System.perspective.getSessionInfo()

Ignition
1

Hi guys, as I know that Ignition gateway has a page called Perspective Sessions. May I know that it is possible to display all the data there in my project and display in a table format. From what I research I know that there is a script called ( System.perspective.getSessionInfo() ) can do it but I had try many times already it still cant work for me. May I know that anyone here have the example of these script.

Thanks in advance

	sessions = system.perspective.getSessionInfo()
	data = []
	for session in sessions:
		keys = session.keys()
		newRow = []
		for key in keys:
			newRow.append(str(session[key]))
		data.append(newRow)
	self.getSibling("Table").props.data = system.dataset.toDataSet(keys, data)

Of course it will fail since the mentioned fucntion needs to be executed in the CS scope.
Just put in a button or somewhere within the the client or session. Gateway is not the place for it!

Thanks, It worked, one more doubt Is there any way that I can get all the perspective project alone. I don’t want any vision project list.

system.perspective.getProjectInfo() only returns info about perspective projects.

Also, it is available in the gateway scope, so I would expect it to execute just fine from a gateway script.

Perhaps @cmallonee can give a bit more information?

Thanks for the information, I tried that, its showing some errors. Can someone help me on this I want to get all perspective projects from the gateway(atleast project names.). Is there any way to do that?
