Database Autonomy Service (DAS) allows you to globally customize monitoring dashboards. If enterprise users want to manage multiple instances, they can customize multi-instance monitoring dashboards to correlate, compare, and view multiple instances and metrics for daily O&M.

Prerequisites

Monitoring metrics

DAS monitoring dashboards support the following metrics. In this example, MySQL is selected.

Parameter Description
tps Formula: (Com_commit + Com_rollback)/Uptime
qps Formula: Number of questions/Uptime
active_session The number of active sessions.
delete_ps The average number of DELETE statements executed per second.
insert_ps The average number of INSERT statements executed per second.
replace_ps The average number of REPLACE statements executed per second.
update_ps The average number of UPDATE statements executed per second.
select_ps The average number of SELECT statements executed per second.
bytes_received The average number of bytes received from all clients per second.
bytes_sent The average number of bytes sent to all clients per second.
innodb_bp_hit The read cache hit ratio of the InnoDB buffer pool. Formula: (Innodb_buffer_pool_read_requests - Innodb_buffer_pool_reads)/Innodb_buffer_pool_read_requests × 100%
innodb_bp_dirty_pct The dirty page ratio of the InnoDB buffer pool. Formula: Innodb_buffer_pool_pages_dirty/Innodb_buffer_pool_pages_data × 100%
innodb_bp_usage_pct The usage of the InnoDB buffer pool. Formula: Innodb_buffer_pool_pages_data/(Innodb_buffer_pool_pages_data + innodb_buffer_pool_pages_free) × 100%
innodb_data_written The average number of bytes written by InnoDB per second.
innodb_data_read The average number of bytes read by InnoDB per second.
innodb_rows_deleted The average number of rows deleted by InnoDB per second.
innodb_rows_read The average number of rows read by InnoDB per second.
innodb_rows_inserted The average number of rows inserted by InnoDB per second.
innodb_rows_updated The average number of rows updated by InnoDB per second.
Note You can view the description of each metric by clicking the icon in the console.
