MTS Transactions Test

This test monitors the transactions executing on an MTS server.

Target of the test : A Microsoft Transaction Server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every Microsoft Transaction Server being monitored.

Configurable parameters for the test
Parameter	Description
Test period	How often should the test be executed.
Host	The IP address of the host for which this test is to be configured.
Port	The port at which the specified host listens.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Aborted transactions	The number of transactions that were aborted during the last measurement period.	Number	A high value indicates a bottleneck on the MTS server.
Aborted transactions rate	The rate at which the transactions on an MTS server aborted during the last measurement period.	Trans/Sec
Active transactions	The number of transactions that are currently active.	Number	A high value for this measure may indicate a large number of active transactions. Alternately, this may also indicate that due to some reasons the users are not able to complete the transactions.
Max active transactions	The high watermark of active transactions during the last measurement period.	Number
Committed transactions	The number of transactions that were committed during the last measurement period.	Number	This measure indicates the throughput. A higher value indicates that more transactions are being committed.
Committed transactions rate	The rate at which transactions were committed during the last measurement period.	Trans/Sec
Force aborted transactions	The number of transactions that were forcefully aborted during the last measurement period.	Number
Force committed transactions	The number of transactions that were forcefully committed during the last measurement period.	Number
In-doubt transactions	The number of transactions in doubt.	Number
Avg response time	The average time taken by the MTS server to respond to user requests.	Secs	A high response time denotes a problem. Poor response times may be due to the server being overloaded or misconfigured.
Max response time	The high water mark of response times based on replies returned by the server	Secs	If this value is consistently different from the average response time, further investigation of other server metrics may be necessary.
Min response time	The low water mark of response times based on replies returned by the server.	Secs
Total transaction rate	The number of transactions performed per second.	Trans/Sec	A high value of this metric indicates a lot of transactional activity happening on the server.
