Identify which database raised a publish event

Knowing which database raised a publish:end or a publish:end:remote event can be very useful when you want to update the caches on, for example, remote Sitecore CD instances.

To identify the database that raised a publish:end event, run this code:

Public void OnPublishEnd(object sender, EventArgs args)
        {
            var Publisher publisher =
Sitecore.Events.Event.ExtractParameter<Publisher>(args,
0) as Publisher;
            var db = publisher.Options.TargetDatabase.Name;
        }

To identify the database that raised a publish:end:remote event, run this code:

Public void OnPublishEndRemote(object sender, EventArgs args)
        {
            var publishEndArgs = args as Sitecore.Data.Events.PublishEndRemoteEventArgs;
            var dbs =
Sitecore.Configuration.Factory.GetDatabases().Where(db =>
db.RemoteEvents.EventQueue.Name == publishEndArgs.EventQueueName);
        }
