How to audit Kubernetes namespace costs with your AI

Connect OpenCost to your AI client to turn cluster metrics into actionable cost reports. Once connected, your agent handles the data retrieval for you.

Short answer

How can I find out which Kubernetes namespaces are costing me the most?

Your AI uses the OpenCost connection to pull cost allocations for every namespace and pod. It identifies the biggest spenders and provides a granular breakdown of your cluster usage.

Where your data lands.

The outcomes of your audit.

The AI processes raw cluster data into these specific results.

COST

Namespace spend totals

The AI pulls the exact dollar amount spent per namespace. You get a clear list of your most expensive environments.

PODS

Granular pod breakdown

Your agent drills down from the namespace level to specific pods. This shows you exactly which workloads are driving up your bill.

TRENDS

Usage patterns

The AI looks for spikes in resource consumption. You'll see which namespaces are growing in cost over time.

HUMAN

Optimization decisions

The AI presents the data, but you decide which pods to resize or terminate. You keep full control over your cluster configuration.

The workflow

What your AI does when the data arrives.

The AI acts as a data analyst for your Kubernetes cluster.

  1. Fetch cluster data

    The AI pulls the current cost distribution across your entire cluster.

    get_allocation

  2. Group by namespace

    It aggregates the raw data to show you the total cost for every namespace.

    get_allocation

  3. Identify outliers

    The agent flags namespaces or pods that are consuming disproportionate amounts of resources.

    get_allocation

  4. Summarize findings

    The AI translates the technical cost metrics into a plain English report for you.

    get_allocation

  • Show me a breakdown of costs by namespace in my current cluster.

  • Which pods in the 'production' namespace are driving the highest costs?

  • List the top 5 most expensive namespaces right now.

  • Compare the cost of the 'staging' namespace against the 'development' namespace.

FAQ

How this task behaves.

  • 01

    Can the AI change my Kubernetes resource limits?

    No. The AI can only read cost data through the OpenCost connection. You must manually adjust limits in your cluster.

  • 02

    Does the AI see my actual application code?

    No. The AI only accesses the cost and resource allocation data provided by OpenCost.

  • 03

    Can I ask for cost trends over the last month?

    Yes, as long as your OpenCost instance has that historical data available for the AI to read.

  • 04

    Will the AI delete any pods to save money?

    No. The AI has no permission to modify, delete, or create any resources in your cluster.

  • 05

    How often does the AI refresh the cost data?

    The AI pulls fresh data from OpenCost every time you ask a question.
