+# Telemetry
+
+Tools to collect telemetry from hICN forwarders.
+
+## Introduction ##
+
+The project containes two plugins for [collectd](https://github.com/collectd/collectd):
+* vpp: to collect statistics for VPP
+* vpp-hicn: to collect statistics for [hICN](https://github.com/FDio/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 ###
+
+hICN collectd plugins have been tested in:
+
+- Ubuntu 16.04 LTS (x86_64)
+- Ubuntu 18.04 LTS (x86_64)
+- Debian Stable/Testing
+- Red Hat Enterprise Linux 7
+- CentOS 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:
+
+```
+######################################################################
+# Global #
+######################################################################
+FQDNLookup true
+BaseDir "/collectd"
+Interval 2
+
+######################################################################
+# Logging #
+######################################################################
+LoadPlugin logfile
+
+<Plugin logfile>
+ LogLevel "info"
+ File "/var/log/collectd.log"
+ Timestamp true
+ PrintSeverity true
+</Plugin>
+
+######################################################################
+# Plugins #
+######################################################################
+LoadPlugin csv
+LoadPlugin rrdtool
+LoadPlugin vpp
+LoadPlugin vpp_hicn
+
+######################################################################
+# Plugin configuration #
+######################################################################
+<Plugin csv>
+ DataDir "/collectd/csv" # the folder under which statistics are written in csv
+ StoreRates true
+</Plugin>
+
+<Plugin rrdtool>
+ DataDir "/collectd/rrd" # the folder under which statistics are written in csv
+</Plugin>
+```
+
+Run vpp and collectd
+
+```
+$ systemctl start vpp
+$ systemctl start collectd
+```
