Reading time ~4 minutes Diagnosing high memory usage can be tricky, here is the second part of how I found what was hogging to much memory in our system. In the previous post I’ve wrote how to create a memory dump and how many possibilities of catching just the right moment for it ProcDump has. When trying to analyze memory leaks, or high memory usage (not necessary meaning a leak) we have a few ways to approach it: Attach a debugger There are many problems with this approach, to name a fe...

In today’s post, I’ll describe what kind of interfaces have been defined in the Sentry project, and how you can take advantage of this knowledge, e.g. in order to create the custom metrics. I’ve tried to keep these interfaces as simple as possible, yet some of them require an explanation, mostly due to the fact, that even though the library itself is rather simple to use (I want to believe that it’s also what you think), it does not mean that the main methods when being executed, will return for example,...
