A Riemann client and command line tool

Project description

http://img.shields.io/pypi/v/riemann-client.svg http://img.shields.io/pypi/l/riemann-client.svg http://img.shields.io/travis/borntyping/python-riemann-client/master.svg

A Riemann client library and command line tool for Python. It supports UDP and TCP transports, queries, and all metric types. The client library aims to provide a simple, minimal API, and does not require direct interaction with protocol buffers. There is also a queued client that can queue or batch events and then send them in a single message.

This project is no longer maintained. Please contact me by opening an issue on the GitHub project if you’d like to fork this repository and take over the ``riemann-client`` PyPI package.

Usage

As a command line tool:

riemann-client [--host HOST] [--port PORT] send [-s SERVICE] [-S STATE] [-m METRIC] [...]
riemann-client [--host HOST] [--port PORT] query QUERY

The host and port used by the command line tool can also be set with the RIEMANN_HOST and RIEMANN_PORT environment variables. By default, localhost:5555 will be used.

As a library:

import riemann_client.client

with riemann_client.client.Client() as client:
    client.event(service="riemann-client", state="awesome")
    client.query("service = 'riemann-client'")

A more detailed example, using both a non-default transport and a queued client:

from riemann_client.transport import TCPTransport
from riemann_client.client import QueuedClient

with QueuedClient(TCPTransport("localhost", 5555)) as client:
    client.event(service="one", metric_f=0.1)
    client.event(service="two", metric_f=0.2)
    client.flush()

The QueuedClient class modifies the event() method to add events to a queue instead of immediately sending them, and adds the flush() method to send the current event queue as a single message.

Installation

riemann-client requires Python 2.6 or above, and can be installed with pip install riemann-client. It will use Google’s protobuf library when running under Python 2, and GreatFruitOmsk’s protobuf-py3 fork when running under Python 3. Python 3 support is experimental and is likely to use Google’s protobuf once it supports Python 3 fully.

Requirements

Testing (Linux/OSX)

Testing is done with tox:
