This is a plugin for Logstash.
It is fully free and fully open source. The license is Apache 2.0, meaning you are pretty much free to use it however you want in whatever way.
This plugin will open up a http keep-alive connection to any http server and periodically execute GET requests. The response body will be added to the message field of the logstash event.
This plugin also adds a X-Logstash-Avg-Queue-Secs header to every GET request. This indicates the average amount of "wait time" an event is waiting to be added to logstash's intenal bounded/blocking input queue. The server could use this value to determine how many events to send to logstash based on the throughput/wait time.
{logstash_dir}/bin/plugin install logstash-input-httpclient

All contributions are welcome: ideas, patches, documentation, bug reports, complaints, and even something you drew up on a napkin.
Programming is not a required skill. Whatever you've seen about open source and maintainers or community members saying "send patches or die" - you will not see that here.
It is more important to the community that you are able to contribute.
For more information about contributing, see the CONTRIBUTING file.
