The team at Boundary were kind enough to demo their new network and flow monitoring and visualisation solution to me. It’s pretty cool albeit it has a fairly limited feature set so far. Their future directions show some interesting promise though especially around the potential ability to visualise networks and services.
If you’re lucky enough to be involved in the beta (or if you make use of the product after launch) then I’ve developed a Puppet module to deploy Boundary probes. It installs the required software and has a custom type and provider to deploy Boundary meter probes.
