How to check if the MQ listener is running?

To check if the MQ listener is running, you can do so in the following ways:

1. Check if the MQ listener process exists: You can use command line tools (such as Task Manager in Windows or the ps command in Linux) to verify if the MQ listener process exists. In the MQ management interface, there are usually one or more processes associated with the listener.
2. Check if the MQ listening port is open: MQ listening usually occupies one or more specific ports. You can use network tools (such as the Windows netstat command or Linux lsof command) to check if these ports are in listening state.
3. Access the MQ management interface to check the listening status: MQ typically offers a management interface that can be accessed through a web browser. Within the interface, you can view the status of the MQ listener, including whether it is activated, the port number being listened on, and other related information.
4. Check the MQ listener logs: MQ typically generates some log files that record information about the listener startup and operation process. By reviewing these log files, you can understand the status of the listener startup.

In conclusion, you can check whether the MQ listener is running by examining the processes, ports, management interface, and logs.
