VAST Data subnetmanager API is one of 126 APIs that [VAST Data](https://apis.io/providers/vastdata/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include subnetmanager. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and SDKs.

The subnetmanager monitors an OpenSM service. Clusters operating in larger IB networks must have an OpenSM service configured on some of the CNodes in the cluster. The OpenSM services running on those Cnodes are critical for the data network and need to be monitored. Monitoring is enabled when up to two IPs of CNodes hosting the OpenSM service are registered. The state and if applicable, failure reason, can be retrieved from the registered CNodes.
