Memory Usage as CSV¶

This document describes an Ansible playbook that generates a CSV file containing detailed information about the memory reserved for an application.

About the Generated CSV¶

The information is provided as CSV and contains these columns:

Column	Description
Installation	Installation name.
Memory (MiB)	This is the amount of memory requested on Kubernetes. This should be about ~80% of the memory that’s actually being used. The rest is spare to be able to deal with spikes in usage.

Hint

This documentation assumes you’ve setup Ansible already. See Setup Ansible.

Generate CSV:

cd ${ANSIBLE_REPO}/tocco
ansible-playbook playbooks/memory_usage.yml -e output=data.csv -f 50

This stores the CSV file at playbooks/data.csv.
