Following are definitions of the different options available when creating your
custom query.
Data Table
Select which type of network activity data to query. The correct data table to
use depends on the nature of the report.
l End-System Details - Hourly — End-system data collected every hour. Used when
data for a specific client or server is needed, or when the information requested is
highly specific, for example top applications used by Android devices in the London
site.
l Application Data - Hourly — Application data collected every hour. Used for higher
level information, such as top applications during an hour.
l Application Data - High-Rate — Application data collected at a higher rate (every
five minutes). Used for a more detailed picture of how traffic changes over time.
l Application Telemetry - Hourly — Application Telemetry flow data collected every
hour.
Display Format
Select the display format for the report: Grid, Chart Over Time, Word Cloud,
Tree Map, or Bubble Map.
Target
Network traffic information is collected on objects in your network called
targets. Some targets are physical, such as clients and servers, and some are
logical, such as applications. Select the type of target that you want
information about. Available targets vary depending on the selected data
table. If you want information on a specific target, specify that target in the
Search Criteria options.
l Applications — An application in ExtremeAnalytics is identified through layer 7
analysis of network traffic. For example, an application can be identified as
Facebook.
