# write_line

The `write_line` method writes a message to the log stream.

## Syntax

    write_line( level, message )

## Arguments

Argument | Description
--- | ---
`level` | The log level for the message. The message only appears in the log if the log level specified here is the same as, or higher than, the log level set for the log stream. To obtain the correct value for the log level, use one of the following functions: `log_level_always()` `log_level_error()` `log_level_warning()` `log_level_normal()` `log_level_full()`
`message` | (string) The message to write to the log stream.

## Example

To write a log message from the ExecuteDocumentLua processor in NiFi:

    local log = get_log()
    log:write_line(log_level_normal(), "doing something...")

    -- or use the following functions
    log_info("My information message")
    log_warn("My warning message")
    log_error("My error message")

To write a log message to an ACI Server application log:

    local log = get_log("application")
    log:write_line(log_level_normal(), "doing something...")
