This one really was a pain in the ass for a long time.
Jenkins is great, not only for building projects, but I start the most of the ops related tasks here. All the projects have their own workspace, I can browse the previous outputs, see if a task failed or not, and I can easily share the results at the end of the task.
I had only one problem with that: the long-running tasks weren’t shown on console output until they finished. I tried to solve that, but it was only annoying, not a showstopper, so I let that go, because it didn’t look like an easy win, and I didn’t want to spend too much time on that.
But last week I created a job for online altering the database and – surprise! – pt-online-schema-change was continuously updated the console log screen, so I started to google out what is happening.
