Finding missed opportunities in lnd.log:
zgrep "insufficient bandwidth to route htlc" ~/.lnd/logs/bitcoin/mainnet/lnd.log* | grep "ChannelLink" | cut -d' ' -f5,11 | awk 'BEGIN { FS=OFS=SUBSEP=" "}{arr[$1]+=$2 }END {for (i in arr) print i,arr[i]}' | sort -n -t' ' -k2 -r

Oh, commands to get this data:
$ ./bitcoin-cli getpeerinfo | grep subver | sort | uniq -c | sort -n
$ tail -n5000000 ~/.bitcoin/debug.log | sed -n 's/.*receive version message: //p;' | sed 's/ version [0-9]*, blocks=.*//' | sort | uniq -c | sort -n
(2nd requires -debug=net)

quick jq command to compute the total amt of satoshis your lnd node has routed in the past month:
lncli fwdinghistory --start_time="-1M" --max_events=5000 | jq '[.forwarding_events[].amt_out | tonumber] | add'
my node has really been glowing up this year: 1.22 BTC ($70k) MTD
