DESCRIPTION
Join DevOps Evangelist, Jason Hand, for a discussion on ChatOps and the movement to deploy, measure, and mitigate from a chat client. With more and more teams implementing methods to trigger commands from within their favorite chat clients, the time it takes to perform specific and repetitive tasks has been dramatically reduced. In providing a real-time command history to others, we can share knowledge and learn from each other faster than ever before.TRANSCRIPT

Jason: Hey Dan … did you see that spike in CPU usage on Prod1.. ~ 3 minutes ago?
Dan: No. Let me check. brb
Dan: Shit. Yeah, I see it. Looks ok now. I think :-/
Jason: Think we should let Mike know? He might want to dig in to it later.
Dan: Yeah, I’ll take a screenshot and email it to him.
Jason: Would anyone else need to know about it?

Jason: Hey Dan. My code is ready to push when you are.
Dan: Cool. I’ll commit it to the latest branch here in a minute.
Jason: Great. Also, we should probably sit down with Nick (new guy) and show him how to do that soon.
Dan: Yeah. Once I get some time, I’ll schedule something. :/
Jason: There’s probably a bunch more stuff to show him too, but I’m not sure I even know all of the steps for everything.
Dan: We’ve got a wiki for most things, but not everything. I’ll see what I can find and email him.
