Sloth VS bcc

That said, after I learned about how to use lsof, I found this little free app called =Sloth (and its github page ), which is just a nice native Mac app serving as a GUI for lsof. It'll let you know exactly which process to quit or kill so your drive can eject happily.

Random fact; this website is created and maintained by Sveinbjörn Þórðarson who also made Platypus (https://github.com/sveinbjornt/Platypus) and Sloth (https://github.com/sveinbjornt/Sloth) — software that Mac nerds might be familiar with.

Sveinbjörn is a ball of energy that just radiates positives for human society.

git clone https://github.com/sveinbjornt/Sloth.git

a very nice, open source, app that provides similar functionality but also shows open files is Sloth (https://sveinbjorn.org/sloth).

Sloth will do what you need.

But wait, there's more! Enter the BCC toolkit and library, your trusty sidekick in simplifying the arcane art of writing eBPF applications. With BCC by your side, you'll be wielding eBPF like a seasoned pro in no time.

Nice - I normally use [bash-readline](https://github.com/iovisor/bcc/blob/master/tools/bashreadlin...) when coworking/co-inhabiting a server or training someone.

One of the big wins is not so much “build and run your own stuff” but there are very nice low-cost (in terms of compute) performance utilities built on eBPF

There are so many utilities in that list; there’s a diagram midway down the readme which tries to help show their uses. bcc-tools should be available in any distro.

Also, Brendan Gregg does a ton of performance stuff that is worth knowing about if you check out his other work. Not eBPF only. Flame graphs are useful.

In this article, we'll build a basic version of an HTTPS sniffer, inspired by bcc-sslsniff.py, but we'll use Rust and Aya. We're going to demonstrate the capabilities of uprobes by employing uprobe and uretprobe along with familiar maps like PerCpuArray, HashMap, and PerEventArray. This will be a straightforward example to help us explore how uprobes function.

As xpd program I am using the BCC example xdp_redirect_map.py in skb mode as my NIC does not support native mode, attaching the program to veth2 and a dummy function to veth3
