octsdb

This is a client for the OpenConfig gRPC interface that pushes telemetry to OpenTSDB. Non-numerical data isn't supported by OpenTSDB and is silently dropped.

This tool requires a config file to specify how to map the path of the notificatons coming out of the OpenConfig gRPC interface onto OpenTSDB metric names, and how to extract tags from the path.

Getting Started

To begin, a list of subscriptions is required (excerpt from sampleconfig.json):

	"subscriptions": [
		"/Sysdb/interface/counter/eth/lag",
		"/Sysdb/interface/counter/eth/slice/phy",

		"/Sysdb/environment/temperature/status",
		"/Sysdb/environment/cooling/status",
		"/Sysdb/environment/power/status",

		"/Sysdb/hardware/xcvr/status/all/xcvrStatus"
	],
	...

Note that subscriptions should not end with a trailing / as that will cause the subscription to fail.

Afterwards, the metrics are defined (excerpt from sampleconfig.json):

	"metrics": {
		"tempSensor": {
			"path": "/Sysdb/(environment)/temperature/status/tempSensor/(?P<sensor>.+)/((?:maxT|t)emperature)"
		},
		...
	}

In the metrics path, unnamed matched groups are used to make up the metric name, and named matched groups are used to extract optional tags. Note that unnamed groups are required, otherwise the metric name will be empty and the update will be silently dropped.

For example, using the above metrics path applied to an update for the path /Sysdb/environment/temperature/status/tempSensor/TempSensor1/temperature will lead to the metric name environment.temperature and tags sensor=TempSensor1.

Usage

See the -help output, but here's an example to push all the metrics defined in the sample config file:

octsdb -addr <switch-hostname>:6042 -config sampleconfig.json -text | nc <tsd-hostname> 4242
