ScienceLogic Settings/HA API is one of 80 APIs that [ScienceLogic](https://apis.io/providers/sciencelogic/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Settings/HA. The published artifact set on APIs.io includes an OpenAPI specification, an API reference, and API documentation.

High Availability (HA) provides a way to minimise the effects of hardware failure, by configuring two Skylar Compliance appliances in a cluster. Under normal operating conditions, the primary cluster member is active and the secondary is in standby mode; the active appliance performs all network operations, and replicates all settings and device configurations to the standby appliance. Skylar Compliance replicates data both incrementally (for instance, just after a backup is retrieved from a device) and by performing full synchronisations on a regular basis. Should the primary member become unavailable because of hardware failure, other network problem, or losing power, the secondary member will automatically become Active, and carry on as normal. If the primary recovers, it will automatically take over from the secondary and become active. HA does not require the appliance to be installed on the same network, as long as the traffic requirements are met (see below). Software updates and upgrades are managed at the cluster level; updating the active appliance will automatically update the standby appliance. ### Requirements * High Availability is a separately licensed feature. * Only appliances of the same model can be clustered; appliance must be running the same software version. * Cluster members must be able to communicate over HTTPS to exchange heartbeat information and data synchronisation; TCP/443 traffic should be permitted bidirectionally between the appliances.
