Is there a simple (linux cli) tool that I can run continuously for a period of time to see if the there are any connection problems between two specific network endpoints over the wan?
One remote site is experiencing slowdowns/drops and I'm looking o figure out which side of the network is at fault.
The accepted answer recommends 'mtr'; for future reference, mtr accepts the following relevant options:
--report This option puts mtr into report mode. When in this mode, mtr will run for the number of cycles specified by the -c option, and then print statistics and exit. This mode is useful for generating statistics about network quality. Note that each running instance of mtr generates a significant amount of network traffic. Using mtr to measure the quality of your network may result in decreased network performance. --report-cycles COUNT Use this option to set the number of pings sent to determine both the machines on the network and the reliability of those machines. Each cycle lasts one second.
