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
- federation support coming soon
There are various ways of installing Prometheus.
Precompiled binaries for released versions are available in the releases section 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.
Clone the repository in the usual way with
git clone. (If you
download and unpack the source archives provided by GitHub instead of
git clone, you need to set an environment variable
to make the below work. See
issue #609 for
In most circumstances, the following should work:
$ make build $ ./prometheus -config.file=documentation/examples/prometheus.yml
The above requires a number of common tools to be installed, namely
hg (Mercurial CLI).
Everything else will be downloaded and installed into a staging
environment in the
.build sub-directory. That includes a Go
development environment of the appropriate version.
Makefile offers a number of useful targets. Some examples:
make testruns tests.
make tarballcreates a tarball with the binary for distribution.
make race_condition_runcompiles and runs a binary with the race detector enabled. To pass arguments when running Prometheus this way, set the
ARGUMENTSenvironment variable (e.g.
ARGUMENTS="-config.file=./prometheus.conf" make race_condition_run).
Use your own Go development environment
Using your own Go development environment with the usual tooling is
possible, too. After making changes to the files in
have to run
make in the
web/ directory. This generates the respective
web/blob/files.go file which embedds the static assets in the compiled binary.
Furthermore, the version information (see
version/info.go) will not be
populated if you simply run
go build. You have to pass in command
line flags as defined in
- The source code is periodically indexed: Prometheus Core.
- You will find a Travis CI configuration in
- All of the core developers are accessible via the Prometheus Developers Mailinglist and the
