You can find a more complete list of both official and community-contributed exporters on Prometheus’ website. nginx-vts-exporter - This provides metrics about an Nginx web server using the Nginx VTS module, including the number of open connections, the number of sent responses (grouped by response codes), and the total size of sent or received requests in bytes.rabbitmq_exporter - This outputs metrics about the RabbitMQ messaging system, including the number of messages published, the number of messages ready to be delivered, and the size of all the messages in the queue.mysqld_exporter - This gathers metrics related to a MySQL server, such as the number of executed queries, average query response time, and cluster replication status.blackbox_exporter - This generates metrics derived from probing protocols like HTTP and HTTPS to determine endpoint availability, response time, and more.node_exporter - This produces metrics about infrastructure, including the current CPU, memory and disk usage, as well as I/O and network statistics, such as the number of bytes read from a disk or a server’s average load.Some of the most popular choices include: ![]() But, you can greatly expand Prometheus by installing exporters, optional programs that generate additional metrics.Įxporters - both the official ones that the Prometheus team maintains as well as the community-contributed ones - provide information about everything from infrastructure, databases, and web servers to messaging systems, APIs, and more. the number of requests it’s received, its memory consumption, etc.). It offers a multi-dimensional data model, a flexible query language, and diverse visualization possibilities through tools like Grafana.īy default, Prometheus only exports metrics about itself (e.g. For a list of trademarks of The Linux Foundation, please see our Trademark Usage page.Prometheus is a powerful, open-source monitoring system that collects metrics from your services and stores them in a time-series database.

Go_gc_duration_seconds metric should display two instances with instance labels localhost:9100 and localhost:9200. To ensure that the Node Exporter is exposing metrics: curl The metrics output should look something like this: # HELP go_gc_duration_seconds A summary of the GC invocation durations. See this section of the Monitoring Linux host metrics with the Node Exporter guide. Install and run a Prometheus instance that is configured to discover the Node Exporter using the targets.json file.Create a targets.json file specifying the host and port information for the Node Exporter.Install and run a Prometheus Node Exporter locally.If you need to use a service discovery system that is not currently supported, your use case may be best served by Prometheus' file-based service discovery mechanism, which enables you to list scrape targets in a JSON file (along with metadata about those targets). Prometheus offers a variety of service discovery options for discovering scrape targets, including Kubernetes, Consul, and many others.
