Working with the FortiDDoS Monitor graphs

The FortiDDoS system records data points for monitored thresholds every five minutes. The data point is the highest rate observed in any one second during the five-minute window.

Maximum values recorded

The FortiDDoS graphs are plots of data points. The reporting framework uses resolution periods to fit data points in time-based graphs. In a graph with a five-minute resolution period, the graph is based on a plot of the rates or counts recorded for the regular five minute window. In a graph with a one hour resolution period, the graph is based on a plot of the rates or counts for the highest rate among the points recorded in a one-hour window—in other words, the highest rate among the twelve five-minute windows reported in the hour.

The following table lists resolution periods used for report periods.

Data resolution periods
Graph Period Resolution Period
1 hour 5 minutes
8 hours 5 minutes
1 day 5 minutes
1 week 1 hour
1 month 3 hours
1 year 45 hours

Note: The data displayed in a graph is current as of the time the last data point was written. For example, a 1-hour graph with a 5-minute resolution is current as of the time the last 5-minute resolution data point was stored. Traffic in the most recent 0-5 minutes might not have been registered yet. Similarly, for a 1-year graph with a data resolution of 45 hours, data for the last 0-45 hours might not have been registered yet.
