# get_log_service

The `get_log_service` function obtains a LuaLogService object, from which you can obtain a LuaLog object that you can use to write messages to a log file.

IMPORTANT: To obtain a `LuaLog` object for writing to a standard log stream, call the function without any arguments or use the function get_log instead. Set the `config` argument only when you want to write to a custom log file that is not controlled by the ACI Server.

## Syntax

    get_log_service( [config] )

## Arguments

Argument | Description
--- | ---
`config` | (LuaConfig) A LuaConfig object that represents the configuration file which contains the logging settings. You can obtain a LuaConfig object using the function get_config.

## Returns

(LuaLogService). A LuaLogService object.

## Example

The following example shows how to use the `get_log_service` function to obtain a `LuaLogService` object. From this you can obtain a `LuaLog` object. The `LuaLog` object has a method, `write_line`, that writes messages to the log file.

    local logService = get_log_service()
    -- import is a standard log stream for CFS
    local log = logService:get_log("import")
    log:write_line( log_level_error() , "The log message")

The get_log function provides an easier way to accomplish the same task:

    local log = get_log("import")
    -- import is a standard log stream for CFS
    log:write_line( log_level_error() , "The log message")

The following example demonstrates how to write messages to a custom log file. 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, call the `get_log_service` function outside the `handler` function.

    local luaConfigString = [===[
    [Logging]
    LogLevel=FULL
    0=LuaLogStream

    [LuaLogStream]
    LogTypeCSVs=lua
    LogFile=lua.log
    ]===]

    local config = LuaConfig:new(luaConfigString)

    -- global log service instance for Lua log stream
    luaLogService = get_log_service(config)

    local luaLog = luaLogService:get_log("lua")
    luaLog:write_line(log_level_normal(), "running Lua script")
