Looking for something that is opensource and preferably PHP + Java since that is what everything else on my website uses.
You would think it would be easy to embed something in your website that gives people ping times from their PC to your servers but you would be wrong. Apparently ICMP and Java/php don't get along. The alternative seems to be a seudo ping where you test response time to http or an image file or something on your server. I could live with that if it wasn't too complicated. However, there doesn't seem to be anything that does that either. At least nothing approaching an organized opensource project. There are responses to questions about this on stackoverflow where people post snippets of code that maybe is a start but that's about it.
Just to clarify. This is not something like just-ping.com where it pings from static IP servers to the IP you provide. It is also not something like nodeping that pings between one fixed point and another. It is something that shows up on my website that initiates something similar to ping between the visitors computer and static IP's I provide. Instead of them having to open a command line on their PC and typing ping xx.xx.xx.xx where xx.xx.xx.xx is an IP of one of my hosting servers.
I have searched all over and can't seem to find anything which is surprising. I would have thought there would be enough interest in something like this that someone would have posted something on github by now.
