nsolid-graphite

2.2.0 • Public • Published

nsolid-graphite - a daemon that sends N|Solid metrics to graphite

This package provides a daemon which will monitor N|Solid Storage and send the metrics from the N|Solid runtimes to graphite via the Graphite protocol over UDP.

installation

npm install nsolid-graphite

usage

nsolid-graphite [options] [graphite-address [storage-address]]

where:

graphite-address - the {address} of the graphite UDP server
                 default: localhost:2003

storage-address  - the {address} of the N|Solid storage server's API port
                 default: localhost:4000

See {address} below for the expected format of these addresses.

options are:

-h --help            - print some help text
-v --version         - print the program version
--app <app name>     - the N|Solid application name to monitor
                       default: monitor all applications
--prefix <value>     - prefix graphite metric names with the specified value
                       default: 'nsolid'

Options are parsed with the npm rc module, and so options can be set in environment variables or files, as supported by rc. For example, you can specify options in a file named .nsolid-statsdrc.

The {address} parameter of the graphite-address and storage-address parameters should be in one of the following formats:

:
port
host
host:port

If port is not specified, the default is 2003 for graphite-address, and 4000 for storage-address. If host is not specified, the default is localhost. The host may be a hostname or IPv4 address.

examples

nsolid-graphite example.com

Poll metrics from the N|Solid storage at localhost:4000 and send them to the graphite server at example.com:2003.

docker

NodeSource provides a Docker image to easily get add nsolid-graphite to an environment already using containers.

docker pull nodesource/nsolid-graphite

Running the nsolid-graphite image

docker run -d --name="nsolid-graphite" nsolid-graphite graphite:2003 storage:4000 

Poll metrics every second from the N|Solid storage at storage:4000 and send them to the graphite server at graphite:2003.

nsolid-graphite also supports using environment variables for providing the N|Solid Storage and graphite endpoints

docker run -d --name="nsolid-graphite" -e NSOLID_ADDRESS=storage:4000 -e GRAPHITE_ADDRESS=graphite:2003 nsolid-graphite

graphite metric names

N|Solid gathers an extensive list of metrics from the N|Solid Runtime to provide the greatest insight into your Node.js applications.

The full list of metrics with descriptions can be found at N|Solid Metrics.

The default format of the metric names is:

{prefix}.{app}.{hostname}.{statName}

The {prefix} value can be specified via command-line option, and defaults to nsolid. The {app} value is the name of the N|Solid application.

string value normalization

String values which are provided by N|Solid will be normalized in the following fashion before being used in a graphite metric

  • characters which are not alpha-numeric or "-" or "_" will be converted to "-"
  • strings that are greater than 200 characters will be truncated to 200 characters

The values which are affected are:

  • N|Solid application name
  • N|Solid hostname
