Recently, I've been looking for a way to compare the visitor numbers to an application I run to the numbers reported in Google Analytics. Our target audience are technical people who are likely blocking trackers, and I wanted to see what kind of impact that was having on our statistics compared to the numbers shown by raw access logs.
Previously I've set up an ELK stack to ingest access logs and filter/aggregate them, but for a short term comparison it wasn't worth the investment. Thankfully, people like logz.io provide hosted ELK stacks for use. I wanted to use logz.io thanks to their excellent DevRel team - go team!
Searching around I found that there is a logz.io Heroku addon, but that starts at $150/month which is more that I'd like for some ad-hoc analysis. Looking at their pricing page I saw that there is a community plan for up to 3GB of logs per day (we're nowhere near that).
The TL;DR is this:
herokudrain that points to the listener. Make sure to use
httpsand point to port
heroku drains:add "https://listener.logz.io:8081?token=<TOKEN>" -a "<HEROKU_APP_NAME>"
