new PHP daemon in Go
▪ Version 5.0 in released over a year ago included a new Go-based daemon
▪ Daemon was re-architected to allow for better performance, easier cross-platform compatibility, and overall maintenance simplicity
▪ Developers loved writing Go (vs. C)
First Go agent(s)
▪ Dev teams <3 Go.▪ Build an agent to make their Go service
acceptable in production.▪ These new agents and plugins become future
products in some cases.▪ We had at least 3 engineers try writing a
lightweight Go agent.

Whatever happened to that HHVM agent?
▪ HHVM promising early start
▪ Radically faster performance than PHP5+
▪ Wordpress, Drupal, others adopting
▪ But HHVM was massive reworking of PHP internals, and thus broke our PHP agent in some fundamental places
▪ And eventually… PHP7 launched! With similar performance gains!
▪ Building in support for PHP7 was much easier
How engineers typically engage with customers
▪ our forums▪ requests made via our account teams▪ support tickets▪ user interviews and ride-alongs▪ meetups and conferences▪ open-source and community events▪ Github
