Comments

I tried using LTTng analysis for tracing and started with the given samples from the manual:
I use ubuntu on a VM and installed all necessary packages. I used the given example to collect the trace data as described within the manual:
lttng-analyses-record
After I recorded some events I tried analysing them:
sudo lttng-cputop lttng-analysis-17045-20200818-174021
When executing this command I will get tons of warnings and an error at the end:
I also tried the same command on the sample trace provided in the manual and it works flawless.
Im really not sure what I am doing wrong here, I also used a clean VM and reinstalled all neccessary packages without success.
