5GTANGO/SONATA service platform monitoring client is used in order to gather monitoring data from VM and containers which hosts Sonata's services and push them to the monitoring server.

Supported monitoring metrics are:

VM metrics

  • cpu usage
  • memory usage
  • disk usage
  • network traffic

Container metrics

  • cnt_cpu_perc
  • cnt_mem_perc
  • cnt_mem_limit_MB
  • cnt_mem_usage_MB
  • cnt_net_rx_MB
  • cnt_net_tx_MB
  • cnt_block_ou_MB
  • cnt_block_in_MB
  • cnt_created
  • cnt_status

Dependencies

  • python 2.7
  • docker-engine 1.10.2

Installation

Build container

git clone https://github.com/sonata-nfv/son-monitor-probe.git
cd son-monitor-probe
sudo docker build -f sp_mon/Dockerfile -t son-sp-mon .

Run monitoring probe as container

sudo docker run --net="host" -e "NODE_NAME=INT-SRV-1" -e "PROM_SRV=http://sp.int2.sonata-nfv.eu:9091/metrics" --privileged=true -d -v /var/run/docker.sock:/var/run/docker.sock -v /proc:/myhost/proc -v /:/rootfs:ro son-sp-mon

Usage

All metrics are exposed to the Pushgateway server.

Get last pushed value of VMs cpu usage

Request:

curl http://<pushgateway>:9091/metrics | grep vm_cpu_perc

Response:

# TYPE vm_cpu_perc gauge
