Activity Plot
Figure: Memento Application – GUI Mode – Activity Plot Area

The Activity Plot area of the Memento GUI gives an idea of the recent activity of the message logging.
Horizontal Axis
The horizontal axis of the Activity Plot represents the time.
The axis has a fixed scale with major divisions of 1 minute and minor divisions of 2.5 seconds. The major divisions are labeled with the Memento time value expressed in minutes.
The activity plot shows the most recent time window: the rightmost end of the time scale is the actual time.
Vertical Axis
The vertical axis of the Activity Plot represents the number of messages per second that are effectively logged into the Memento Ring Buffer.
The axis is a logarithmic scale covering five decades:
- The first horizontal grid line is at 10 events per second
- The second horizontal grid line is at 100 events per second
- …
Trace Dots
The trace is composed of trace dots. A new trace dot is produced every ***TBD*** second.
- The green color means that the highest severity level of the logged messages is lower than
warning
. - The orange color means that the highest severity level of the logged messages is
warning
. - The red color means that the highest severity level of the logged messages is greater than
warning
.
Activity Monitoring Control

The activity plot area can be clicked to plot messages chronologically close to that point in time. This can be convenient to investigate about errors appearing in red in the activity plot area.
