Several sites have wanted a way to provide central logging of job status and/or information. In order to do this, the following functionality is implemented in LPRng.
21.1. Logger Network Communication
Options used:
-
logger_destination=logger information destination
-
logger_pathname=pathname of temp file for log information
-
logger_max_size=max size in K of temp file for log information
-
logger_timeout=time between connection attempts
The printcap/configuration variable logger_destination specifies a destination in the standard host%port notation used by LPRng. Host is the destination host, and can be a name or IP address. Port is the port on the destination host. A TCP/IP connection is made to the indicated port.
Log information is save in a temporary file specified by logger_path, and up to logger_max_size K bytes of data will be saved.
If a connection cannot be made to the logger_destination, then every logger_timeout seconds a new connection attempt will be made. If logger_timeout is 0, then a connection attempt will be made every time new data arrives to be logged.
