    parse(opts[:log], opts[:key]).join("\n")
end

puts app

This fails for "transactions" because the sample value is not a list

WORKS:
{sample,connect,
[0.593017578125,0.47900390625,0.509033203125,0.512939453125,
0.427978515625,0.509033203125,0.573974609375,0.62890625,0.505859375,
60.676025390625]}

FAILS:
{sample,tr_foo,2.0390625}
