So you built your decentralized Application. But then? Of course, you need to monitor it. Because always manage the money at risk and that includes proper monitoring.
There are a few resources out there to monitor decentralized applications. This blog post is a summary of links I found during my own research.
There is, as far as I know, still not one-fits-all analytics and monitoring solution out there. But there are many open-source solutions built on top of existing tools.
This page should be a summary of those tools, nothing else.
