Predicting Application Problems with Database Metrics

As data practitioners, we want to get ahead of any problems that might come up and share those insights with others on our team. In this episode, Edward Pollack gives us a few scenarios we might consider as we attempt to prevent application issues. These techniques also go into the security space and could help prevent data loss. As we collect this information and make it available to others, we can also demonstrate the ROI we provide to the organization.

3 Takeaways

  1. IO trends can be a way to spot hacking/suspicious activity
  2. Capturing the before and after metrics help show ROI—which can increase your value
  3. More success will come when you can present what is needed versus just sharing a bunch of data. Putting a little presentation on the data can go a long way.
