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?
Dan: Prob. I’ll cc the DevOps team so everyone knows
Old methods
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 Fme, 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.
