The Health dashboard is a real-time operations view of the NEXOS CORE platform host itself — the server running your instance. It reports live host metrics (CPU, memory, disk, network, uptime), lets you define and probe the dependencies your instance relies on, and lets an operator restart core system services from the UI. Open it at /settings/health.
This monitors the NEXOS CORE host, not your clients’ infrastructure. For monitoring client endpoints, see RMM. This is an operator/admin tool.

​
When to use it

  • Confirm the host is healthy — CPU/RAM/disk pressure, load average, uptime.
  • Check whether key dependencies are reachable (web front end, database, others).
  • Diagnose a slowdown — inspect PostgreSQL cache-hit ratio, connections, and slow queries.
  • Restart a core system service without SSH.

​
Host metrics

Live CPU usage and load averages, memory and swap, disk usage, per-interface network info and aggregate I/O, plus OS, kernel, and uptime.

​
Component probes

Define “ecosystem components” and probe them concurrently, each returning a status and latency. Four check types:
  • HTTP — a GET with a short timeout (2xx/3xx healthy; auth-style 401/403/405 still count as “up”).
  • TCP — a port connect.
  • PostgreSQL — a version check.
  • Process — systemctl is-active (falling back to a process match).
Click a component for extended metrics — for PostgreSQL: database sizes, connections, cache-hit ratio, and top slow queries (when pg_stat_statements is available); for HTTP: average latency, status, and headers.

​
Service management

View and restart a fixed whitelist of core services (e.g. nexusos-psa, postgresql, nginx, docker) directly from the dashboard. Restarts are audit-logged.

​
Good to know

  • Most host metrics are Linux-only (they read /proc and /etc/os-release); disk also works on macOS.
  • Service restart requires systemd with passwordless sudo, and only the whitelisted service names are permitted.
  • The PostgreSQL probe checks the NEXOS CORE application database.
