If your CertsModelContainer is a DbContext, you can cast it to an IObjectContextAdapter in order to access the ObjectStateManager.

For example:

using (CertsModelContainer db = new CertsModelContainer())

    {
        Console.WriteLine(string.Format(
            "ObjectStateManager.ObjectStateManagerChanged | Action: {0}, Object: {1}",
            e.Action,
            e.Element));
    };
}
