Hi, Yesterday, I modified the metadata so that babeltrace can read the multiple stream files.
For this, I added the stream_id at the beginning of every stream file. e.g 0,1,.....31. https://github.com/rmeena840/rtems-tools/commit/7c6b27192e1dbdc405db7280b3f2f672ac32488b I modified the metadata by keeping in the following format in mind: <strean_id> <ns> <event> <data> <ns> <event> <data>..... https://github.com/rmeena840/rtems-tools/commit/5acaea6b5983c903ce904f17220655664b57513b The babeltrace was able to read the values from each stream files. Now, I came across trace compass examples which use one stream in metadata to read the multiple stream files. I tried this approach but the babeltrace gives me following error: [error] Stream 17 is not declared in metadata. [error] Stream index creation error. [error] Open file stream error. [warning] [Context] Cannot open_trace of format ctf at path ctf. [warning] [Context] cannot open trace "ctf" from ctf for reading. [error] Cannot open any trace for reading. [error] opening trace "ctf" for reading. [error] none of the specified trace paths could be opened. I even added packet.context in the stream but still, it reports me the same error. struct packet_context { uint64_clock_monotonic_t timestamp_begin; uint64_clock_monotonic_t timestamp_end; uint64_t content_size; uint64_t packet_size; uint64_t packet_seq_num; uint32_t events_discarded; uint32_t cpu_id; }; -- *Ravindra Kumar Meena*, B.
