Sharepoint - SharePoint 2013 Usage reports are empty

Can you please confirm following?

Usage File Creation (typically found C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\LOGS\RequestUsage)

In the logging folder, we need to find a folder called RequestUsage. In this folder, if healthy and working correctly, we will see a *.tmp file and periodically a *.usage file being generated. If there is no file being created in here then the site is not listening for page requests.

If there is no file in here being generated make sure the site has some traffic to it, so browse the site, and check the folder periodically.

RequestUsage folder

The Microsoft SharePoint Foundation Usage Data Import timer job looks in this folder and takes *.usage file and imports the data to the Event Store.

and also this: he Event Store (typically found at C:\Program Files\Microsoft Office Servers\15.0\Data\Office Server)

The Event Store can be a chore to find, because the folder before it consists of a name with a GUID in it. If you look at your server’s shares, you’ll see it in there. In some cases, you can navigate directly from there to folder, but in other cases you cannot and will have to find it manually. Usually, I run a search for this folder by searching the computer for Analytics or EventStore. In the picture below you can see the “Analytics_(GUID)” share.

The Event Store Analytics_(GUID)

Once you find the event store, we want to make sure that it is creating folders with data in them. The folders are names based on their date. Inside the folders, you should find some .log files.

Event Store .log files

Not everything that gets passed from the RequestUsage folder gets put into the Event Store data files. Some of the information does get filtered out.

In the end I deleted the Health and usage service application in "manage service applications" section in Central Admin.

I then re-enabled it by going to monitoring -> Configure usage and Health Data Collection and then checking the Enable usage data collection and enable health data collection check boxes and validating the other information.

The next day I had results.

When in doubt...kick it.
