Just back from half-term and a look at my ZD Dashboard Usage Summary shows a minor gui curiosity...
For "# of Rogue Devices" shouldn't the 24hr period include the 1hr period?
So am I seeing
1hr info and then the previous 23hr info or...(to confuse you)
1hr info and then 25hr less the last hour...(I'll stop there)!
If max value occurs in last hour the 24hr values should also reflect that maximum.
