Bjoern Rabenstein 006b5517e2 Simplify makefiles.
This removes the dependancy on C leveldb and snappy.
It also takes care of fewer dependencies as they would
anyway not work on any non-Debian, non-Brew system.

Prometheus

Bedecke deinen Himmel, Zeus! A new kid is in town.

Prometheus is a generic time series collection and computation server that is useful in the following fields:

  • Industrial Experimentation / Real-Time Behavioral Validation / Software Release Qualification
  • Econometric and Natural Sciences
  • Operational Concerns and Monitoring

The system is designed to collect telemetry from named targets on given intervals, evaluate rule expressions, display the results, and trigger an action if some condition is observed to be true.

Prerequisites

In your PATH, you must have the following binaries available:

  • curl
  • xxd
  • sed
  • gzip

If you change any of the *.proto files, you need to install [protoc, the protobuf compiler](http://code.google.com/p/protobuf/](http://code.google.com/p/protobuf/), v2.5.0 or higher.

Getting Started

For basic help how to get started:

  • The source code is periodically indexed: Prometheus Core.
  • For UNIX-like environment users, please consult the Travis CI configuration in .travis.yml and Makefile.
  • All of the core developers are accessible via the Prometheus Developers Mailinglist.

General

For first time users, simply run the following:

$ make
$ ARGUMENTS="-configFile=documentation/examples/prometheus.conf" make run

${ARGUMENTS} is passed verbatim into the makefile and thusly Prometheus as $(ARGUMENTS). This is useful for quick one-off invocations and smoke testing.

If you run into problems, try the following:

$ SILENCE_THIRD_PARTY_BUILDS=false make

Upon having a satisfactory build, it's possible to create an artifact for end-user distribution:

$ make package
$ find build/package

build/package will be sufficient for whatever archiving mechanism you choose. The important thing to note is that Go presently does not staticly link against C dependency libraries, so including the lib directory is paramount. Providing LD_LIBRARY_PATH or DYLD_LIBRARY_PATH in a scaffolding shell script is advised.

Problems

If at any point you run into an error with the make build system in terms of its not properly scaffolding things on a given environment, please file a bug or open a pull request with your changes if you can fix it yourself.

Please note that we're explicitly shooting for stable runtime environments and not the latest-whiz bang releases; thusly, we ask you to provide ample architecture and release identification remarks for us.

Testing

$ make test

Packaging

$ make package

Race Detector

Go 1.1 includes a race detector which can be enabled at build time. Here's how to use it with Prometheus (assumes that you've already run a successful build).

To run the tests with race detection:

$ GORACE="log_path=/tmp/foo" go test -race ./...

To run the server with race detection:

$ go build -race .
$ GORACE="log_path=/tmp/foo" ./prometheus
