This repository provides an end-to-end solution to gather some GCP networking quotas, limits, and their corresponding usage, store them in Cloud Operations timeseries which can displayed in one or more dashboards or wired to alerts.
The goal is to allow for better visibility of these limits, some of which cannot be seen in the GCP console today, facilitating capacity planning and being notified when actual usage approaches them.
The tool tracks several distinct usage types across a variety of resources: projects, policies, networks, subnetworks, peering groups, etc. For each usage type three distinct metrics are created tracking usage count, limit and utilization ratio.
The screenshot below is an example of a simple dashboard provided with this blueprint, showing utilization for a specific metric (number of instances per VPC) for multiple VPCs and projects:
One other example is the IP utilization information per subnet, allowing you to monitor the percentage of used IP addresses in your GCP subnets.
More complex scenarios are possible by leveraging and combining the 50 different timeseries created by this tool, and connecting them to Cloud Operations dashboards and alerts.
Refer to the [Cloud Function deployment instructions](./deploy-cloud-function/) for a high level overview and an end-to-end deployment example, and to the[discovery tool documentation](./src/) to try it as a standalone program or to package it in alternative ways.
