Real server diagnostics
Enter the following command to list all the real servers:
diag firewall vip virtual-server real-server list
In the following example there is only one virtual server called slb and it has two real-servers:
diag firewall vip virtual-server server
vd root/0 vs slb/2 addr 172.16.67.191:80 status 1/1
conn: max 10 active 0 attempts 0 success 0 drop 0 fail 0
http: available 0 total 0
vd root/0 vs slb/2 addr 172.16.67.192:80 status 1/1
conn: max 10 active 1 attempts 4 success 4 drop 0 fail 0
http: available 1 total 1
The status indicates the administrative and operational status of the real-server.
max indicates that the real-server will only allow 10 concurrent connections.
active is the number of current connections to the server attempts is the total number of connections attempted success is the total number of connections that were successful.
drop is the total number of connections that were dropped because the active count hit max.
fail is the total number of connections that failed to complete due to some internal problem (for example, lack of memory).
If the virtual server has HTTP multiplexing enabled then the HTTP section indicates how many established connections to the real-sever are available to service a HTTP request and also the total number of connections.
