Known issues

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

Cartridge-related issues

 

Defect ID

Known Issue

n/a

In case SQL PI for Oracle is monitored side by side with SQL PI for SQL Server, you must upgrade both Foglight for SQL Server and Foglight for Oracle cartridges to the same version.

n/a

In case of mixed environments (Linux® and Windows®), upgrading Foglight for Oracle to the latest version causes the agent monitored by SQL PI with SQL PI repository on Linux to stop monitoring.

ODB-12520

The following homepages were removed from the custom dashboards: Interconnect/GCS, Cluster Overview, Sessions, Instance identification and usability and Workload.

ODB-11467

In environments configured to use Agent Manager in High Availability mode the chosen Agent Manager hosting the SQL PI repository will host watchdog and maintenance agents that cannot participate in the Agent Manager high availability utility.

ODB-10907

The following dashboards and views may be less responsive than others due to their complexity:

  • Storage > Tablespaces and Datafiles > Tablespace details > Free Space Fragmentation

  • Storage > Tablespaces and Datafiles > Datafile I/O Details > Fragmentation

  • Activity > Locks > Locks Tree (Current) tab & Locks Historical Tree tab

ODB-10918

Support for Oracle 12c has the following restrictions:

  • Oracle 12c Flex ASM is not supported.

  • On the database agents' Administration > Oracle > Collection Settings screen, the Tablespace Settings tab is disabled. Tablespace Storage collection settings cannot be edited for Oracle 12c.

ODB-10154

In order to allow the agent to connect to the remote Windows Management Instrumentation (WMI) components on Windows Server 2008 R2 or Windows 7 systems, special registry settings are required. For details, see section Configuring Registry Settings for Windows Server 2008 R2 and Windows 7 in Agent Manager Guide.

ODB-10060

When a UNIX-based Foglight Agent Manager, which is selected for monitoring a Windows-based Oracle or ASM cluster, is using virtual IP to connect to the Oracle or ASM instance, the OS connection validation fails.

Workaround: Use the virtual IP /physical IP/physical host name.

ODB-10015

The following secondary parameters are not cloned when creating an agent using the Oracle Monitoring Installer:

  • Collection Details and Environment Variables parameters in Exadata agent

  • Exclude Diskgroups parameter in ASM agent

Unless these parameters and cloned and modified by the user, the upgrade process will override them with the default values.

ODB-9950

Oracle monitoring installer does not support validation for the required sudo commands. Therefore, the sudo user should be prepared before using it. For details, see Foglight for Oracle User Guide.

ODB-9739

When editing the properties of the Foglight Agent Manager concentrator (Dashboards > Administration > Agents > Agent Status), the name of the Foglight Agent Managers should be entered in the Downstream FglAMs section exactly as they appear in the topology, under Home > Agents > All agents > <Agent name> > RMI data > Fglam host property.

ODB-9738

In an environment that includes a Foglight Agent Manager concentrator, when upgrading the environment where the concentrator does not contain any regular agents, the concentrator is not upgraded. Therefore, after the upgrade process takes place the Foglight Agent Manager concentrator has to be deployed manually.

ODB-9291

Using a virtual name when creating a CRS agent is not supported by either the CRS installation wizard or the Silent Installer tool (command line installation); both tools only support using a physical name or an IP address.

ODB-9290

The CRS installation wizard does not support using the connection type Local user, when the monitored host runs on UNIX.

Workaround: use command line installation (CLI) through the Silent Installer tool, which supports this configuration.

ODB-9215

The Global Administration does not support the CRS, Exadata and ASM agents. As a result, any modification of the settings of the collection frequencies, retention policies, alarms and email notifications for these agents can be carried out only using the default Foglight tools.

ODB-9144

After upgrading an Oracle agent that was created manually the verification process fails even if the agent works properly, and the Status row displays the message DB connection failed.

ODB-9143

Exadata, ASM and CRS agents are marked in the upgrade process as 'other agents', even thought they are Oracle agents and should be marked as such.

ODB-9129, ODB-9337

When selecting the RSA key connection type in the Exadata, ASM, and CRS installers, after loading the id_rsa file, the dialog box Add Cells is automatically refreshed, thereby resetting all other fields in the dialog box (Host name, User, Passphrase, Port, and sudo) and leaving them empty.

ODB-8697

The Exclude Tablespace feature allows inserting tablespaces only by using the Java regular expression syntax, rather than wildcards.

ODB-8272, ODB-8128

Foglight for Oracle supports monitoring OS clusters residing on VMware machines only in the configuration of one OS cluster node per data center; monitoring is not possible if two or more cluster nodes are located on different data center, to provide disaster recovery.

ODB-8298

Upgrading an ASM agent that was created manually will result in a malfunctioning ASM agent that requires reconfiguration, unless the following fields in the agent settings are cloned: ASM Instances, Host Details, Environment Variables, Collection Details, and Exclude Diskgroups.

ODB-7982, SU-2542

Tablespace-related data collection on a monitored RAC is now unaffected if a single node or node agent fails; The requested data will be submitted by the RAC's other nodes.

ODB-7463

Upgrading an instance that has a legacy OS cartridge installed on its host will result in creation of the database agent without the creation of the infrastructure agent.

Workaround: create the infrastructure agent manually.

ODB-7457

When converting RAC One Node to RAC the OS cluster failover alarm is triggered.

ODB-7454

The invalid objects exclude list is not supported for RAC and RAC One Node.

ODB-7452

Setting the connection details of a RAC One Node and failing the validation, will result in failure to save the changes.

ODB-7446

The following alarms are displayed in the RAC level instead of the instance level:

  • Usability Availability Single

  • Collection status

ODB-7427

The Listener graphs under the Usability dashboard are not populated with data when monitoring RAC One Node.

ODB-7208, ODB-7169

The current implementation does not support collecting listener data from remote Windows hosts using Windows local execution (the user that is currently running the agent manager).

ODB-7171

The following metrics display NA when monitoring a RAC one node:

  • Paging

  • Page in

  • Page out

ODB-7064

"Challenge response" credentials do not appear in the advanced lockbox pop up.

ODB-6939

Customers that are monitoring instances using nslookup/IP and are upgrading to the new version of the product should create the infrastructure cartridge agents themselves manually.

ODB-6784

Version 5.6.4 and above of the product uses only SSH to connect to Unix hosts. Customers upgrading from previous versions of the product that were using telnet will now be converted to use SSH

ODB-4417

User-defined collections that return a variant number of columns (such as select * from ...) will only retrieve the columns that existed during its creation. Any additional columns will be ignored.

ODB-4002

Using the administration module to configure the sessions screen parameters for a single node in a RAC environment will result in all the RAC nodes being configured with the same parameter.

ODB-3029

Creation of user-defined collections for a RAC database should be executed by selecting the RAC agent itself and not the RAC and its nodes.

ODB-2984

In the Global Administration > User-defined Collections screen, it is possible to create two collections that bear the same name with a different capitalization (for example: MyCollection and Mycollection); however, only one collection will appear in the topology, and be displayed on the User-defined Collections panel.

ODB-2829

When running user-defined collections on dynamic tables, deleted items are still kept in the topology. As a result, the number of rows displayed on the user-defined collections table will exceed the configured value for maximum allowed rows.

ODB-1465

Monitoring database backup via the Databases > Database Backup panel is not supported in Oracle® version 9i.

 

SQL PI Repository

Defect ID

Known Issue

ODB-13138

When PI is enabled: 

  • Microsoft Visual C++ 2010 Redistributable Package or later needs to be installed on Foglight Management Server and Foglight Agent Manager.

  • Mixed (Windows® and Linux®) environments are not supported.

ODB-13128

PI agents that use the PI repository on Linux® stop working when upgrading the Foglight for Oracle cartridge.

It is recommended to recreate these agents on a Windows®-based PI repository.

n/a

The SQL PI repository is supported for Agent Managers that reside on: 

  • Windows 2008 and later

  • Linux (RHEL 6, CentOS 6, SUSE 11) and later versions

n/a

Installing SQL PI repository is not possible on an Agent Manager installed on Linux with user root.

n/a

SQL PI repository and the Agent Manager running the monitoring Oracle agents (with the SQL PI extension), can reside on Windows64 or Linux64 OS platforms in either combination, as follows:

Foglight-related issues

Defect ID

Known Issue

ODB-9536

If a CRS, Exadata, or ASM agent is created, deleted, and then recreated with the same name, the nodes from the previous installation will be added to the newly created node.

Workaround: Use the relevant tab in the Databases dashboard (ASM, CRS, or Exadata) to delete the nodes.

ODB-9393

A Foglight Agent Manager (FglAM) residing on a Linux/UNIX machine cannot use Windows Remote Management (WinRM) to establish connection with Windows server. Connection using WinRM can only be carried out by a an Agent Manager residing on a Windows machine.

ODB-7358, INTP-11

Raising baseline alarms requires setting the percentage of deviation from the dynamically defined baseline which, when met or exceeded, an alarm will be invoked.

For example: If the normal CPU utilization is 50%, allowing alarms to be invoked when the CPU utilization meets or exceeds 55% requires setting the deviation percentage's value to 10.

SSDB-7241, WCF-12907

In Foglight, it is possible to create a recursive service, which calls itself and thereby causes an endless loop. If you create such a service, the Databases dashboard cannot be not displayed.

SSDB-881

Enabling and disabling an older version of Foglight for Oracle while a newer version is installed may adversely affect the performance of the newer cartridge.

Workaround: Disable the newer cartridge and enable it again, thereby overriding the settings of the older cartridge.

CR-2987

Problem: When the FMS (Foglight Management Server) and FglAM (Foglight Agent Manager) are installed on different time zones, the timestamps in the topology are not accurate. The difference from the real timestamp is:

  • +|time difference between FglAM and FMS|
    or

  • –|time difference between FglAM and FMS|.

CR-2153

Problem: A Validate Win connection failure occurs. If the Win32_PerfRawData_PerfOS_Processor class is invalid, any queries from it will fail. This is used in the OS connections validation.

n/a

Agent names must be unique. Foglight does not support the same agent name to be applied to more than one agent.

 


Third party known issues

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

Defect ID

Known Issue

ODB-10750

Due to an Oracle issue on version 12C pluggable, the Datafile Fragmentation and Tablespace Fragmentation collections retrieve data for cdb$root only.

n/a

Oracle Bug 18195919: When monitoring Oracle 12C the Activity > Datafiles I/O Activity dashboard does not show tablespaces of type TEMP.

n/a

WMI-related issue

Problem: WMI support is affected by the firewall.

Workaround: For Windows versions prior to Windows 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 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 an Oracle instance that resides on a Windows 2008R2 requires a workaround as follows:
- Browse to http://support.quest.com/ and log in
- Perform solution SOL65870

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 site, http://support.microsoft.com/kb/961435/en-us.

 


Upgrade and compatibility

A direct upgrade to Foglight for Oracle 5.7.x is only available from version 5.5.8 or later. Customers that are running earlier versions of the product must first upgrade to version 5.5.8 and then upgrade to version 5.7.x.

Note: The Foglight for Infrastructure agent will not be created in the following scenarios:

 

Foglight for Oracle 5.7.5.35 requires Management Server version 5.6.11 or later and Agent Manager version 5.7.0 or later.
