The wizard has the following steps:
- Select snapshots
The telemetry comparisons compare two or more snapshot files. In this step, you select whether you want to
compare the snapshots that you have selected in the snapshot selector,
or whether all snapshot files should be compared. The default selection depends on whether you have selected
more than one snapshot in the snapshot selector.
- Probe selection
In this step, you choose for which probe the comparison should be made. If you select the "custom probe" option,
all snapshots are analyzed to find out which custom probe are present in all snapshots.
- Telemetry group
In this step, you choose for which telemetry group the comparison should be made. Probes can publish one or more
telemetry groups with multiple measurements each.
- Comparison type
Each snapshot file contributes one value to the comparison graph. That value can be the
- current value
This is the value when the snapshot was saved, i.e. the rightmost point in the
telemetry view and the value that is displayed next to the legend entries there.
- maximum value
This is the maximum value during the entire time that the telemetry view
was recording data. The maximum value is evaluated separately for each snapshot file.
- value at a bookmark
In JProfiler, you can set bookmarks for specific points in time. In addition,
there are automatic bookmarks for recording events. If all compared snapshots contain a bookmark with the same name,
you can compare values at those times. If you choose this option you have to select a bookmark from
the combo box below. Only bookmarks that are contained in all snapshots are displayed.
- Compared measurements
In this step you select which of the measurements from the selected
telemetry group that should be compared. You can select any combination of measurements.
