# 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
|
|
If you read below in the _Getting Started_ section, the build infrastructure
|
|
will take care of the following things for you in most cases:
|
|
|
|
1. Go 1.1.
|
|
2. LevelDB: [https://code.google.com/p/leveldb/](https://code.google.com/p/leveldb/).
|
|
3. Protocol Buffers Compiler: [http://code.google.com/p/protobuf/](http://code.google.com/p/protobuf/).
|
|
4. goprotobuf: the code generator and runtime library: [http://code.google.com/p/goprotobuf/](http://code.google.com/p/goprotobuf/).
|
|
5. Levigo, a Go-wrapper around LevelDB's C library: [https://github.com/jmhodges/levigo](https://github.com/jmhodges/levigo).
|
|
6. GoRest, a RESTful style web-services framework: [http://code.google.com/p/gorest/](http://code.google.com/p/gorest/).
|
|
7. Prometheus Client, Prometheus in Prometheus [https://github.com/prometheus/client_golang](https://github.com/prometheus/client_golang).
|
|
8. Snappy, a compression library for LevelDB and Levigo [http://code.google.com/p/snappy/](http://code.google.com/p/snappy/).
|
|
|
|
## Getting Started
|
|
|
|
For basic help how to get started:
|
|
|
|
* The source code is periodically indexed: [Prometheus Core](http://godoc.org/github.com/prometheus/prometheus).
|
|
* For UNIX-like environment users users, please consult the Travis CI configuration in _.travis.yml_ and _Makefile_.
|
|
* All of the core developers are accessible via the [Prometheus Developers Mailinglist](https://groups.google.com/forum/?fromgroups#!forum/prometheus-developers).
|
|
|
|
### General
|
|
|
|
For first time users, simply run the following:
|
|
|
|
$ make
|
|
|
|
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.
|
|
|
|
Executing the following target will start up Prometheus for lazy users:
|
|
|
|
$ ARGUMENTS="-foo -bar -baz" 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.
|
|
|
|
### 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](http://tip.golang.org/doc/articles/race_detector.html)
|
|
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
|
|
|

## Contributing
|
|
|
|
1. To start, reach out via our mailing list (mentioned above) and ask us what
|
|
the current priorities are. We can find a good isolated starter project for
|
|
you.
|
|
|
|
2. Keeping code hygiene is important. We thusly have a practical preference
|
|
for the following:
|
|
|
|
1. Run ``make format`` to ensure the correctness of the Go code's layout.
|
|
|
|
2. Run ``make advice`` to find facial errors with a static analyzer.
|
|
|
|
3. Try to capture your changes in some form of a test. Go makes it easy to
|
|
write [Table Driven Tests](https://code.google.com/p/go-wiki/wiki/TableDrivenTests).
|
|
There is no mandate to use this said scaffolding mechanism, but it _can_
|
|
make your life easier in the right circumstances.
