Qpid Consumers Test

A Consumer is created when an Advanced Message Queuing Protocol (AMQP) connection wishes to receive messages from a message source (such as a Queue). When there are multiple competing consumers attached to the same message source, the Broker attempts to distribute messages from the queue in a "fair" manner. When there are multiple consumers having differing priorities, the Broker will always attempt to deliver a message to a higher priority consumer before attempting delivery to a lower priority consumer. When a consumer is created with no explicit priority provided, the consumer is given the highest possible priority. Using this test, the administrators can monitor whether/not the current state of the consumer is active ensuring that the consumers receive messages from the Queue without any distortion.

Target of the test : Apache Qpid Java Broker

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the target Apache Qpid Java Broker.

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed.

Host

The IP address of the target server that is being monitored.

Port

The port number through which the Apache Qpid Java Broker communicates. The default port is 8080.

Username

By default, the eG agent executes REST APIs on the target component to collect the required metrics. For the eG agent to execute the REST APIs, a user with monitoring privilege is required. Specify the name of such a user in this text box.

Password

Specify the password corresponding to the user mentioned in the Username text box here.

Confirm Password

Confirm the password by retyping it here.

SSL

By default, the SSL flag is set to No, indicating that the target Apache Qpid Java Broker is not SSL-enabled by default. To enable the test to connect to an SSL-enabled Apache Qpid Java Broker, set the SSL flag to Yes.

Timeout

Specify the duration (in seconds) within which the query executed by this test should time out in this text box.
