Telemetry

Tools to collect telemetry from hICN forwarders.

Introduction

The project containes two plugins for collectd:

  • vpp: to collect statistics for VPP

  • vpp-hicn: to collect statistics for hICN

Currently the two plugins provide the followign funtionalities:

  • VPP: statistics (rx/tx bytes and packets) for each available interface.

  • HICN-VPP: statistics (rx/tx bytes and packets) for each available face.

Quick Start

From the code tree root

$ cd telemetry
$ mkdir -p build
$ cd build
$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr
$ make
$ sudo make install

Using hICN collectd plugins

Platforms

  • Ubuntu 18.04 LTS (x86_64)

  • Debian Stable/Testing

  • Red Hat Enterprise Linux 7

Dependencies

Build dependencies:

  • VPP 20.01

    • DEB packages (can be found https://packagecloud.io/fdio/release/install):

    • vpp

    • libvppinfra-dev

    • vpp-dev

    • hicn-plugin-dev

Getting started

Collectd needs to be configured in order to use the hICN collectd plugins. The configuration can be achieved editing the file ‘/etc/collectd/collectd.conf’ and adding the following lines:

LoadPlugin vpp
LoadPlugin vpp_hicn

Before running collectd, a vpp forwarder must be started. If the vpp-hicn plugin is used, the hicn-plugin must be available in the vpp forwarder

Example: use rrdtool and csv plugin to store statistics from vpp and vpp-hicn plugins

Edit the configuration file as the following:
