Prometheus Metrics Server Configuration Guide

Overview

Prometheus is a powerful open-source monitoring and alerting toolkit designed for reliability and scalability. It collects and stores metrics as time series data with dimensional data model.

Container Installation

Docker Run Command

docker run -d \
  --name=prometheus \
  --restart=unless-stopped \
  -p 9090:9090 \
  -v /mnt/user/appdata/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml \
  -v /mnt/user/appdata/prometheus/data:/prometheus \
  -u 99:100 \
  prom/prometheus:latest \
  --config.file=/etc/prometheus/prometheus.yml \
  --storage.tsdb.path=/prometheus \
  --web.console.libraries=/etc/prometheus/console_libraries \
  --web.console.templates=/etc/prometheus/consoles \
  --web.enable-lifecycle \

    • Access: Server (default)
    • HTTP Method: GET

  2. Import Dashboards:

    • Node Exporter: Dashboard ID 1860
    • Docker: Dashboard ID 193
    • Prometheus: Dashboard ID 3662

# alertmanager.yml
global:
  smtp_smarthost: "localhost:587"
  smtp_from: "alerts@yourdomain.com"

route:
  group_by: ["alertname"]
  group_wait: 10s
  group_interval: 10s
  repeat_interval: 1h
  receiver: "web.hook"

receivers:
  - name: "web.hook"
    email_configs:
      - to: "admin@yourdomain.com"
        subject: "Prometheus Alert"
        body: |
          {{ range .Alerts }}
          Alert: {{ .Annotations.summary }}
          Description: {{ .Annotations.description }}
          {{ end }}

With Node Exporter

# Install node-exporter
docker run -d \
  --name=node-exporter \
  --restart=unless-stopped \
  -p 9100:9100 \
  -v "/proc:/host/proc:ro" \
  -v "/sys:/host/sys:ro" \
  -v "/:/rootfs:ro" \
  --pid="host" \
  --network="host" \
  prom/node-exporter:latest \
  --path.procfs="/host/proc" \
  --path.sysfs="/host/sys" \
  --collector.filesystem.mount-points-exclude="^/(sys|proc|dev|host|etc)($$|/)"

Monitoring & Notifications

Health Monitoring

# Check Prometheus health
curl http://localhost:9090/-/healthy

# Check configuration
curl http://localhost:9090/api/v1/status/config

# Check targets
curl http://localhost:9090/api/v1/targets

Query Examples

# CPU usage per core
rate(node_cpu_seconds_total[5m])

# Memory usage percentage
(node_memory_MemTotal_bytes - node_memory_MemAvailable_bytes) / node_memory_MemTotal_bytes * 100

# Disk I/O operations
rate(node_disk_io_time_seconds_total[5m])

# Container CPU usage
rate(container_cpu_usage_seconds_total[5m])

# Network traffic
rate(node_network_receive_bytes_total[5m])

Custom Metrics

# Custom application metrics
- job_name: "custom-app"
  static_configs:
    - targets: ["app:8080"]
  metrics_path: /metrics
  scrape_interval: 30s

Backup Configuration

Database Backup

#!/bin/bash
# Prometheus backup script
DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_DIR="/mnt/user/backups/prometheus"

# Create snapshot
curl -XPOST http://localhost:9090/api/v1/admin/tsdb/snapshot

# Copy data
cp -r /mnt/user/appdata/prometheus/data $BACKUP_DIR/prometheus_$DATE

# Compress backup
tar -czf $BACKUP_DIR/prometheus_$DATE.tar.gz -C $BACKUP_DIR prometheus_$DATE
rm -rf $BACKUP_DIR/prometheus_$DATE

# Retain last 7 days
find $BACKUP_DIR -name "prometheus_*.tar.gz" -mtime +7 -delete

Configuration Backup

#!/bin/bash
# Backup configuration files
cp -r /mnt/user/appdata/prometheus/*.yml /mnt/user/backups/prometheus/config/
cp -r /mnt/user/appdata/prometheus/rules/ /mnt/user/backups/prometheus/config/

Testing Procedures

Connectivity Tests

# Test web interface
curl -I http://localhost:9090

# Test API
curl "http://localhost:9090/api/v1/query?query=up"

# Test configuration reload
curl -X POST http://localhost:9090/-/reload

Query Performance Tests

# Test query response time
prometheus_rule_evaluation_duration_seconds

# Check ingestion rate
rate(prometheus_tsdb_symbol_table_size_bytes[5m])

Alert Testing

# Trigger test alert
curl -X POST http://localhost:9090/api/v1/admin/tsdb/delete_series?match[]=up{job="test"}

Troubleshooting

Common Issues

  1. Configuration Errors:

    # Validate configuration
docker exec prometheus promtool check config /etc/prometheus/prometheus.yml

  2. Target Down:

    # Check target status
curl http://localhost:9090/api/v1/targets | jq

  3. Storage Issues:

    # Check disk usage
docker exec prometheus du -sh /prometheus

Performance Issues

# Check memory usage
docker stats prometheus

# Monitor query performance
curl "http://localhost:9090/api/v1/query?query=prometheus_engine_query_duration_seconds"

Log Analysis

# View logs
docker logs prometheus

# Monitor for errors
docker logs -f prometheus | grep -i error

Maintenance

Regular Updates

# Update Prometheus
docker pull prom/prometheus:latest
docker stop prometheus
docker rm prometheus
# Recreate with docker-compose up -d

Data Retention

# Configure retention policy
--storage.tsdb.retention.time=30d
--storage.tsdb.retention.size=10GB

Cleanup Old Data

# Manual cleanup
curl -X POST \
  "http://localhost:9090/api/v1/admin/tsdb/delete_series?match[]=up{job=\"old-job\"}"

# Clean tombstones
curl -X POST http://localhost:9090/api/v1/admin/tsdb/clean_tombstones

Security Considerations

Authentication

# Basic auth (external proxy)
basic_auth_users:
  admin: $2b$12$hNf2lSsxfm0.i4a.1kVpSOVyBCfIB51VRjgBUyv6kdnyTlgWj81Ay

TLS Configuration

tls_server_config:
  cert_file: /etc/prometheus/prometheus.crt
  key_file: /etc/prometheus/prometheus.key

Network Security

  • Use firewall rules to restrict access
  • Implement reverse proxy with authentication
  • Regular security updates

Advanced Configuration

# Federation setup
- job_name: "federate"
  scrape_interval: 15s
  honor_labels: true
  metrics_path: "/federate"
  params:
    "match[]":
      - "{job=~\"prometheus|node|cadvisor\"}"
  static_configs:
    - targets:
      - "prometheus-child:9090"

Remote Storage

# Remote write configuration
remote_write:
  - url: "http://remote-storage:9201/write"
    queue_config:
      max_samples_per_send: 1000
      max_shards: 200
      capacity: 2500

"{job=~\"prometheus|node|cadvisor\"}" static_configs: - targets: - "prometheus-child:9090" ``` ### Remote Storage ```yaml # Remote write configuration remote_write: - url: "http://remote-storage:9201/write" queue_config: max_samples_per_send: 1000 max_shards: 200 capacity: 2500 ``` ### Service Discovery ```yaml # Docker service discovery - job_name: "docker" docker_sd_configs: - host: unix:///var/run/docker.sock relabel_configs: - source_labels: [__meta_docker_container_name] target_label: container ``` This guide provides comprehensive coverage of Prometheus monitoring server setup and configuration.
