Event Tracing — The Linux Kernel documentation
https://www.kernel.org/doc/html/latest/trace/events.html
The trace event subsystem provides an in-kernel API allowing modules or other kernel code to generate user-defined ‘synthetic’ events at will, which can be used to either augment the existing trace stream and/or signal that a particular important state has occurred.

Linux Kernel events tracing When working on a Linux system, it can be convenient to use the kernel events tracing mechanism, (described in details in Documentation/trace/events.txt in the Linux kernel sources). We will only focus on a very simple use case here. Listing possible event traces

An introduction to Linux activity/event trackers
https://www.howtoforge.com/tutorial/linux-activity-and-event-tracker/
GNOME Tracker. Most modern GNU/Linux distributions use some kind of a software service that tracks the user activities and events. These events can be anything, from the opening of a document file, to the chat conversation. This isn't happening for the purpose to monitor the user and sell this usage data information to 3rd parties, but to help users enjoy a more user-friendly …
Event Tracing — The Linux Kernel documentation
https://www.kernel.org/doc/html/v4.17/trace/events.html
The events which are available for tracing can be found in the file /sys/kernel/debug/tracing/available_events. To enable a particular event, such as ‘sched_wakeup’, simply echo it to /sys/kernel/debug/tracing/set_event. For example: # echo sched_wakeup >> /sys/kernel/debug/tracing/set_event.

user_events: User-based Event Tracing — The Linux …
https://docs.kernel.org/trace/user_events.html
Overview ¶. User based trace events allow user processes to create events and trace data that can be viewed via existing tools, such as ftrace and perf. To enable this feature, build your kernel with CONFIG_USER_EVENTS=y. Programs can view status of the events via /sys/kernel/debug/tracing/user_events_status and can both register and write data out via …
Practical Linux tracing ( Part 2/X ) : Profiling vs Event ...
https://medium.com/coccoc-engineering-blog/practical-linux-tracing-part-2-x-profiling-vs-event-tracing-89f76113e0fd
Event tracing works in pretty much the same way. By using probe ( kprobe / uprobe ) or tracepoints ( Linux kernel tracepoints or User Defined Static Tracepoints ) , we can get notified when a ...
Dynamic Event Tracing in Linux Kernel
https://events.static.linuxfound.org/slides/lfcs2010_hiramatsu.pdf
Kprobe-Tracer. Dynamic event tracer. Based on kprobes (kprobe and kretprobe) Add/delete new events on the fly. trace-event/perf-event compatible. –Enable/disable, filter and record by ftrace and perf tools. Put a new trace-event with register/memory arguments. Function entry (symbol) + offset / function return.
