Sysdig
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.

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I'm out of date on Debian/Ubuntu's policy set, which could also probably almost just be sed'ed from the current RHEL policy set.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.
