ZGATE API Reference UM024502-1012

ZGATE Embedded Security Development Kit

User Manual

ZGATE_set_max_logfile_size

Function Prototype

INT16 ZGATE_set_max_logfile_size( INT32 logfile_size, INT32

th_logfile_size );

Parameters

logfile_size The archiving threshold of the zgate.log file in units of 1000

bytes.

th_logfile_size The archiving threshold of the zg_thl.log file in units of 1000

bytes.

Permissible values for either parameter are:

-1 The parameter is ignored. The current archiving threshold is not

altered.

1..1000 Sets the archiving threshold between 1,000 and 1,000,000 charac-

ters.

Return Value

FALSE One or both of the input parameters is invalid.

TRUE Both parameters were accepted.

Description

When ZGATE detects an inbound packet that violates one of its filtering rules (static, SPI

or threshold), the packet is discarded and, if file logging is enabled, a new entry is added to

the corresponding log file. Static filtering and SPI filtering violations are logged to a file

named

zgate.log. Threshold filtering exceptions are logged to a file named

zg_thl.log.

All log files (and archives) are maintained in the root folder of the Zilog File System

(ZFS). If the ZTP application does not include ZFS support, ZGATE logging information

will only be displayed on the ZTP console. In this instance, the

ZGATE_set_max_logfile_size API serves no useful purpose.

This function sets the maximum size the log files are allowed to reach before being

archived. The

zgate.log file will be archived to zg_log.old, and zg_thl.log will be

archived to

zg_thl.old. The threshold point for archiving is determined by the value of

the

logfile_size and th_logfile_size parameters.
