Virtual Tags

Virtual Tags are custom tags created within the platform to help you organize, filter, and report on cloud resources—even if those resources don't have native tags applied. They provide flexibility in how you assign metadata to resources, helping improve visibility, cost attribution, and governance.

You can create two types of Virtual Tags:

• Standard – Manually assign a specific tag key and value to a defined set of resources.

• Rule-Based – Automatically generate or standardize tags based on defined logic, conditions, or patterns.

Virtual Tags do not modify the actual resource tags in your cloud provider. Instead, they live within the platform and are applied virtually to support better analytics and reporting..

Steps to create a Virtual Tags

1. Login to Mavvrik

2. Click on Menu

3. Navigate to the Admin section on the sidebar and select "Virtual Tags."

Creating a Standard Virtual Tag

Standard Virtual Tags allow you to manually assign a specific tag key and value to selected resources for a defined time period. Follow the steps below to create one:

1. Navigate to Create Virtual Tag

Open the Virtual Tag creation panel. You'll see three tabs at the top: Setup, Scope, and Rule.

2. Select Tag Type

In the Setup tab:

• From the Type dropdown, select Standard.

• Enter the desired Key and Value for your tag.

  • Example: Key = Environment, Value = QA

• Optionally, add a Description to explain the purpose of the tag.

• Define the Start Month and End Month to set the active period for this tag.

Click Next to proceed.

3. Define Tag Scope

In the Scope tab:

• Choose the Data Source (e.g., Cloud, AI, K8s, VMware,SaaS).

• Select filter options such as:

  • Provider (e.g., AWS, Azure, GCP)

  • Billing Account

  • Usage Account

  • Resource Group

  • Location

• You can use Basic or Advanced filters based on your tagging needs.

• Optional: Enable Dynamic Filter for more flexible targeting.

4. Create the Tag

Once all fields are filled out:

• Click Create to save your Virtual Tag

• The tag will be applied to all matching resources within the selected scope and date range.

5. New Virtual Tag is created and displayed as shown below.

After creating the Virtual Tags, click on "Run Ingestion" and wait for the process to complete. Once done, perform a hard refresh on the page.

If you configure invalid tag parameters using basic and advanced filters error message is displayed.

Creating a Rule-Based Virtual Tag

Rule-Based Virtual Tags allow you to automatically generate, clean up, or standardize tags using smart logic such as tag key/value mappings or RegEx patterns. This reduces manual effort and improves tag consistency across your cloud environment.

You can use Rule-Based Virtual Tags to:

• Standardize inconsistent tag keys and/or values

• Create dynamic tags based on resource attributes using RegEx

• Apply complex tagging logic that adapts to your environment

1. Navigate to Create Virtual Tag

Open the Virtual Tag creation panel. You'll see three tabs: Setup, Scope, and Rule.

2. Select Tag Type

In the Setup tab:

• From the Type dropdown, choose Rule Based

• Enter an optional Description for your tag

• Set the Start Month and End Month to define the active period of the rule

• Click Next to proceed

3. Define Tag Scope

In the Scope tab:

• Choose the Data Source relevant to your tag (e.g., Cloud, K8s, AI, Databricks, MongoDB etc.)

• Use Basic or Advanced filters to define the resources this rule applies to

• Filter options include:
  • Provider
  • Billing Account
  • Usage Account
  • Resource Group
  • Location

• (Optional) Enable Dynamic Filter for attribute-based matching

• Click Next to continue

4. Choose a Rule Type

In the Rule tab, select the logic that fits your tagging needs. Available options include:

• Standardize Tag Keys Only
  • Use when you have inconsistent tag keys like Env, ENV, or Environment
  • Example: All keys are standardized to ENVIRONMENT, while keeping their values (e.g., prod, dev) unchanged

• Standardize Tag Values Only
  • Use when tag keys are consistent but values vary
  • Example: Values like prod-root, prod-tenant are standardized to prod, while keeping the original key (Environment)

• Standardize Tag Keys & Values
  • Use when both tag keys and values are inconsistent
  • Example: env or Env → Environment, and qa-root, qa-tenant → QA

• Dynamic Virtual Tags
  • Use when you want to extract tag values from resource attributes using RegEx.
  • Example: From usage_type:BoxUsage:t4g.medium, extract t4g.medium as the tag value for the key instance_type

• List of fields customers can use in dynamic virtual tags:

1. Provider

2. Billing Account

3. Usage Account

4. Resource Group

5. Category

6. Location

7. Service Category

8. Service

9. SKU

10. Cost Type

11. Billing Entity

12. Instance Type

5. Finalize and Create

Once your rule is fully configured:

• Click Create to save and apply the rule

• The system will evaluate all matching resources and apply the virtual tag based on the logic and scope you defined

1. Click on Menu

2. Navigate to the Inform section on the sidebar and select "Cost"

3. Click on Filters

4. Scroll down to bottom of cost filters

5. Click on Virtual Tags option and select required Virtual Tags

6. Click on Apply.

Clone Virtual Tags

Clone an existing virtual tag to quickly create a new one with the same setup already in place.
This is useful when you need a similar view for another team, business unit, environment, or customer use case.
Instead of rebuilding filters and structure from scratch, you can start with a copied version and make only the needed changes.
The cloned virtual tag is independent, so updates to it do not affect the original.

1. Click on Menu

2. Navigate to the Admin section on the sidebar and select "Virtual Tags."

3. Click on Clone icon (You can see same filtered options selected)

4. Edit the required filters and create

5. Click Next -> Create

FAQs

Does creating a Virtual Tag change the actual tags on my cloud resources?
No. Virtual Tags never modify anything in your cloud provider — they exist entirely within Mavvrik and are applied virtually, purely to support cost allocation, filtering, and reporting inside the platform.

Which pages can I actually use Virtual Tags on?
Cost, AI Cost, Resources, Cost Variance, K8s Cost, Datacenter Cost, and Coverage. If you've created a tag but don't see it as a filter option somewhere else, that page likely isn't one of these.
