beorn7 0f191629c6 Next try to deal with backed-up ingestion.
This is now not even trying to throttle in a benign way, but creates a
fully-fledged error. Advantage: It shows up very visible on the status
page. Disadvantage: The server does not really adjusts to a lower
scraping rate. However, if your ingestion backs up, you are in a very
irregulare state, I'd say it _should_ be considered an error and not
dealt with in a more graceful way.

In different news: I'll work on optimizing ingestion so that we will
not as easily run into that situation in the first place.

Prometheus Build Status

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

Architecture overview

Install

There are various ways of installing Prometheus.

Precompiled packages

We plan to provide precompiled binaries for various platforms and even packages for common Linux distributions soon. Once those are offered, it will be the recommended way of installing Prometheus.

Use make

In most cirumstances, the following should work:

$ make build
$ ./prometheus -config.file=documentation/examples/prometheus.conf

The above requires a number of common tools to be installed, namely curl, git, gzip, hg (Mercurial CLI), sed, xxd. Should you need to change any of the protocol buffer definition files (*.proto), you also need the protocol buffer compiler protoc, v2.5.0 or higher, in your $PATH.

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.

The Makefile offers a number of useful targets. Some examples:

  • make test runs tests.
  • make tarball creates a tarball with the binary for distribution.
  • make race_condition_run compiles and runs a binary with the race detector enabled. To pass arguments when running Prometheus this way, set the ARGUMENTS environment 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, but you have to take care of various generated files (usually by running make in the respective sub-directory):

  • Compiling the protocol buffer definitions in config (only if you have changed them).
  • Generating the parser and lexer code in rules (only if you have changed parser.y or lexer.l).
  • The files.go blob in web/blob, which embeds the static web content into the binary.

Furthermore, the build info (see build_info.go) will not be populated if you simply run go build. You have to pass in command line flags as defined in Makefile.INCLUDE (see ${BUILDFLAGS}) to do that.

More information

  • The source code is periodically indexed: Prometheus Core.
  • You will find a Travis CI configuration in .travis.yml.
  • All of the core developers are accessible via the Prometheus Developers Mailinglist and the #prometheus channel on irc.freenode.net.
