Chapter 7. Zoom reports
This chapter describes how to generate zoom reports. Zoom reports allow the user to focus on specific
traffic aspects within a selected time period in the past.
Zoom reports are generated from stored flow files. These files must not be deleted but they may be
compressed. For more information, see section 4.2.
A Zoom report is a perspective on historical flows that the system has stored in regular or compressed
flow files. The Zoom report is configured like a site. Additionally, a Zoom report has a start and end
time period. The result is a snapshot that contains fixed and not updated data. In other words the
snapshot is not dynamically updated when the system receives new flows. The report is accessible
using an Analyzer-like interface and also as a PDF.
Configuring a Zoom report is similar to configuring a site. This is intentional because the system that
is running a Zoom report analyses the received flows in the same way as a site. The Zoom report
facility allows a user to create the equivalent of a site to feed flows through. The result is a Zoom
report, which matches a similarly-configured site.
Zoom reports differ from a site definition only in terms of the time domain. A Zoom report is
configured for a particular time period - the longer the period, the less the resolution. The Tivoli
Netcool Performance Flow Analyzer picks the finest of the existing resolutions that accounts for about
800 buckets. For example, selecting a report time range of two hours will result in Tivoli Netcool
Performance Flow Analyzer choosing the hour period resolution of 10 seconds. Two hours is 2 X 3600
seconds or 720 X 10-second buckets. For more information, see section 3.3.
7.1 Zoom report list page
To access the Zoom reports control page click the Zoom reports link on the top of the window. The
system displays the list of previously configured reports and a link called New Zoom report that
allows a user to create a fresh Zoom report configuration.
The list of Zoom reports contains information and links for each of the pre-existing report definitions.
There are columns for the name, status, data availability, edit-lock and processing progress. To the
right are links named open, details, clone, delete and abort. These links are active or not depending
on the report’s status.
The status field contains either open indicating that the report has been viewed by a user who is still
logged on or closed where no logged on user has viewed it. The data field indicates if data is present
in the Zoom report’s database that is the flow files have been analysed. Editable indicates whether or
not a user can change the configuration of the Zoom report. This shows yes until the report has
started running, and then it changes to no. The progress field shows the stage in its life that the Zoom
report is at that time.
The open link allows a user to view the results of a Zoom report as a snapshot using the Analyzer
page. This option is only present when a report has been run. The details link allows the user to view
the details of a report configuration and fine-grained status information. The user may also edit the
configuration if the report has not already been run. The clone allows the user to copy an existing
definition under a different name. The delete link provides a means by which the user can delete the
report result and definition. The abort link allows the user to stop a report processing.
