Scout APM
Scout APM - Leading-edge performance monitoring starting at $39/month. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

Developer tools can be magic. Instead, they collect dust
Debuggers are very specific tools, and I've never really liked them.
Basically, you get a tiny view of what your code is doing, and have to slowly build a mental model of what's going on through time. I have found that prints and code reading (in a good IDE which is able to track variable references!) are often enough, and usually faster,for the kind of software I write.
Now, things are getting better: mozilla's RR is a game changer(reverse debugging on actual, large projects ), and more recently, pernosco (built on RR but very close to science-fiction) has at long last made me like debuggers again.

Ask HN: What are some “10x” softiware product innovations you have experienced?
The rr debugger [1]. I _desperately_ missed it after switching to a mac laptop -- to the point that I now have an older linux system which exists primarily to run rr.
I've _heard_ that Pernosco [2] (partly built on rr, AFAIK) is even more revolutionary, but haven't yet tried it myself.

It can be made to work in everything except VirtualBox, see: https://github.com/rr-debugger/rr/wiki/Building-And-Installing#virtual-machine-guests

Looking for More Debugger
I need to throw a million +1's at the `rr` suggestion. it's really great. It's a shame that it doesn't work on ARM processors, but there are good fundamental reasons why it doesn't (it's basically impossible iirc[0])
In terms of U.I's I found `gdb-many-windows` to be the nicest i found. While I hate almost everything about the platform, I have to concede that visual studio's debugging integration is actually really good. The only thing I found annoying was that I needed to use Visual Studio for it! (emacs on windows could be annoying enough that I got used to it eventually, but still preferred by linux environment, this is back when working on a cross platform C++ project if that much weren't already clear).

45,000+ lines of Rust code later: An update on the Record & Debug Tool (rd)
BTW there is initial Linux ARM64 support for rr (BTW rd has not ported over ARM64 support yet). Please see rr 5.4.0 release announcement https://github.com/rr-debugger/rr/releases/tag/5.4.0
The best course of action would be to file an issue in the rr issue tracker https://github.com/rr-debugger/rr for your particular IDE -- the rr folks are extremely responsive and should be able to provide answers/pointers.

Postmortem of outage on 20th December
not sure if rr can be used here to record and replay the bug, so to help debug it.
