Key Resource Manager concepts
- A set of Resource Manager services that provide monitoring
capabilities for a specific network location. Collector services are
deployed into a Control Center resource pool through the
Resource Manager browser interface.
- collector pool
- A Control Center resource pool that is dedicated for use by
one or more Resource Manager collectors; usually, just one.
Most deployments use one collector pool for each distinct network
location, although each collector pool typically includes multiple
Control Center hosts.
- collector pool VIP
- A virtual IP address that is assigned a collector pool, to float
among the hosts that are members of the pool. Resource Manager
services that require a permanent IP address are unaffected by the
status of specific pool hosts. The virtual IP address
is created and assigned through the Control Center
- master pool
- A Control Center resource pool that contains only
the Control Center master host. By isolating the
master host in its own pool and configuring a ZooKeeper
ensemble, Resource Manager services are not
affected when Control Center internal services
are temporarily unavailable. The recommended name
for this pool is master.
- Resource Manager pool
- A Control Center resource pool that runs
Resource Manager infrastructure services and other
key services. This resource pool must be on the same subnet
as the master pool. A Resource Manager pool includes
a minimum of two Control Center hosts. The recommended
name is Resource Manager.
