Collects ping times between a list of servers and displays in a chart.
How to use
Install this on each server you want to add to the pool to be measured. Copy
config.js and update the list of servers as appropriate. I've found it works quite a bit better
if you enter the servers' IP addresses to avoid doing a DNS lookup each time.
Start the scripts on all the servers as background processes, such as with this command:
nohup node pulse.js & They will begin collecting timing information from each server in the list,
and will send that information to each other server as well.
You can then visit http://example.com:50505/stats on any one of the servers to see its report.
