$ cd /path/to/statsd $ npm install statsd-librato-backend
You will need to add the following to your StatsD config file.

statsd-librato-backend backend to the list of StatsD
backends in the StatsD configuration file:
Start/restart the statsd daemon and your StatsD metrics should now be pushed to your Librato account.
The Librato backend also supports the following optional configuration
options under the top-level
snapTime: Measurement timestamps are snapped to this interval
(specified in seconds). This makes it easier to align
measurements sent from multiple statsd instances on a
single graph. Default is to use the flush interval time.
countersAsGauges: A boolean that controls whether StatsD counters
are sent to Librato as gauge values (default) or
as counters. When set to true (default), the
backend will send the aggregate value of all
increment/decrement operations during a flush
period as a gauge measurement to Librato.
When set to false, the backend will track the running value of all counters and submit the current absolute value to Librato as a counter. This will require some additional memory overhead and processing time to track the running value of all counters.
skipInternalMetrics: Boolean of whether to skip publishing of
internal statsd metrics. This includes all
metrics beginning with 'statsd.' and the
metric numStats. Defaults to true, implying
they are not sent.
retryDelaySecs: How long to wait before retrying a failed
request, in seconds.
postTimeoutSecs: Max time for POST requests to Librato, in
that match any of the regular expressions will be sent to Librato.
Defaults to an empty array.
includeMetrics: /^my\.included\.metrics/ /^my.specifically.included.metric$/
any of the regular expressions will NOT be sent to Librato. If includedMetrics
is specified, then patterns will be matched against the resulting
list of included metrics.
Defaults to an empty array.
Metrics which are sent to StatsDThis will exclude metrics sent to StatsD so that metrics which match the specified regex value
excludeMetrics: /^my\.excluded\.metrics/ /^my.specifically.excluded.metric$/
globalPrefix: A string to prepend to all measurement names sent to Librato. If set, a dot will automatically be added as separator between prefix and measurement name.
By default StatsD will push a zero value for any counter that does not receive an update during a flush interval. Similarly, it will continue to push the last seen value of any gauge that hasn't received an update during the flush interval. This is required for some backend systems that can not handle sporadic metric reports and therefore require a fixed frequency of incoming metrics. However, it requires StatsD to track all known gauges and counters and means that published payloads are inflated with zero-fill data.
Librato can handle sporadic metric publishing at non-fixed frequencies. Any "zero filling" of graphs is handled at display time on the frontend. Therefore, when using the Librato backend it is beneficial for bandwidth and measurement-pricing costs to reduce the amount of data sent to Librato. In the StatsD configuration file it is recommended that you enable the following top-level configuration directive to reduce the amount of zero-fill data StatsD sends:
You can configure your metric in Librato to display the gaps between sporadic reports in a variety of ways. Visit the knowledge base article to see how to change the display attributes.
You can push metrics to Graphite and Librato simultaneously as
you evaluate Librato. Just include both backends in the
backends: "./backends/graphite" "statsd-librato-backend"...
See the statsd manpage for more information.
If you want to use statsd-librato-backend througth a proxy you should install https-proxy-agent module:
$npm install https-proxy-agent
After that you should add the proxy config to the StatsD config file in the librato configuration section:
"librato" :"proxy" :"uri" : ""
That configuration will proxy requests via a proxy listening on localhost on port 8080. You can also use an https proxy by setting the protocol to https in the URI.
Starting in version 2.x.x and higher, this functionality is enabled by default. If you are interested in using this feature but your Librato account is not enabled for tags, please send us an email at firstname.lastname@example.org and request access. Otherwise, see this branch for the legacy version 0.1.7.
Our backend plugin offers basic tagging support for your metrics you submit to Librato. You can specify what tags you want to submit to Librato using the tags config in the librato configuration section of the StatsD config file:
"librato" :"tags": "os" : "ubuntu" "host" : "production-web-server-1" ...
Once your config has been updated, all metrics submitted to Librato will include your defined tags.
We also support tags at the per-stat level should you need more detailed tagging. We provide a naming syntax for your stats so you can submit tags for each stat. That syntax is as follows:
Starting with a
#, you would pass in a comma-separated list of tags and we will parse out the tags and values. Given the above example, a stat matching
the above syntax will be submitted as metric to Librato with a name of
metric.name, a value of
value and with the tags
tag1=value and `tag2=value. You are welcome to use any statsd client of your choosing.
Please note that in order to use tags, the statsd config option
keyNameSanitize must be set to
false to properly parse tags out of your stat name.
You may use
bin/statsd-librato to easily bootstrap the daemon inside
Invoking this via
ENTRYPOINT will create a simple
configuration and run the statsd daemon with this backend enabled,
The following environment variables are available to customize:
