XpoSearch returns a graph that shows the distribution of events over time. You can choose how to display the graph and what to show in the graph. The graph has drilldown functionality, enabling you to zoom into any timeslot, and perform the same search on that timeslot. It also enables you to click on a bar or line graph to see the source of events and drill down to see the exact events in any log. You can also view the previous or next timeslot.    

Defining the Graph

XpoSearch enables you to define what your graph looks like, as well as its contents, using the icons on the Graph Toolbar.

Defining Graph Display

You have the option of displaying your graph as a bar graph (the default) or a line graph. In the bar graph, a bar appears at each point in time where events were found to match your search query. The height of each bar represents the number of events that occurred at the specific time. A bar does not appear at times when no events matching your search query occurred. A line graph shows how the number of events matching the search query changed from one point in time to the next.

To display your graph as a bar graph:

• In the Graph Toolbar, click Image Removed.

To display your graph as a line graph:

• In the Graph Toolbar, click Image Removed.

Defining Graph Contents

You have the option of displaying your graph in a split view or a summary view. In the split view, the number of bars or lines in a timeslot is according to the number of logs that were the source of events in that timeslot; each bar or line represents the number of events for each log source of vents. In the summary view, a single bar or line represents all events from all log sources.

To display your graph in split view:

• In the Graph Toolbar, click Image Removed.

To display your graph in summary view:

• In the Graph Toolbar, click Image Removed.

Viewing Distribution of Results in Logs

You can click any bar in your graph to see the number of matching events that were produced by each log. You can then click any log to open the log viewer under the XpoLog tab. There, you can see a detailed listing of each matching event in the log. This information includes the date and time of the event, thread ID, thread, and message. 

Zooming In/Out of a Timeslot

You can zoom into any timeslot in your graph, so that you can see a more detailed breakdown of events over a smaller period of time. For example, a search executed for a time period of seven days shows the distribution of events that match the search criteria, per day. You can then zoom into any timeslot (day) to see the distribution of events during that day, and you can zoom in further to see the distribution of events in a specific hour on that day. At any point, you can zoom out repeatedly until you reach the graph resulting from the time period that you selected for the search query.  

To zoom into a timeslot:

• In the graph, in the timeslot which you want to zoom into, click the zoom in icon Image Removed.
  The zoomed-in timeslot is subdivided into smaller timeslots. The Image Removedbutton appears, enabling you to zoom  out to the previous display. The time period of the search is automatically changed to Custom.
  You can repeatedly click the  zoom in icon Image Removed to see a more detailed distribution of the events.     

To zoom out of a timeslot:

• In the graph, click the Image Removed button.
  You can repeatedly click theImage Removedbutton until the graph is displayed for the time period that you selected for the search query. At this point, the Image Removed button will no longer appear.

Viewing the Previous/Next Timeslot

You can display a graphical representation of the number of events that meet the search criteria in the previous or next timeslot, directly from the graph.

To display the previous timeslot:

• Below the graph, on the left, click the Image Removed icon.

To display the next timeslot:

• Below the graph, on the right, click the Image Removed icon.

Analyzing Search Result Events

The execution of a Simple Search generates all events that match the search query, up to the maximum allowed by the system. A summary panel is displayed above and below the list of events, enabling you to view the summary of the search and to navigate to any page in the search. You can view the analytics of any event, and view the event in a log viewer. You also have a choice of expanding all events to see their stack traces, and disabling analytics of events (which is normally enabled).
