Azure Cost CLI

This is a simple command line tool to get the cost of your Azure subscription. It uses the Azure Cost Management API to get the cost and output the results to the console, text, csv, markdown or JSON. E.g. so it can be used in a workflow to get the cost of your subscription and use it in subsequent steps.

Besides showing the accumulated cost, it can also show daily cost, extract resource (costs) and list budgets.

It can also detect anomalies and trends in the cost, which can be used to further automate reporting.

Installation

You can install this tool globally, using the dotnet tool command:

dotnet tool install --global azure-cost-cli 

Upgrading

When there is a new version available on NuGet, you can use the dotnet tool update command to upgrade:

dotnet tool update --global azure-cost-cli 

With a --version parameter, you can specify a specific version to install. Use the --no-cache parameter to force a re-download of the package if it cannot find the latest version.

Usage

You can invoke the tool using the azure-cost command. You can use the --help parameter to get a list of all available options. Some of the commands have additional parameters which can be shown by adding the specific command with the --help option.

azure-cost --help

Which will show:

Starting from version 0.35, you can select a different scope besides only subscription. Specify subscription id and resourcegroup name, billing account and/or enrollment account to scope the request to that level.

When you do not specify a subscription id, it will fetch the actively selected one of the az cli instead.

If the application is not working properly, you can use the --debug parameter to increase the logging verbosity and see more details.

This tool uses the Azure Cost Management API to get the cost. Not all subscriptions have access to this API. To check if your subscription has access, you can use the az account subscription show --subscription-id yourid --query '[subscriptionPolicies.quotaId]' -o tsv command. Validate the resulting quota id with the ones on the Microsoft list to see if it is supported. Running the tool with the --debug parameter will also show the quota id that is used.

There is a pretty strict rate limit on the cost api; the calls are retried after a 429 is received, but it might take a while before the call succeeds as it honors the retry time out.

Authentication

To make the call to the Azure cost API, you do need to run this from a user account with permissions to access the cost overview of the subscription. Further more, it needs to find the active credentials and it does so by using the ChainedTokenCredential provider which will look for the az cli token first. Make sure to run az login (with optionally the --tenant parameter) to make sure you have an active session.

Use in a GitHub workflow

You can use this tool in a GitHub workflow to get the cost of your subscription and store the results in markdown as a Job Summary. This can be used to get a quick overview of the cost of your subscription. Have a look at the workflow in this repository for an example output.

name: Azure Cost CLI Workflow

on:
  workflow_dispatch:
    inputs:
      az-subscription-id:
        description: 'Azure Subscription ID'
        required: true
jobs:
  run-azure-cost-cli:
    runs-on: ubuntu-latest
    steps:
      - name: Azure Login
        uses: azure/login@v1
        with:
          creds: ${{ secrets.AZURE_CREDENTIALS }}

      - name: Install Azure Cost CLI
        run: dotnet tool install -g azure-cost-cli

      - name: Run Azure Cost CLI
        run: azure-cost accumulatedCost -o markdown --subscription ${{ github.event.inputs.az-subscription-id }} >> $GITHUB_STEP_SUMMARY

The last step output the markdown to the Job Summary. This can be used to show the cost of the subscription in the workflow summary. Use it on a schedule to get for example a daily overview. Alternatively you can use the -o json parameter to get the results in JSON format and use it for further processing.

Available commands

Accumulated Cost

This will retrieve the accumulated cost of the subscription. This is the total cost of the subscription since the beginning of the period specified. We will try to fetch the forecast as well and organise by location, type and resource group. You can use the different formatters to get the results in different formats.

azure-cost accumulatedCost -s 574385a9-08e9-49fe-91a2-27660d92b8f5

This is the default command when you do not specify a command.

Cost By Resource

This will retrieve the cost of the subscription by resource. This will fetch the resource details including the meter information. It is up to the formatter how this is returned. Use the json formatter to get the full details.

azure-cost costByResource -s 574385a9-08e9-49fe-91a2-27660d92b8f5 -o json

If you are only interested in the cost of the resources, you can exclude the meter details using the --exclude-meter-details parameter.

azure-cost costByResource -s 574385a9-08e9-49fe-91a2-27660d92b8f5 --exclude-meter-details

Do keep in mind that with the --metric you can either request the ActualCost or the AmortizedCost cost, but not both at the same time. The default is ActualCost.

A resource can be in multiple resource locations, like Intercontinental and West Europe. When you use --exclude-meter-details, the resource will be listed once and the locations will be combined.

You can parse out the resource name, group name and subscription id from the ResourceId field. The format is /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/{resourceProviderNamespace}/{resourceType}/{resourceName}.

Cost By Tag

This will retrieve the cost of the subscription by the provided tag key(s). So if you tag your resources with, e.g. a cost-center or a creator, you can retrieve the cost of the subscription by those tags. You can specify multiple tags by using the --tag parameter multiple times.

azure-cost costByTag  --tag cost-center --tag creator

The csv, json(c) and console output will render the results, either hierarchically or flattened in the case of the csv export.

If you require more formatters, let me know!

Daily Costs

The daily overview fetches the cost of the subscription for each day in the specified period. It will show the total cost of the day and the cost per dimension. The dimension is the resource group by default, but you can specify a different one using the --dimension parameter.

For example:

azure-cost dailyCosts -s 574385a9-08e9-49fe-91a2-27660d92b8f5 --dimension ResourceLocation

The default dimension is the resource group.

azure-cost dailyCosts 

The above screenshots show the default console output, but the other formatters can also be used.

The available dimensions are: ResourceGroup,ResourceGroupName,ResourceLocation,ConsumedService,ResourceType,ResourceId,MeterId,BillingMonth,MeterCategory,MeterSubcategory,Meter,AccountName,DepartmentName,SubscriptionId,SubscriptionName,ServiceName,ServiceTier,EnrollmentAccountName,BillingAccountId,ResourceGuid,BillingPeriod,InvoiceNumber,ChargeType,PublisherType,ReservationId,ReservationName,Frequency,PartNumber,CostAllocationRuleName,MarkupRuleName,PricingModel,BenefitId,BenefitName

Include Tags

This option allows to include the dimensions' Tags in the same row. Tags allow cost analysis customization. Adding the Tags from the dimension allows complementary analysis in tools like Power BI. This option is enabled for DailyCost report and for Json, JsonC, and Csv expor formats. Using other formats, ignores the option.

The following query shows the daily costs for subscription x group by resource group name including the tags for the resource group ready to export to Csv:

azure-cost dailyCosts -s XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX --dimension ResourceGroupName --includeTags -o Csv

That would extend into a column called Tags the resource group tags in Json format:

[""\""cost-center\"":\""my_cost_center\"""",""\""owner\"":\""[email protected]\""""]

Note that the Json column should be parsed in the analytical tool.

Detect Anomalies

Based on the daily cost data, this command will try to detect anomalies and trends. It will scan for the following anomalies:

• Cost that is stopped; although it is good that the cost is stopped, it might be an indication that something is wrong.
• Cost that is appearing; the cost was not there before and is now adding to the overall cost.
• A spike in cost; a deviation from the normal cost pattern
• A gradual increase in cost; so a service is growing in cost over time.

There are a number of settings you can use to finetune the detection.

--dimension               ResourceGroupName    The grouping to use. E.g. ResourceGroupName, Meter, ResourceLocation, etc. Defaults to ResourceGroupName                                               
--recent-activity-days    7                    The number of days to use for recent activity. Defaults to 7                                                                                           
--significant-change      0,75                 The significant change in cost to use. Defaults to 0.75 (75%)                                                                                          
--steady-growth-days      7                    The number of days to use for steady growth. Defaults to 7                                                                                             
--threshold-cost          2                    The thresshold cost to use. Values lower than this are excluded. Defaults to 2.00      

All the different formatters can be used to output the data, so you can further process it with the JSON or CSV output, send it via email with the text formatter, or use the markdown formatter to include it in a GitHub workflow. The console output will render the different anomalies in different and point out the moment in time where the anomaly was detected.

azure-cost detectAnomalies

Budgets

This will retrieve the available budgets for the subscription. It will show the current status of the budget and the amount of the budget. As well as listing the configured notifications.

azure-cost budgets -s 574385a9-08e9-49fe-91a2-27660d92b8f5 

Regions

Retrieve a list of available regions. Besides the location and supported compliances, it will also show the available sustainability information.

azure-cost regions

Not all the formatters are supported for this command. Let me know if there is a need.

What-if scenarios

This command allows you to run what-if scenarios. It will show the cost of the subscription if you would make changes to either usage or rates.

Regions

The what-if regions command compares your virtual machines in the given subscription with prices of the same virtual machine in different regions. It will show the current cost and the cost if you would move the virtual machine to a different region.

azure-cost what-if regions

A typical output to the console might be like this:

Prices per region for a914b3f4-fe8b-4e94-a0d3-2938540d59c6 between 01/09/2023 and 05/10/2023

You can also output to csv or json for further processing. It uses the usageDetails endpoint, which provided different type of data than the query endpoint.

Filter

With the --filter option you can pass in one or more properties to filter on.

azure-cost --filter "ResourceGroupName=yourresourcegroup;myresourcegroup" --filter "owner=me" 

In the example above, we look for resources in either yourresourcegroup or myresourcegroup and having a tag named owner with the value me.

Filters are passed along to the Cost API, so less data is retrieved. Compared to the query, where the data is queried with a JMESPATH expression and can be projected as well.

Multiple filters are combined with an and expression, while the values are split by the ; and used as an or.

Query

Use the --query to specify a JMESPath expression. This allows you to filter the results. For example, to get the yesterday cost of the subscription, you can use the following query:

azure-cost -s 574385a9-08e9-49fe-91a2-27660d92b8f5 -o json --query "totals.yesterdayCost"

Or to list only the resource groups:

azure-cost -s 574385a9-08e9-49fe-91a2-27660d92b8f5 -o json --query "ByResourceGroup[*].[ResourceGroup, Cost]"

will output:

[["mindbyte-sand-api",28.94824],["rg-test",16.457219149662315],["rg-weu",0.252499694771765],["cloud-storage-westeu",0.183537445632]]

For the JMESPath parsing, it uses the JMESPath.Net library. Not all constructions might be implemented yet. If you find a query that does not work, please open an issue with a reproducable path at their repo.

Timeframe

The default timeframe is the billing month to date. You can specify a custom timeframe using the --from and --to parameters and setting the -t custom. The timeframe is specified in the ISO 8601 format.

Other options are:

• BillingMonthToDate
• Custom
• MonthToDate
• TheLastBillingMonth
• TheLastMonth
• WeekToDate

These options are based on the types exposed by the query API.

Output formats

The tool supports multiple output formats. The default is Console which will output the results to the console. You can specify a different format using the --output parameter. The different commands generate different outputs using the specified formatter. The following formats are supported:

Console

The default output format. It will output the results to the console in a graphical way. For example the accumulated costs:

Json / JsonC

The Json format is great for further processing of the data. It will output the results in a JSON format to the console. Using the > operator, you can redirect the output to a file. Use jsonc to get a colorized output.

Csv

A CSV format. It will output the results in a CSV format which can be used in Excel or other tools. It will use the default culture of your system to format the numbers. If you combine the output of multiple runs into one file (like using the >> to append to a file), you can use the --skipHeader parameter to prevent the header from being written multiple times.

Iterate over multiple subscriptions

Since the tool operates on a single subscription only, you will need to loop over multiple subscriptions yourself. You can do this by using the az account list command and then using the --subscription parameter to switch between subscriptions.

az account list --query "[].id" -o tsv | while read -r id; do
    echo "Subscription: $id"
    azure-cost accumulatedCost -o markdown -s $id
done

Or using Powershell

az account list --query "[].id" -o tsv | ForEach-Object {
    Write-Host "Subscription: $_"
    azure-cost accumulatedCost -o markdown -s $_
}

Or this snippet by @EEN421 to get the cost by resource for each subscription and append it to a single CSV file.

#Connect to Azure
Connect-AzAccount -UseDeviceAuthentication -Tenant xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx

#Pull list of Subscriptions
$ids = Get-AzSubscription -TenantId xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx| Select-Object id,name
$firstid = $ids | Select-Object -first 1
$remainingids = $ids | Select-Object -skip 1

#Create CSV for first subscription with header
$firstoutput = azure-cost costByResource -s $firstid.id -t Custom --from 2023-05-01 --to 2023-05-31 -o csv
Add-Content ".\report.csv" $firstoutput

#Loop through remaining subscriptions and append to CSV
Foreach ($id in $remainingids) {
$output = azure-cost costByResource -s($id.id) -t Custom --from 2023-05-01 --to 2023-05-31 -o csv --skipHeader
Add-Content ".\report.csv" $output
}

Using the --skipHeader parameter is important here, otherwise you will get a header for each subscription which will mess up the output file as it will append the data to the same file.

Is there cost involved?

No, the calls to the Azure Cost APIs are free, although there are some rate limits in place. Avoid pulling data too often as it will only be refreshed every 4 hours.
