Set up High Availability pools with multiple active and standby servers (HA multi-clustering)
This topic applies only to SolarWinds Observability Self-Hosted.
Set up HA pools with multiple active and standby servers for your Additional polling engines. See also Set up a SolarWinds Platform High Availability pool. You can also use the SolarWinds Platform API to set up HA multi-clustering.
- HA reports pool status as partially operational even though all active members are healthy.
- A VIP or Virtual Hostname can be assigned to a HA Pool with only two servers and cannot be assigned to individual pool members.
Requirements
- All polling engines must have the same version
- An activated SolarWinds Observability Self-Hosted Enterprise Scale license

When the HA pool has more than two members, the VIP and Virtual Hostname fields are disabled.
