Logging, monitoring and updates 123 Managing logging To verify SNMP communication ◆ Contact the SNMP server administrator and have them send a GET from the SNMP server to your appliance. The appliance responds by sending status information to the SNMP server. If it does not respond, check that the SNMP server IP address and community string are correct. Also check that the SNMP server is accessible from the appliance. Selecting logging levels The log file contains only the types of information you choose. This is useful for isolating a problem or attack. If you select Debug information, performance may be affected by the number of messages that are created. You should select this option only for troubleshooting purposes, and then disable it when you are done. To select log levels See "Logging/Monitoring field descriptions" on page 151. 1 In the SGMI, in the left pane, click Logging/Monitoring. 2 In the right pane, on the Log Settings tab, under Log Type, check the types of information you want to be logged. 3 Click Save. Setting log times Network Time Protocol (NTP) is an Internet standard protocol that ensures accurate synchronization to the millisecond of computer clock times in a network. If you do not configure an NTP server, standard public NTP servers are used. If an NTP server is not reachable, when an event occurs, the appliance records the time (in seconds) since the last reboot. To set log times See "Log Settings tab field descriptions" on page 155. 1 In the left pane, click Logging/Monitoring. 2 In the right pane, on the Log Settings tab, under Time, in the NTP Server text box, type the IP address or fully qualified domain name of the nonpublic NTP Server. 3 Click Save.
