FIXEye and FIXGrep are powerful next generation FIX log analyzers. These utilities are the result of many years of experience in FIX support. These log browsers go beyond traditional parsers and are equipped with full knowledge of FIX objects and their state management.

Based on the complex search conditions specified by the user, FIXEye will generate the corresponding alerts in real time. A typical use of an alert mechanism is the acknowledgment of an order that hasn't been received for longer than X milliseconds. Another fundamentally important feature of both the FIXEye and FIXGrep tools is the ability to identify the last state of a specific order or all orders. Our guide "FIXEye, Getting Started" will take you through the host of features available in the tool.
