Monitoring Device Considerations

When monitoring Steelhead-optimized traffic, keep in mind:

The CA Standard Monitor monitors the following Steelhead configurations:
- Physical In-Path
- Virtual In-Path with WCCP (either GRE or Layer-2 redirection) configuration
The CA Standard Monitor automatically supports the following Steelhead WAN visibility modes:
- Correct addressing, uses Steelhead appliance addresses and ports over the WAN.
- Full Transparency, preserves the client and server IP addresses and port numbers in the packet header fields.
To report the WAN segment, a CA Standard Monitor in the data center is required to monitor Steelhead-optimized traffic on the WAN network segment. When configured with two NICs, up to two Steelhead appliances can be monitored with a single CA Standard Monitor.
To report the Server segment, a monitoring device must monitor the unoptimized server traffic in the data center. If necessary, use the CA Standard Monitor in the data center to monitor the unoptimized server traffic. A separate Monitor NIC is required to monitor Steelhead-optimized WAN traffic and the unoptimized Server segment traffic.
To report the Client segment, a CA Standard Monitor in the branch location is required to monitor traffic between the branch client computers and the branch Steelhead.
CA Application Delivery Analysis does not monitor Web applications by URL but can monitor all HTTP traffic, for example, on Port 80.
