MaxCompute Migration Service (MMS) provides a Migration Observation tab that shows real-time migration progress and hourly and daily throughput per data source. Use this data to identify when migration load is highest and reschedule jobs to avoid peak business hours.
Prerequisites
Before you begin, ensure that you have access to the MaxCompute console.
View migration progress and speed
Log on to the MaxCompute console and select a region in the top-left corner.MaxCompute console
In the left navigation pane, choose Data Transfer > Migration Service.
On the Migration Service page, click the Migration Observation tab. The tab shows two sections: Migration progress and Migration speed.
Migration progress
The Migration progress section shows real-time status for each data source:
Metric | Description |
Migrated data volume | The amount of data successfully transferred |
Pending data volume | The amount of data yet to be transferred |
Migrated partitions | The number of partitions successfully transferred |
Pending partitions | The number of partitions yet to be transferred |
Completed tasks | The number of migration tasks that finished successfully |
Running tasks | The number of migration tasks currently in progress |
Pending tasks | The number of migration tasks queued and not yet started |
Migration speed
The Migration speed section shows data throughput at two levels of granularity:
Daily total: The total volume of data migrated across all data sources on a given day.
Hourly per data source: The migration volume for each data source, broken down by hour.
Use this information to evaluate the daily migration speed and plan your migration schedule to avoid overlapping with peak business hours.
