	QuantaStor supervises all three, re-~~checking~~ them every ten minutes, and restarts telegraf whenever the collection configuration changes. ~~It also~~ '''~~pauses~~ collection ~~during some configuration changes~~''' ~~-- it stops telegraf while it reconfigures~~ and restarts it afterwards ~~-- which leaves a short gap in every chart. A gap of a few seconds around a pool or network change is normal~~.		QuantaStor supervises all three and re-checks them every ten minutes. Two things it does on its own leave a short gap in every chart, and both are normal:

			* '''It restarts telegraf whenever the collection configuration changes''', which includes any change to the set of devices it collects I/O for -- so creating, growing or deleting a pool or a volume costs a few seconds of samples.
			* '''It stops collection outright for the duration of a Ceph cluster create or destroy''', and restarts it afterwards.

	Each appliance collects and stores its own statistics; there is no grid-wide database. A Grid View tile is drawn from the data on that member.		Each appliance collects and stores its own statistics; there is no grid-wide database. A Grid View tile is drawn from the data on that member.

Qadmin: Rewrite from the product on 6.9.0: full Grid View / Storage System / per-object dashboard reference, statistics database sampling interval and retention, external dashboards, performance alerts. Corrects the Graph/Tiles checkbox names (now Grid Details / System Details) and the claim that the Tiles checkbox shows only tiles; replaces the stale .jpg screenshots (QSTOR-12352)
