In MySQL, we can use the sys.ps_is_account_enabled() function to check whether Performance Schema instrumentation for a given account is enabled.

The function returns YES or NO, depending on whether or not the instrumentation for the given account is enabled.

sys.ps_is_account_enabled(host,user)

In this case, Performance Schema instrumentation is enabled for the user barney on localhost.
