charset="utf-8" From: Trieu Huynh MigrationStats had all-required QAPI fields, so partially populating info->ram on the destination would force display of source-only metrics (dirty-sync-count, precopy-bytes, etc.) as misleading zeros. Make those source-only fields optional with '*' in the QAPI schema. Update populate_ram_info() to set them via has_* setters so source output is unchanged. As per schema's changes, fill_destination_migration_info() can now populate info->ram for the COMPLETED case with the fields that are meaningful on the receive side: * total, remaining, page-size (RAM layout) * transferred, normal, normal-bytes (bytes/pages received) * duplicate (zero pages received) * mbps (throughput: transferred*8 /time_ms/1000) * pages-per-second (total pages / duration in seconds) Others optional fields (dirty-sync-count, precopy-bytes, downtime-bytes, postcopy-bytes, multifd-bytes, postcopy-requests, dirty-sync-missed-zero-copy, dirty-pages-rate) are left unset and are absent from the destination output. On dst, {"execute":"query-migrate"} * As-is: { "return": { "status": "completed" } * To-be: { "return": { "status": "completed", "total-time": 94, "ram": { "total": 554508288, "pages-per-second": 1440234, "page-size": 4096, "remaining": 0, "mbps": 97.955404255319152, "transferred": 1150976, "duplicate": 135101, "normal-bytes": 1150976, "normal": 281 } } } Signed-off-by: Trieu Huynh --- migration/migration.c | 35 +++++++++++++++++++++++++++++++++++ qapi/migration.json | 14 +++++++------- 2 files changed, 42 insertions(+), 7 deletions(-) diff --git a/migration/migration.c b/migration/migration.c index 17c9a8b344..925d29890d 100644 --- a/migration/migration.c +++ b/migration/migration.c @@ -1063,17 +1063,24 @@ static void populate_ram_info(MigrationInfo *info, = MigrationState *s) info->ram->normal =3D qatomic_read(&mig_stats.normal_pages); info->ram->normal_bytes =3D info->ram->normal * page_size; info->ram->mbps =3D s->mbps; + info->ram->has_dirty_sync_count =3D true; info->ram->dirty_sync_count =3D qatomic_read(&mig_stats.dirty_sync_count); + info->ram->has_dirty_sync_missed_zero_copy =3D true; info->ram->dirty_sync_missed_zero_copy =3D qatomic_read(&mig_stats.dirty_sync_missed_zero_copy); + info->ram->has_postcopy_requests =3D true; info->ram->postcopy_requests =3D qatomic_read(&mig_stats.postcopy_requests); info->ram->page_size =3D page_size; + info->ram->has_multifd_bytes =3D true; info->ram->multifd_bytes =3D qatomic_read(&mig_stats.multifd_bytes); info->ram->pages_per_second =3D s->pages_per_second; + info->ram->has_precopy_bytes =3D true; info->ram->precopy_bytes =3D qatomic_read(&mig_stats.precopy_bytes); + info->ram->has_downtime_bytes =3D true; info->ram->downtime_bytes =3D qatomic_read(&mig_stats.downtime_bytes); + info->ram->has_postcopy_bytes =3D true; info->ram->postcopy_bytes =3D qatomic_read(&mig_stats.postcopy_bytes); =20 if (migrate_xbzrle()) { @@ -1094,6 +1101,7 @@ static void populate_ram_info(MigrationInfo *info, Mi= grationState *s) =20 if (s->state !=3D MIGRATION_STATUS_COMPLETED) { info->ram->remaining =3D ram_bytes_remaining(); + info->ram->has_dirty_pages_rate =3D true; info->ram->dirty_pages_rate =3D qatomic_read(&mig_stats.dirty_pages_rate); } @@ -1209,6 +1217,33 @@ static void fill_destination_migration_info(Migratio= nInfo *info) case MIGRATION_STATUS_COMPLETED: info->has_status =3D true; fill_destination_postcopy_migration_info(info); + if (mis->total_time > 0) { + info->has_total_time =3D true; + info->total_time =3D mis->total_time; + } + { + size_t page_size =3D qemu_target_page_size(); + uint64_t normal =3D mis->received_normal_pages; + uint64_t zero =3D mis->received_zero_pages; + uint64_t xbzrle =3D mis->received_xbzrle_pages; + + info->ram =3D g_malloc0(sizeof(*info->ram)); + info->ram->total =3D ram_bytes_total(); + info->ram->remaining =3D 0; + info->ram->normal =3D normal + xbzrle; + info->ram->normal_bytes =3D (normal + xbzrle) * page_size; + info->ram->duplicate =3D zero; + info->ram->transferred =3D (normal + xbzrle) * page_size; + info->ram->page_size =3D page_size; + + if (info->has_total_time) { + info->ram->mbps =3D info->ram->transferred * 8.0 + / info->total_time / 1000.0; + info->ram->pages_per_second =3D (normal + xbzrle + zero) + * 1000.0 / info->total_time; + } + /* source-only optional omitted from output */ + } break; default: return; diff --git a/qapi/migration.json b/qapi/migration.json index 7134d4ce47..a695d04a22 100644 --- a/qapi/migration.json +++ b/qapi/migration.json @@ -68,13 +68,13 @@ 'data': {'transferred': 'int', 'remaining': 'int', 'total': 'int' , 'duplicate': 'int', 'normal': 'int', - 'normal-bytes': 'int', 'dirty-pages-rate': 'int', - 'mbps': 'number', 'dirty-sync-count': 'int', - 'postcopy-requests': 'int', 'page-size': 'int', - 'multifd-bytes': 'uint64', 'pages-per-second': 'uint64', - 'precopy-bytes': 'uint64', 'downtime-bytes': 'uint64', - 'postcopy-bytes': 'uint64', - 'dirty-sync-missed-zero-copy': 'uint64' } } + 'normal-bytes': 'int', '*dirty-pages-rate': 'int', + 'mbps': 'number', '*dirty-sync-count': 'int', + '*postcopy-requests': 'int', 'page-size': 'int', + '*multifd-bytes': 'uint64', 'pages-per-second': 'uint64', + '*precopy-bytes': 'uint64', '*downtime-bytes': 'uint64', + '*postcopy-bytes': 'uint64', + '*dirty-sync-missed-zero-copy': 'uint64' } } =20 ## # @XBZRLECacheStats: --=20 2.43.0
