|
|
|
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
|
|
|
|
|
|
|
|
## Install
|
|
|
|
There are various ways of installing Prometheus.
|
|
|
|
### Precompiled binaries
|
|
|
|
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
|
|
is the recommended way of installing Prometheus.
|
|
See the [Installing](https://prometheus.io/docs/introduction/install/)
|
|
chapter in the documentation for all the details.
|
|
|
|
### 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
|
|
|
|
$ docker run --name prometheus -d -p 127.0.0.1:9090:9090 prom/prometheus
|
|
|
|
Prometheus will now be reachable at http://localhost:9090/.
|
|
|
|
### Building from source
|
|
|
|
To build Prometheus from source code, You need:
|
|
* Go [version 1.14 or greater](https://golang.org/doc/install).
|
|
* NodeJS [version 16 or greater](https://nodejs.org/).
|
|
* npm [version 7 or greater](https://www.npmjs.com/).
|
|
|
|
You can directly use the `go` tool to download and install the `prometheus`
|
|
and `promtool` binaries into your `GOPATH`:
|
|
|
|
$ 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
|
|
new experimental 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 clone the repository yourself and build using `make build`, which will compile in
|
|
the web assets so that Prometheus can be run from anywhere:
|
|
|
|
$ 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 (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 new experimental React UI
|
|
|
|
### 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:
|
|
|
|
$ make promu
|
|
$ promu crossbuild -p linux/amd64
|
|
$ make npm_licenses
|
|
$ make common-docker-amd64
|
|
|
|
*NB* if you are on a Mac, you will need [gnu-tar](https://formulae.brew.sh/formula/gnu-tar).
|
|
|
|
## React UI Development
|
|
|
|
For more information on building, running, and developing on the new React-based UI, see the React app's [README.md](web/ui/README.md).
|
|
|
|
## More information
|
|
|
|
* The source code is periodically indexed, but due to an issue with versioning, the "latest" docs shown on Godoc are outdated. Instead, you can use [the docs for v2.31.1](https://pkg.go.dev/github.com/prometheus/prometheus@v1.8.2-0.20211105201321-411021ada9ab).
|
|
* You will find a CircleCI configuration in [`.circleci/config.yml`](.circleci/config.yml).
|
|
* See the [Community page](https://prometheus.io/community) for how to reach the Prometheus developers and users on various communication channels.
