How to show a message in frontend what is going on backend?

Hi, Making a call from client side in x intervals is not a good choice. it will increase the system load when number of users increase. I would suggest to use SignalR to push the messages from server side, so in a every action you can asynchronously trigger an event, then subscribed clients can receive an messages, then you can display it. if you have limited users , then use pusher or ably free versions with limited messages per day. good luck
