Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Introducing Flora: Newly launched eBPF observability solution with near-zero resource overhead, for optimal performance in modern cloud-native environments
Also, have you already looked at sysdig? I don't think they're exactly tracing focused, but they've been around a long time and the times I've tried it locally it's been neat

Problem building the scap kernel module for sysdig
Seems like sysdig has some problems with newever kernels [1]. Also, the version in the repos should probably be updated (xbps: 28.0, upstream: 30.0). Maybe updating it would even solve the issue.

Systemd service sandboxing and security hardening 101
FWIU, e.g. sysdig is justified atop whichever MAC system.
In the SELinux MAC system on RHEL and Debian, in /etc/config/selinux, you have SELINUXTYPE=minimal|targeted|mls. RHEL (CentOS and Rocky Linux) and Fedora have SELINUXTYPE=targeted out-of-the-box. The compiled rulesets in /etc/selinux/targeted are generated when
With e.g gnome-system-monitor on a machine with SELINUX=permissive|enforcing, you can right-click the column header in the process table to also display the 'Security context' column that's also visible with e.g. `ps -Z`. The stopdisablingselinux video is a good SELinux tutorial.
I'm out of date on Debian/Ubuntu's policy set, which could also probably almost just be sed'ed from the current RHEL policy set.
> * SELinux is deny by default, while in systemd you're playing whack-a-mole anyway, and are expected to add directives one by one until the application stops working. Unit logs usually make it obvious if something was denied.*
DENY if not unconfined is actually the out-of-the-box `targeted` config on RHEL and Fedora. For example, Firefox and Chrome currently run as unconfined processes. While decent browsers do do their own process sandboxing, SELinux and/or AppArmor and/or 'containers' with a shared X socket file (and drop-privs and setcap and cgroups and namespaces fwtw) are advisable atop really any process sandboxing?
Given that the task is to generate a hull of rules that allow for the observed computational workload to complete with least-privileges, if you enable like every rule and log every process hitting every rung on the way down while running integration tests that approximate the workload, you should end up with enough rule violations in the log to even dumbly generate a rule/policy set without the application developer's expertise around to advise on potential access violations to allow.
From https://github.com/draios/sysdig :
> "Sysdig instruments your physical and virtual machines at the OS level by installing into the Linux kernel and capturing system calls and other OS events. Sysdig also makes it possible to create trace files for system activity, similarly to what you can do for networks with tools like tcpdump and Wireshark.
Probably also worth mentioning: "[BETA] Auditing Sysdig Platform Activities"

Does anyone here use sysdig? What are your thoughts?
I'm about to go on an interview with them I am curious if anyone here uses sysdig on an enterprise level and what your thoughts are on their product? It's totally open source and looks awesome from what I can tell so far.

Wireshark & tcpdump: A Debugging Power Couple
To begin with Wireshark, visit their official website for the download. The installation process is straightforward, but attention should be paid to the installation of command-line tools, which may require separate steps. Upon launching Wireshark, users are greeted with a selection of network interfaces as seen below. Choosing the correct interface, such as the loopback for local server debugging, is crucial for capturing relevant data.

Non-IP networking
If you're very curious as to what is really going on under the hood, I recommend you familiarize yourself with port mirroring for your switch platform of choice, and then use a laptop in promiscuous mode to capture traffic using Wireshark. Failing that, hire a network engineer to interview one of their sales engineers or architects, and have them explain it to you.

How to implement SSL/TLS pinning in Node.js
A great way to test the effectiveness of a pinning implementation is by simulating an MITM attack. Tools like Mitmproxy or Wireshack allow us to create a test environment to monitor, intercept, and proxy network requests for a test host.

Network+ Wireshark classification question
Obviously based on the question you know the answer is a Wireshark-like software and it boils down to how you classify Wireshark. My issue is that Wikipedia refers to it as a Packet Analyzer, Varonis refers to it as a Packet Sniffer, Wireshark refers to itself as a Network Protocol Analyzer, Kali documentation refers to it as a Network Sniffer, Wireshark's README refers to itself as a Network Analyzer OR Sniffer...
What are some alternatives?
perf-tools - Performance analysis tools based on Linux perf_events (aka perf) and ftrace
mitmproxy - An interactive TLS-capable intercepting HTTP proxy for penetration testers and software developers.
httpstat - curl statistics made simple
pyshark - Python wrapper for tshark, allowing python packet parsing using wireshark dissectors
