Define yourself the timeframe of data in the database that shall be used for generating the display.
The Monitors page can be defined to operate in 2 'dynamic modes' and 1 'cumulative mode'. The dynamic modes auto-update with the most recent data without user interaction. The 'cumulative mode' is History/Trend Analysis where you can define any time interval for the actual display of the data.
- Current: Display values based on Current data values collected by SQL DM for MySQL for every specific server. Some server metrics will only be meaningful after the server has been running for a while (ie, after the server has been 'warmed-up').
- Delta: Display results based on data for the period between the last data collection and the collection before it. The result gives you a better idea of the current situation, and how much this current situation differs from the average or normal situation.
