                       java.lang.String expirationTime)

Convenience routine to initialized the RollingLogFile specific attributes.

startup

public void startup()
             throws EBaseException

Description copied from class: LogFile

Startup the instance

• signed.audit LOGGING_SIGNED_AUDIT_AUDIT_LOG_STARTUP used at audit function startup

Specified by:

startup in interface ILogEventListener

Overrides:

startup in class LogFile

Throws:

EBaseException - if an internal error occurred

shutdown

public void shutdown()

Shutdown this log file.

Specified by:

shutdown in interface ILogEventListener

Overrides:

shutdown in class LogFile

setRolloverTime

public void setRolloverTime(java.lang.String rolloverSeconds)

Set the rollover interval

Parameters:

rolloverSeconds - The amount of time in seconds until the log is rotated. A value of 0 will disable log rollover.

getRolloverTime

public int getRolloverTime()

Get the rollover interval

Returns:

The interval in seconds in which the log is rotated

setExpirationTime

public void setExpirationTime(java.lang.String expirationSeconds)

Set the file expiration time

Parameters:

expirationSeconds - The amount of time in seconds until log files are deleted

getExpirationTime

public int getExpirationTime()

Get the expiration time

Returns:

The age in seconds in which log files are delete

rotate

public void rotate()
            throws java.io.IOException

Rotate the log file to a backup file with timestamp

Throws:

expire

public long expire(long expirationSeconds)
            throws ELogException

Remove any log files which have not been modified in the specified time

NOTE: automatic removal of log files is currently NOT supported!

• signed.audit LOGGING_SIGNED_AUDIT_LOG_DELETE used AFTER audit log expires (authorization should not allow, but in case authorization gets compromised make sure it is written AFTER the log expiration happens)

Parameters:

expirationSeconds - The number of seconds since the expired files have been modified.

Returns:

the time in milliseconds when the next file expires

Throws:

ELogException

getExtendedPluginInfo

public java.lang.String[] getExtendedPluginInfo(java.util.Locale locale)

Description copied from interface: IExtendedPluginInfo

This method returns an array of strings. Each element of the array represents a configurable parameter, or some other meta-info (such as help-token) there is an entry indexed on that parameter name ;[,required];;... Where: type_info is either 'string', 'number', 'boolean', 'password' or 'choice(ch1,ch2,ch3,...)' If the marker 'required' is included after the type_info, the parameter will has some visually distinctive marking in the UI. 'description' is a short sentence describing the parameter 'choice' is rendered as a drop-down list. The first parameter in the list will be activated by default 'boolean' is rendered as a checkbox. The resulting parameter will be either 'true' or 'false' 'string' allows any characters 'number' allows only numbers 'password' is rendered as a password field (the characters are replaced with *'s when being types. This parameter is not passed through to the plugin. It is instead inserted directly into the password cache keyed on the instance name. The value of the parameter 'bindPWPrompt' (see example below) is set to the key. In addition to the configurable parameters, the following magic parameters may be defined: HELP_TOKEN;helptoken - a pointer to the online manual section for this plugin HELP_TEXT;helptext - a general help string describing the plugin For example: "username;string;The username you wish to login as" "bindPWPrompt;password;Enter password to bind as above user with" "algorithm;choice(RSA,DSA);Which algorithm do you want to use" "enable;boolean;Do you want to run this plugin" "port;number;Which port number do you want to use"

Specified by:

getExtendedPluginInfo in interface IExtendedPluginInfo

Overrides:

getExtendedPluginInfo in class LogFile
