Prometheus & Grafana Setup for Real-Time Linux Server Monitoring

We set up Prometheus and Grafana so your Real-Time Linux Server fleet shows live metrics, alerts, and trends before downtime hits production.

What You'll Get

• Prometheus install & scrape config - Node and app exporters with sane intervals
• Grafana dashboards - CPU, memory, disk, network, and service panels
• Alert rules - Thresholds for load, disk full, and target down
• Retention & storage tuning - Avoid silent metric loss
• Handoff notes - How to read panels and silence noise

Serving Real-Time Linux Server & surrounds

Remote delivery for operators running always-on Linux hosts—CBD SaaS boxes, industrial warehouse backends, and freight-season peaks where lag kills SLAs. We focus on Real-Time Linux Server workloads; metro and regional clients get the same hardened stack.

• Apartment-dense retail POS backends needing overnight disk alerts
• Warehouse precinct APIs under seasonal load spikes
• Fully remote setup—SSH access only; no on-site travel required

How We Work

1. Step 1: Reach Out - Share OS, host count, and pain points
2. Step 2: Tailored Plan - Fixed quote for stack scope
3. Step 3: We Deliver - Remote install, scrape jobs, dashboards, alerts
4. Step 4: Confirm & Follow-up - Verify panels and optional retention review

Common Issues & How to Fix Them

Prometheus target shows DOWN / scrape timeouts

Firewall, wrong port, or exporter not bound—dashboards go blank while hosts still run.

1. Step 1: curl -s localhost:9100/metrics | head on the host
2. Step 2: Open scrape port; fix job targets in prometheus.yml; reload
3. Step 3: Confirm UP in /targets and fresh samples in Grafana

OOM or slow queries from high cardinality

Unbounded labels (user IDs, UUIDs) explode series and RAM.

1. Step 1: Check prometheus_tsdb_head_series and top metrics
2. Step 2: Drop high-card labels; shorten retention; raise scrape interval
3. Step 3: Restart and watch series count and query latency fall

Grafana panels empty despite healthy Prometheus

Wrong datasource UID, time range, or metric name drift after exporter upgrade.

1. Step 1: Explore → Metrics browser; test a simple rate() query
2. Step 2: Fix datasource URL/UID; align panel PromQL to real names
3. Step 3: Set Last 15m and confirm non-null time series
