Using Observer in financial firms
Chapter 12: GigaStor in Financial Firms 251
Outside of the GigaStor Control Panel, these other areas may be valuable for you
when you are analyzing FIX transactions:
♦
Decode and Analysis in Observer—Allows you to decode and analyze
the raw FIX information and presents it in an easy to read format. In the
Decode and Analysis tab you can use filters and do post-capture analysis
on specific FIX transactions that have issues.
♦
Application Transaction Analysis in Observer—Examines all transactions
related to FIX even those beyond layer 4 into the application layer.
Information about the transactions of applications for each request
and the type of request are tracked. View a graph of response time
and application error conditions or request and response results. ATA
performs in-depth application analysis of each request or type of request
by examining important information within the payload. This information
typically involves massive amounts of data often best viewed in graphical
format to more easily spot trends or patterns.
♦
Baseline and trending reports in Observer or Observer Reporting Server
—Using Application Transaction Analysis you can create reports on all FIX
statistics for capacity planning. If you have numerous probes from which
you want FIX transactions aggregated and analyzed, then use Observer
Reporting Server (sold separately).
Configuring a FIX profile
Observer uses profiles to analyze FIX data. Default profiles are in three main
categories: pre-trade, trade, and post-trade. Within each category, there are
numerous variants that allow you to focus on a specific trade type, such as "Pre-
trade: Quote Negotiation." You can use the settings described here to edit, create,
import, or export a FIX profile.

FIX Profile
Lists the name of the current profile. The current profile is the
rest of the dialog window, including the General Settings and
the Type/Message.
Edit
Use this button to rename, add a new, or delete a profile. If you
have numerous GigaStor probes where you want to use the
same FIX analysis options, modify or create the profiles on one
system, export them, and import them into the other GigaStor
probes.
Import
Use this button to import FIX profiles that was created and
exported from another Observer.
Export
Use this button to export a FIX profile.
General Settings
Maximum tracked
requests
Lists the maximum number of requests to be tracked during
the time frame selected in the Detail Chart. The default is
1000 requests. Typically, 1000 requests should be sufficient
to provide the information you seek. If it is not, you may
increase or decrease it. By increasing the amount of requests,
the amount of system resources needed to analyze the requests
is also increased, which means the analysis will take longer to
complete.
