1# AKS Cost Analysis Add-on
2 
3Enable namespace-level cost visibility using the built-in AKS cost monitoring add-on.
4 
5## Check Status
6 
7```bash
8# Check if add-on is enabled
9az aks show \
10  --name "<cluster-name>" --resource-group "<resource-group>" \
11  --query "addonProfiles.costAnalysis" -o json
12 
13# Check cluster tier (add-on requires Standard or Premium)
14az aks show \
15  --name "<cluster-name>" --resource-group "<resource-group>" \
16  --query "{tier:sku.tier, name:name}" -o table
17```
18 
19## Enable Add-on
20 
21```bash
22# Requires Standard or Premium tier
23az aks update \
24  --name "<cluster-name>" --resource-group "<resource-group>" \
25  --enable-cost-analysis
26```
27 
28## If Cluster is Free Tier
29 
30Warn user that upgrading from Free to Standard introduces an ongoing cluster management fee. Use the official AKS pricing page or this skill’s pricing validation step to confirm the current cost with the user and obtain explicit approval before proceeding. After user approval:
31 
32```bash
33az aks update \
34  --name "<cluster-name>" --resource-group "<resource-group>" \
35  --tier standard
36 
37az aks update \
38  --name "<cluster-name>" --resource-group "<resource-group>" \
39  --enable-cost-analysis
40```
41 
42## After Enabling
43 
44Namespace-level cost data is available in:
45- Azure Portal: AKS cluster -> Cost Analysis blade
46- Azure Cost Management: filter by cluster resource ID + `kubernetes namespace` dimension
47 
48> Risk: Low for enabling the add-on. Upgrading tier (Free -> Standard) has a cost — always confirm with user first.
