AppFabric had a status of DOWN however I was still able to view SharePoint pages etc (though had lots of errors in events viewer). I now have AppFabric UP (In windows services Application Fabric is also running) and wanted to know if SharePoint is making use of it. How can I check this as when it was DOWN SharePoint still appeared to work?
There are couple of indications whether DC is working or not?
- If DC is not working then user will face the issue with authentication, Users will get access denied, unexpected errors.
- News Feed is not syncing properly or saving the feed data.
- User can see long wait time for page load, image dropped or time out issues.
- Most of social features either stop working or throwing errors with correlation id.
Here is good guide to validate the DC: https://blogs.technet.microsoft.com/filipbosmans/2015/09/07/how-to-check-for-issues-with-distributed-cache-and-the-script/
