Viewing Historical SQL Records of DWS

All the historical queries in the current cluster will be displayed. If you do not want to see historical system queries, you can toggle on Hide System Queries.

  • Historical queries can be viewed only in clusters of version 8.1.2 and later.
  • The historical query monitoring function is disabled by default. To enable it, choose Monitoring Settings. On the Monitoring Collection page, enable Historical Query Monitoring. For details, see Monitoring Collection. Exercise caution when enabling this as it may generate a large amount of data.

Going to the Historical Query Page

  1. Log in to the DWS console.
  2. Choose Dedicated Clusters > Clusters and locate the cluster to be monitored.
  3. In the Operation column of the target cluster, click Monitoring Panel.
  4. In the navigation pane on the left, choose Monitoring > History.

Checking Historical Queries

In the History area, you can browse all historical query information based on the specified time period. You can click the setting button in the upper right corner of the list to select the metrics to be displayed in the list. For details about the metrics, see Table 1.
