8.3 Remote Collectors
VMware recommends deploying remote collectors (RCs) in either of these cases:
• If a vRealize Operations Manager cluster must analyze data from remote sites connected by low-bandwidth or high-latency communication links.
• If the infrastructure to be monitored is in a secure zone and protected by a firewall.
Remote collectors can be deployed in one of two resource profiles: standard or large. The configuration for each size is shown in
Table 5.
Disk space is not important to a remote collector, because collection data is stored in memory. The virtual disk can be left at the default size (thin provisioning is also acceptable).
Design Considerations
If monitoring targets are in a secure zone or on the opposite end of a WAN link, consider deploying a remote collector to reduce the number of firewall rules required and reduce load on the WAN.
