LuaLogService:new
The constructor for a LuaLogService
object (creates a new LuaLogService
).
IMPORTANT: Do not create a new log service to write messages to log types that are defined in the Google Cloud Storage Connector configuration file. Instead use the same log service as Google Cloud Storage Connector, by calling get_log_service, or obtain a LuaLog
object through the function get_log.
Syntax
LuaLogService:new( config )
Arguments
Argument | Description |
---|---|
config
|
(LuaConfig) The configuration object to read the logging settings from. You can obtain a LuaConfig object through the function get_config. |
Returns
(LuaLogService). The new LuaLogService
object.
Example
The following example creates a LuaLogService
object to write log messages to a custom log file named lua.log
. Declare the log service globally to avoid a LuaLogService
object being created every time the script runs. For example, if you are writing a Lua script to use with a connector or CFS, create the LuaLogService
outside the handler
function. Otherwise, the server creates a LuaLogService
object for every document that is processed.
