Resource Trend Graph​

  • Multi-line chart visualizing resource count trends by type
  • Time range toggle: 30 days / 90 days
  • Resource type toggles to select which resources to display

Core Resources (Displayed by Default)​

Cost Impact Estimation​

Estimates monthly cost impact based on resource count changes:

  • RDS Instances: $200/month (estimated)
  • ElastiCache Clusters: $150/month
  • EKS Nodes: $100/month
  • NAT Gateways: $45/month
  • EC2 Instances: $80/month
  • Weight factors applied for other resources

How to Use​

  1. Check Trends: Review resource count change patterns in the graph
  2. Change Time Range: Toggle between 30d/90d for analysis period
  3. Select Resources: Use toggle buttons to show only resources of interest
  4. Analyze Table: Review detailed numbers and change rates
  5. Cost Impact: Check the cost estimation section at the bottom
Snapshot-Based Data

Resource Inventory automatically saves snapshots when the dashboard loads. History data accumulates without additional API queries, so there is no performance impact.

Usage Tips​

Tracking Resource Growth​

Check resources highlighted in orange (increase) in the 7d Change or 30d Change columns. Unexpected increases may be causing cost spikes.

Security Resource Monitoring​

Pay attention to changes in these resources:

  • Public S3 Buckets: Increase may indicate data exposure risk
  • Open Security Groups: Increase may indicate security vulnerabilities
  • Unencrypted EBS: Compliance issues

Interpreting Cost Impact​

In the Cost Impact Estimation section:

  • Positive (+): Expected cost increase
  • Negative (-): Expected cost decrease

Actual costs may vary depending on instance types, usage, etc.

Data Retention

Snapshot data is stored in the data/inventory/ directory. Data older than 90 days is excluded from analysis but files are retained.

AI Analysis Tips​

Example questions for AI Assistant:

  • "Analyze which resources increased the most over the last 30 days"
  • "If this resource growth trend continues, how much will the monthly cost be?"
  • "Summarize security-related resource changes"
  • "Recommend items that need resource cleanup"
