Tp Requests Test

This test monitors the requests to a Transaction Processor (TP).

Target of the test : The TP server

Agent deploying the test : An internal agent

Outputs of the test : One set of outputs for the TP server monitored.

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed

Host

The host for which the test is to be configured.

Port

Refers to the port at which the specified host listens to.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Active requests

Indicates the number of requests that are actively executing.

Number

 

Current requests to the TP

Indicates the current number of requests being handled by this TP.

Number

 

Audit log requests

Indicates the number of current requests for the audit log.

Number

 

Requests to the TP

Indicates the total number of requests processed by this TP during the last measurement period.  Does not include Create/Delete session.

Number

 

Requests waiting in the TP

Indicates the number of requests that are waiting to begin active execution.

Number

 

Requests timed out in the TP

Indicates the number of requests that timed out in the past second while waiting to become active.

Number

 

Requests to the TP in the past minute

Indicates the no. of requests were executed by this TP in the last minute.

Number

 

HTML response threads in the TP

Indicates the current HTML Response Threads on the TP.

Number

 

HTML transactions in the TP

Indicates the current HTML transactions on the TP.

Number

A steady number of HTML Transactions on each TP usually is a good sign. If there is a steady decrease, it usually means that the occurrence of a few timeouts or fewer sessions to the TP. An increase in HTML Transactions on another TP may mean that a TP has died and the other TPs are inheriting the increased load.

Queued transactions for the Host Server

Indicates the number of requests in the HostServer queue waiting to be processed.

Number

 

Avg request wait time in TP

Indicates the average time for which requests that began active execution in the past second had to wait.

Secs

 

Avg response time for the HostServer process

Indicates the average time it took all HostServers under this TP to process their requests in the past minute. Does not include time spent waiting in the HostServer queue.

Secs

If this value increases, it points towards a degraded response time between the TP and the host, or a slowdown in the host itself.

Avg response time for TP processing

Indicates the average TP response time per request for the past minute.

Secs

This value includes both queueing time and execution time.

Request execution time

Indicates the average time it took to execute requests which completed in the past minute.  This time includes time spent to lookup the session key in the session map.  It does not include time spent waiting on the Regulator.
