Last time used a Thing

[tenegabi]

Hello there,

Is a way to see when was last used a Thing? Or a service? I try to search on Internet and in Thingworx, but I can't find anything about that.

Hello @tenegabi ,

If you want to check any changes that might have happened, you can check in the change history tab of the respective Thing.

Hello @bchaudhary ,

Not this options, I know already this, I want to know when was run last time a Thing, not last modify a service.

What do you mean by "used", when a property value was updated, or a service called? Or just when someone "looked" at it?

There is no way to track if a Thing was returned by a query or if someone just looked at it.

For editing access you can use subscriptions (on DataChangeEvent) and custom logging, Value Streams or the Audit Subsystem.

Hello @Rocko ,

I have a lot of Things, one of them are part an application on my company, I have a task to see what application is unused for more 90 days, if is unused more that 90 days we will delete the application. I don' know if I explain good.

Adding to the previous options, you could add a DATETIME property named "lastAccess" to your thing. In the service, you would update this property with the current date. So whenever the service is called, the property will be updated. This way you can track when the service(s) of that thing were called last.

Ok, I understand, something else from Thingworx is do not exist?

Audit Subsystem, as I mentioned.
