Ah, yes, yet another clash of the titans: Flame Graphs, Tree Maps, and #Sunbursts battling it out in a death match no one asked for, but everyone pretends to care about 🤷‍♂️. With more buzzwords than a Silicon Valley startup's pitch deck, this 2017 throwback is as relevant as a floppy disk in a cloud computing world 🌩️💾.

Off-CPU Analysis - by Brendan Gregg:

- On-CPU: where threads are spending time running on-CPU
- Off-CPU: where time is spent waiting while blocked on I/O, locks, timers, paging/swapping, etc.

Have been generating those CPU flame graphs on bare metal, so being able to use them in k8s seems to be pretty useful to me. https://www.percona.com/blog/kubernetes-observability-code-profiling-with-flame-graphs/ #flamegraphs #k8s #kubernetes

The best software is the one, where you can't decide if something is a cool or a terribly ugly idea.

➤ GNOME的Sysprof添加了FlameGraphs以更好地可視化輸出
✤ https://www.phoronix.com/news/GNOME-Sysprof-FlameGraphs
GNOME的Sysprof添加了FlameGraphs以更好地可視化系統分析工具的呼叫圖數據。
+ 這是一個很好的改進，讓人們更好地瞭解系統分析工具的呼叫圖數據。
+ 這將有助於GNOME的使用者更好地瞭解他們的系統，並更好地優化它們。

Brendan Gregg does some great talks. Just watched this one on #eBPF and #flamegraphs: https://www.youtube.com/watch?v=HKQR7wVapgk

Could understand about half but very interesting nonetheless

@richardstartin@fosstodon.org Perhaps it’s just me but I find #flamegraphs less useful as the profile grows in size and dominating effects weaken. Then it’s back to #JMC tabular data (usually itable stubs!) which I combine with a little #LogCompilation parser to get the JIT’s view on what’s happening.

The example bt(5)/btrace(8) scripts are now installed in #OpenBSD -current (missed with 7.1):

• kprofile .bt (save kernel stackframes & produce flamegraphs)
• runqlat .bt (measure the latency of the scheduler runqueues).

You can generate #flamegraphs with Brendan Gregg's FlameGraph script. :flan_thumbs:​
