In the world of cloud-native observability, Prometheus Exporters have emerged as one of the most powerful tools for developers and DevOps engineers to gain deep, real-time insights into system behavior, application performance, and infrastructure health. As we step deeper into 2025, the landscape of Prometheus monitoring has evolved, and exporters have become more versatile, efficient, and tailored for different environments, from microservices and containers to bare metal servers and edge nodes.

This blog takes a comprehensive look at the top Prometheus Exporters in 2025, diving deep into their use cases, benefits, configuration best practices, and how to use them effectively to build a scalable, resilient observability stack. If you're a developer, SRE, platform engineer, or part of an AI/ML Ops team, this guide is crafted with you in mind.

Let’s begin with the fundamentals and then dive into an exhaustive list of top exporters for various technologies and systems.

What Are Prometheus Exporters?
Bridging Metrics Between Systems and Prometheus

Prometheus Exporters are lightweight components that collect data from third-party systems, internal applications, or OS-level metrics, and expose them in the Prometheus exposition format on a /metrics HTTP endpoint. This endpoint is then scraped by Prometheus to collect time-series data, enabling detailed dashboards, alerts, and trend analyses.

Many systems, such as databases, message queues, operating systems, hardware components, and custom applications, don’t natively expose metrics in the Prometheus format. Exporters solve this problem by acting as translators between those systems and Prometheus.

Types of Prometheus Exporters
  1. Official Exporters: Maintained by the Prometheus community. Trusted and production-ready.

  2. Third-party Exporters: Built by the community or companies for specific services.

  3. Custom Exporters: Tailored to your unique applications, often written in Go, Python, or Node.js.

These exporters provide metrics in formats like counters (e.g., requests served), gauges (e.g., current memory usage), histograms (e.g., request duration buckets), and summaries (e.g., quantiles like P99 latency).

Why Developers and DevOps Engineers Rely on Exporters
Low-Footprint, High-Impact Monitoring for All Workloads

Prometheus Exporters are designed to be extremely lightweight, with binaries often under 10MB in size, making them ideal for containerized environments, ephemeral workloads, and systems with minimal overhead allowance.

They are the backbone of monitoring setups where direct instrumentation is either impossible or impractical. Developers use exporters to monitor:

  • System resource usage on nodes

  • Database performance

  • Network I/O statistics

  • Application-level business metrics

  • External service health

  • JVM internals and GC stats

  • Hardware sensors (temperature, power)

By relying on exporters, developers achieve:

  • Modular observability without vendor lock-in

  • Real-time, pull-based monitoring that works seamlessly with Prometheus

  • Unified metric format that integrates directly with Grafana dashboards

  • Auto-discoverable architecture through Kubernetes and service discovery tools

Benefits Over Traditional Monitoring Tools
Agentless, Pull-Based, Cloud-Native Observability

Traditional monitoring systems like Nagios or legacy APMs often require heavy agents that consume system resources, involve complex configurations, and lack flexibility in cloud-native ecosystems. In contrast, Prometheus exporters offer:

  • Agentless architecture: Exporters run independently and expose data over HTTP. No central agent is required.

  • Stateless design: Easy to scale horizontally, ideal for microservices and stateless containers.

  • Decoupled scrapes: Prometheus initiates the connection (pull-based), reducing the complexity of security and firewall rules.

  • Fine-grained control: Exporters can be filtered or scoped to expose only required metrics.

  • Native Grafana integration: Exporters generate metrics that plug directly into pre-built and custom Grafana dashboards.

Developers can rapidly build, test, and evolve their monitoring pipelines by combining the composability of exporters with the expressive power of PromQL, Prometheus’s powerful query language.

Top Prometheus Exporters in 2025

Let’s now look at the most widely adopted and effective Prometheus Exporters for 2025. These exporters are actively maintained, used in production at scale, and offer robust integrations with monitoring stacks.

Node Exporter

The Node Exporter remains the most fundamental and widely deployed exporter in the Prometheus ecosystem. It collects a comprehensive set of system metrics including:

  • CPU usage

  • Memory consumption

  • Disk I/O

  • Network throughput

  • Filesystem statistics

  • System load average

  • Hardware temperature (via lm_sensors)

It’s ideal for:

  • Bare-metal servers

  • Virtual machines

  • Kubernetes worker nodes

  • Cloud VM instances (EC2, GCE, Azure VMs)

Key Developer Benefits:

  • Exposes more than 400 metrics

  • Supports custom collectors (e.g., systemd, TCP stats)

  • Lightweight binary (~9MB)

  • Highly reliable and production-grade

To use Node Exporter, simply download the binary or run the official container image. By default, it runs on port 9100.

Windows Exporter (formerly WMI Exporter)

If you’re operating in a Windows environment, Windows Exporter is your go-to solution. It collects system metrics from Windows hosts using the Windows Management Instrumentation (WMI) interface.

It supports monitoring:

  • CPU, disk, memory, and network

  • Windows Services

  • Active Directory metrics

  • IIS performance

  • Hyper-V and Windows Server roles

Windows Exporter integrates easily with MSI installers and can be managed via services. It also provides granular control over enabled collectors, making it suitable for both minimal and full-stack observability setups on Windows.

PostgreSQL Exporter

Databases are critical, and PostgreSQL Exporter gives developers rich observability into their PostgreSQL instances. It connects to PostgreSQL databases and exposes metrics like:

  • Active connections

  • Query execution times

  • Cache hit ratios

  • Deadlocks

  • Locks

  • Background writer stats

Developer-centric highlights:

  • Secure credentials via environment variables

  • Custom SQL queries to extend metrics

  • Prebuilt Grafana dashboards

  • Supports multiple DB targets via config

Perfect for backend engineers monitoring API latencies tied to DB performance.

MySQL/MariaDB Exporter

Similar to PostgreSQL, this exporter provides deep insight into MySQL and MariaDB performance. Metrics include:

  • Query per second (QPS)

  • InnoDB buffer pool stats

  • Slow queries

  • Connection states

  • Replication health

Deploying it alongside the database service container ensures efficient metric collection with minimal performance overhead.

Redis Exporter

Redis Exporter surfaces valuable performance indicators such as:

  • Keyspace hits/misses

  • Memory fragmentation ratio

  • Connected clients

  • Evicted keys

  • Command stats

Developers integrating Redis for caching or session management benefit greatly from this visibility, especially when diagnosing slowdowns or evictions under load.

Kafka Exporter

Kafka is integral to modern streaming applications. The Kafka Exporter exposes metrics like:

  • Topic partition lags

  • Consumer group offsets

  • Broker health

  • Message throughput

It helps developers track real-time streaming reliability and detect consumer lag or broker bottlenecks before they impact downstream systems.

Blackbox Exporter

Unlike other exporters, Blackbox Exporter is not tied to internal metrics but instead tests the health of external endpoints via:

  • HTTP(s) probes

  • DNS lookups

  • TCP connect checks

  • ICMP pings

This is crucial for synthetic monitoring, where SREs and developers simulate user requests to ensure uptime and availability.

JMX Exporter

For JVM-based applications like Kafka, Cassandra, and Spring Boot, JMX Exporter translates JMX metrics into Prometheus format. It’s often embedded as a Java agent or runs as a sidecar.

It collects:

  • Heap and non-heap memory stats

  • Thread counts

  • GC pause times

  • MBean custom values

A must-have for Java developers and platform teams running JVM services.

eBPF Exporter

One of the most exciting new entrants in 2025, the eBPF Exporter leverages the power of Extended Berkeley Packet Filter (eBPF) for low-overhead kernel-level monitoring. It captures:

  • System calls

  • Network socket stats

  • File I/O latency

  • Process execution traces

It’s ideal for:

  • Performance tuning

  • Security observability

  • Real-time anomaly detection

Since it runs inside the Linux kernel, it provides extremely detailed telemetry with near-zero performance hit.

Custom Exporters: Build Your Own

Sometimes, what you need to monitor is unique. In those cases, writing a custom exporter is both easy and rewarding.

Use cases:

  • Business logic metrics (e.g., transaction success rates)

  • Metrics from closed-source apps

  • Proprietary protocols (e.g., SNMP)

Languages commonly used:

  • Go: Rich Prometheus client library, concurrency support

  • Python: Fast prototyping, readable syntax

  • Node.js/TypeScript: Web app metrics, async data pipelines

All you need is to expose an HTTP endpoint with metrics in the standard Prometheus format.

How to Use Prometheus Exporters Effectively
Choosing the Right Exporter

Use community-curated resources like ExporterHub, PromCat, and Awesome Prometheus Exporters to discover stable and well-documented exporters. Validate that the exporter is actively maintained and supports the features you need.

Deployment Strategies
  • Run exporters as sidecars in Kubernetes for microservices

  • Use systemd services for VM-level monitoring

  • Configure via flags or YAML to enable collectors

  • Isolate exporters in a secure network zone if needed

Scrape Configuration Tips
  • Group jobs by target type (e.g., job_name: "redis" vs. job_name: "node")

  • Use relabeling to control metric label explosion

  • Use honor_labels if exporters have pre-set labels

  • Set scrape_interval based on volatility of metrics (1s–60s range)

Avoiding Common Pitfalls
  • Don’t expose sensitive labels like user IDs

  • Watch out for high cardinality metrics (e.g., per-request ID)

  • Secure the /metrics endpoint behind reverse proxies if needed

  • Use alert rules to ensure exporters themselves are running correctly

Developer Benefits Over Legacy Tools

Developers moving from traditional monitoring systems or black-box APMs gain:

  • Open standards: All metrics conform to a text-based, human-readable format.

  • Low memory and CPU footprint: Exporters typically use <1% CPU even under load.

  • Full control: Developers define what is collected and how often.

  • Portability: Easily integrate with CI/CD, version control, and container orchestration.

  • Cost savings: No licensing or per-host fees. Open-source all the way.
