Defect ID

Known Issue

DB2FOG-88

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.

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
DDB-5146

The DB2 installer does not support foreign languages on Windows machine.
The DB2 agent should be created manually through Foglight Administration > Agent Status.
The fields that needs to be modified are:

  • DB2 Host - the Physical Host the DB2 instance resides on
  • Port - DB2 port
  • User and Password for the DB2 instance
  • Monitored DB's - the associated Databases **The monitored databases secondary properties should be cloned first.
  • Monitored members - the associated partitions\members **The monitored members secondary properties should be cloned first.
  • DB2 home - DB2 home of the monitored instance

Once the agent was activated, the following errors may be occurred:

  • The agent will fail to detect standby (HADR) databases, so our collections will fail for those databases.
  • DB2_Log_File_Size collection will fail
  • The agent will fail to detect number of active databases, so the metric 'con_local_dbases' in the instance activity will not be set
DDB-3669 The Foglight for DB2 LUW 5.6.5.5 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.
Workaround:
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-1671

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".

GVFOG-60 The "Error executing script" error shows in the server log, if user clicks any tab or component on the Global View.
GVFOG-37 The Databases dashboard does not appear after user upgrades the Foglight for DB2 LUW to 5.7.5.37 using SPM installer.
N/A Need to wait for more than ten minutes between the upgrade of the Foglight Management Server and Foglight for DB2 LUW.

N/A

The tasks listed below cannot be accomplished from the central Foglight Management Server (the federation master):

  • Creating agents
  • Administering agents
  • Viewing a monitored instance from the federation master which is defined under two or more federation child server.

N/A

This release of Foglight for DB2 LUW supports adding databases to existing instances only using the Databases Management view in the Databases Administration dashboard.


Third party known issues

The following is a list of third party issues known to exist at the time of this release.

Cartridge-related issues

Defect ID

Known Issue

FOGDG-650

If the monitored DB host is shut down, upgrade of the Agent Manager hangs and the Agent Manager throws the error "Could not obtain a deployment lock. Will try again in 30,000 ms".

Workaround: use either of the following solutions:

  • Reconnect the DB host, stop the agent which connection is lost, and then proceed the upgrade again. 

  • Upgrade JDK to 1.8_u152 or later, and then restart the Agent Manager.

  • Delete the agent which connection is lost from the Agent Status dashboard, and then restart the Agent Manager.

DDB-1683

WMI-related issue

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:

  1. Open TCP port: 135.
    WMI by default uses the port range 1024 to 5000.

  2. Open up a range of ports above port 5000.
    Port numbers below 5000 may already be in use by other applications and could cause conflicts with your DCOM applications.
    It is recommended to have at least 100 ports opened, as several system services rely on these RPC ports to communicate with each other.

  3. Add the registry key, including additional ports.

    • Use the RPCCfg.exe (Windows Resource Kits) by running: rpccfg.exe -pe 5009-5009 -d 0

    • Manually add the registry keys under: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc\Internet

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:

  • Configure the firewalls to allow traffic between servers in the dynamic port range of 49152 through 65535 (less secure).

  • Limit the port range that is used in each monitored server.

N/A

Monitoring a DB2 instance which resides on Windows Server 2008R2 or higher requires the following workaround:

  1. Browse to http://www.quest.com/support/ and log in.

  2. Implement the instructions provided in solution SOL65870.

Windows-related issues

Defect ID

Known Issue

N/A

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.

Linux on IBM System z support

Foglight for DB2 LUW supports the monitoring of instances that are installed on Linux on System z. The supported monitored instance versions are the same as specified in the list above for the Linux platform.

Note: IBM® DB2® pureScale is currently not supported for Linux on IBM System z.

HADR support

Foglight for DB2 LUW supports monitoring an environment configured to use HADR by creating agents to monitor each one of the nodes separately (applies for both primary nodes and secondary).

Physical partition

Foglight for DB2 LUW supports a physical partition. When monitoring a physical partition, ensure you create the agent using the agent installer on the coordinator host.

Workgroup edition

Foglight for DB2 LUW supports monitoring a workgroup edition instance.

OS Cluster support

Foglight for DB2 LUW supports monitoring an instance that is installed in an OS cluster environment.

To enable monitoring, follow the instructions on “Host connectivity settings” screen in the installation wizard:
• Mark the "instance residing on an OS cluster".
• Make sure the virtual host name point to the virtual host name. This name will be used to install the DB2 agent and the IC agent.

pureScale support

Foglight for DB2 LUW supports monitoring a pureScale environment (except on Linux on IBM System z).
