New in this release
Resolved issues and enhancements
Upgrade and compatibility
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 126.96.36.199 release of Foglight for DB2 LUW. Review all sections before starting the installation.
Version 188.8.131.52 contains the following new features and updates:
This 184.108.40.206 release of Foglight for DB2 LUW does not include any resolved issues.
The following is a list of issues known to exist at the time of this release.
The Management Server 5.7.1 stops responding when clicking charts on the Tablespaces dashboard.
Workaround: Upgrade the Management Server to 5.7.5 or later.
|DB2FOG-67||DB agents need be re-upgraded after upgrading the Foglight Management Server.
Workaround: Make sure to wait for more than 10 minutes between upgrade of the Foglight Management Server and Foglight for DB2 LUW.
|GVFOG-37||The Databases dashboard does not appear after user upgrades the Foglight for DB2 LUW to 220.127.116.11 using SPM installer.|
|GVFOG-60||The "Error executing script" error shows in the server log, if user clicks any tab or component on the Global View.|
|DDB-5387||For DB2 version 9.7 and above, the following metrics are not available due to DB2 limitations: AGENT_USR_CPU_TIME_MS, AGENT_SYS_CPU_TIME_MS, LAST_RESET.|
|DDB-5376||For DB2 version 9.7 and 10.1, some statistics information about db2 background processes is not collected due to DB2 limitation|
The DB2 installer does not support foreign languages on Windows
Once the agent was activated, the following errors may be occurred:
|DDB-3669||The Foglight for DB2 LUW 18.104.22.168 Upgrade Wizard does
not support the upgrade of external agents if the Agent Manager is not
version 5.6.2 or later.
Workaround: Upgrade to Foglight Management Server 5.6.4 or later.
|DDB-2860||An Agent Manager that is installed on a Windows fail-over cluster as a service that runs on the active node cannot monitor databases that are located on the same cluster. This is an Agent Manager limitation.|
|DDB-2745||The Memory Summary panel and the corresponding alarm display "null" when there are no child pools under a memory pool.|
|DDB-2706||If you have a Foglight for DB2 LUW agent that has never been used to collect data and you upgrade to Foglight for DB2 LUW 5.6.4 or later, you will not be able to activate and use the agent seamlessly. To activate and use the Foglight for DB2 LUW agent seamlessly, you must first create an Infrastructure agent and then manually set up resource mapping for that agent. For information on how to create an Infrastructure agent, see the Infrastructure Cartridge documentation. For information on how to set up resource mapping, see the Foglight Administration and Configuration Help.|
|DDB-2637||When the legacy Cartridge for DB2 LUW and Foglight for
DB2 LUW 5.5.x are installed on the same Foglight Management Server and
you upgrade the latter to Foglight for DB2 LUW 5.6.4 or later, the
online help for the legacy version is no longer available.
1. On the navigation panel, navigate to Administration > Cartridges > Cartridge Inventory.
2. Select the check box next to the DB2_OnlineHelp cartridge.
3. Click Disable to disable the cartridge.
4. Click Enable to enable the cartridge.
When you are finished, both online help versions are displayed in the action panel.
|DDB-2073||For DB2 version below 9.7, the CPU collected and displayed for a monitored instance is the CPU for only the monitored databases under that instance. The instance CPU does not include the CPU for any databases that are under the instance, and are not monitored.|
|DDB-1767||Monitoring a pureScale environment does not display locks when they are performed between two members (for example, one member is locking another member).|
When monitoring an instance running on Windows using a Foglight Agent Manager that is running on a non-Windows platform, open file descriptors are not closed correctly.
Workaround: On the Foglight Agent Manager machine, the "description" limit is configured to "1024". This value should be defined as "unlimited" or to a larger number, for example "65535".
Monitored environments with tablespace that have Korean characters in their name, will not be displayed correctly in the tablespaces dashboard graph.
The tasks listed below cannot be accomplished from the central Foglight Management Server (the federation master):
This release of Foglight for DB2 LUW supports adding databases to existing instances only using the Databases Management view in the Databases Administration dashboard.
The following is a list of third party issues known to exist at the time of this release.
Problem: WMI support is affected by the firewall on versions of Windows prior to Windows 7.
Workaround: For Windows versions prior to Windows Server 2008/Vista, use the following steps:
For Windows Vista and Windows Server 2008:
According to Microsoft (http://support.microsoft.com/kb/929851), the default dynamic port range for TCP/IP has changed in these versions. The new default start port is 49152 and end port is 65535. Subsequently, monitoring instances that run under these operation systems can be carried out by using either one of the following options:
Monitoring a DB2 instance which resides on Windows Server 2008 R2 requires the following workaround:
Some base values are not updated when using the Win32_PerfRawData_PerfDisk_LogicalDisk WMI class to calculate performance data in Windows Vista or in Windows Server 2008, because this class does not contain the PercentDiskTime_Base metric.
Workaround: A hotfix is available on Microsoft's Web site, at http://support.microsoft.com/kb/961435/en-us.
