Db I/O Stats Test

This test indicates how efficiently MaxDB handles read/write requests to the database.

Target of the test : A MaxDB server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every data volume and log volume on the MaxDB server being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The host name of the server for which the test is to be configured.

Port

The port number to which the server is listening.

DatabaseName

The test connects to a database on MaxDB and extracts performance statistics from the system tables in the database. Therefore, provide the name of a database in the DatabaseName text box.

Username

Since users with the SYSDBA privilege alone are allowed access to system tables, specify the name of such a user against Username.

Password

Provide the Password that corresponds to the specified Username.

Confirm Password

Confirm the password by retyping it here.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Database read rate

Indicates the rate at which database reads were performed.

Reads/Sec

 

Page read operations

Indicates the rate at which page reads were performed.

Pages/Sec

 

Database read time

Indicates the time taken by the database to perform read operations in the last measurement period.

Secs

A high value of this measure indicates a reading bottleneck.

Database write rate

Indicates the rate at which data is written to the database.

Writes/Sec

 

Page write operations

Indicates the rate at which page writes were performed.

Pages/Sec

 

Database write time

Indicates the time taken by the database to perform write operations in the last measurement period.

Secs

A high value of this measure indicates a writing bottleneck.

Pending I/O operations

Indicates the number of IO operations still to be completed.

Number

If the value of this measure keeps increasing, it is indicative of a processing bottleneck.
