/etc/default/nfslogd File

This file defines some of the parameters that are used when using NFS server logging. The following parameters can be defined.

CYCLE_FREQUENCY

Determines the number of hours that must pass before the log files are cycled. The default value is 24 hours. This option is used to prevent the log files from growing too large.

IDLE_TIME

Sets the number of seconds nfslogd should sleep before checking for more information in the buffer file. This parameter also determines how often the configuration file is checked. This parameter, along with MIN_PROCESSING_SIZE, determines how often the buffer file is processed. The default value is 300 seconds. Increasing this number can improve performance by reducing the number of checks.

MAPPING_UPDATE_INTERVAL

Specifies the number of seconds between updates of the records in the file-handle-to-path mapping tables. The default value is 86400 seconds or one day. This parameter helps keep the file-handle-to-path mapping tables up-to-date without having to continually update the tables.

MAX_LOGS_PRESERVE

Determines the number of log files to be saved. The default value is 10.

MIN_PROCESSING_SIZE

Sets the minimum number of bytes that the buffer file must reach before processing and writing to the log file. This parameter, along with IDLE_TIME, determines how often the buffer file is processed. The default value is 524288 bytes. Increasing this number can improve performance by reducing the number of times the buffer file is processed.

PRUNE_TIMEOUT

Selects the number of hours that must pass before a file-handle-to-path mapping record times out and can be reduced. The default value is 168 hours or 7 days.

UMASK

Specifies the file mode creation mask for the log files that are created by nfslogd. The default value is 0137.
