SQL Audit Log In Repeats Results I'm using SSMS's Audit feature to see who's successfully logging in and logging out of the server and I'm currently testing it in a server in which only I have access to it. 
I used for SUCCESSFUL_LOGIN_GROUP and LOGOUT_GROUP for my server audit specifications.

Every time I view the audit logs, why is it that I see that my account constantly logging in and out of the server when in reality I didn't even log out?
It looks like you're using SQL Server Management Studio (SSMS) to query your server. SSMS will open one session for your query tab, plus another session to populate the Object Explorer. 

By default, SSMS also has IntelliSense enabled. IntelliSense will make a high volume of very quick database queries in order to validate your query against database schema metadata. Each of the queries will involve a login to the server. I suspect this is responsible for the majority of what you are seeing. One quick way to verify is to disable IntelliSense on your SSMS. Alternatively, you could run you test from another tool that is less "chatty" with the database (such as the SqlServer PowerShell module or sqlcmd CLI).
