The LTTng scope beta project was an attempt at doing a significant UX redesign of Trace Compass, starting from a use-cases/user workflow perspective. We currently don't have the resources/funding/staff to work on this project further, so it has not progressed for a while. You should look at the Trace Compass and VSCode trace extension projects instead, which have a lot more activity: https://tracecompass.org https://github.com/eclipse-cdt-cloud/vscode-trace-extension The LTTng analyses beta project is a set of python scripts to analyze LTTng traces. Our original intent with that project was that EfficiOS would fund the work to create those analyses as prototypes in Python, and eventually customers would fund the rather large amount of work required to go from a prototype (slow scripts) to a production quality project (faster C++ implementation, generic state tracking module). Unfortunately, this never materialized, so this beta project has been on the back burner as well. In the recent years we have focused our efforts on the Babeltrace 2 project and on CTF2 (Common Trace Format version 2). Feel free to have a look at Trace Compass and VSCode trace extension, and please let us know if LTTng scope and LTTng analyses fill a gap that is not covered by those other tools.

We are going to go with Trace Compass. Could I hit you with one more question? I've been unable to find an answer on the web. When I build lttng-modules using the sources and instructions from here<https://github.com/lttng/lttng-modules/blob/master/README.md#kernel-built-in-support>, it fails because it cannot sign the kernel modules with keys. During the "make modules_install" phase, it gives these messages for each module: At main.c:160: - SSL error:02001002:system library:fopen:No such file or directory: crypto/bio/bss_file.c:69 - SSL error:2006D080:BIO routines:BIO_new_file:no such file: crypto/bio/bss_file.c:76 sign-file: certs/signing_key.pem: No such file or directory INSTALL /root/lttng-modules-master/src/lib/lttng-lib-ring-buffer.ko Subsequently, the modules fail to load with an error: modprobe: ERROR: could not insert 'lttng_ring_buffer_client_discard': Required key not available I'm am installing on a RHEL8 system. Is this because RHEL8 is not supported as an official Enterprise release? Have the keys and/or their locations changed for RHEL8?

Here is the Redhat documentation on the subject [1].
