Defines the type of messages that should be logged, and down to
|
||
which level of importance they should be considered.
|
||
|
||
The possible types are “artwork”, “database”, “general”, “http”,
|
||
“inotify”, “metadata”, “scanner”, “ssdp” and “tivo”.
|
||
|
||
The levels are “off”, “fatal”, “error”, “warn”, “info” and
|
||
“debug”, listed here in order of decreasing importance. “off”
|
||
turns off logging messages entirely, “fatal” logs the most
|
||
critical messages only, and so on down to “debug” that logs every
|
||
single messages.
|
||
|
||
The types are comma-separated, followed by an equal sign (‘=’),
|
||
followed by a level that applies to the preceding types. This can
|
||
be repeated, separating each of these constructs with a comma.
|
||
|
||
Defaults to “general,artwork,database,inotify,scanner,metadata,
|
||
http,ssdp,tivo=warn” which logs every type of message at the
|
||
“warn” level.
