Perfo Logger scenario viewer

The perfo Logger scenario viewer allows to view the graph of a perfo Logger engine serialized scenario.

Interface

The viewer has:

• A menu which allows to select the log file to show in the logger, or to save its content
• A panel which shows the events which were recorder in the log

For each invocation, the viewer shows:

• An icon showing that the event is an invocation
• The time of the invocation (ie the time of the invocation as seen in output of the module which performed the invocation)
• An id for the invocation (this is a number which increments for each invocation)
• The service complete name (name and namespace if it has a namespace or only the name if the service has no namespace)
• The module which emitted this invocation

For each invocation to another framework instance through the network, the viewer shows:

• An icon showing that the event is an invocation
• The time of the socket emission
• The service complete name (name and namespace if it has a namespace or only the name if the service has no namespace)

For each notification, the viewer shows:

• An icon showing that the event is a notification
• The time of the notification (ie the time of the notification as seen in input of the module which was notified)
• The corresponding id of the invocation which is at the origin of this notification
• The service complete name (name and namespace if it has a namespace or only the name if the service has no namespace)
• The module which emitted the corresponding invocation
• The module which received the notification

For each notification from another framework instance through the network, the viewer shows:

• An icon showing that the event is a notification
• The time of the socket reception
• The service complete name (name and namespace if it has a namespace or only the name if the service has no namespace)

Menu

A Search button allows to search events in the log, possibly filtered by their service or module:

Actions on the events panel

Right clicking on a row will shows an invocation will present the following menu:

• "Select Time From": Select the time beginning by this event
• "Select Time To": Select the time ending with this event^[1]
  Only available after selecting "Select Time From" before
  . A popup window appear showing the time between the two selected time events. For example:
  
  
• "Select Sequence From": Select the sequence beginning by this event
• "Select Sequence To": Select the sequence ending with this event^[2]
  Only available after selecting "Select Sequence From" before
• "Select All Sequence": Select the whole sequence of events

Right clicking on a row will shows a notification will present the following menu:

• "Select Time From": Select the time beginning by this event
• "Select Time To": Select the time ending with this event^[1]
  Only available after selecting "Select Time From" before
  . A popup windows appear showing the time between the two selected time events
• "Select Sequence From": Select the sequence beginning by this event
• "Select Sequence To": Select the sequence ending with this event^[2]
  Only available after selecting "Select Sequence From" before
• "Select All Sequence": Select the whole sequence of events

Creating a sequence diagram

After having performed "Select Sequence To" or "Select All Sequence", the corresponding events are highlighted in green:

A popup window allows to filter what will be kept in the sequence:

• It is possible to filter which services will be shown in the diagram
• It is possible to filter which modules will be shown in the diagram

After clicking on "Yes", a diagram appear showing the associated sequence diagram:

Sequence diagrams with network communication

Invocations and notifications to and from another framework instance through the network are also shown in the sequance diagrams:

Working with a sequence diagram

The sequence diagram can be saved in png or svg. It can also be cropped to show a part of the sequence. Validating the crop will synchronize the logger view to the cropped diagram.
