Hi, I am trying to get some statistics via the Python API but fail to run the equivalent of "ceph df detail". One the command line I get: # ceph -f json df |jq .pools[0] { "name": "rbd", "id": 1, "stats": { "stored": 27410520278, "objects": 6781, "kb_used": 80382849, "bytes_used": 82312036566, "percent_used": 0.1416085809469223, "max_avail": 166317473792 } } # ceph -f json df detail |jq .pools[0] { "name": "rbd", "id": 1, "stats": { "stored": 27410520278, "objects": 6781, "kb_used": 80382849, "bytes_used": 82312036566, "percent_used": 0.1416085809469223, "max_avail": 166317473792, "quota_objects": 0, "quota_bytes": 0, "dirty": 6781, "rd": 309130743, "rd_bytes": 327278814208, "wr": 155492443, "wr_bytes": 155528225792, "compress_bytes_used": 0, "compress_under_bytes": 0, "stored_raw": 82231558358, "avail_raw": 498952444191 } } In Python I just get an error: # python Python 2.7.16 (default, Oct 10 2019, 22:02:15) [GCC 8.3.0] on linux2 Type "help", "copyright", "credits" or "license" for more information.

Anything I can do to get the output of "ceph df detail" via Python API? I would like to have the stats fields "rd", "wr", "rd_bytes" and "wr_bytes" per pool.
