find_underused_resource_classes
Identifies underutilized CircleCI resource classes by analyzing CPU/RAM usage data from a CSV file. Helps optimize resource allocation by flagging jobs with usage below a specified threshold (default 40%).
Instructions
Analyzes a CircleCI usage data CSV file to find jobs/resource classes with average or max CPU/RAM usage below a given threshold (default 40%).
This helps identify underused resource classes that may be oversized for their workload.
Required parameter:
- csvFilePath: Path to the usage data CSV file (string). IMPORTANT: This must be an absolute path. If you are given a relative path, you must resolve it to an absolute path before calling this tool.
Optional parameter:
- threshold: Usage percentage threshold (number, default 40)
The tool expects the CSV to have columns: job_name, resource_class, median_cpu_utilization_pct, max_cpu_utilization_pct, median_ram_utilization_pct, max_ram_utilization_pct (case-insensitive). These required columns are a subset of the columns in the CircleCI usage API output and the tool will work with the full set of columns from the usage API CSV.
It returns a summary report listing all jobs/resource classes where any of these metrics is below the threshold.
