The Dashboard is a page displaying a graphical view of the server parameters and metrics that in most situations will give you a quick overview of the server load and performance. SQL DM for MySQL ships with a default dashboard called "Performance metrics" which includes the metrics:
- Cache misses
- Database Throughputs
- Disk IO
- CPU usage
How is the refresh interval defined?
Every graph displays related metrics using different colors. In the Charts interface the X-axis timestamps are not printed, and the time interval between each reflects the server-specific setting for the sample interval. By default, the chart displays the last one-hour timeframe. If no data is available for a period because MONyog(SQL DM for MySQL) service was stopped, two empty sample points display in the grid no matter how long time has passed.
Just click the drop down menu containing the Dashboard names, and select the Add New Dashboard option. This opens the page where you can give a suitable dashboard name and decide which charts to enable for your dashboard.
Dahboard settings can be changed from the dashboard page itself. These are local (browser specific) settings that are stored in a cookie.
- The size of the Chart is configurable, you can stretch/reduce the charts size.
