Syntax
fw [-d] logswitch
[-audit] [<Name of Switched Log>]
-h <Target> [[+ | -]<Name of Switched Log>]
|
Parameters
Parameter
|
Description
|
-d
|
Runs the command in debug mode.
Use only if you troubleshoot the command itself.
|
-audit
|
Specifies to switch the active Audit log file ($FWDIR/log/fw.adtlog).
You can use this parameter only on a Management Server.
|
-h <Target>
|
Specifies the remote computer, on which to switch the log.
Notes:
- The local and the remote computers must have established SIC trust.
- The remote computer can be a Security Gateway, a Log Server, or a Security Management Server in High Availability deployment.
- You can specify the remote managed computer by its main IP address or Object Name as configured in SmartConsole.
|
<Name of Switched Log>
|
Specifies the name of the switched log file.
Notes:
- If you do not specify this parameter, then a default name is:
<YYYY-MM-DD_HHMMSS>.log
<YYYY-MM-DD_HHMMSS>.adtlog
For example, 2018-03-26_174455.log
- If you specify the name of the switched log file, then the name of the switch log file is:
<Specified_Log_Name>.log
<Specified_Log_Name>.adtlog
- The log switch operation fails if the specified name for the switched log matches the name of an existing log file.
- The maximal length of the specified name of the switched log file is 230 characters.
|
+
|
Specifies to copy the active log from the remote computer to the local computer.
Notes:
- If you specify the name of the switched log file, you must write it immediately after this + (plus) parameter.
- The command copies the active log from the remote computer and saves it in the
$FWDIR/log/ directory on the local computer. - The default name of the saved log file is:
<Gateway_Object_Name>__<YYYY-MM-DD_HHMMSS>.log
For example, MyGW__2018-03-26_174455.log
- If you specify the name of the switched log file, then the name of the saved log file is:
<Gateway_Object_Name>__<Specified_Log_Name>.log
- When this command copies the log file from the remote computer, it compresses the file.
|
-
|
Specifies to transfer the active log from the remote computer to the local computer.
Notes:
- The command saves the copied active log file in the
$FWDIR/log/ directory on the local computer and then deletes the switched log file on the remote computer. - If you specify the name of the switched log file, you must write it immediately after this - (minus) parameter.
- The default name of the saved log file is:
<Gateway_Object_Name>__<YYYY-MM-DD_HHMMSS>.log
For example, MyGW__2018-03-26_174455.log
- If you specify the name of the switched log file, then the name of the saved log file is:
<Gateway_Object_Name>__<Specified_Log_Name>.log
- When this command transfers the log file from the remote computer, it compresses the file.
- As an alternative, you can use the
fw fetchlogs command.

Compression
When this command transfers the log files from the remote computer, it compresses the file with the gzip command (see RFC 1950 to RFC 1952 for details). The algorithm is a variation of LZ77 method. The compression ratio varies with the content of the log file and is difficult to predict. Binary data are not compressed. Text data, such as user names and URLs, are compressed.
Example 1 - Switching the active Security log on a Security Management Server
[Expert@MGMT:0]# fw logswitch
Log file has been switched to: 2018-06-13_182359.log
[Expert@MGMT:0]#
|
Example 2 - Switching the active Audit log on a Security Management Server
[Expert@MGMT:0]# fw logswitch -audit
Log file has been switched to: 2018-06-13_185711.adtlog
[Expert@MGMT:0]#
|
Example 3 - Switching the active Security log on a managed Security Gateway
[Expert@MGMT:0]# fw logswitch -h MyGW
Log file has been switched to: 2018-06-13_185451.log
[Expert@MGMT:0]#
[Expert@MGMT:0]# ls $FWDIR/log/*.log
/opt/CPsuite-R80.30/fw1/log/fw.log
/opt/CPsuite-R80.30/fw1/log/MyGW__2018-06-13_185451.log

Example 4 - Switching the active Security log on a managed Security Gateway and copying the switched log
[Expert@MGMT:0]# fw logswitch -h MyGW +
Log file has been switched to: 2018-06-13_185451.log
[Expert@MGMT:0]#
[Expert@MGMT:0]# ls $FWDIR/log/*.log
/opt/CPsuite-R80.30/fw1/log/fw.log
/opt/CPsuite-R80.30/fw1/log/MyGW__2018-06-13_185451.log
[Expert@MGMT:0]#
[Expert@MyGW:0]# ls $FWDIR/log/*.log
/opt/CPsuite-R80.30/fw1/log/fw.log
/opt/CPsuite-R80.30/fw1/log/2018-06-13_185451.log
