Sep 11, 2024 · One of the highlights in Prometheus 3.0 is its brand new UI that is enabled by default: The UI has been completely rewritten with less clutter, a more modern look and feel, new features like a PromLens -style tree view, and will make future maintenance easier by using a more modern technical stack.
An open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach.

Prometheus, a Cloud Native Computing Foundation project, is a systems and service monitoring system. It collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts when specified conditions are observed.
The features that distinguish Prometheus from other metrics and monitoring systems are:
•A multi-dimensional data model (time series defined by metric name and set of key/value dimensions)
•PromQL, a powerful and flexible query language to leverage this dimensionality
•No dependency on distributed storage; single server nodes are autonomous
Precompiled binaries
Precompiled binaries for released versions are available in the download section on prometheus.io. Using the latest production release binary is the recommended way of installing Prometheus. See the Installing chapter in the documentation for all the details.
Docker images
Docker images are available on Quay.io or Docker Hub. You can launch a Prometheus container for trying it out with Prometheus will now be reachable at http://localhost:9090/.
Building from source
To build Prometheus from source code, You need: •Go version 1.17 or greater. •NodeJS version 16 or greater. •npm version 7 or greater. Start by cloning the repository: You can use the go tool to build and install the prometheus and promtool binaries into your GOPATH: However, when using go install to build Prometheus, Prometheus will expect to be able to read its web assets from local filesystem directories under web/ui/static and web/ui/templates. In order for these assets to be found, you will have to run Prometheus from the root of the cloned repository. Note also that these directories do not include the React UI unless it has been built explicitly using make assets or make build. An example of the above configuration file can be found here. You can also build using make build, which will compile in the web assets so that Prometheus can be run from anywhere: The Makefile provides several targets: •build: build the prometheus and promtool binaries (includes building and compiling in web assets) •test: run the tests •test-short: run the short tests •format: format the source code •vet: check the source code for common errors •assets: build the React UI
Remote Write
We are publishing our Remote Write protobuf independently at buf.build. You can use that as a library: This is experimental.
Prometheus code base
In order to comply with go mod rules, Prometheus release number do not exactly match Go module releases. For the Prometheus v2.y.z releases, we are publishing equivalent v0.y.z tags. Therefore, a user that would want to use Prometheus v2.35.0 as a library could do: This solution makes it clear that we might break our internal Go APIs between minor user-facing releases, as breaking changes are allowed in major version zero.
For more information on building, running, and developing on the React-based UI, see the React app's README.md.
•Godoc documentation is available via pkg.go.dev. Due to peculiarities of Go Modules, v2.x.y will be displayed as v0.x.y.
•See the Community page for how to reach the Prometheus developers and users on various communication channels.
The next release candidate of Prometheus v2.55 has a few bug-fixes to queries, plus the experimental info function which we are including to facilitate feedback. The auto-reload-config feature was removed from v2.55 as it needed more fixes; it is available in v3.0 beta 1. This is yet another beta ...

Jul 31, 2024 · Prometheus core is indeed free and open-source. It's released under the Apache 2.0 license, which allows users to use, modify, and distribute the software without charge. This means you can download, install, and use Prometheus without paying any licensing fees. However, "free" doesn't always mean "without cost."
