Hello, I’d like to create a custom module I’ve followed the instructions of the Wowza IDE Guide [https://www.wowza.com/uploads/developers/WowzaIDE\_UsersGuide.pdf](https://www.wowza.com/uploads/developers/WowzaIDE_UsersGuide.pdf) and the module compiles and start the server perfectly but… two questions… - Why the server don’t start 8088 port for Streaming Engine Manager? - Why I don’t get any info in the console or the log files with the following code requesting a live stream? ---

To answer your questions: > > Why the server don’t start 8088 port for Streaming Engine Manager? Ensure that you don’t have port 8088 blocked in your local firewall and check that the [manager is started](https://www.wowza.com/docs/how-to-install-and-configure-wowza-streaming-engine#startManager). > > Why I don’t get any info in the console or the log files with the following code requesting a live stream? Did you setup the module in your Application.xml (under ) similar to the following (as obtained from the user guide): ```auto Live Live Module com.mycompany.wms.module.live ``` Is your .jar file also included in the [install-dir]/lib directory? ---

Hi, Port 8088 is for the Wowza Streaming Engine Manager which runs as a separate service to the main server. You should be able to start it from the command line by going to /Library/WowzaStreamingEngine/manager/bin and running sudo ./startmgr.sh. You can also set it to run continuously by starting it using the launchctl command. Please refer to the Users Guide for detailed instructions. The Manager is a basic web server so when it is not being used in the browser, it will just sit quietly waiting. When you start the main server from the command line, you will be able to connect to it from the manager. You may notice some errors in the manager if you do shut down the main server and are on one of the pages that automatically refreshes. Roger. ---

Thanks matt\_y, The module now is working and I receive all the messages in the console window, the problem was on the Application.xml wrong module name. But the 8088 port isn’t started, here is the console log, it seems that it didn’t try to start it. ```auto Configure logging: file:///Library/WowzaStreamingEngine-4.0.3/conf/log4j.properties INFO server server-start Wowza Streaming Engine 4 Developer Edition (Expires: oct 18, 2014) 4.0.3 build10989 - INFO server comment - Server License Key: EDEV4-XXXXX-XXXXX-XXXXX-XXXXX-7d9AG INFO server comment - Maximum Connections: 10 INFO server comment - Maximum Incoming Streams: 3 INFO server comment - Transcoder Streams Available: Transcoder Not Available (osx-64) INFO server comment - nDVR Available: Yes INFO server comment - DRM Available: Yes INFO server comment - HTTP Origin Available: No INFO server comment - Push Publish Available: Yes INFO server comment - REST API Available: Yes INFO server comment - Hardware Available Processors: 4 INFO server comment - Hardware Physical Memory: 10970MB/16384MB INFO server comment - Hardware Swap Space: 1386MB/2048MB INFO server comment - Max File Descriptor Count: 10240 INFO server comment - Open File Descriptor Count: 85 INFO server comment - OS Name: Mac OS X INFO server comment - OS Version: 10.9.2 INFO server comment - OS Architecture: x86_64 INFO server comment - Java Name: Java HotSpot(TM) 64-Bit Server VM INFO server comment - Java Vendor: Apple Inc.

Double check ports and firewall settings. Make sure nothing else listens on 8088. Also see this [https://www.wowza.com/docs/how-to-find-your-way-around-wowza-streaming-engine-manager](https://www.wowza.com/docs/how-to-find-your-way-around-wowza-streaming-engine-manager)
