I created a new alert this morning, in order to let me know when the traffic gets too low i.e. when it drops below 300 page viewed in an hour. This hourly alert is very simple, indeed. Nevertheless, email@example.com keeps sending me alert e-mails stating that no page views were viewed at all.
Fortunately, these fired alerts proved to be fake: today traffic is as high as it was yesterday, with more that 10.000 PV per hour.
Could someone help me to understand this strange behaviour?
Couldn't be a problem with the time zone? Perhaps the alert system checks the wrong hourly range (i.e. not the previous one but the current one), thus resulting in a mathematically zero PV, being data not already rose in the report suites.
