Chapter 13: Data Logging 189
To check the data logging settings for connections:

2. Click Appliance Settings, click Ports and then Serial in the side navigation bar. The Serial
window will open.
3. Click on the appropriate port.
NOTE: If the Status is Disabled, you will not be able to click on the connection. To change the status to Enabled,
see Enabling and disabling data logging on units on page 188.
4. In the side navigation bar, click Data Logging.
5. If not already selected, click the radio button next to Enable DSView Data Log. Any previous
data logging settings will be lost.
6. 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.
Viewing and customizing the SSH server settings
To view and customize the SSH server settings:
1. In a Units View window, click on the appliance name.
2. Click Appliance Settings, click Data Logging and then Syslog SSH Server in the side
navigation bar.
3. In the DSView Server IP field, enter the IP address for the DSView 3 server that will receive
data logs. This may be either the hub or a spoke server.
4. In the Syslog Server Port field, enter the Syslog port that you set in Enabling the Syslog server
on page 187.
5. In the SSH Server Port field, enter the SSH port that you set in Enabling the SSH server on
page 187.
NOTE: It is recommended that no more than 2048 data logging and SSH Passthrough sessions be open
concurrently.
6. The Appliance Configuration Section contains several fields for managing the SSH sessions
and buffer warning events. Each field contains the Avocent recommended value, but you may
change these values if needed.
• SSH Idle Timeout (seconds): If the SSH session is inactive for the specified amount of
time, it will be closed. The default time-out is 15 seconds.
• SSH Start Threshold (bytes): The appliance will log data in its local memory. Once it
meets the threshold specified in this field, it will attempt to open an SSH session to the
DSView 3 server. The default threshold is 10 KB.
