@aaron @faidon are you still interested in the remainder of ori's tools ("histogram" and "trends")?

trend and trends:

#!/bin/bash
log-trend() {
  sparkline=$(ls -t1 /a/mw-log/archive/"$1".log*.gz | head -30 | tac | xargs -L 1 lcz | spark)
  printf "%-30s\t%s\n" "$1" "$sparkline"
}

log-trends() {
  export -f log-trend
  ls -1 /a/mw-log/*.log             |\
    xargs -n1 -I{} basename {} .log |\
    xargs -P $(nproc) -n1 bash -c 'log-trend "$@"' _ | sort
}

Unclear to me what the histogram tool actually refers to. Maybe https://github.com/wikimedia/puppet/blob/production/modules/admin/files/home/ori/.binned/dist ? @Gilles or @Krinkle or @aaron, do you know?

I believe that is the script, yes, though I can't seem to figure out how to it to format properly (the histogram bars are the same size).
