we're using Nagios and SmokePing to monitor our systems. In case of problems between our office and a hosting facility we can see risen round trip times and packet losses but have no clue what's the cause of the problem.
I have seen that there's SmokeTrace (http://oss.oetiker.ch/smokeping/doc/smoketrace.en.html) that allows trace routes from within SmokePing.
At best there was a tool that monitors routes and records them for later reference constantly.
Does anyboy know about such a tool/plugin, preferred open source?
I would like to have access to a traceroute result or something like that at a later point in time when I get aware that there was a problem.
