I have set up a high packet loss alert that looks like this:

My issue is that these alerts are not accurate at all. when i get an alert (via Slack), i immediately ping (from both my computer and the polling engine) the affected FW and get responses back every time with little latency. What is also weird, is that these alerts take the same amount of time to reset - 12 minutes, the same amount of time the condition must exist for. this happens for every. single. one.
this is my reset condition:

Why would this happen? i can't rely on these alerts because of how inaccurate they are.
