Get Started with Prometheus
Learn to monitor Kubernetes clusters and applications with Prometheus, Grafana, and Alertmanager. Set up comprehensive observability and alerting systems from scratch.
Quick Start Guide
Prometheus Features
Metrics Collection
Collect metrics from applications, services, and infrastructure.
PromQL Querying
Powerful query language for analyzing time-series data.
Alerting
Configure alerts based on metric thresholds and conditions.
Visualization
Create rich dashboards and visualizations with Grafana.
Monitoring Stack Components
Prometheus Server
Time-series database and metrics collection engine.
Key Features:
Grafana
Visualization and dashboard platform for metrics.
Key Features:
Alertmanager
Alert routing and notification management system.
Key Features:
Exporters
Bridge between applications and Prometheus metrics.
Key Features:
Prometheus Metrics Types
Counter
A cumulative metric that represents a single monotonically increasing counter.
Example:
http_requests_total
Use Cases:
Request counts, error counts
Gauge
A metric that represents a single numerical value that can arbitrarily go up and down.
Example:
memory_usage_bytes
Use Cases:
Current memory usage, active connections
Histogram
A metric that represents a distribution of values in buckets.
Example:
http_request_duration_seconds
Use Cases:
Request latency, response sizes
Summary
Similar to histogram but with configurable quantiles.
Example:
http_request_duration_seconds_summary
Use Cases:
Latency percentiles, quantiles
