This is a VPS agent endpoint at https://agent.dbhost.app/health, not part of the control plane API. It requires Authorization: Bearer <API_KEY>. Use GET /healthz for unauthenticated liveness checks.

Returns detailed health and capacity metrics for PostgreSQL, PgBouncer, server disk usage, managed PostgreSQL data size, server memory, load averages, and current PgBouncer pool/client state.

Response notes

memory and load are nullable and may be omitted if the VPS cannot collect them.
pgbouncer_pools excludes the PgBouncer admin database and focuses on managed tenant pools.
pgbouncer_clients reflects current live PgBouncer client sessions, not the historical connection log stored in the control plane database.

Status values

Status	Meaning
`healthy`	Both PostgreSQL and PgBouncer are running
`degraded`	One or both services are down, or the agent could not collect detailed PostgreSQL capacity metrics
