Deploy with Docker Compose

On a host wich Docker and Docker Compose, checkout this repository, open a terminal inside your git clone and then run

docker-compose up -d

Make sure to change the password for the influxdb in the docker-compose.yml file. If you do so, you need to change it in logstash/pipeline/kvmtop2influxdb.conf as well, and rebuild the logstash container image by yourself.

Then on a kvm enabled host, start kvmtop and send the output to your logstash instance, e.g.

kvmtop --cpu --printer=json --output=tcp --target=127.0.0.1:12345
