I'm 100% anecdotally sure many of the problems we're running into are due to intermittent network failures, but since we're using an Openstack IaaS provider I don't have access to logs at that level. I've got TCP failures and retransmits in my metrics pipeline, but I'm looking for something more compelling. What would be perfect is a small agent app that can constantly monitor links and track failures explicitly, because what I expect is that we're getting frequent jitters rather than hard link failures. Basically I just want to be able to prove if this IaaS is too brittle for production. Ideas?
