How to get number of views count for post in Discussion List in SharePoint

If you search for a discussion board post that's been in the system for a little while, and hover over the search result, you'll note that there is an OOB view counter that appears. This data is not live, and is updated via the usage analytics jobs, which I think are run once a day. If you think these restrictions are still workable, you can access the data via a rest call to the search service:

https://somehost.sharepoint.com/_api/search/query?querytext='path:"https://somehost.sharepoint.com/Lists/Discussion Board List/somepost"'&rowlimit=10

In the results of the REST call, look for the ViewsRecent and ViewsLifetime fields.

Create a column in list, and set 0 as a default value in the column. Now from where you are viewing the item. write a function to add the value by 1 in that column. Using this way you can count the no of view per item.
