AppResponse 11 Metric Descriptions
  
AppResponse 11 Metric Descriptions
AppResponse 11 metrics provide insight into the behavior of individual IP addresses or the aggregate behavior of groups. Metrics include performance and utilization data captured by AppResponse 11 directly from network traffic in real time, as well as information derived from traceroutes, BGP, DNS, and a WHOIS database in the appliance.
Use AppResponse 11’s Navigator to view aggregated groups of traffic data and metrics built by AppResponse 11 from network traffic, application stream analysis, web transaction analysis and database analysis.
AppResponse 11 captures or calculates metrics for these modules:
Application Stream Analysis (ASA) Metrics
Citrix Analysis (CXA) Metrics
Database Analysis (DBA) Metrics
Unified Communications Analysis (UCA) Metrics
Web Transaction Analysis (WTA) Metrics
Common Concepts In Metrics
Metrics are always calculated for one minute intervals. Subsequently, those one minute intervals are aggregated into longer intervals, such as five minutes and one hour. Most widgets in the AppResponse 11 user interface (charts and tables), will autoselect the granularity of interval to display based on the volume of data available.
Unless noted explicitly otherwise, metrics displayed in tables are averages of averages. Specific values, or maximum or minimum values, are displayed only when noted as such.
Application Stream Analysis (ASA) Metrics
The ASA metrics that are collected or calculated are:

Round Trip Time
This metric is an estimate of how quickly the network between the client and server would transport bits in both directions if the client and server were infinitely fast, and took no time to respond to Responses and Requests.
As of AppResponse 11 Version 11.10.0, Round Trip Time (RTT) comprises two distinct metrics: RTT (self) and RTT (others). RTT (self) is the round trip time as the traffic passes the AppResponse 11 system both from and to the originating IP address or host group. (This is similar to the RTT inbound metric that was used in AppResponse 9.) RTT (others) is the round trip time from when the traffic passes the AppResponse 11 system to when it arrives at another network element, such as an IP address or host group. (This is similar to the RTT outbound metric that was used in AppResponse 9.) RTT, undifferentiated as either (self) or (others), is the sum of the two constituent RTTs: RTT = RTT (self) + RTT (others).
See Round Trip Time for an illustration.
Server Response Time
An estimate of the average amount of time TCP servers took to send Responses to the immediately preceding client-to-server Requests they received. This is an approximate and directional measure of how much time the server takes to perform data processing before it has data to send back to the TCP clients  it is communicating with.
Server Turn Rate
The per second rate at which Server Turns were seen at the TCP servers that communicated with TCP clients in the applicable time interval.
Server Turns
The number of data direction turns that were seen at the TCP servers in the applicable time interval. A "data direction turn" is when a Request seen in one direction is immediately followed by a Response from the server in the other direction. (It is common for a Request/Response to be transferred by TCP using multiple TCP segements/packets.)
User Response Time
The overall responsiveness that the application/process experiences in its use of TCP to transfer and process the Requests and Responses that the application/process created. This metric is calculated as the sum of: (a) The amount of time it took to setup the TCP connections that map to the selected group/object (Connection Setup Time); (b) The amount of time it took to transfer all the Request bytes from client to server ignoring delays due to any retransmissions (Request Payload Transfer Time); (c) The amount of time it took to transfer all the Response bytes from server to client ignoring delays due to any retransmissions (Response Payload Transfer Time); (d) The amount of (processing) time it took the server to send responses to the requests it received from the client (Server Response Time); and (d) The amount of time taken up by retransmissions, if any (Retransmission Delay).

This is the total time of all DB sessions that were active (meaning that a query was ongoing) over the observation interval. If you have 2 DB sessions, one lasting 2 min. with 1 min. activity, and another lasting 5 min. with 2 min. activity, you will see 3 min. for this value.
Duration Logged In
This is the total time of all DB sessions that were logged in over the observation interval. If you have 2 DB sessions, one lasting 2 min., and another lasting 5 min., you will see 7 min. for this value.

DB Session ID
A session ID, usually auto-assigned by DBMS.
DB Session Idle Time
This is the total time of all DB sessions that were idle (meaning that no query was ongoing), rather than busy over the observation interval. If you have 2 DB sessions, one lasting 2 min. with 1 min. idle, and another lasting 5 min. with 2 min. idle, you will see 3 min. for this value.
DB Sessions Discarded Due To Shutdown
This is the number of sessions discarded due to an AR11 shutdown, not a DBMS shutdown. When AR11 is shutdown, the sessions that were active before the shutdown are discarded when the AR11 comes back up.

DB Session Logouts
The number of DB sessions that ended with a detected logout sequence.

DB Sessions Discarded Due To Inactivity
The number of DB sessions that did not have any query activity or a logout sequence and are presumed to have ended.
