You'll probably receive alarms for 'tcp listen drops'. This is likely bot-related (sending INVALID packets) and NOT due to your application dropping legitimate packets. There is a good discussion on how to identify the source of the problem and how to mitigate or resolve it [https://github.com/firehol/netdata/issues/3234 Issue #3234] [https://github.com/firehol/netdata/issues/3826 Issue #3826] TLDR; increase the threshold to 1 (<code>/etc/netdata/health.d/tcp_listen.conf</code>) so you don't get bogus alerts.
