ntopConf 2019 - The network is a (great) signal

We need a stable network. With microservices even more than ever because internally our services are speaking between each other as never before.
A lot of the tools like Wireshark, ntop (the current one) designed to monitor networks are awkward to me. Because I am a developer, not an expert about the network. That's it. The problem is: nobody called the support team to notify that packet loss is too high, they call when the software we develop doesn't work. The network is one of the important signals to look at when something doesn't work but we need better tools. I am trying to make network folks and developers new friends!
