Plots are available for three metrics:
| rtt | Round trip time for DNS request/responses |
|---|---|
| loss % | Percentage of requests which didn't get a response Only plotted for intervals when there were 10 or more data points |
| count | Number of DNS request/response pairs observed |
What do the `submit' buttons do?
| Plot | Plots the requested data for the specified number of days, beginning with the start date |
|---|---|
| > | Increments the start date by the number of days, then plots from the new start date. For example, if the number of days is 7, > will plot the next week's data |
| < | Decrements the start date by the number of days, then plots from the new start date |
| | | Sets the start date to the Saturday before the start date, then plots from that date |
| Help | Displays this `information' page |
