Nokia IPSO 4.0 manual Configuring Logging to Remote Log Servers, 162

Caution

When you insert a PC card into a flash-based appliance and select the card as an optional disk, any existing data on the card is erased. If you remove a PC card that contains log files and want to permanently store the data, insert the card into a PC or other computer and save the data to that system before reinserting the card into a Nokia flash-based (diskless) appliance.

Log messages are temporarily stored in system memory and are stored to remote log servers and/ or PC card flash memory according to a schedule that you can configure.

Log messages are stored in the following files:

„/tmp/tmessages (in memory)—Stores most log messages.

„/var/log/messages—Stores most log messages when PC card flash memory is installed.

Note

Messages stored in http_error_log or httpd_access_log on other platforms are stored in the messages files on flash-based systems.

„/var/log/wtmp—Stores messages about shell logins and logouts. When PC card flash memory is installed, /var/log/wtmp is automatically stored on the drive.

Configuring Logging to Remote Log Servers

If you decide to use remote systems, you must configure them to store the log files. To configure your flash-based system to send syslog messages to remote log servers, use the following procedure.

To configure a flash-based system to use a remote log server

1.Click System Logging under Configuration > System Configuration in the tree view.

2.Next to Network Logging, click On.

3.Enter the IP address of the primary remote log server.

Make sure that the flash-based system has connectivity to the remote server.

4.If you want to use a secondary remote log server, enter its IP address.

If the primary log server is unreachable for any reason, the system sends its log files to the secondary log server. Make sure that the system has connectivity to the secondary server. If the primary log server is unreachable, there is a several minute delay before log messages are sent to the secondary server. The messages are stored in a buffer during this time and are sent when connectivity is established with the secondary server.

5.Set the threshold level for saving log messages to the remote server.

Flash-based systems can hold 512 log messages in a specific memory buffer. Use this configuration option to control when the messages are saved to the remote server and the buffer is cleared. For example, assume that the threshold percentage is 50 percent. When
