The Blackbox exporter is a tool that allows engineers to perform one simple thing that every system administrator does every day, check the availability of HTTP/S, DNS, TCP, and ICMP endpoints.īasically, the Prometheus Blackbox exporter can be seen as a free simple alternative to PingDOM, Freshping, or to monitor internal endpoints not exposed on the Internet. Blackbox is one of the official exporters maintained by the Prometheus organization. Today, many exporters exist and are maintained as part of the official Prometheus GitHub organization, others are maintained by external contributors. The Prometheus stack is composed of multiple pieces: the Prometheus server that stores and serves the data, the Alert Manager that manages the alerts, and tons of Prometheus exporters that perform the metric collection.Īn exporter is software dedicated to one thing, fetching statistics from another application and exposing them to a specific endpoint (generally, a port and a path) to allow the collection of those metrics by a remote Prometheus server. It has a powerful data model and a query language to analyze how applications and infrastructure perform. Prometheus does one thing, and it does it well. ![]() What Is Prometheus Blackbox?Īs everyone knows, Prometheus is an open-source, metrics-based monitoring system. As the project has seen a growing commercial ecosystem of implementers and adopters, a need has emerged to address specific aspects already implemented in older monitoring tools like Nagios. In 2016, it was the second project to join CNCF and, in 2018, the second project to be graduated after Kubernetes. ![]() Today, Prometheus is used widely in production by organizations. ![]()
