Recently started at a new place of employment and each day we are getting hundreds of NPM e-mails reading 'Errors Reported This Hour Are 0'. We do have an alert created however after looking at it the defined threshold is greater than 999 for both received and transmit errors as shown in the screenshot. This seems to happen primarily on two switches in our environment that are Cisco 3840-48 port and it happens on many different interfaces both gig and ten gig.
Any ideas on what is causing alerts to go out even though there are no errors?
