Our team(of 20-25) is considering exploring ChatOps for a few use cases around incident management and server monitoring. In your experience, what are the pros and cons of doing ChatOps? What tools did you use(Hubot, Lita, Err, YellowAnt, Posh etc.)? What were the problems you were trying to solve and did ChatOps help?
We use it for deployment, building, getting status information from various environments, a few escalated customer support tasks, as well as security and monitoring alerts. Security and monitoring alerts above a certain severity level also get delivered other ways.
We're running an old version of Hubot that talks to Slack. It crashes frequently so we have a script that restarts it. It's ugly, but it works. I'm planning an overhaul.
I can't really think of any cons, other than people constantly asking for more plugins/scripts.
One thing that bears mentioning is that our team is Slack-heavy so this is a natural cultural fit for us.
