Which three factors determine the size of vRealize Operations deployment?

Number of Objects

vRealize Operations sizing is fundamentally driven by how many infrastructure and application objects (VMs, hosts, datastores, etc.) are being monitored - each additional object consumes CPU, memory, and storage resources on the cluster.

Number of Agents

When using Application Remote Collectors, the total count of agents (for OS and application‑level metrics) per node directly affects capacity planning, as each agent connection incurs processing and storage overhead.

Number of Metrics

The volume of distinct metrics collected (across all adapters and agents) determines database size and I/O load; sizing guidelines specify maximum collected‑metric counts per node to ensure performance.
