Chapter 4: Diagnostics
Blue Coat Systems has a number of resources to provide diagnostic information:
Heartbeats: Enabled by default, Heartbeats (statistics) are a diagnostic tool used by 
Blue Coat, allowing them to proactively monitor the health of appliances.
Core images: Created when there is an unexpected system restarted. This stores the 
system state at the time of the restart, enhancing the ability for Blue Coat to 
determine the root cause of the restart.
SysInfo (System Information): SysInfo provides a snapshot of statistics and events 
on the SG appliance.
PCAP: An onboard packet capture utility that captures packets of Ethernet frames 
going in or out of an SG appliance.
Policy trace: A policy trace can provide debugging information on policy 
transactions. This is helpful, even when policy is not the issue. For information on 
using policy tracing, refer to Volume 10: Content Policy Language Guide.
Event Logging: The event log files contain messages generated by software or 
hardware events encountered by the appliance. For information on configuring 
event logging, see 
Access Logging: Access logs allow for analysis of Quality of Service, content 
retrieved, and other troubleshooting. For information on Access Logging, refer to 
Volume 8: Access Logging.
CPU Monitoring: With CPU monitoring enabled, you can determine what types of 
functions are taking up the majority of the CPU. 
To test connectivity, use the following commands from the enable prompt:
ping
: Verifies that a particular IP address exists and is responding to requests.
traceroute
: Traces the route from the current host to the specified destination 
host.
test http get
 
path_to_URL
: Makes a request through the same code paths as a 
proxied client.
display
 
path_to_URL
: Makes a direct request (bypassing the cache).
show services:
 Verifies the port of the Management Console configuration.
show policy
: Verifies if policy is controlling the Management Console.
For information on using these commands, refer to Chapter 2: “Standard and 
Privileged Mode Commands” in the Blue Coat ProxySG Command Line Reference.
Note:
If you cannot access the Management Console at all, be sure that you are using 
HTTPS (https://SG_IP_address:8082). If you want to use HTTP, you must 
explicitly enable it before you can access the Management Console.
