At_Swarm_Load

Source files for Docker image used to send GCE Custom metrics for 5m load average and root volume utilisation.

Why, What, How?

Why?

We want to have load average and disk utilisation on the monitoring dashboard, but the Google Ops Agent sends too much data, and Flatcar doesn't support it anyway.

What?

This project uses Python3 in order to incorporate the google-cloud-monitoring pip library.

Scripts are based on Getting started with Google Cloud Monitoring by Arpana Mehta

How?

The Dockerfile is built using:

sudo docker build -t atsigncompany/at_swarm_load .

and then pushed to Docker Hub with:

sudo docker push atsigncompany/at_swarm_load

it can then be installed and run on Swarm nodes with:

sudo docker run -d --restart unless-stopped atsigncompany/at_swarm_load

AWS

A version has also been created for AWS VMs. It needs a service account key as a .json file to replace the placeholder.

First install dependencies:

sudo apt install python3-pip
pip3 install --no-cache-dir google-cloud-monitoring

Then copy over the files in the aws directory to their respective places on the Ubuntu VM filesystem. sudo will be needed to copy the systemd service definition into place.

Finally enable and start the service:

sudo systemctl enable gcp-mon.service
sudo systemctl start gcp-mon.service
