How to use goaccess with heroku rails app

Question

I want to generate goaccess dashboard result from heroku logs of rails application, As I checked there is no production.rb file in heroku

Format of logs in heroku is

2020-07-16T17:18:54.972063+00:00 app[web.1]: I, [2020-07-16T17:18:54.971939 #10]  INFO -- : [2712edd9-bca1-4d23-9cfd-399e6dedfbdc] Started GET "/api/v1/articles" for 18.225.35.172 at 2020-07-16 17:18:54 +0000

I tried installing goaccess on my heroku server , but I am not able to do that, and I am not able to get log file also. I want response time for each request in goaccess dashboard. Anyone has idea about this ???How I can use goaccess + rails + heroku together

Answer 1

Try this:

cat ./production.log | grep 'Started GET' | goaccess --log-format='I, "%^" "%r" %^ %h %^ %d %t %^' --date-format=%F --time-format=%T

Note: it will work only for line like:

2020-07-16T17:18:54.972063+00:00 app[web.1]: I, [2020-07-16T17:18:54.971939 #10]  INFO -- : [2712edd9-bca1-4d23-9cfd-399e6dedfbdc] Started GET "/api/v1/articles" for 18.225.35.172 at 2020-07-16 17:18:54 +0000

other lines were ignored by grep, which were:
