 +==== Log Engine CLI Parameter ====
 +
 +The **--log-engine** parameter allows to specify what logging engine to be used, which is practically about the format of the log messages. If not set at all, then Kamailio does the classic style of line-based plain text log messages.
 +
 +The value of this parameter can be **--log-engine=name** or **--log-engine=name:data**.
 +
 +The name of the log engine can be:
 +
 +  * **json** - write logs in structured JSON format
 +    * the **data** for **json** log engine can be a set of character flags:
 +      * **a** - add log prefix as a special field
 +      * **A** - do not add log prefix
 +      * **c** - add Call-ID (when available) as a dedicated JSON attribute
 +      * **M** - strip EOL ('\n') from the value of the log message field
 +      * **N** - do not add EOL at the end of JSON document
 +
 +Example of JSON logs when running Kamailio with "**--log-engine=json:M**" :
 +
 +<code>
