We are having intermittent issues with our internet connection in a community house of nine people. It seems to cut out for short intervals so I am looking for an app to test connectivity at regular intervals and log it. For example to ping a host on the internet every minute or so and log the results. What I want is to log when the connection is down and for how long over a period of time. This is not an enterprise issue so I am looking for a free app or script to accomplish this. Thanks

You can run a simple ping command to accomplish this:

ping -i 60 domain.com > ouput.txt

where 60 is the time between pings. To limit the total count of pings use :

ping -i 60 -c 50 domain.com > ouput.txt

where 50 is the number (count) of pings.

There are many more options to read about on the man page of ping. To access it use:

man ping

If you want more in-depth statistics on all traffic of one machine I recommend to use an application such as wireshark. It is open-source and free.

Wireshark can give you exact statistics on each packet of data sent and/or received by your computer. So if you only want to see if general connectivity is available I would consider this a little much. It can also be hard to figure out what to do with all this output from wireshark.

PS. some suggestions to ping (these are very reliable and fast but don't overdo it or they might ban your IP):

1.1.1.1     (cloudflare DNS)
8.8.8.8     (google DNS)
google.com
