When to Scale Your Monitoring
- You have a large number of Hosts
- You have several datacenters that span across different geographic locations
- You have networks that have secured zones or firewall rules to segregate Hosts
The host where Opsview is first installed is called the Opsview Monitor Orchestrator Server. This host has all the necessary software packages installed so that it can function as a single Opsview system, but you can separate out the functional components onto other hosts to spread the load and decrease latency.
Opsview uses Collectors to handle the execution and collection of results. For additional failover and load balancing capabilities, Collectors may be grouped together to form a Cluster. Each Host in Opsview is assigned to a Cluster. The Host will be actively checked by any Collector in that Cluster.
