[]()

 The `disk_write_speed_aggregate_node` table provides aggregated information per node about the speed of disk writes during LCP, backup, and restore operations.

 The `disk_write_speed_aggregate_node` table contains the following columns:

* `node_id`

   Node ID of this node

* `backup_lcp_speed_last_sec`

   Number of bytes written to disk by backup and LCP processes in the last second

* `redo_speed_last_sec`

   Number of bytes written to REDO log in the last second

* `backup_lcp_speed_last_10sec`

   Number of bytes written to disk by backup and LCP processes per second, averaged over the last 10 seconds

* `redo_speed_last_10sec`

   Number of bytes written to REDO log per second, averaged over the last 10 seconds

* `backup_lcp_speed_last_60sec`

   Number of bytes written to disk by backup and LCP processes per second, averaged over the last 60 seconds

* `redo_speed_last_60sec`

   Number of bytes written to disk by backup and LCP processes per second, averaged over the last 60 seconds
