Citrix Systems CITRIX NETSCALER 9.3 manual Understanding the NCSA and W3C Log Formats, Example

Citrix NetScaler Administration Guide

Example

LogFileNameFormat Ex%{%m%d%y}t.log

This command creates the first file name as Exmmddyy.log, then every hour creates a file with file name: Exmmddyy.log.0, Exmmddyy.log.1,..., Exmmddyy.log.n.

Example

LogInterval size

LogFileSize 100

LogFileNameFormat Ex%{%m%d%y}t

Caution: The date format %t specified in the LogFilenameFormat command overrides the log interval property for that filter. To prevent a new file being created every day instead of when the specified log file size is reached, do not use %t in the LogFilenameFormat.

wLogExclude prevents logging of transactions with the specified file extensions.

Example

LogExclude .html

This command creates a log file that excludes log transactions for *.html files.

wLogTime specifies log time as either GMT or LOCAL. The defaults are:

•NCSA log file format: LOCAL

•W3C log file format: GMT.

Understanding the NCSA and W3C Log Formats

The NetScaler supports the following standard log file formats:

wNCSA Common Log Format

wW3C Extended Log Format

NCSA Common Log Format

If the log file format is NCSA, the log file displays log information in the following format:

Client_IP_address -User_Name [Date:Time -TimeZone] "Method Object HTTP_version" HTTP_StatusCode BytesSent

To use the NCSA Common log format, enter NCSA in the LogFormat argument in the log.conf file.

The following table describes the NCSA Common log format.
