Jboss Connection Pools Test

This test monitors the various connection pools configured in the JBoss server, and reveals how well the pools have been used.

Target of the test : A JBoss application server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every JBoss 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

The port number at which the specified host listens to.

Measurement Mode

This test can extract metrics from JBoss using either of the following mechanisms:

  • By deploying the EgJBossAgent.sar and egjboss.war files on the target JBoss server;
  • By contacting the Java runtime (JRE) of JBoss viaJMX

To configure the test to usethe EgJBossAgent.sar and egjboss.war files, first, select the War File option. Then, refer to the How to Monitor JBoss Application Server Using eG Enterprise? chapter to know how to deploy these files on the target JBoss server.

On the other hand, if you want the test to use JMX instead, then first, select the jmx option. Then, follow the procedure detailed in the How to Monitor JBoss Application Server Using eG Enterprise? chapter to configure the test to use jmx. By default, the jmx option is chosen here.

JNDIName

This parameter appears only if the Measurement Mode is set to jmx. The JNDIName is a lookup name for connecting to the JMX connector. By default, this is jmxrmi. If you have registered the JMX connector in the RMI registry using a different lookup name, then you can change this default value to reflect the same.

JMX Remote Port

This parameter appears only if the Measurement Mode is set to jmx. Here, specify the port at which the jmx listens for requests from remote hosts. Ensure that you specify the same port that you configured in the management.properties file of the target JBoss server (refer to the How to Monitor JBoss Application Server Using eG Enterprise? chapter for more details).

JMX User, JMX Password, and Confirm Password

These parameters appear only if the Measurement Mode is set to jmx. If JMX requires authentication only (but no security), then ensure that the JMX User and JMX Password parameters are configured with the credentials of a user with read-write access to JMX. To know how to create this user, refer to the How to Monitor JBoss Application Server Using eG Enterprise? chapter. Confirm the password by retyping it in the Confirm Password text box.

SSL

This parameter appears only if the Measurement Mode is set to War File. Indicate Yes if the JBoss server is SSL-enabled.

URL

This parameter appears only if the Measurement Mode is set to War File. Specify the URL to be accessed to collect metrics pertaining to the JBoss server. By default, this test connects to a managed JBoss server and attempts to obtain the metrics of interest by accessing the local Mbeans of the server. Accordingly, by default, this parameter is set to http://<JBossServerIP>:<JbossServerPort>.

JMX Provider

This parameter appears only if the Measurement Mode is set to jmx. This test uses a JMX Provider to access the MBean attributes of the JBoss server and collect metrics. Specify the package name of this JMX Provider here. By default, this is set to com.sun.jmx.remote.protocol.

Timeout

Specify the duration (in seconds) for which this test should wait for a response from the JBoss server. If there is no response from the server beyond the configured duration, the test will timeout. By default, this is set to 240 seconds.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Connections created

Indicates the total number of connections created since the start of the connection pool.

Number

 

Current connections

Indicates the number of connections currently in the pool.

Number

 

Connections in use

Indicates the number of connections that are currently in use.

Number

If the value of this measure reaches that of the Current connections measure, then it indicates that the pool requires resizing.

Connections destroyed

Indicates the number of connections that were destroyed since the start of the server.

Number

 

Max connections in use

Indicates the high water mark of the connections in use count.

Number

 

Available connections

Indicates the number of connections that are currently available in the pool for clients to use.

Number

Ideally, this value should be high.

Min connection size

Indicates the minimum value of the number of connections in the pool since the start of the pool.

Number

 

Max connection size

Indicates the maximum value of the number of connections in the pool since the start of the pool.

Number
