aPing

A simple API Ping tool to feed a Swagger/OpenAPI 3.0 document file, call all paths and record time and responses, e.g. to benchmark an endpoint.

Features

• Read Swagger/OpenAPI 3.0 api definition files and call all paths
• Ping all paths in parallel workers and/or over several loops
• Pass custom headers, e.g. Authorization
• Create random integer and string parameters for urls
• Track the time and response body per request
• Output the results to console, CSV, HTML, JSON or Markdown

Latest Versions

• 0.4.0
  • Added regular expression filter option for paths
  • Added response time milliseconds threshold
• 0.3.0
  • Added average ms calculation for multiple loops
  • Added Bootstrap HTML template with sortable table
  • Added JSON output
• 0.2.0
  • Added an option to configure included query methods

Usage

For a quick start download a release, change into the directory and execute the binary with your options, e.g.:

./aping -input="calls.json" -header='{\"Authorization\": \"Bearer eyXYZ\"}' -response -base=http://localhost:8080/api -out=html -l=5 -w=5

Example progress output:

Options

Usage
  -input string
        *The path/url to the Swagger/OpenAPI 3.0 input source
  -base string
        The base url to query
  -header string
        Pass a custom header as JSON string, e.g. '{\"Authorization\": \"Bearer TOKEN\"}' (default "{}")
  -loop int
        How often to loop through all calls (default 1)
  -out string
        The output format. Options: console, csv, html, md, json (default "console")
  -response
        Include the response body in the output
  -timeout int
        The timeout in seconds per request (default 5)
  -worker int
        The amount of parallel workers to use (default 1)
  -methods string
        An array of query methods to include, e.g. '[\"GET\", \"POST\"]' (default "[\"GET\",\"POST\"]")
  -threshold int
        Only collect pings above this response threshold in milliseconds (default -1)
  -filter string
        A regular expression to filter paths. Only matches will be pinged!

Input

Reference a file input somewhere reachable by your machine. References in the OpenAPI specification can be resolved if absolute or relative to the main file.

Base

Pass a base url such as http://localhost:8080/api. If non is given the servers array of the OpenAPI specification will be presented to pick a server from.

Header

Pass custom headers to send with every request as an escaped JSON string such as '{\"Authorization\": \"Bearer eyXYZ\"}'.

The default headers are

"Accept":       "*/*"
"Connection":   "Keep-Alive"
"Content-Type": "application/json"
"User-Agent":   "aPing"

You can override these options by passing the same key.

Worker

How many parallel processes should be spawned to query your endpoints.

Ensure that your endpoint can handle multiple requests, otherwise multiple workers might run into the timeout.

Output

Define an output format. The output is written to a local aping.XYZ file, depending on your choice.

The output contains (at most):

• The pinged path
• The effective URLs (base + path)
• The query method
• The average milliseconds
• The responses

Some data is only available with their according flags, i.e. loop and response

Loop

If loop > 1 is mixed with response all responses are logged, if the path has parameters!
