Monitoring cluster status
Viewing cluster status using the bfstat utility
Bfstat is a command-line utility that resides on the security gateway. You can use the bfstat command
to monitor the current status of cluster members.
You can run bfstat from the command-line on the security gateway computer or remotely through a
standard secure shell (SSH) session. You can also use bfstat on a standalone (non-cluster) security
gateway.
The bfstat get command displays the following information:
■
The number of members in the cluster and how many members are active
■
For each active cluster member:
■
VIPs owned by the cluster member
■
Receive rate in kilobytes per second
■
Transmit rate in kilobytes per second
■
Whether the cluster member is up or down
Note: To learn about other bfstat usage, you can use the following command:

However, other bfstat commands are troubleshooting commands that you should only use if instructed
by Symantec Technical Support.
