Azure Metrics for quotas along with alerts and dashboards

Geek Repo:Geek Repo

Github PK Tool:Github PK Tool

Docker Image Version (latest by date)

Goal

Create easy to use collectors(prometheus / opentelemetry), alerts, and dashboards for Azure Quota metrics.

To help ensure that you are staying within appropriate quotas or limits for your azure resources.

TODO

  • Create Source code to get summary page metrics
  • Create Source code to get traffic manager metrics
  • create source code to get role assignment metrics
  • create docker file
  • auto detection of current location
  • create online repository location for docker file
  • create grafana chart
  • create alert manager alerts
  • explain how to install in prometheus
  • Create helm chart / k8s install directions to ease installation
  • Figure out minimal permissions needed
  • add images for windows & arm64
  • add dependabot
  • add release / publishing scripts
  • add more items

Configuration

How to configure this docker container / asp.net app

Command line

# dotnet .\bin\Debug\net6.0\metrics.dll -?
Usage: metrics [options]

Options:
  -s|--subscription <SUBSCRIPTION>  Required. The Subscription id(s).
                                    Ex: '--Subscription abcdef01-0123-0123-0123-0123456789ab'.
                                    Can be specified more than once for multiple values
  -l|--location <LOCATION>          Required. The region name(s).
                                    Ex: '--Location EastUS'.
                                    Can be specified more than once for multiple values
  -a|--arm-limit <ARM_LIMIT>        Optional. Additional ARM type(s) to monitor <ArmType=LimitValue>.
                                    Ex: '--ArmLimit Microsoft.Network/trafficManagerProfiles=200'.
                                    Can be specified more than once for multiple values
  -?|-h|--help                      Show help information.

Environment Variables

https://learn.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-6.0#environment-variables-set-in-generated-launchsettingsjson

You can configure client auth if not using AAD Pod identity.

Environment Variable Name value
AZURE_TENANT_ID tenantId
AZURE_CLIENT_ID clientId
AZURE_CLIENT_SECRET secret

AppSettings

see metrics/appsettings.json contains application port (8080)

Example metrics

The goal is to create X_quota and X_limit such that you can set alerts for X_quota / X_limit >=.8 to know when you are running low on capacity

Note by default metrics with a 0 reading are filtered out

Below is a list of sample metrics

Dashboard

Here is a simple exported Dashboard from grafana grafana/exported.json

charts of quota visualized

Alerts

Here is a sample prometheus alert manager alert file alerts/alerts.yaml

Kubernetes Installation

You have to figure out how to Authenticate to Azure, you can use something like https://github.com/Azure/aad-pod-identity or you can use client secrets (see comments in deployment.yaml).

Ensure to update deployment.yaml to point to region (not just westus) if you wish to target a different region for your stats & update it for your subscription id.

kubectl apply -f install/kubernetes/service.yaml
kubectl apply -f install/kubernetes/deployment.yaml

Prometheus Scrape Config

Ensure that you have updated your prometheus config to contain something like this

scrape_configs:
- job_name: 'azure-quota-metrics'
  scrape_interval: 60s
  scrape_timeout: 60s
  scheme: http
  metrics_path: '/metrics'
  static_configs:
  - targets: ['azure-quota-metrics.default.svc.cluster.local:8080']

Build

docker build . -t knicknic/azure-quota-metrics && docker push knicknic/azure-quota-metrics
