The remote collector node
The remote collector node is a continuation of the vCenter Operations Manager 5.x installable concept around having a standalone collector for remote sites or secure enclaves. Remote collectors do not process data themselves; instead, they simply forward on metric data to data nodes for analytics processing.
Remote collector nodes do not run several of the core vRealize Operations components, including the following:
- Product UI
- Controller
- GemFire locator
- Analytics
- Persistence
As a result of not running these components, remote collectors are not members of the GemFire federation, and although they do not add resources to the cluster, they themselves require far fewer resources to run, which is ideal in smaller remote office locations:
An important point to note is that adapter instances will fail over to other data nodes when the hosting node fails, even if HA is not enabled. An exception to this is remote collectors, as adapter instances registered to remote collectors will not automatically fail over.
