Riemann Node.js Client (in pure JS)
because you should be monitoring all of those non-blocking buffet plates.
Riemannjs uses ProtoBuf.js, so no native dependencies or complication required.
npm install riemannjs [--save]
first things first, we'll want to establish a new client:
var client =;// If we used TCP for the trasnport we could listen for thisclient;
Just like Riemann ruby client, the client sends small events over UDP, by default. TCP is needed for queries, and large events (where large is determined by many factors like network MTU). There is no acknowledgement of UDP packets, but they are roughly an order of magnitude faster than TCP.
sending events is easy (see list of valid event properties):
If you wanted to send that message over TCP and receive an acknowledgement, you can specify the protocol during connection, explicitly:
var client =client;client;
When you're done monitoring/querying, disconnect if you are using TCP:
metric field is supplied, it's contents are converted to a protobuf
float before transmission rather than
Contributing is easy, just send a pull request, or make an issue / feature request. Please take a look at the project issues, to see how you can help. Here are some helpful tips:
- install the developer dependencies using
npm install --dev
- please add tests. I'm using Mocha as a test runner, you can run the tests using
- please check your syntax with the included jshint configuration using
npm run-script lint. It shouldn't report any errors.
