Real Impact of MS Performance Counters

; have been collecting information about 20 performance counters (memory, IO,
cpu, SQL) that refresh every 15 seconds; would that have any performance hit
in the server? what are best practices when collecting information via
performance counters?
ThanksCollecting these counter values at a 15-second interval should have
absolutely no performance impact. (If on the other hand for however small
chance it does have an impact, your machine is greatly under-spec'ed). No, I
wouldn't worry about any performance impact at all.
