Tracing Measurement Flow

We use the voltage meter analogy, testing for voltage along a circuit, to similiarly trace the flow of a measurement from the meter plugin to the TrueSight Pulse cloud.

NOTE: Measurement flow tracing techniques described here are currently only applicable to UNIX/Linux environments where system tools exist that provide the ability to trace the measurement flow.

Measurement Pathway

The pathway for measurements sent to TrueSight Pulse are:

  1. Meter Plugin Sends A Measurement - Meter plugin sends measurements to standard output via protocol. Runtime observation of the meter plugin sending measurements is described in .

  2. Plugin Manager Receives A Measurement - Plugin Manager (pluginmgr) reads the standard out from the meter plugin. Receipt of the measurement from a meter plugin is describe in

  3. Plugin Manager Sends Measurement - Plugin Manager writes the measurement to the meter via the Meter(boundary-meter) JSON RPC channel

  4. Meter Receives A Measurement - Meter receives an JSON RPC call sent by the Plugin Manager.

  5. Meter Sends A Measurement - Meter sends the measurement to TrueSight Pulse via an HTTPS Rest call.
