Metrics in AppResponse 11
For TCP client and server metrics, AppResponse 11 collects a single set of metrics and employs three groupings:
◼ Host Groups—Aggregations of network IP addresses representing stores, plants, sales offices, business functions, or network tiers. Host group IP addresses can be clients or servers, depending on their role in a TCP connection. Host groups can contain member host groups, allowing the definition of a hierarchies in host groups.
◼ TCP Clients—IP addresses that open a connection, that is, it sends a SYN.
◼ TCP Servers—IP addresses that respond to A TCP Client SYN.
For example, data transfer time is a single metric that appears in three groupings:
– Total Data Transfer Time [sec]
– Request Data Transfer Time [sec]
– Response Data Transfer Time [sec]
These three groupings also make it easier to interpret the data presented in Navigator tables as the direction of the traffic reported (request or response) is determined by the type of table row (Client or Server), not the type of table column metric.
AppResponse 11 metrics also allow you to monitor traffic to and from Host Groups (external) as well as traffic between Host Group members and peers (internal). TCP Clients and TCP Servers
A Host Group can include both Clients and Servers. When you see a group that reads “Group (c)” the group refers to all IP addresses in the group that sent TCP data requests within the current time interval.
Client Groups
When you see a group that reads “Group (s)” the group refers to all IP addresses in the group that received and processed TCP data requests within the current time interval.
Server Groups
When you see an IP address that reads “IP address (c)” or “IP address (s) it refers to an individual IP address acting as a client or as a server.
