The collector capacity is based on the brick size. The data source that you can add to a collector is depended on the capacity of the collector (VMs and flows).
You can scale up each collector to Extra-Large size. You can add multiple data sources to a collector based on the supported collector capacity. However, you cannot add same data source to multiple collectors.
Scaling up Scenarios for the Collectors
| Scenarios | Action to perform |
|---|---|
| 2000 VMs in a vCenter | Install one medium collector VM. Add the vCenter to this collector. |
| 1000 VMs in vCenter1 and 2000 VMs in vCenter2 (all of them are in one data center) | Install one medium collector VM. Add both vCenters to this collector. |
| 1000 VMs in vCenter1 (data center1) and 2000 VMs in vCenter2 (data center2) | Install one medium collector VM in each data center. Add vCenter1 to a collector VM in same data center and Add vCenter2 to a collector VM in its data center. |
| VM count exceeds 4000, active flows exceeds 2.5 Million. | Convert your collector VM from MEDIUM to LARGE. See Increase the Brick Size of Your Setup. |
| 9,000 VMs in vCenter1 without flows (data center1). | Install one large collector VM. Add this vCenter to the collector. |
| VM count is less than or equal to 10000, but the active flow exceeds 5 million. | Convert your collector VM from LARGE to EXTRA-LARGE. See Increase the Brick Size of Your Setup. |
| Two vCenters, vCenter1 has 10000 VMs and 9 million active flows, and vCenter2 has 10000 VMs and 4 million active flows. | Install one |
| One vCenter that runs 10000 VMs and 9 million active flows. | Install one EXTRA-LARGE collector and add the vCenter to the collector. |
