4.4.5 Remote Collectors
VMware recommends deploying remote collectors in either of the following 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
Figure 7. 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).
As a design consideration, 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.
