This category provides metrics from the perspective of servers that are hosting the applications being monitored by the appliance. Some of the low level reports that are provided include number of bytes, packets, and messages sent to and from each server; the number of TCP connections started, stopped, or reset; as well as response and processing times. High-level reports include success rates, which objects are not found, and network delays between users and specific servers. The metrics in this category help network administrators identify which servers may be performing poorly or are in danger of becoming overloaded.
This category provides metrics on the SSL traffic for each port of all monitored servers. These metrics are useful in discovering possible problems the system is having with monitoring the SSL traffic for a specific server.
This category provides aggregate metrics for HTTP and HTTPS traffic the appliance is monitoring. In order for this category of metrics to provide data, protocol definitions specifying the ports used for HTTP and HTTPS must be defined in the web console.
This category provides metrics from the perspective of a TCP-based protocol. In order for this category of metrics to provide data, protocol definitions specifying the ports used for each TCP protocol you would like to monitor must be defined in the web console. Protocols are identified by a list of TCP port numbers. The system will generate metrics for any TCP-based protocol (for example, FTP, SMTP, LDAP) as long as it has been configured.
