I want to use a command line JMX client to start/stop recording of a stream. I have successfully installed the module ModuleLiveStreamRecord. I can use a JMX GUI client to start and stop recording the stream. However, I am confused as to how I specify the correct parameters on the command line. I modified the code from here [https://www.wowza.com/docs/how-to-set-up-a-command-line-interface-to-wowza-api-to-start-stop-vhost-using-jmx](https://www.wowza.com/docs/how-to-set-up-a-command-line-interface-to-wowza-api-to-start-stop-vhost-using-jmx) to add this capability.

I am using this command line:

./run.sh -jmx service:jmx:rmi://h264web.com:8084/jndi/rmi://h264web.com:8085/jmxrmi -user \*\*\*\*\*\* -pass \*\*\*\*\*\*\* startRecording _defaultVHost_:rtplive/_definst_ rtplive 1.stream /root/foobar.mp4

I get this error when I do this:

“ERROR: doInvoke: javax.management.MBeanException: Cannot find operation recordStream”

Any ideas?

New code (added to code from here [https://www.wowza.com/docs/how-to-set-up-a-command-line-interface-to-wowza-api-to-start-stop-vhost-using-jmx](https://www.wowza.com/docs/how-to-set-up-a-command-line-interface-to-wowza-api-to-start-stop-vhost-using-jmx), and I’m omitting things like where I defined CMD\_STARTRECORDING)

```auto
			else if (args[argOffset].equalsIgnoreCase(CMD_STARTRECORDING))
			{
				System.out.println("Record: #1) " + args[argOffset]+" #2) "+args[argOffset+1]+" #3) "+args[argOffset+2]+
							" #4) "+args[argOffset+3] );
				AppConextName context = new AppConextName(args[argOffset+1], true);
				String connectsName = MBEANNAME+":vHosts=VHosts,vHostName="+context.vhostName+",applications=Applications,applicationName="+context.appName+",applicationInstances=ApplicationInstances,applicationInstanceName="+context.appInstName+",name=ApplicationInstance";
				ObjectName connectsObjName = new ObjectName(connectsName);
				// pass 0 and true as second and third arguments
				Object[] arguments = {args[argOffset+2], "0", "true", args[argOffset+3]};
				String[] signature = {"java.lang.String", "int", "boolean", "java.lang.String"};
				[B]doInvoke(connection, connectsObjName, "recordStream", arguments, signature);[/B]
			}

```

Here is a screenshot of the GUI JMX client which shows the operations available and clearly one of them is marked as “recordStream”.

I’m really not sure, but I noticed your command line says “startRecording” but the screen shot shows an operation “recordStream”

The problem is that you are not going deep enough into the tree. you are stopping at appInstance instead of going to module/instance.

The error is different. You are looking in the right place now but the method is wrong.

It looks like you are only passing 4 args to the recordStream method. If you haven’t modified ModuleLiveStreamRecord from the LiveStreamRecord package then it is expecting 7 args.

With the following change

```auto
	if (args[argOffset].equalsIgnoreCase(CMD_STARTRECORDING))
	{
		System.out.println("Record: #1) " + args[argOffset]+" #2) "+args[argOffset+1]+" #3) "+args[argOffset+2]+
							" #4) "+args[argOffset+3] );	
		// pass 0 and true as second and third arguments
		[b]final Object[] arguments = {args[argOffset+2], 0, true, args[argOffset+3], true, true, true };[/b]
		final String[] signature = {"java.lang.String", "int", "boolean", "java.lang.String", "boolean", "boolean", "boolean"};
		doInvoke(connection, connectsObjName, "recordStream", arguments, signature);
	}

```

Before doing this you have to publish a live stream or start a MediaCaster stream in StreamManager. Then the stream, the application and tat application instance ( _definst_ ) will exist.

The problem is that command by itself does not start the application instance. Run this command first:

```auto
java -cp . JMXCommandLine startAppInstance "live/_definst_"

```

That will start _defaultVHost_ and the application/appInsance

Richard,

Yes, I named the switch for the command line that, but I do send the correct thing (“recordStream”), AFAICT, to the jmx server.

I think what I would like confirmation on more than anything is whether this is correct in my switches:

_defaultVHost:rtplive/definst_

_In this code:_

 

_```auto_

_AppConextName context = new AppConextName(args[argOffset+1], true);
String connectsName = MBEANNAME+":vHosts=VHosts,vHostName="+context.vhostName+",applications=Applications,applicationName="+context.appName+",applicationInstances=ApplicationInstances,applicationInstanceName="+context.appInstName+",name=ApplicationInstance";
ObjectName connectsObjName = new ObjectName(connectsName);_

_```_

 

_I believe this is the correct way to address the module installed in the conf/rtplive/Application.xml file._

_xrd@xrd:~$ grep -i record /usr/local/WowzaMediaServer/conf/rtplive/Application.xml_

_ModuleLiveStreamRecord_

_Can anyone confirm this?_

_I’m going to remove all the other functionality of this java program and then post the complete file to see if that provides more context for the problem._

_Thanks,_

_Chris_

I stripped the file down to what is below. If I run with this command line I get this:

Anyone interested in installing this module and seeing if it works for them using the parameters I specified? I am thinking there is something related to the parameter:

“_defaultVHost_:rtplive/_definst_”

Roger,

Thanks for your help.

I think I am closer. I put a line to print out the “Object Name” inside my code (on line 233). When I run it, I get this now:

```auto
Using: WowzaMediaServerPro:vHosts=VHosts,vHostName=_defaultVHost_,applications=Applications,applicationName=rtplive,applicationInstances=ApplicationInstances,applicationInstanceName=_definst_,modules=Modules,module=ModuleLiveStreamRecord,name=Instance
ERROR: doInvoke: javax.management.ReflectionException: Cannot find method recordStream with this signature

```

So, still have an issue. But, if I look at the JMX console and view the string inside Object Name, I see this:

_WowzaMediaServerPro:vHosts=VHosts,vHostName=defaultVHost,applications=Applications,applicationName=rtplive,applicationInstances=ApplicationInstances,applicationInstanceName=definst,modules=Modules,module=ModuleLiveStreamRecord,name=Instance_

_Which is exactly the same as what I get when I print it out inside my java app._

_WowzaMediaServerPro:vHosts=VHosts,vHostName=defaultVHost,applications=Applications,applicationName=rtplive,applicationInstances=ApplicationInstances,applicationInstanceName=definst,modules=Modules,module=ModuleLiveStreamRecord,name=Instance_

_Enclosed is the screenshot of where I am looking inside the JMX console. And, I can see that there is an operation “recordStream” exposed there, but the app says “Can’t find method…”_

More specifically it says “cannot find method with signature.”

I’m thinking I am getting closer. If I run the stopRecording command (after correcting a typo…), no complaints.

I changed the signature line in the code so the code has a signature like exposed in the JMX console.

But, now I get:

_“ERROR: doInvoke: javax.management.MBeanException: Exception invoking method recordStream”_

Roger,

Does it show that I have a background in Perl and Ruby, languages which do that for me? 🙂

Thanks so much for your help. All is well now!

Nice write up,

however i get the error

Error: Could not find or load main class JMXCommandLine

when i schedule a cron job, but if i run the command at shell all it ok

and yes i have compile the files i get two files JMXCommandLine.class & JMXCommandLine$AppConextName.class that are placed in the /usr/ directory

command used

/usr/./jmxcl.sh -jmx service:jmx:rmi://localhost:8084/jndi/rmi://localhost:8085/jmxrmi -user admin -pass admin recordStream _defaultVHost_:test/_definst_ test /usr/local/WowzaMediaServer/content/test.flv true true true

where am i going wrong?

Maybe you could be so gentle and share the final code of your application and command lines to control?

Now seems it’s working, but I guess this script is for Wowza 2.0. Can it work with Wowza 1.7 ?

I’m not able to configure the starting line.

LiveStreamRecord works

with

And I’m getting error
