Figure: The Menu

User name

The menu item labelled "Menu / User name..." is intended for setting the name associated with your selection criteria and layout settings.

This item is not displayed if using HTTP-Authentication and you are not the admin user, as this implies the user associated with the preferences to be saved or loaded (you are using HTTP-Authentication if you had to provide a user name and password when visiting the MyARM web browser page initially).

Preferences

The menu item labelled "Menu / Preferences..." opens a dialog for changing your preferences:


Figure: Preference dialog "Display" tab

The tab Display specifies the time and date formatting used when displaying dates and times. The default setting is to use European settings. By clicking the checkbox "UTC" you can force displaying the time in Universal Time Coordinated (UTC).

The drop-down-box labelled "Identification" controls what is displayed under the column "Identification" in the results area. You can choose one of the following different identification formats:

  1. "Application:Transaction" for displaying the identification as a string composed by the ARM application name and ARM transaction name, separated by ":"
  2. "Transaction" for showing the ARM transaction name as identification
  3. "Transaction[:URI]" if you want to see the URI associated with the transaction as identification just after the ARM transaction name (separated by a ":")

The drop-down-box labelled "Response time" determines which granularity is used for displaying response times. You can specify "Microseconds", "Milliseconds", "Seconds", "Minutes", "Hours" or "Days".

Setting "Identification" to "Transaction[:URI]" and "Response time" to "Seconds" will display the results like this:

The tab Tree specifies the default settings to use when loading and displaying transaction trees:


Figure: Preference dialog "Tree" tab

These are the settings that you can change:

"Transaction limit"
specifies the maximum number of measurements shown in a diagram in the tree view
"Default tree depth"
is the number of levels to descend from the parent transaction when drawing the diagrams in the tree view
"Default %-Filter"
controls which measurements are shown in the diagrams in the tree view. Those with a net response time less than the value specified here are not shown
"Execution unit context name"
a textfield to enter the context property name which holds the number of execution units (for example CPU cores) used by the SpeedUp diagram to calculate the speedup of a parallel execution according to the sequential execution

More details are provided in the section documenting the tree view.

Date selection

The menu item "Menu / Date selection" controls which input is possible for setting the time interval for which an analysis is to be performed.


Figure: Date selection sub-menu

The default is "One day", which allows for specifying a single day, together with a fixed time and an interval around this time. All transactions started in this interval will be found. Setting the date selection to "Multiple days" will switch the search method to full days. You will be able to specify "Today", "Yesterday", "Last working week" etc.

About

Selecting the menu item "Menu / About MyARM ..." will open a window displaying an informational text about the MyARM (e.g. version, edition, contact address, etc).
