1)
Anomalies badge going "up" (above 0) basically indicate that there's something anomalous / out of the ordinary going on with your machine.
I think that's pretty obvious in the first snapshot - all was "calm" and at certain point the CPU usage spiked quite a lot. From what I see it used to be somewhere between 0 (idle) and ~15%,
and now it's 24%.
The items on the right are indicators what else has changed at the same time. I see spikes in network thruput, disk I/O, CPU usage etc - so that VM basically started doing something out of the blue,
most likely after it got some information over the network.
That's what I see on that first snapshot

As to the "not calculated yet" - Is that only for the Anomalies badge, or for other badges as well? I think for Workload you should see the "Normal X-Y", cause there are DT indicators on the snapshots
(that's the small-blue-things above the each of the 4 green stripes in the "workload" section.It tells you the range where each value runs over time)
What it means is that although there's data for 1 month, the system haven't been able to find a valid fit/trend within the available data, in order to tell you what should be normal
