5GTANGO/SONATA VIM monitoring client is used in order to gather monitoring data from VIM infrastructure (openstack) and push them to the monitoring server

Supported monitoring metrics are:

  • Total/used Cores
  • Total/used Instances
  • Total/used RAM size
  • Total/used Floating IPs

Dependencies

  • python 2.7

Installation

From code

a. Set configuration file (odc.conf)

[Openstack]
controller_ip: <controller_ip>
keystone_url: http://<keystone_ip>:5000/v2.0/tokens
tenants:  [{"name": "admin","user_name": "name","password": "password","pushgw_url": ["http://<pushgateway>:<port>/metrics"]}]
node_name: pop_vim

b. Execute the probe

sudo python opensdatacollector.py

Usage

All metrics are exposed to the Pushgateway server.
