Known issues

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

Note: Check the release notes for each cartridge you will be using for known and late-breaking issues with that cartridge. 

For a list of known issues for Foglight Agent Manager in this release, see the Foglight Agent Manager 5.9.5 Release Notes.

Workflow Automation is Not Supported in Federation or High Availability Configurations

Foglight for Automation is not supported:

  • On a Foglight Federation Master.
  • When Foglight is configured to use the High Availability features.

 

See below for details. These limitations will be addressed in a future release.

Workflow Automation is Not Supported in High Availability Configurations

When a Foglight Management Server running in High Availability mode fails over, all in-progress tasks fail and the system cannot recover them.

Workflow Automation is Not Supported on Foglight Federation Masters

The Foglight Cartridge for Automation should not be installed, and workflow automation must not be used, on a Foglight Federation Master. This is because active tasks that update topology objects are not permitted on the Federation Master. Workflow automation may be installed and used on the Federated Child(ren) as usual.

Management Server

Defect ID

Known Issue

WCF-15913

Custom rules (which are copied from existing cartridge rules) will drop some tables or charts that exist in the original Alarm dialog. Contact Quest Support for workaround.

FGL-20201

After installing 5.9.5 on Linux minimal install, users may not be able to access certain dashboards and see errors in the logs.
Workaround: To fix the issue, do the following:
1. Install the dejavu font package.
    Ubuntu: sudo apt-get install ttf-dejavu
 
  CentOS/RHEL: sudo yum install dejavu*
2. Install fontconfig.
    Ubuntu: sudo apt-get install fontconfig
    CentOS/RHEL: sudo yum install fontconfig
3. Rebuild the Linux font cache.
    fc-cache -f -v
4. Restart Foglight.

FGL-20162

Running Foglight 5.9.5 on Windows Server 2008 requires upgrading PowerShell to version 3.0.

FGL-19877

Upgrading to version 5.9.3 completes successfully but the installation log contains shortcut creation failures.

FGL-19479

The Management Server UI will possibly be displayed abnormally if Tomcat version is upgraded.

 Workaround: Clear the cache data of your web browser.

FGL-19431

If you toggled enable/disable state for Alarm Integration, Incident Integration, Clear Integration Alarm, or QMX Agent Host Connection Rule rule in the Integration cartridge, its enable/disable state will be reset after upgrading to 5.9.x from 5.7.5.8. 

FGL-19283

When upgrading the Management Server from 5.7.5.8 to 5.9.x, unexpected CartridgeDeploymentException shows in the log file.

Workaround: This exception only occurs in environments with those cartridges which define Java Archive or JBoss Artifacts component, like Integration and IntelliProfile cartridges. JBoss Server has been removed from the Management Server 5.9.x. As a result, JBossDeploymentHandler, which was used to handle above components, has also been removed from the Management Server 5.9.2 or later. If you encounter this issue, you could ignore it as this exception does not impact upgrade of the Management Server and relevant cartridges. 

FGL-18953

EU appliances may fail connecting the Foglight Management Server after the initial installation of Foglight Management Server.
Workaround: Restart the Foglight Management Server after the installation. 

FGL-18611

LDAP accounts may fail binding to the OU group whose name includes backslash characters '\'. This can prevent Foglight to authenticate LDAP users.

FGL-18470

FSMService availability calculations do not work as expected in a service hierarchy.

FGL-18125

FoglightShutdownAction.checkInUsedPort() does not load port settings from server.config during an upgrade.

FGL-18122

FGL-18076

The Management Server data-driven multiple severity rules may fire multiple times for the same severity in case of concurrent data submissions.

FGL-18075

The rule engine may pass non-persisted alarm IDs to rule actions. This can prevent some alarms, that are generated multiple times against the same scoping object, from firing.

FGL-18034

PostgreSQL fails to start up while installing the Management Server with an embedded PostgreSQL database on a Korean OS.

FGL-17845

Failing to start the Management Server with the --host=*.*.*.* option due to a failed attempt to start the embedded database.

FGL-17826

LDAP users may have to log in twice to get proper role assignments.

FGL-17769

Foglight is configured with a list of default ciphers. Some of these ciphers are potentially vulnerable ciphers. A review of the ciphers that will be available in a future release is ongoing.

Workaround: Edit the list of ciphers by completing the following steps:

  1. Open the following file for editing:

    • Releases prior to 5.7.1: <FMS_HOME>/server/deploy/jboss-web.deployer/server_https.xml

    • 5.7.1 release and later: <FMS_HOME>/server/tomcat/server.xml

  2. In this file, specify a list of ciphers in the ciphers attribute of the secure connector:

    <Connector executor="tomcatThreadPool" maxHttpHeaderSize="8192" URIEncoding="UTF-8" scheme="https" secure="true" SSLEnabled="true" clientAuth="false" keystoreFile="../../config/tomcat.keystore" keystorePass="nitrogen" sslProtocol="TLS" sslEnabledProtocols="TLSv1.2,TLSv1.1,TLSv1" bindOnInit="false" ciphers="COMMA_SEPARATED_LIST_OF_CIPHERS"/>

FGL-17415

ObservationQueryPlan$QueryStep.getDayIndex(...) can result in ArrayIndexOutOfBoundsExceptions during a Daylight Savings Time (DST) change.

FGL-17162

Core monitoring policy derivations are not deployed on a Federated Master.

FGL-17055

Excluded objects are sometimes included in a Federation topology synchronization.

FGL-17015

A Foglight Agent Manager that is no longer in use maintains a stale disconnected RemoteObject instance under the host object. This causes the host to appear as undefined on the Hosts dashboard, even though the host is monitored by Foglight for Infrastructure.

FGL-16508

When federation.config does not contain any queries, TopologySynchService mistakenly logs the following warning:

WARN Obsolete federated topology object purge will not be performed because the following federated servers are not connected: ...

FGL-16487

Topology loading can fail for topology objects that have been converted to DataObjects.

Browser interface

Defect ID

Known Issue

FADUI-1149

An attempt to import external groups results in the following error:

Could not execute the requested operation, error(s) had occurred: Failed to retrieve groups, please make sure you correctly configured the Directory Services, check log for details.

The log, however, does not contain any errors.

FGLUI-11228

After changing the value of the registry value, some of the performance calendars may disappear from the list.
Workaround: To correct the display and allow performance calendars to be deleted, return to the main Manage Registry Variables page, then navigate back to the appropriate registry value.

FGLUI-11009

When editing properties from the Agent Status dashboard or the Agent Properties dashboard in Chrome 17, some edit fields are not available.
Workaround: Use a different browser when editing agent properties through these dashboards.

FGLUI-10834

The Cartridge Inventory page is currently unable to alert users if a cartridge install fails due to lack of space in the server's temp directory. An error is written to the log files.

FGLUI-10788

When editing secondary agent property tables from either the Agent Status or Agent Properties dashboards, performing Add and Delete operations at the same time results in all Added items being deleted.
Workaround: Add items to the table, save them, and close the popup window, then edit the secondary property again and delete the rows that need to be deleted. Finally, save and close the popup window. This ensures that the added items remain.

FGLUI-10504

Selecting the time range "All" on the Service Details dashboard can result in the page getting stuck refreshing. Avoid using the "All" time range on this page.

FGLUI-10456

Selections made on the Service Selector tab of the Select services and tiers to monitor dialog box of the SOC become unselected when you switch to the Tier Selector tab and back again.

FGLUI-10323

The first time the Environment Report is run it may generate a warning: "com.quest.wcf.core.component.RenderPDFContext - Text ... did not fit. in view ..."
This is a benign warning that is caused by one of the values read from the environment being too large for a page.

FGLUI-10036

Credential alarm messages sometimes contain UUIDs for objects related to the alarm.
Workaround: Show the Alarm Detail dialog for these alarms to resolve the objects to identifiable names.

FGLUI-8261

When using a Federation Master that is a newer version than the Federated Child, it is possible to get warnings about missing metrics. This occurs when new metrics have been added to the Federation Master's version. The warnings indicate that the Federated Child does not provide these metrics, and they will cease when the Federated Child is upgraded to the same version as the Federation Master.

FGLUI-7817

When editing secondary agent property lists, the Delete Selected Row(s) button marks the rows to be deleted by graying them out. Save changes must be selected to delete the selected rows. If a required field is blank, then a value must be entered before the row can be marked for deletion.

FGLUI-7729

In the Service Builder and Service Operation Console (SOC) dashboards, when alarm filters are configured, they are applied to the main dashboards (Service Builder and SOC dashboards) and to some first level popups only. The alarm filters are not applied throughout all popups/drilldowns at any level.

FGLUI-7593

When reviewing Alarms on a Federation Master, you are able to open a link to view the rule that fired the alarm on the Federated Child. This involves opening the console of the Federated Child. If the Federated Child is of an older version than the Federation Master, an error page is displayed.

FGLUI-7377

Under rare conditions, if the session is allowed to expire while viewing some of the views in the Administration dashboard, the process of logging in again displays the Administration view without any decoration around the side panels.

Workaround: To clear this condition, close the browser. Do not save your session if the browser prompts you to save the last session configuration. Instead, start the browser and log in again.

FGLUI-7356

The column layout on the Agent Status Page does not allow resizing of columns, which can result in the host name appearing truncated.

FGLUI-7333

An error message stating "Error getting value of context entry with key:timeRange" can appear in the logs when using the popup menu on the Origin field of the Alarm Details dialog.

FGLUI-6874

If a Federation Master Server connects an older version Federated Child, the Federated Child may have some of the objects that are no longer associated with the Management Server Performance Report and Foglight Server Diagnostic views on the Federation Master. This results in some data about the Federated Child being unavailable to this report and views.
Workaround: Go to the Federated Child to view detailed information.

FGLUI-5990

Inconsistency in the number of alerts shown in the "All Alarms Chart" and "Alarm List with Filter" in the Alarms dashboard.

FGLUI-5708

Display all available scoping objects in the condition editor for copied and user-created rules.

FGLUI-4628

On systems with a large numbers of hosts, the Host Table view can be slow to display.
Workaround: Use the hide column feature to hide the sparkline (small graph) columns. This significantly improves the display performance.

FGLUI-4544

Foglight 4 Tabular views generate an error when the time range has "Auto" granularity.

FGLUI-3509

The edit rule definition for an alarm from a Federated Child brings up a page for editing a rule on the Federation Master, rather than for the rule that triggered the alarm. This occurs because it is not possible to perform administration from the Federation Master.

FGLUI-3440

When the user pastes data using right-click > Paste to a box that automatically updates itself (for example, the edit agent properties screen), the user interface does not automatically refresh itself.
Workaround: After pasting into an Agent Properties text field, press the Spacebar > Backspace, and click the Save button.

FGLUI-3430

When agent activation fails, the "Activating" status box does not show the status of the failed start agent.

FGLUI-1906

The Service Levels Details page does not show cleared alarms for Service Level Policy.

FGLUI-257

Seconds should be displayed in the startTime and endTime in the WCF under Browse > Data when granularity is set to "raw".

WCF-13385

QP5 needs to be upgraded to the latest version.

WCF-12581

In Internet Explorer 8, when the number of dashboard nodes in the navigation panel exceeds the maximum that can be displayed without a scrollbar, the scrollbar does not immediately appear.

WCF-10580

Tree Table list nodes should not be clickable or dwellable.

WCF-7344

The following is a list of third party issues known to exist at the time of this release. For a list of third party issues related to the Foglight Agent Manager at the time of the Foglight 5.9.5 release, see the Foglight Agent Manager 5.9.5 Release Notes.

Defect ID

Known Issue

FGL-5691

The Foglight Management Server generates an "Unable to load Java VM shared library to start JVM" message when attempting to start the Management Server on a Red Hat Enterprise Linux Server 5.0 VMware machine.

This is caused by the SELinux security code on newer RedHat systems. There are two workarounds:

  • Enter the following command (as root):

    chcon -t textrel_shlib_t <foglight_home>/jre/lib/i386/server/libjvm.so
     

  • Disable SELinux on the system in question.

This issue is addressed in the Sun JDK 1.6.0 release notes:
http://www.oracle.com/technetwork/java/javase/6u4-140071.html
Bug: 6538311
This bug affects both Foglight Management Server executables (fms and fmsha).

FGL-3677

Installation: Console Mode. Returning to a previous step in the installation process after being prompted for a user password, the input is not recognized.
During a console mode install, it is possible to return to the previous step by typing "back" and then pressing the Enter key. If done while the installer is asking the user to enter a password, all subsequent user inputs are automatically changed to asterisk symbols (* ) and are unreadable by the console.
Workaround: Type quit and reinstall again.

FGL-2882

Installation: Console Mode. Some characters of the Administrator's password are not hidden if typed too quickly.
This issue has been observed when installing Foglight on some older machines.
Workaround: Avoid typing the password fast.

WCF-9735

When typing words containing "ss" in the online help search, a null pointer exception is generated.
This is a known issue for applications that use Oracle's default implementation of the Java Help Search functionality.

 


Upgrade and compatibility

Upgrade and compatibility

Important:

  • To upgrade from a 5.5.x Management Server to 5.7.1 or later, you must first upgrade to 5.6.2 (or a more recent 5.6.x version), and then to 5.7.1 or later.
  • To upgrade from a 5.6.11 Management Server to 5.7.5.x, you must first upgrade to 5.7.1, and then to 5.7.5.x.
  • To upgrade from a 5.7.5.x Management Server to 5.9.x, you must first upgrade to 5.7.5.8, and then to 5.9.x.
  • Foglight Management Server (5.7.0 to 5.7.5.8) no longer supports authentication of Federation actions (such as clearing alarms) without specifying a secure token in the federation.config file. Previously configured installations in which Federated Master and Children were authenticated without a security token no longer allow authenticated actions. For more information, see the Federation Field Guide.
  • In the 5.9.x release, configuration of SecurityToken in the federation.config file (adopted from Foglight 5.7.0 to 5.7.5.8) has been removed. Therefore, configuring an SSL for Federation is required when you upgrade the Federation environment to release 5.9.x, if your Federation environment configures SecurityToken before. For more information, see the Federation Field Guide.
  • Foglight for SQL Azure is not compatible with the 5.9.x release. If you have these products installed, you must NOT upgrade to this version of the Management Server.

See the Foglight 5.9.x Upgrade Guide for information about upgrading Foglight and for a list of the latest cartridge versions that are compatible with Foglight Management Server 5.9.5.
