vRealize Operations (vROps) provides native vSAN support with multiplay dashboards for proactive alerting, heat maps, device and cluster insights, and streamlined issue resolution. Also vROps provides forward trending and forecasting to vSAN datastore as well as any another datastore (SAN/NAS).
vSAN 6.7 introduced "vRealize Operations (vROps) within vCenter". This provides end users with 6 dashboards inside vCenter console, giving insights but not actions. Three of these dashboards relate to vSAN: Overview, Cluster View, Alerts. One of the widgets inside these dasboards displays "Time remaining before capacity runs out". Because this provides only some very basic trending information, a full version of the vROps product is still required.
"vRealize Operations (vROps) within vCenter" is included with vSAN Enterprise and vSAN Advanced.
The full version of vRealize Operations (vROps) is licensed as a separate product from VMware vSAN.
