Tool / Exporter	What it Does	How it Helps
Prometheus	Core monitoring system & time-series database	Collects and stores metrics from all your services, servers, and apps; acts as the central brain for monitoring
Alertmanager	Handles alerts from Prometheus	Sends notifications (email, Slack, PagerDuty) when issues occur, so teams can respond quickly and avoid downtime
Blackbox Exporter	Tests endpoints (HTTP, DNS, TCP, ICMP)	Monitors external services, APIs, and websites; ensures uptime and performance of services you depend on
Consul Exporter	Exposes metrics from HashiCorp Consul	Monitors service discovery, health of microservices, and Consul itself; helps avoid misconfigured or down services
Graphite Exporter	Bridges Prometheus with Graphite metrics	Allows companies with legacy Graphite dashboards to integrate data into Prometheus, avoiding data silos
Memcached Exporter	Monitors Memcached instances	Tracks cache performance, hit/miss ratios, and memory usage; prevents slow responses due to caching issues
mysqld_exporter	Monitors MySQL/MariaDB databases	Tracks database queries, connections, and performance; helps optimize DB performance and detect issues early
Node Exporter	Monitors OS-level metrics (CPU, memory, disk)	Gives full visibility into servers and infrastructure; helps prevent server bottlenecks and crashes
PromLens	Prometheus query helper / debugging tool	Helps DevOps and developers write correct PromQL queries, speeding up troubleshooting and reporting
Pushgateway	Allows short-lived jobs to push metrics	Useful for batch jobs, cron tasks, or CI pipelines that don’t run continuously; ensures all metrics are collected
StatsD Exporter	Converts StatsD metrics to Prometheus format	Integrates legacy StatsD-based applications into Prometheus monitoring; keeps all metrics in one place
