poing (pronounced poe-ing) is a text mode multi-host ICMP ping program. It displays ongoing host statuses as colorful leftward-scrolling strip charts. This lets you see hosts' recent health at a glance.

POE::Component::Client::Ping was adapted from the code first written in poing.

This opens up a whole new world of user interfacery. Pop-up windows, adding and removing hosts on the fly, asynchronous update rates, and other fun stuff.

Fletch wants the ability to collaps all the hosts under a group. One way to represent a collapsed group would be to base the display on the average ping response time for all hosts underneath it.

Fletch adds: Here's an idea of what groups might look like (or at least what I'm thinking of). Groups are prefixed with a + or - to show the collapsed state, group members are indented apropriately. If only a single member of a group is down, * is shown rather than - (which would indicate the whole group is unreachable). Of course if things move to Curses then this could get much fancier (groups open in their own window perhaps).

Log events (up/down) to an RDBMS via DBI.

Execute some user specified code when something changes state, such as sending email or running a program.

MRTG makes pretty graphs of things over time. It would be an ideal way to represent ping histories, but it would not be as sexy as the scrolling numbers.
