•Buffer Full First Warning (bytes): If an SSH session cannot be opened, a first warning will be sent once the appliance local memory reaches the size specified in this field. The recommended first warning size is 500KB.

•Buffer Full Second Warning (bytes): If an SSH session cannot be opened, a second warning will be sent once the appliance local memory reaches the size specified in this field. The recommended second warning size is 700 KB.

Configuring the buffer warnings events as SNMP

If the appliance fails to open an SSH connection to the DSView 3 server, the appliance will continue to store data logs in local memory. To ensure that the administrator receives buffer warnings events if the SSH connection fails, change the notification mode from Syslog to SNMP.

To configure the buffer warnings as SNMP:

1.In a Units View window, click on the appliance name.

2.Select Appliance Settings - Events - Traps/Syslog.

3.Click the checkbox next to the following events: Appliance Data Log Buffer Full First Warning, Appliance Data Log Buffer Full Second Warning and Appliance Data Log Loss.

4.Click the Enable SNMP Trap button.

5.The Notification Mode for the events changes from Syslog Enabled to SNMP Trap Enabled.

If available, click the Flash Required button to ensure that these settings remain even if power is interrupted. If the Flash Required button is not displayed, the settings have been saved to non-volatile Flash memory on the appliance.

To begin receiving buffer warning events, configure the DSView 3 software for email notifications. See Email Notifications in the DSView 3 software online help for more information.
