hi team,
have a question from a customer. Is there a recommendation on the smallest polling interval that Harvest can be configured for performance collections?
Reason behind the question: the default interval is sometimes not granular enough for the NTAP support team to identify the roof cause for a performance issue. The customer would like to understand if they can shorten the collection interval, but at the same time, they don't want to place too much overheads on the controllers.

@hexed tinsel Do you know the desired interval for the customer's perf collector? Several factors affect this:
- If the data collection process is extensive and takes longer than the set interval, reducing the interval may not yield any benefits.
- The Prometheus scrape_interval should be equal to or shorter than collector interval.
- This will increase load on ONTAP; the overhead can only be determined through trial and error.
Some customers have tried a 10-second interval, but it may not suit all environments.
