This is quite simple, if you have understood HangFire & SignalR concepts

You can simply place a function inside your Hangfire Job to call SignalR function inside it, to get state of Hangfire.IO and to send message to all users.

Suppose my recurring job name is : FullThings

Now when HangFire call this function(FullThings), place SignalR Hub Instance inside it and call required function, something like this

public string FullThing()
{
   hub = GlobalHost.ConnectionManager.GetHubContext<ClientPushHub>();
   hub.Clients.All.SendAlertAboutJob("Started");
   //Some code
     
}
