I have a few web monitor inputs configured on a Heavy Forwarder to ping a url every minute. I then set up alerts on this to alert me if I get less than 25 pings with response_code=200 within 30 minutes. I have been getting a ton of false alerts with these. Most of the time when I check the alert, I still see a high number of successful pings for the past 30 minutes that would cause the alert NOT to fire. Every now and then there are actually a low enough number of successful pings to fire the alert, but when I check my url everything is fine. Is there any reason that there would be a delay in the HF sending these pings every minute?
