How to visually spot and analyze slow MongoDB operations
Do you ever wonder why your MongoDB databases seem to be much slower than expected? Do you experience periodical hot spots and want to know the culprit(s)? Do you want to know which database operations are the most expensive and the ones most meaningful to improve?
In this talk you will quickly understand the limits of MongoDB's built-in database profiler, especially in sharded environments. I will present an open source tool we developed to solve these issues. We created a tool that collects, stores and helps to visually analyze slow MongoDB operations. By using the tool you will get a better picture of your MongoDB clusters without the need of a deeper MongoDB expertise. The tool runs database commands simultaneously against a multitude of databases or mongod's and with just a few clicks you can easily intervene and spot performance issues.
