 The History tab shows a graphic display of the Target connection activity over time. Data is shown on separate line graphs for each topic that is relevant for the selected Target. Click on the section headings to expand/collapse the graph display.

Each graph shows color coded lines indicating the events that occurred over time. A key indicating the colors used to represent various types of data is shown below each graph.

You can create an Incident to see an incident view of what happened during a specific time by selecting an area on a graph and clicking the Add Incident button. For more information about Incidents, see 

The graphs have the following functionality:

• Set the time range of the display either by selecting one of the preset time ranges or by entering a custom time range. (Default: Last 24 hr)

  Info
  One year of history is saved in the ZEN Master database even though the graphs show larger timeframes. Contact Zixi if you require more than one year of history.

  
  

• Manually refresh graph data or set the automatic refresh frequency.
• Hover over a point on the graph to show the total values for that time.
• Click and drag the cursor over a time range to zoom in on that time range.
• Double click on the graph to zoom out on the graph (i.e. expand the time range).

• Click on the title of a data element in the key to display only that element.

  Info
  ZEN Master treats all graphs as a single component so that the zoom time range set for one graph is automatically applied to all graphs on that screen. Similarly, when you hover over a point on one graph, the tool-tip values are shown for the same point in time on all of the graphs.

  
  

  Info
  The granularity of the graph depends on the zoom level. Most graphs can zoom in to a resolution of one datapoint per minute.
