In group_run_stats, convert these fields: * io_kb (bytes transferred) * agg (aggregate average bandwidth) * min_bw * max_bw from tracking either KiB or KB depending on kb_base to simply tracking bytes. Rename io_kb to iobytes to match this new meaning. This will simplify computing quantities and bandwidth rates with both IEC binary and SI decimal unit prefixes (e.g., GiB/s and GB/s) in future patches. --- client.c | 2 +- server.c | 2 +- stat.c | 23 +++++++++-------------- stat.h | 2 +- 4 files changed, 12 insertions(+), 17 deletions(-) diff --git a/client.c b/client.c index 48d4c52..1b4d3d7 100644 --- a/client.c +++ b/client.c @@ -972,7 +972,7 @@ static void convert_gs(struct group_run_stats *dst, struct group_run_stats *src) dst->min_run[i] = le64_to_cpu(src->min_run[i]); dst->max_bw[i] = le64_to_cpu(src->max_bw[i]); dst->min_bw[i] = le64_to_cpu(src->min_bw[i]); - dst->io_kb[i] = le64_to_cpu(src->io_kb[i]); + dst->iobytes[i] = le64_to_cpu(src->iobytes[i]); dst->agg[i] = le64_to_cpu(src->agg[i]); } diff --git a/server.c b/server.c index 2e05415..b7ebd63 100644 --- a/server.c +++ b/server.c @@ -1444,7 +1444,7 @@ static void convert_gs(struct group_run_stats *dst, struct group_run_stats *src) dst->min_run[i] = cpu_to_le64(src->min_run[i]); dst->max_bw[i] = cpu_to_le64(src->max_bw[i]); dst->min_bw[i] = cpu_to_le64(src->min_bw[i]); - dst->io_kb[i] = cpu_to_le64(src->io_kb[i]); + dst->iobytes[i] = cpu_to_le64(src->iobytes[i]); dst->agg[i] = cpu_to_le64(src->agg[i]); } diff --git a/stat.c b/stat.c index ebc5c78..f014e60 100644 --- a/stat.c +++ b/stat.c @@ -291,10 +291,10 @@ void show_group_stats(struct group_run_stats *rs, struct buf_output *out) if (!rs->max_run[i]) continue; - p1 = num2str(rs->io_kb[i], 6, rs->kb_base, i2p, 8); - p2 = num2str(rs->agg[i], 6, rs->kb_base, i2p, rs->unit_base); - p3 = num2str(rs->min_bw[i], 6, rs->kb_base, i2p, rs->unit_base); - p4 = num2str(rs->max_bw[i], 6, rs->kb_base, i2p, rs->unit_base); + p1 = num2str(rs->iobytes[i], 6, 1, i2p, 8); + p2 = num2str(rs->agg[i], 6, 1, i2p, rs->unit_base); + p3 = num2str(rs->min_bw[i], 6, 1, i2p, rs->unit_base); + p4 = num2str(rs->max_bw[i], 6, 1, i2p, rs->unit_base); log_buf(out, "%s: io=%s, aggrb=%s/s, minb=%s/s, maxb=%s/s," " mint=%llumsec, maxt=%llumsec\n", @@ -1418,7 +1418,7 @@ void sum_group_stats(struct group_run_stats *dst, struct group_run_stats *src) if (dst->min_bw[i] && dst->min_bw[i] > src->min_bw[i]) dst->min_bw[i] = src->min_bw[i]; - dst->io_kb[i] += src->io_kb[i]; + dst->iobytes[i] += src->iobytes[i]; dst->agg[i] += src->agg[i]; } @@ -1696,19 +1696,14 @@ void __show_run_stats(void) rs->max_run[j] = ts->runtime[j]; bw = 0; - if (ts->runtime[j]) { - unsigned long runt = ts->runtime[j]; - unsigned long long kb; - - kb = ts->io_bytes[j] / rs->kb_base; - bw = kb * 1000 / runt; - } + if (ts->runtime[j]) + bw = ts->io_bytes[j] * 1000 / ts->runtime[j]; if (bw < rs->min_bw[j]) rs->min_bw[j] = bw; if (bw > rs->max_bw[j]) rs->max_bw[j] = bw; - rs->io_kb[j] += ts->io_bytes[j] / rs->kb_base; + rs->iobytes[j] += ts->io_bytes[j]; } } @@ -1719,7 +1714,7 @@ void __show_run_stats(void) for (ddir = 0; ddir < DDIR_RWDIR_CNT; ddir++) { if (rs->max_run[ddir]) - rs->agg[ddir] = (rs->io_kb[ddir] * 1000) / + rs->agg[ddir] = (rs->iobytes[ddir] * 1000) / rs->max_run[ddir]; } } diff --git a/stat.h b/stat.h index 22083da..aa4ad80 100644 --- a/stat.h +++ b/stat.h @@ -7,7 +7,7 @@ struct group_run_stats { uint64_t max_run[DDIR_RWDIR_CNT], min_run[DDIR_RWDIR_CNT]; uint64_t max_bw[DDIR_RWDIR_CNT], min_bw[DDIR_RWDIR_CNT]; - uint64_t io_kb[DDIR_RWDIR_CNT]; + uint64_t iobytes[DDIR_RWDIR_CNT]; uint64_t agg[DDIR_RWDIR_CNT]; uint32_t kb_base; uint32_t unit_base; -- 2.9.3 -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
