node client for StatsD server with datadog extensions
Most of the code (including parts of this readme) is copied directly from the excellent https://github.com/sivy/node-statsd (v0.0.7), and the datadog parts wrote in by looking at https://github.com/joybro/node-dogstatsd, but with an added twist in the API.
IMPORTANT: This is not a drop-in replacement for node-statsd or node-dogstatsd, the API has changed.
This client will let you fire stats at your StatsD server from a node.js application.
node-statsd Runs and is tested on Node 0.6+ on all *nix platforms and 0.8+ on all platforms including Windows. (So this should work too.)
All initialization parameters are optional.
Parameters (specified as an options hash):
host: The host to send stats to
port: The port to send stats to
prefix: What to prefix each stat name with
suffix: What to suffix each stat name with
globalize: Expose this StatsD instance globally?
dnsCache: Cache the initial dns lookup to host
mock: Create a mock StatsD instance, sending no stats to the server?
All StatsD/DataDog methods have the same API:
name: Stat name
value: Stat value
required except in increment/decrement where it defaults to 1/-1 respectively
which returns a Stat Object which can sent by calling .send() on them. Additional options to the stat maybe chained by calling stat.sampleRate(value).tags(['x:1']) before sending.
If an array is specified as the
name parameter each item in that array will be sent along with the specified value.
var StatsD = StatsDclient = ;// Timing: sends a timing command with the specified millisecondsclient;// Increment: Increments a stat by a value (default is 1)client;// Decrement: Decrements a stat by a value (default is -1)client;// Gauge: Gauge a stat by a specified amountclient;// Histogram: Datadog's histogramclient;// Set: Counts unique occurrences of a stat (alias of unique)client;client;// Incrementing multiple itemsclient;// Sampling, this will sample 25% of the time the StatsD Daemon will compensate for samplingclient;// Datadog's Tagsclienttags'host:xyz';// Using the callbackclient;
In the event that there is a socket error,
node-statsd will allow this error to bubble up. If you would like to catch the errors, just attach a listener to the socket property on the instance.
If you want to catch errors in sending a message then use the callback provided.
