When you create Custom Database Metrics in AppDynamics, you first thought is to create a new row for each metric, but if you have a lot to report on this can become messy. Not only that but in the metric view you will have a very long list of reports to go through. Therefore when we had the consultant down at work, we was shown how to group collections of metrics in one query, which then shows in the metric view in a sub folder. This tactic, we could not find anywhere on the internet, so I thought I would share this very handle insight for AppDynamics.
When I told a college I was going to write some unit tests for CSS they went crazy, and I do see why, however I think it can be valuable in the right way. I would like to describe to you why I think doing unit tests on CSS can be worth your time as a developer and also beneficial to the project.
