[rrd-users] Threaded reachability rrd [create|update]r

[Shawn]

If it's useful to anyone I've written a threaded reachability ping rrd
updater which collects pct_loss, rrt_min, rrt_avg and rrt_max.

The ping count and number of threads are configurable via command line
among other things.

Right now you can modify a hash assignment in the script to add
addresses to monitor or you can use the
--places="<rrd_prefix>:<addr>:<label>#<rrd_prefix>:<addr>:<label>"
command line option. (':' is a field separator and '#' is the record
seperator).

Here are a couple example runs: (sorry if it line-wraps)
