1.) If I assign an Alert to a Custom Group does it look at each device in that group individually and alert on them or does it look at the consolidated metrics and report on the group as a whole?
2.) Regarding the “Trend Settings” tab, when using Same Hour, or Hour rolling Average, when does the Alert fire, at the end of that hour? If so I assume that would be a bad choice when you’re trying to catch an outage?
3.) Regarding the “Trend Settings” tab, minute Rolling fires based off the configuration under Alert Settings?
4.) 2nd to last question is there a way to alert us when the metrics exceed the mean but not let those random one off spikes cause the mean to go up, and potentially miss the next spike. For example we
have an issue with Rcv Wnd Throttles Out over the last 2 weeks is showing an average of 2,063 a day. The issue is we had 2 days with big spikes; 5,356 and 13,254. If you exclude those the daily average is only 202 Rcv Wnd Throttles Out a day. Is there way to exclude the extreme spikes but still report on them when they happen?
5.) When you configure the “Trend Settings” tab what does that apply too on the “Alerts Settings” tab? Obviously it probably has something to do with “Percentage of trend” but does it define the mean, median, or standard deviation on the 1st drop down?
