GitHub Actions workflow stats

✨ A GitHub CLI extension to calculate the success rate and execution time of workflows and jobs.

• Calculate the success rate and execution time of workflow runs
  • Average, median, minimum, and maximum execution time of successful runs
  • Detailed each runs
    • Fetch the workflow runs and workflow runs attempts
    • Run ID, Actor, Started At, Duration(seconds), HTML URL
  • rate of success, failure, and others outcomes
• Calculate the success rate and execution time of workflow job steps
  • Average, median, minimum, and maximum execution time of successful jobs
  • Detailed each jobs
    • rate of success, failure, and others outcomes for each step
    • Detailed each steps
      • Step name, Step number, Runs count, Conclusion, Rate, Execution duration, Failure HTML URL
  • Most failed steps
  • Most time-consuming steps
• This tool can use composite action and reusable workflow.

Installation

You can install it using the gh cli extension.

gh extensions install fchimpan/gh-workflow-stats

Quick Start

If you want to get the success rate and execution time of a workflow:

$ gh workflow-stats -o $OWNER -r $REPO -f ci.yaml

If you want to get the success rate and execution time of a workflow job in JSON format:

$ gh workflow-stats jobs -o $OWNER -r $REPO -f ci.yaml --json

Usage

$ gh workflow-stats -h
Get workflow runs stats. Retrieve the success rate and execution time of workflows.

Usage:
  workflow-stats [flags]
  workflow-stats [command]

Examples:
$ gh workflow-stats --org $OWNER --repo $REPO -f ci.yaml

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  help        Help about any command
  jobs        Fetch workflow jobs stats. Retrieve the steps and jobs success rate.

Flags:
  -a, --actor string            Workflow run actor
  -A, --all                     Target all workflows in the repository. If specified, default fetches of 100 workflow runs is overridden to all workflow runs. Note the GitHub API rate limit.
  -b, --branch string           Workflow run branch. Returns workflow runs associated with a branch. Use the name of the branch of the push.
  -C, --check-suite-id int      Workflow run check suite ID
  -c, --created string          Workflow run createdAt. Returns workflow runs created within the given date-time range.
                                 For more information on the syntax, see https://docs.github.com/en/search-github/getting-started-with-searching-on-github/understanding-the-search-syntax#query-for-dates
  -e, --event string            Workflow run event. e.g. push, pull_request, pull_request_target, etc.
                                 See https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows
  -x, --exclude-pull-requests   Workflow run exclude pull requests

  -h, --help                    help for workflow-stats
  -H, --host string             GitHub host. If not specified, default is github.com. If you want to use GitHub Enterprise Server, specify your GitHub Enterprise Server host. (default "github.com")
  -i, --id int                  The ID of the workflow. You can also pass the workflow file name as a string. (default -1)
      --json                    Output as JSON
  -o, --org string              GitHub organization
  -r, --repo string             GitHub repository
  -s, --status string           Workflow run status. e.g. completed, in_progress, queued, etc.
                                 See https://docs.github.com/en/rest/reference/actions#list-workflow-runs-for-a-repository

Use "workflow-stats [command] --help" for more information about a command.

Fetch number of workflow

By default, workflow-stats and workflow-stats jobs commands will return 100 workflow runs. If you want to get all workflow runs, you can use the --all flag. However, GitHub API has a rate limit, so please combine other parameters as appropriate to reduce the number of API requests.

# Get executed at 2022-01-01 or later and actor is $ACTOR
$ gh workflow-stats -o $OWNER -r $REPO -f ci.yaml -A -c ">2024-01-01" -a $ACTOR

More details on API rate limits can be found in the GitHub API documentation.

GitHub Enterprise Server

If you want to use GitHub Enterprise Server, you can use the --host flag or set the GH_HOST environment variable. Host name is http(s)://[your-github-host]/api/v3/

$ export GH_HOST="your-github-host"
$ gh workflow-stats -o $OWNER -r $REPO -f ci.yaml
# or
$ gh workflow-stats -o $OWNER -r $REPO -f ci.yaml --host="your-github-host"

How it works

This tool retrieves workflow execution statistics using the GitHub API. For more details on the parameters, please refer to the GitHub API reference.

• Workflow runs
• Workflow jobs

Rate Limiting

GitHub imposes a primary rate limit and a secondary rate limit on all API clients.

When you reach the primary rate limit, results are calculated based on successful fetches. In the secondary rate limit, this tool handles requests in a round-tripper to avoid the rate limit. Therefore, the execution time may be longer.

Standard Output

Sample output

🏃 Total runs

Total runs is the total number of workflow runs that status is completed. It includes success, failure, and others outcomes. Others outcomes include cancelled, skipped, etc.

Total runs includes the results of attempts other than the latest. This means that for a workflow that succeeds on the third attempt, the results of the first and second workflow executions are also included in the calculation.

⏰ Workflow run execution time stats

Workflow run execution time stats is the average execution time of workflows with success conclusion and completed status.

📈 Top 3 jobs with the highest failure counts (failure runs / total runs)

Top 3 jobs with the highest failure counts is the top 3 jobs with the highest failure counts. It is not failure rate. Instead of using the success rate, the tool displays jobs based on the number of failures, as jobs with fewer executions but a high failure rate would otherwise be ranked higher.

The number of jobs displayed can be changed with a command-line argument -n.

📊 Top 3 jobs with the longest execution average duration

Top 3 jobs with the longest execution average duration is the top 3 jobs with the longest execution average duration.

The number of jobs displayed can be changed with a command-line argument -n.
