Influxdb-Grafana-Docker-Ansible

This repositor aims to automate deployment of monitoring stack based on Influxdb, Grafana using Docker automated by Ansible.

PS: Ansible automation comming soon

Requirements

• Docker Engine
• Docker Compose

Deploy the service

• Add storage devices for persistent storage for influxdb and grafana.
• # docker-compose up -d

Configure Influxdb

Execute the following commands from the node where influxdb container is running

• Create influxdb database

curl -G http://localhost:8086/query --data-urlencode "q=CREATE DATABASE collectd" 

• Verify database

curl -G 'http://localhost:8086/query?pretty=true' --data-urlencode "q=SHOW DATABASES" ``

• Apply OS tuning

echo "net.core.rmem_max=26214400" >> /etc/sysctl.conf
echo "net.core.rmem_default=26214400" >> /etc/sysctl.conf
sysctl -p /etc/sysctl.conf

• Influxdb should be running at http://127.0.01:8083/

Configure Grafana

Execure the following commands from the node where Grafana conatiner is running

• Add Grafana datasource

 curl 'http://admin:admin@127.0.0.1:3000/api/datasources' -X POST -H 'Content-Type: application/json;charset=UTF-8' --data-binary '{"name":"influxdb","type":"influxdb","url":"http://influxdb:8086","access":"proxy","isDefault":true,"database":"collectd"}' 

• Verify Grafana Datasource

curl 'http://admin:admin@127.0.0.1:3000/api/datasources' 

• Grafana should be running at http://127.0.0.1:3000

Setup Collectd

yum install -y collectd

• Configure collectd

# wget https://raw.githubusercontent.com/deniszh/collectd-iostat-python/master/collectd_iostat_python.py -O /usr/lib64/collectd/collectd_iostat_python.py
# chmod 755 /usr/lib64/collectd/collectd_iostat_python.py
# wget https://raw.githubusercontent.com/deniszh/collectd-iostat-python/master/iostat_types.db -O /usr/share/collectd/iostat_types.db

• Copy collectd configuration file

cp collectd/collectd.conf /etc/collectd.conf

• Edit collectd configuration file , Under <write_graphite> plugin and change

  • Node Name
  • Host Name
  • Prefix

• Start collectd service

systemctl start collectd; systemctl enable collect

Query Influxdb for data

• Login to influxdb web interface and run query show series from collectd
