Monitoring & Observability
Complete Observability
Metrics, Logs & Alerting
From low-level host telemetry to service-level dashboards, I set up the stack so your team can see what is happening, investigate why it happened, and act before users report it.
What I deliver:
- VictoriaMetrics — high-cardinality-friendly metrics storage and queries
- VictoriaLogs — centralized log storage and fast search across hosts
- Grafana — dashboards for service health, capacity, and the KPIs you actually use
- Uptime Kuma — external checks for websites, APIs, certificates, and critical endpoints
- Alerting — actionable notifications through your chosen channel, with runbooks attached
You get:
- End-to-end visibility from the edge to application dependencies
- Historical context for capacity planning and incident investigation
- Alerts tied to user-visible symptoms rather than routine resource noise
- Retention and access designed around your operational and compliance needs
From Metrics to Evidence
A dashboard is useful only when it answers a question. I start with the failures you need to detect, work backwards to the signals that reveal them, and then verify each signal with a real probe.
That means an endpoint monitor must receive a request, a log rule must match the resulting line, and an alert must reach the destination. Configuration that merely exists is not evidence that the path works.
What the Stack Looks Like
| Component | Purpose |
|---|---|
| VictoriaMetrics | Metrics storage and query engine |
| VMAgent | Host and service metric collection |
| VictoriaLogs | Centralized log ingestion and search |
| vlagent | Log shipping from every host |
| Grafana | Dashboards, annotations, and alert rules |
| Uptime Kuma | Black-box monitoring of public and internal services |
| autokuma | Public status page sourced from monitor state |
Operational Boundaries
Observability does not make a system more available by itself. It shortens the interval between failure and recognition, and gives recovery a record to work from. Pair monitoring with the deployment, rollback, and backup practices on the DevOps & Automation service page.
Need an assessment of what you are already running? The Infrastructure Audit approach tests whether the settings produce the telemetry they claim to.
