dping (Distributed ping)

This is a test application based on riak_core.

What is this?

dping a.k.a distributed ping is HTTP checker application based on the riak_core.

dping can check web server availability from some nodes on different networks. For example, internal network, monitoring company and some home ISP network.

This is useful to find out a problem.

How to use

attach to the vnode and type dping(<URL>).

Below is a sample on the ring which includes 4 nodes(dping1-4).

% dev/dev1/bin/dping attach
(dping1@127.0.0.1)2> dping("http://www.google.com").
 command from 'dping1@127.0.0.1'
 dping to "http://www.google.com" recieved. node: <0.237.0> on 'dping1@127.0.0.1'
 responsed node 'dping1@127.0.0.1'
 responsed node 'dping2@127.0.0.1'
 responsed node 'dping3@127.0.0.1'
 dping to "http://www.google.com" success.
 ok

This shows HTTP GET was sent from dping1, 2, and 3.

Naming

At first, I think check only ping(ICMP echo) but I noticed HTTP is more efficient....
