Flexibility, implementing a new tool is never easy, so having easy integration with existing platforms like Kubernetes is a big advantage.īlackbox is an official exporter managed by the Prometheus organization on GitHub.

Portability, another big aspect of a monitoring stack, nobody can predict the evolution of the infrastructure, ensuring that a tool can be deployed on-premise, in the Cloud, in different ways is nice to have.

Scalability, depending on the number of checks, Blackbox might need to be scaled.

High availability, the most important aspect, ensuring the availability of the monitoring tools is the top priority of each administrator.

As the purpose of this exporter is to monitor critical aspects of the infrastructure, it is highly recommended to deploy it on a container orchestration platform to take advantage of this type of platform: Like any Prometheus exporter, Blackbox can be deployed on any operating system or as a container. Blackbox implicitly validates the status of external services like DNS resolution, network connectivity, Certificate Authority, etc whereas application instrumentation focuses on performance metrics.ĭeployed on a Kubernetes cluster, this exporter can provide a free, highly available monitoring process to get a big overview of remote endpoints.

It’s not just the client-facing endpoints that need to be monitored, internal endpoints are also required to be monitored to ensure continuity of service for our first customers, our colleagues.īlackbox differs from application instrumentation (client libraries added to the code of an application to expose metrics). These metrics are an important piece of the infrastructure that needs to be monitored to ensure continuity of service and compliance with some security certification. Header validation, can I find a required parameter in the HTTP header? Does the header conform to the security compliance?.Basic authentication, can I run a simple web scenario like authentication on a remote endpoint?.

TLS version, what is the TLS version of the remote endpoint?.SSL certificates information, Is the remote endpoint secure? Is it a valid certificate? What is the certificate expiration date?.DNS lookups latencies, how long does it take to resolve a DNS record?.HTTP latencies, how long does it take to get access to the remote endpoints?.The main purpose of the Prometheus Blackbox exporter is to measure the response time of remote internal and external endpoints (HTTP/S, DNS, TCP, and ICMP) but it provides more than that.

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.
