It’s pretty rare but sometimes it can be useful to capture statsd metrics at the source.
Here’s an example that uses tshark to capture some dogstatsd metrics on the fly.
$ tshark -f "udp port 8125" -i any -T fields -e data | xxd -p -r
Running as user "root" and group "root". This could be dangerous.
