Azure Request Limitometer
NOTE: This software is provided AS IS.
This program makes requests to the Azure Resource Manager API in order to get the headers of the remaining requests available to the API. This is important as if we reach the limit, Kubernetes is no longer functioning properly as it cannot make requests to Azure.
We authenticate with the Managed Service Identity of the VMs running in Azure.
There are curerntly two supported output logic: influxdb and pushgateway
The influxDB format is the following:
> select * from "Microsoft.Compute/HighCostGet3Min" limit 5
name: Microsoft.Compute/HighCostGet3Min
time requestsRemaining

Building the project
The quickest way to build the project is building it with Docker by running the following command on your computer.
docker build -t azure-request-limitometer .
If you want to do it without Docker, you must first make sure you have dep.
go get -u github.com/golang/dep/cmd/dep
From there simply run the following command from your computer.
go build azure-request-limitometer/cmd/limitometer
