I have downloaded ULS viewer, But i am unable to view the event, do i need to configure something to view the Event log?
As Others mentioned, ULS viewer provides a simplified view of ULS log files in SharePoint 2013 that supports aggregation, filtering, sorting, highlighting, append, and more.
But you cannot check / hook the event logs in it. If you want to live monitoring of your farm( as they have farm option in it, means multiple servers at same time). then you have to configure it that way.
Honestly, it is really hard to view / hard understand the logs, in live stream.I configured it for live stream and i am done after loosing alot of hairs.
There are other monitoring Tools which will capture the event log i.e MSFT own product SCOM which we are using.
