The issue that I see is that at least the `lttng_statedump_file_descriptor` events no longer have a pid field which the older lttng-analyses code assumes is present. To find this out When running the manual recording steps, could you add the following command before running `lttng start`: ``` lttng add-context --kernel --type=pid ``` To pinpoint the source of the error, I used the `--debug` parameter for `lttng-analyses` as follows: ``` # lttng-schedtop --debug lttng-traces/lttng-analysis-27010-20231031-182735/ Checking the trace for lost events... Traceback (most recent call last): ] ETA: --:--:-- File "/usr/local/lib/python3.7/dist-packages/lttnganalyses/cli/command.py", line 73, in _run_step fn() File "/usr/local/lib/python3.7/dist-packages/lttnganalyses/cli/command.py", line 365, in _run_analysis self._automaton.process_event(event) File "/usr/local/lib/python3.7/dist-packages/lttnganalyses/linuxautomaton/automaton.py", line 81, in process_event sp.process_event(ev) File "/usr/local/lib/python3.7/dist-packages/lttnganalyses/linuxautomaton/sp.py", line 33, in process_event self._cbs[name](ev) File "/usr/local/lib/python3.7/dist-packages/lttnganalyses/linuxautomaton/statedump.py", line 91, in _process_lttng_statedump_file_descriptor pid = event['pid'] File "/usr/local/lib/python3.7/dist-packages/babeltrace/babeltrace.py", line 912, in __getitem__ raise KeyError(field_name) KeyError: 'pid' Error: Cannot run analysis: 'pid' ``` thanks, kienan On 2023-10-31 07:44, 姜涛 Tao(AD) via lttng-dev wrote: > Hi everyone, I use lttng-analysis tools to parse the trace files but get > error as below: > > I try two methods to catch the trace data: “automatic” using > lttng-analysis-record and “manual” using lttng > create/enable-event/start/stop/destroy, but always get the errors when > using lttng-analysis tools(0.6.0 and 0.6.1 version). > > I load the lttng modules(2.12.14 version) successfully: > > 文本 描述已自动生成 > > The environment is as below: Ubuntu20.04 aarch64, kernel version: > 5.10.120 rt patch. > > Any help will be appreciated!
