Groundwork Open Source

GroundWork Open Source, Inc. builds GroundWork Monitor, an open-source-based IT and network monitoring platform for hybrid infrastructure, assembling Nagios Core, Telegraf, InfluxDB, and Grafana into a unified availability, event, and metrics monitoring product. Its integration layer, the Transit Connection Generator (TCG), exposes a Controller REST API and a Go SDK for feeding host/ service inventory, metrics, alert events, and downtime windows into the GroundWork Foundation server. The platform is self-hosted; all source lives on GitHub under the gwos organization (TCG, Nagios Core, Grafana, and Telegraf forks). Surfaced as a portfolio company of Canaan Partners and enriched here from its live GitHub org and published Swagger 2.0 API specification.

Groundwork Open Source publishes 8 APIs on the APIs.io network, including agent API, alert API, connector API, and 5 more. Tagged areas include Company, Monitoring, Network Monitoring, IT Infrastructure, and Observability.

Groundwork Open Source’s developer surface includes authentication, documentation, API reference, and 14 more developer resources.
