Monitoring and Managing WebLogic JMS Servers

Overview

WebLogic JMS servers can be monitored and managed using various tools and techniques. Some of the popular approaches are:

1. WebLogic Console: WebLogic provides a web-based administration console to monitor and manage JMS servers. Using the console, you can view JMS server configuration, monitor message queues and topics, and manage JMS resources.
2. JMX Monitoring: JMS servers can be monitored using JMX (Java Management Extensions) technology. WebLogic provides JMX MBeans (Managed Beans) that expose JMS server attributes and operations for monitoring and management.
3. WLST Scripting: WebLogic Scripting Tool (WLST) can be used to write scripts for monitoring and managing JMS servers. WLST provides a command-line interface to connect to a WebLogic domain and execute commands to monitor and manage JMS servers.
4. Third-Party Tools: Several third-party monitoring and management tools are available in the market that can be used to monitor and manage JMS servers. Some popular tools include Nagios, Zabbix, and PRTG.

By using these tools and techniques, administrators can monitor and manage WebLogic JMS servers to ensure their availability, reliability, and performance.

Monitoring from Weblogic Console

WebLogic Console provides an intuitive and user-friendly interface for monitoring and managing JMS Servers. Here are the steps to monitor and manage JMS Servers from WebLogic Console:

1. Open WebLogic Console and navigate to the domain that contains the JMS Servers you want to manage.
2. From the Domain Structure menu, select JMS Servers. This will display a list of all JMS Servers in the domain.
3. Select the JMS Server you want to monitor and manage from the list.
4. The Summary of JMS Server page will provide a high-level view of the JMS Server’s state, including the number of destinations, number of connections, and current message count.
5. From the left navigation pane, you can access different management options like monitoring, configuration, and control of the JMS Server.
6. To monitor the JMS Server, select Monitoring from the left navigation pane. This page will display real-time performance metrics like message count, connection count, and message consumption rate.
7. To configure the JMS Server, select Configuration from the left navigation pane. This page will allow you to modify settings like destination quotas, message logging, and server migration.
8. To control the JMS Server, select Control from the left navigation pane. This page will allow you to start, stop, and restart the JMS Server.
9. After making any changes, remember to save the changes and activate them.

Overall, WebLogic Console provides a comprehensive set of tools for monitoring and managing JMS Servers. By regularly monitoring and fine-tuning JMS Server settings, you can ensure reliable message delivery and optimize JMS Server performance.

JMX Monitoring

JMX (Java Management Extensions) monitoring provides a way to monitor and manage the JMS (Java Message Service) servers in WebLogic. JMX is a Java-based technology that enables you to manage and monitor Java applications, devices, and services.

To monitor and manage JMS servers using JMX, you can use tools such as JConsole or JVisualVM. These tools allow you to connect to the JMS server and view various statistics and metrics related to JMS, such as the number of messages in a queue or the number of consumers connected to a topic.

Once you have connected to the JMS server using JMX, you can view various MBeans (Managed Beans) related to JMS. These MBeans provide information about the JMS server, destinations (queues and topics), connections, sessions, and subscribers. You can also perform various operations on these MBeans, such as creating or deleting destinations, changing the configuration of the JMS server, or monitoring the activity of consumers.

JMX monitoring provides a powerful way to manage and monitor JMS servers in WebLogic. It allows you to monitor the health and performance of JMS servers and quickly diagnose and fix any issues that may arise.

Monitoring through WLST scripting

You can monitor and manage JMS servers using WLST scripting in WebLogic. WLST provides various built-in functions and commands to manage JMS servers, including starting and stopping JMS servers, creating or deleting JMS resources, monitoring JMS queues and topics, and configuring JMS server parameters.

Here are some examples of WLST scripting commands for monitoring and managing JMS servers:

Start or Stop a JMS Server (below code is in python)

start(name='myJMSServer', type='JMSServer')
stop(name='myJMSServer', type='JMSServer')

Create a JMS resource:

edit()
startEdit()
jmsModule = create("myJMSModule", "JMSSystemResource")
jmsResource = jmsModule.getJMSResource()
queue = jmsResource.createQueue("myQueue")
topic = jmsResource.createTopic("myTopic")
save()
activate()

Delete a JMS resource:

edit()
startEdit()
jmsModule = delete("myJMSModule", "JMSSystemResource")
save()
activate()

Monitor JMS queues and topics:

connect(username, password, url)
jmsServerRuntime = getRuntimeJMSServer('myJMSServer')
queues = jmsServerRuntime.getJMSQueues()
topics = jmsServerRuntime.getJMSTopics()
for queue in queues:
    print queue.getName(), queue.getMessagesCurrentCount()
for topic in topics:
    print topic.getName(), topic.getMessagesCurrentCount()

Configure JMS server parameters:

edit()
startEdit()
jmsServer = getMBean('/JMSServers/myJMSServer')
jmsServer.setMaxMessagesPerSession(1000)
save()
activate()

These are just a few examples of the WLST commands available for monitoring and managing JMS servers. With WLST, you can automate routine tasks and perform more complex operations on JMS servers with ease.

Monitoring through Third-Party Tools

Third-party tools can be used to monitor and manage WebLogic JMS servers. Some of the popular tools are:

1. Nagios: Nagios is an open-source tool that can monitor network services, hosts, and resources. It can be configured to monitor WebLogic JMS servers and send alerts when certain thresholds are exceeded.
2. PRTG Network Monitor: PRTG is a network monitoring tool that can monitor WebLogic JMS servers and other network devices. It can generate alerts and reports, and provide real-time status updates.
3. Zabbix: Zabbix is an open-source monitoring tool that can monitor network devices, servers, and applications. It can be configured to monitor WebLogic JMS servers and provide alerts and notifications when issues are detected.
4. AppDynamics: AppDynamics is an application performance management tool that can monitor the performance of WebLogic JMS servers and other components of an application. It can provide real-time alerts and notifications when performance issues are detected.
5. SolarWinds: SolarWinds is a network monitoring tool that can monitor WebLogic JMS servers and other network devices. It can provide real-time alerts and notifications, and generate reports on server performance and availability.
