Not all statefull events are displayed.

I’m trying to develop my own plugin based on the EventAndStateViewer example.

I would like to query the current status of cameras, recording servers, etc. and send a message if a component fails.

As soon as I select a subscription for cameras, the current status is displayed in the State Viewer.

However, if I specify “Database Storage Area Available and Database Storage Area Unavailable” as the EventType, the current status is not displayed in the StateViewer. It is only displayed when the event occurs. In addition, the “Database Storage Area Available” event is never triggered.

After searching the source code, this event is assigned to a statefull (DatabaseDisk) group.

Is this correct or is this a bug in the SDK?

thanks in advance

Hi Ralf,

Your observations are correct.

In short, when EvS starts it asks for some of the states, some of the components and generates “fake” events based on that state. Unfortunately, DB storage area is not among these.

Hi Petar,

Thanks for the quick response.

Do you happen to know how I can query the status for the first time when starting my plug-in?

thanks
