Prometheus, a [Cloud Native Computing Foundation](https://cncf.io/) 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**
* An HTTP **pull model** for time series collection
* **Pushing time series** is supported via an intermediary gateway for batch jobs
* Targets are discovered via **service discovery** or **static configuration**
* Multiple modes of **graphing and dashboarding support**
* Support for hierarchical and horizontal **federation**

## Architecture overview
![Architecture overview](documentation/images/architecture.svg)
## Install
There are various ways of installing Prometheus.
2015-05-22 04:31:59 -07:00
### Precompiled binaries
2012-11-24 03:33:34 -08:00
2015-05-22 04:31:59 -07:00
Precompiled binaries for released versions are available in the
[*download* section](https://prometheus.io/download/)
on [prometheus.io](https://prometheus.io). Using the latest production release binary
2016-09-14 20:09:26 -07:00
is the recommended way of installing Prometheus.
See the [Installing](https://prometheus.io/docs/introduction/install/)
chapter in the documentation for all the details.
2015-05-22 04:31:59 -07:00
### Docker images
Docker images are available on [Quay.io](https://quay.io/repository/prometheus/prometheus) or [Docker Hub](https://hub.docker.com/r/prom/prometheus/).
You can launch a Prometheus container for trying it out with
```bash
docker run --name prometheus -d -p 127.0.0.1:9090:9090 prom/prometheus
```
Prometheus will now be reachable at <http://localhost:9090/>.
2015-09-17 09:20:38 -07:00
### Building from source
To build Prometheus from source code, You need:
* Go [version 1.17 or greater](https://golang.org/doc/install).
* NodeJS [version 16 or greater](https://nodejs.org/).
* npm [version 7 or greater](https://www.npmjs.com/).
2015-04-10 04:53:32 -07:00
Start by cloning the repository:
```bash
git clone https://github.com/prometheus/prometheus.git
cd prometheus
```
You can use the `go` tool to build and install the `prometheus`
and `promtool` binaries into your `GOPATH`:
```bash
GO111MODULE=on go install github.com/prometheus/prometheus/cmd/...
prometheus --config.file=your_config.yml
```
*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.](https://github.com/prometheus/prometheus/blob/main/documentation/examples/prometheus.yml)
You can also build using `make build`, which will compile in the web assets so that
Prometheus can be run from anywhere:
```bash
make build
./prometheus --config.file=your_config.yml
```
2015-09-18 00:34:17 -07:00
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
### Service discovery plugins
Prometheus is bundled with many service discovery plugins.
When building Prometheus from source, you can edit the [plugins.yml](./plugins.yml)
file to disable some service discoveries. The file is a yaml-formatted list of go
import path that will be built into the Prometheus binary.
After you have changed the file, you
need to run `make build` again.
If you are using another method to compile Prometheus, `make plugins` will
generate the plugins file accordingly.
If you add out-of-tree plugins, which we do not endorse at the moment,
additional steps might be needed to adjust the `go.mod` and `go.sum` files. As
always, be extra careful when loading third party code.
### Building the Docker image
The `make docker` target is designed for use in our CI system.
You can build a docker image locally with the following commands:
```bash
make promu
promu crossbuild -p linux/amd64
make npm_licenses
make common-docker-amd64
```
## Using Prometheus as a Go Library
### Remote Write
We are publishing our Remote Write protobuf independently at
[buf.build](https://buf.build/prometheus/prometheus/assets).
You can use that as a library:
```shell
go get buf.build/gen/go/prometheus/prometheus/protocolbuffers/go@latest
```
This is experimental.
### Prometheus code base
In order to comply with [go mod](https://go.dev/ref/mod#versions) 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:
```shell
go get github.com/prometheus/prometheus@v0.35.0
```
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](https://semver.org/#spec-item-4).
## React UI Development
For more information on building, running, and developing on the React-based UI, see the React app's [README.md](web/ui/README.md).
## More information
* Godoc documentation is available via [pkg.go.dev](https://pkg.go.dev/github.com/prometheus/prometheus). Due to peculiarities of Go Modules, v2.x.y will be displayed as v0.x.y.
* See the [Community page](https://prometheus.io/community) for how to reach the Prometheus developers and users on various communication channels.
