Snap collector plugin - ethtool

This plugin uses ethtool to gather interface statistics. Current version exposes stats available using ethtool given by below commands:

  • ethtool -S, interface statistics
  • ethtool -d, register dump
  • ethtool -m, digital optical monitoring

It's used in the Snap framework.

Getting Started

The plugin is ready to use out of the box by following the system requirements. You don't have to perform any configuration or installation steps.

System Requirements

  • ethtool available under $PATH or /sbin/
  • golang 1.5+ (needed only for building)
  • Root privileges are required

Operating systems

All OSs currently supported by plugin:

  • Linux/amd64

Installation

Download the plugin binary:

You can get the pre-built binaries for your OS and architecture from the plugin's GitHub Releases page. Download the plugin from the latest release and load it into snapteld (/opt/snap/plugins is the default location for Snap packages).

To build the plugin binary:

Fork https://github.com/intelsdi-x/snap-plugin-collector-ethtool Clone repo into $GOPATH/src/github.com/intelsdi-x/:

$ git clone https://github.com/<yourGithubID>/snap-plugin-collector-ethtool.git

Build the Snap ethtool plugin by running make within the cloned repo:

$ make

This builds the plugin in ./build/

Documentation

You can learn about some of the exposed metrics here.

Collected Metrics

This plugin allows to collect interface network statistics such like received|transmitted bytes|packets and more.
List of metrics for each device is dependent on its driver.

This plugin has the ability to gather the following metrics (driver specific):

A few drivers such as IXGBE support exposing optical transceivers (SFP, SFP+, or XFP) information too. The information is known as [digital optical monitoring (DOM)] (METRICS_DOM.md#digital-optical-monitoring) information.

Metrics are available in namespace:

  • /intel/net/<driver name>/<device name>/nic/<metric name> (from cmd ethtool -S, interface statistics)
  • /intel/net/<driver name>/<device name>/reg/<metric name> (from cmd ethtool -d, register dump)
  • /intel/net/<driver name>/<device name>/dom/<metric name> (from cmd ethtool -m, digital optical monitoring)

Examples

Example of running Snap ethtool collector and writing data to file.

Ensure Snap daemon is running:

  • initd: service snap-telemetry start
  • systemd: systemctl start snap-telemetry
  • command line: snapteld -l 1 -t 0 &

Download and load Snap plugins:

$ wget http://snap.ci.snap-telemetry.io/plugins/snap-plugin-collector-ethtool/latest/linux/x86_64/snap-plugin-collector-ethtool

$ chmod 755 snap-plugin-*
$ snaptel plugin load snap-plugin-collector-ethtool
$ snaptel plugin load snap-plugin-publisher-file

Roadmap

As we launch this plugin, we have a few items in mind for the next release:

  • [ x ] Metrics from device's registry dump when using IXGBE driver
  • [ x ] Expose pluggable optics (SFP & SFP+) information

If you have a feature request, please add it as an issue.
