# Prometheus [](https://travis-ci.org/prometheus/prometheus) [](https://circleci.com/gh/prometheus/prometheus/tree/master)
|
|
|
|
Prometheus 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 if some condition is observed
|
|
to be true.
|
|
|
|
Prometheus' main distinguishing features as compared to other monitoring systems are:
|
|
|
|
- a **multi-dimensional** data model (timeseries defined by metric name and set of key/value dimensions)
|
|
- a **flexible query language** to leverage this dimensionality
|
|
- no dependency on distributed storage; **single server nodes are autonomous**
|
|
- timeseries collection happens via a **pull model** over HTTP
|
|
- **pushing timeseries** is supported via an intermediary gateway
|
|
- targets are discovered via **service discovery** or **static configuration**
|
|
- multiple modes of **graphing and dashboarding support**
|
|
- support for hierarchical and horizontal **federation**
|
|
|
|
## Architecture overview
|
|
|
|
|
|
|
|
## Install
|
|
|
|
There are various ways of installing Prometheus.
|
|
|
|
### Precompiled binaries
|
|
|
|
Precompiled binaries for released versions are available in the
|
|
[*releases* section](https://github.com/prometheus/prometheus/releases)
|
|
of the GitHub repository. Using the latest production release binary
|
|
is the recommended way of installing Prometheus.
|
|
|
|
Debian and RPM packages are being worked on.
|
|
|
|
### Building from source
|
|
|
|
To build Prometheus from the source code yourself you need to have a working
|
|
Go environment with [version 1.5 or greater installed](http://golang.org/doc/install).
|
|
|
|
You can directly use the `go` tool to download and install the `prometheus`
|
|
and `promtool` binaries into your `GOPATH`. We use Go 1.5's experimental
|
|
vendoring feature, so you will also need to set the `GO15VENDOREXPERIMENT=1`
|
|
environment variable in this case:
|
|
|
|
$ GO15VENDOREXPERIMENT=1 go get github.com/prometheus/prometheus/cmd/...
|
|
$ prometheus -config.file=your_config.yml
|
|
|
|
You can also clone the repository yourself and build using `make`:
|
|
|
|
$ mkdir -p $GOPATH/src/github.com/prometheus
|
|
$ cd $GOPATH/src/github.com/prometheus
|
|
$ git clone https://github.com/prometheus/prometheus.git
|
|
$ cd prometheus
|
|
$ make build
|
|
$ ./prometheus -config.file=your_config.yml
|
|
|
|
The Makefile provides several targets:
|
|
|
|
* *build*: build the `prometheus` and `promtool` binaries
|
|
* *test*: run the tests
|
|
* *format*: format the source code
|
|
* *vet*: check the source code for common errors
|
|
* *assets*: rebuild the static assets
|
|
* *docker*: build a docker container for the current `HEAD`
|
|
|
|
## More information
|
|
|
|
* The source code is periodically indexed: [Prometheus Core](http://godoc.org/github.com/prometheus/prometheus).
|
|
* You will find a Travis CI configuration in `.travis.yml`.
|
|
* All of the core developers are accessible via the [Prometheus Developers Mailinglist](https://groups.google.com/forum/?fromgroups#!forum/prometheus-developers) and the `#prometheus` channel on `irc.freenode.net`.
