log_to_trace

A python script to process OSD logs, extract scrubber states (for each scrub session performed), and create Jaeger-formatted spans in a json output file

Using the script:

python3 log_to_trace.py ceph-osd*log --out all_scrub_states.json

Options:

• --debug / -d : Enable debug logging
• --fixed : Use deterministic sequential IDs (trace and span IDs will be "1", "2", ...) — useful for reproducible debugging and testing

Notes:

• The input files can be gzipped.
• The --out filename is optional.
• Intermediate files are created and not removed (intentionally).

Here is how the traces created might look in a Jaeger viewer:
