Volume 9: Managing the Blue Coat SG Appliance

health check type

The kind of device or service the specific health check tests. The following types are

 

supported:

 

Forwarding host and forwarding group

 

• SOCKS gateway and SOCKS gateway group

 

CAP service and ICAP service group

 

Websense off-box service and Websense off-box service group

 

DRTR rating service

 

User-defined host and a user-defined composite

heartbeat

Messages sent once every 24 hours that contain the statistical and configuration data

 

for the SG appliance, indicating its health. Heartbeats are commonly sent to system

 

administrators and to Blue Coat. Heartbeats contain no private information, only

 

aggregate statistics useful for pre-emptively diagnosing support issues.

 

The SG appliance sends emergency heartbeats whenever it is rebooted. Emergency

 

heartbeats contain core dump and restart flags in addition to daily heartbeat

 

information.

host affinity

The attempt to direct multiple connections by a single user to the same group

 

member. Host affinity is closely tied to load balancing behavior; both should be

 

configured if load balancing is important.

host affinity timeout

The host affinity timeout determines how long a user remains idle before the

 

connection is closed. The timeout value checks the user's IP address, SSL ID, or

 

cookie in the host affinity table.

I

inbound traffic (bandwidth gain)

installable lists

integrated host timeout

Network packets flowing into the SG appliance. Inbound traffic mainly consists of the following:

Server inbound: Packets originating at the origin content server (OCS) and sent to the SG appliance to load a Web object.

Client inbound: Packets originating at the client and sent to the SG appliance for Web requests.

Installable lists, comprised of directives, can be placed onto the SG appliance in one of the following ways:

Creating the list using the SG text editor

Placing the list at an accessible URL

Downloading the directives file from the local system

An integrated host is an origin content server (OCS) that has been added to the health check list. The host, added through the integrate_new_hosts property, ages out of the integrated host table after being idle for the specified time. The default is 60 minutes.

intervals

Time period from the completion of one health check to the start of the next health

 

check.

IP reflection

Determines how the client IP address is presented to the origin server for explicitly

 

proxied requests. All proxy services contain a reflect-ip attribute, which enables or

 

disables sending of client's IP address instead of the SG's IP address.
