Docker-monitor architecture

• docker-monitor: The main service that polls running containers, pushes data to influx and listens for request from client

• influxdb: Time-series database used to store metrics of the containers

Getting started with docker-monitor

1. Checkout the deployment files:

git clone https://github.com/hackathon-2K17-CloudConquerors/docker-monitor.git
cd docker-monitor/deployments/docker-compose

2. Create the configuration file: (keeping everything by default should be fine)

modify entries in config.env

3. Start the containers:

docker-compose up
