Example polling API client daemon in core PHP, stashed here for later...
This code is part of a ping plotting application I poked around at writing. My goal was to implement a minimalistic client/server API using nothing but core PHP, without any external dependencies. Once the bare essentials were done, and I had a functional client "daemon" and a functional server-side ingester, I moved on and never got around to building a web interface.
Everything here works, but nothing is complete. I've logged millions of pings
with the client (pinger.php) running on a variety of Linux, Windows, Mac, and
FreeBSD systems. But there's no web interface to speak of, just display.php,
which can generate a graph of ping data. It uses JpGraph, not included here.
To run the client:
/usr/bin/php /usr/local/etc/pinghampton/pinger.php > /dev/null 2>&1 &
On the server, a cron job should be set to run every few minutes and distill the submitted raw ping data into the format used by the grapher:
*/3 * * * * /usr/bin/mysql --defaults-file=/home/cronsql/.mysql_password < /path/to/production-push.sql
