Script to log network hop errors

I need a Linux bash script which will log hop problems when a target IP cannot be reached. Here is a scenario we might experience when we are testing newly installed [login to view URL] is assuming a multi hop failure as an example. -Hop 6 goes down but then comes back online -Hop 5 goes down but then comes back online -Hop 7 goes down but then comes back online Once the target can be reached again, the outage is over so the script ends by spitting out it's log. The log must contain only the most relevant data, stripping everything but the following; timestamp - outage start DATE/TIME - HOP# - IP/Name timestamp - 6 [login to view URL] (reached hop 5 so we know hop 6 was unreachable) timestamp - 5 [login to view URL] (reached hop 4 so we know hop 6 was unreachable) timestamp - 7 [login to view URL] (reached hop 6 so we know hop 6 was unreachable) timestamp - end of outage NOTE: This must also work on openwrt routers which have limited capabilities so communicating about the methods used will be important.
