Release Notes
September 2020
Welcome to Foglight for DB2 LUW
Resolved issues and enhancements
Getting started with Foglight for DB2 LUW
Foglight® for DB2 LUW utilizes a lightweight agent that provides real-time monitoring of all layers of an enterprise application (systems, networks, Internet, and databases) and captures pertinent infrastructure application usage, service, and availability level data used to continually assess the state of an DB2® LUW installation. Using this collected data, Foglight Management Server provides a multi-dimensional view of resource utilization for capacity planning, problem determination, and trend analysis, both real-time and historically.
These Release Notes cover the resolved issues, known issues, workarounds, and other important information about the 5.9.7.10 release of Foglight for DB2 LUW. Review all sections before starting the installation.
Version 5.9.7.10 contains the following new features and updates:
Note: The minimum version of Foglight Management Server for this feature is 5.9.5.
The following is a list of issues addressed and enhancements implemented in this release.
