How to Heroku-style app monitoring in Dokku?

Question

I really like Heroku's app monitoring. But I don't have it in my Dokku PaaS. I want to see my apps and plugins CPU, RAM, disk load, network IO, ...

Is there a way that I can easily collect and visualize these stats with Dokku? Is there an out-of-the-box solution for this or I need to manually set up the Grafana and it's integration to each app and plugin?

I'm afraid there's no straightforward way to do this.

What we're doing in our project is we have a cron job that collects the stats of individual Dokku apps directly from Docker every couple minutes:

docker stats --no-stream --format "{{.Container}},{{.Name}},{{.CPUPerc}},{{.MemUsage}},{{.MemPerc}},{{.NetIO}},{{.BlockIO}}" > docker-stats.csv

And the data from the CSV file is then loaded directly into our custom admin UI (using a JavaScript lib called Tabulator):

It's hacky but it does the job.
