Informix Client I/O Test

This test auto-discovers the users on the target Informix database server and periodically reports the read-write activity of each user. Using this test, administrators can easily identify which user is performing resource intensive I/O operations. This way, this test reveals the irregularities in the I/O operations performed by the users and further analyze the real reason behind the abnormally high I/O operations performed by the user.

Target of the test : An Informix Dynamic server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the each user to the Informix server being monitored.

Configurable parameters for the test
Parameters Description

Test Period

This indicates how often should the test be executed.

Host

The IP address of the Informix Dynamic server.

Port

The port number at which the specified host listens to.

Instance

The Informix server instance being monitored.

User

A valid Informix user name.

Password

The password corresponding to the above user.

Confirm Password

Confirm the Password by retyping it here.

DBLocale

Specify the language/locale in which your database is installed. This will allow you to return the query in the language supported by your database. By default this attribute is set to “none”, which means that by default, queries are returned in the English locale.

ClientLocale

Specify the language/locale in which the eG agent is running. Normally, when you use an internal agent to monitor Informix, the ClientLocale and DBLocale will be same. However, the ClientLocale may differ when you are monitoring the Informix tests using a remote agent (agentless monitoring). By default, the ClientLocale is set to “none”, indicating that the eG agent runs in the English locale, by default.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability.
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Data reads

Indicates the rate at which data was read on the database by this user during the last measurement period.

MB/second

 

Data writes

Indicates the rate at which data was written on the database by this user during the last measurement period.

MB/second

 

Read rate

  • Amount of data (in MB) read by the user
  • Number of write operations performed
  • Amount of data (in MB) written on the database server

Write rate

Indicates the rate at which the write operations were performed on the database by this user during the last measurement period.

Writes/second
