Chapter 22 WAN Optimization, Web Cache, Explicit Proxy, and WCCP for FortiOS 5.0 : FortiGate WCCP : Troubleshooting WCCP : Application debugging
  
Application debugging
The following commands display information about WCCP operations:
get test wccpd <integer>
diag test application wccpd <integer>
Where <integer> is a value between 1 and 5:
1. Display WCCP stats
2 Display WCCP config
3 Display WCCP cache servers
4 Display WCCP services
5 Display WCCP assignment
Enter the following command to view debugging output:
diag test application wccpd 3
Sample output from a successful WCCP connection:
service-0 in vdom-root: num=1, usable=1
cache server ID:
len=44, addr=172.16.78.8, weight=4135, status=0
rcv_id=6547, usable=1, fm=1, nq=0, dev=3(k3),
to=192.168.11.55
ch_no=0, num_router=1:
192.168.11.55
Sample output from the same command from an unsuccessful WCCP connection (because of a service group password mismatch):
service-0 in vdom-root: num=0, usable=0
diag debug application wccpd -1
Sample output:
wccp_on_recv()-98: vdom-root recv: num=160, dev=3(3),
