Built on open, proven infrastructure — not a black box
MonSPHERE isn't a proprietary metrics format wrapped in a dashboard. It's a real Prometheus and VictoriaMetrics stack, orchestrated by 21 purpose-built microservices, deployed with a single Docker Compose file.
Every layer, real and documented
No layer here is aspirational — this is the actual stack running in production and in every self-hosted deployment.
API Gateway
One nginx-fronted unified Gateway routes every client request to the right backend service.
Microservices
A modular monolith compiled into 21 independently deployable service binaries.
Prometheus
The metrics collection and query engine every monitor, exporter, and agent reports through.
VictoriaMetrics
Long-term, cost-efficient time-series storage independent of Prometheus's local retention.
Alertmanager
Real alert routing, deduplication, and grouping — MonSPHERE's alert engine sits on top of it.
NATS
The event bus connecting services — 22 real subjects span auth, monitoring, billing, and audit events.
PostgreSQL
A single shared database across every service — organizations, monitors, RBAC, billing, and audit all live here.
Redis
Session cache, rate-limit counters, and short-lived challenge tokens (MFA, email verification).
Docker
Every service, and the entire dependency stack, ships as one Docker Compose deployment — 28 containers total.
From exporter to incident to dashboard
Agent installs an exporter
The MonSPHERE agent connects over mTLS gRPC and installs/supervises Prometheus exporters via the Docker Engine API.
Prometheus scrapes metrics
Metrics flow into Prometheus, which also feeds VictoriaMetrics for long-term retention.
Alert rules evaluate
Alertmanager and MonSPHERE's alert-engine evaluate thresholds and anomalies against live metrics.
Incidents & notifications fire
incident-service opens a tracked incident; notification-service and webhook-worker deliver it to Slack, PagerDuty, email, or a custom webhook.
Dashboards & reports render
dashboard-api and reporting-api query the same metrics to render live dashboards and generate scheduled PDF/XLSX reports.
