Readme
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
