Prometheus, a [Cloud Native Computing Foundation](https://cncf.io/) project, is a systems and service monitoring system. It collects metrics
15

18
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's main distinguishing features as compared to other monitoring systems are:

27

- 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**
28
- support for hierarchical and horizontal **federation**

is the recommended way of installing Prometheus.
See the [Installing](https://prometheus.io/docs/introduction/install/)
45
chapter in the documentation for all the details.

Debian packages [are available](https://packages.debian.org/sid/net/prometheus).

### Docker images
50

51
Docker images are available on [Quay.io](https://quay.io/repository/prometheus/prometheus) or [Docker Hub](https://hub.docker.com/r/prom/prometheus/).
52

53
54
You can launch a Prometheus container for trying it out with

55
    $ docker run --name prometheus -d -p 127.0.0.1:9090:9090 prom/prometheus
56
57
58

Prometheus will now be reachable at http://localhost:9090/.

59
### Building from source
60

61
To build Prometheus from the source code yourself you need to have a working
62
Go environment with [version 1.13 or greater installed](https://golang.org/doc/install).

64
You can directly use the `go` tool to download and install the `prometheus`
65
and `promtool` binaries into your `GOPATH`:
66

67
    $ go get github.com/prometheus/prometheus/cmd/...
68
    $ prometheus --config.file=your_config.yml
69

70
You can also clone the repository yourself and build using `make`:
71

72
73
74
75
    $ mkdir -p $GOPATH/src/github.com/prometheus
    $ cd $GOPATH/src/github.com/prometheus
    $ git clone https://github.com/prometheus/prometheus.git
    $ cd prometheus
76
    $ make build
77
    $ ./prometheus --config.file=your_config.yml
78

79
The Makefile provides several targets:
80

81
82
  * *build*: build the `prometheus` and `promtool` binaries
  * *test*: run the tests
83
  * *test-short*: run the short tests
84
85
86
87
  * *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`
