Spotlight on MySQL Home Page

The Spotlight home page shows the flow of information and commands between various sub-components and the size and status of internal resources such as processes, disk files and memory structures.

Related operating system statistics are grouped together on panels that are connected by a series of graphical flows and icons. Spotlight updates these flows in real time so you can see how quickly data is moving through the system. The icons change color as Spotlight alarms are raised, upgraded, downgraded and canceled.

Tip: Hover the mouse pointer over a panel component for more information.

Spotlight on MySQL Alarms

Spotlight alarms indicate when the MySQL database exceeds acceptable performance thresholds.

Alarm Description

Buffer Pool Hit Rate Alarm

The Buffer Pool Hit Rate alarm fires when the proportion of table data that can be found in the InnoDB buffer pool drops below a specified threshold.

CPU Busy Alarm

The CPU Busy alarm occurs when the total CPU utilization of the system exceeds a threshold. The CPU may encounter a large number of requests, or you may have un-tuned SQL, which unnecessarily uses excessive amounts of CPU.

Inefficient Sort Alarm

The Inefficient Sort alarm fires when the number of temporary files created for sorts is high in comparison to the number of sorts performed.

Low Free Physical RAM Alarm

The Low Free Physical RAM alarm occurs when the server’s available RAM is low.

Query Cache Hit Rate Alarm

The Query Cache Hit Rate alarm fires when the proportion of SQL queries that can be found in the MySQL query cache drops below a specified threshold.
