c`` is used, and therefore the
|
|
date/time is written in the format ``2013-01-10T15:20:25+02:00``. By using the
|
|
date format in the example below, the date/time format will be written in the format
|
|
``January 10, 2013 15:20:25``.
|
|
|
|
::
|
|
|
|
"log_type" => "file",
|
|
"logfile" => "nextcloud.log",
|
|
"loglevel" => "3",
|
|
"logdateformat" => "F d, Y H:i:s",
|
|
|
|
syslog
|
|
~~~~~~
|
|
|
|
All log information will be sent to your default syslog daemon.
