About Dell

 


Welcome to Foglight for Infrastructure

Foglight™ for Infrastructure provides the ability to monitor an infrastructure environment and to analyze performance issues affecting various host systems. It provides system agents for local and remote monitoring of Windows® and UNIX® (including Linux®) hosts. The cartridge can be used - by itself - to monitor physical hosts, or - in combination with other agents - to monitor virtual hosts. The cartridge provides a service-based dashboard for easy monitoring and for quick access to relevant frequently-asked questions.  

These Release Notes cover the resolved issues, known issues, workarounds, and other important information about the 5.8.5.4 release of Foglight for Infrastructure. Review all sections before starting the installation.

For complete product information, see the Foglight for Infrastructure 5.8.5.4 User and Reference Guide.

Foglight Log Monitor

Foglight™ Log Monitor is an Infrastructure utility shipped with Foglight for Infrastructure which monitors log files and identifies activities that can potentially lead to performance issues.

Note: For complete information about Foglight Log Monitor, see the Foglight for Infrastructure User and Reference Guide.

Foglight for PowerVM

Foglight™ for PowerVM allows you to monitor IBM® PowerVM® environments. Foglight alerts you about infrastructure problems as soon as they develop, enabling you to resolve issues pro actively before end users are affected. Early intervention ensures consistent application performance at established service levels. Foglight for PowerVM monitors the health of your virtual system by tracking the levels of resource utilization such as CPU, network, and memory consumption of individual objects in your integrated environment.

Resolved issues and enhancements

Foglight for Infrastructure

The following is a list of issues addressed and enhancements implemented in this release.  

Defect ID

Resolved Issue

IC-2939

DellUnixAgent did not submit correct NIC utilization values.

IC-2936

Some Foglight for Infrastructure agents did not filter the loopback interface (for example, the IP addresses such as 127.*).

IC-2884

MultiHostProcessMonitorAgents did not collect metrics from Unix hosts if they did not previously connect to those hosts.

IC-2768 WindowsAgent and WindowsEventLogMonitor log monitoring now better handle duplicate log filters.

IC-2640

WindowsAgent was unable to obtain common topology information because the namespace returned by the connection was incorrect.

IC-2263 The vertical axis on the Send/Receive Rate chart used megabits (Mb) per second (s), instead of megabytes (MB)/s.
IC-856 UnixAgent on Solaris® reported 127.0.0.1 as one of its IPs.

Foglight Log Monitor

The following is a list of issues addressed and enhancements implemented in this release.  

Defect ID

Resolved Issue

IC-2701 Log Monitor record numbers used integer values as record numbers instead of long integers, causing unexpected errors when the number of log records exceeds the maximum allowed integer value.
IC-2663 After configuring the DellFileLogMonitor and DellWindowsEventLogMonitor agents, an IllegalArgumentException was found in the agent log file.
IC-2662 The DellFileLogMonitor agent could not collect and submit correct log files.
IC-2619 The same host shared object was shared among different activities, resulting in a warning message in the agent log file.

Foglight for PowerVM

This release of Foglight for PowerVM does not include any fixes or enhancements. It is made to accompany the 5.8.5.4 release of Foglight for Infrastructure.

 


Known issues

The following issues are known to exist at the time of this release.

Foglight for Infrastructure

 

Defect ID

Known Issue

IC-2943

DellUnixAgent stops collecting process details if Aggregate data for all instances of a program is disabled.

IC-2644

DellUnixAgent logs 'No begin line' when configured to monitor Solaris® on Foglight Agent Manager 5.8.1.
Workaround: Upgrade Foglight Agent Manager to version 5.8.5.

IC-2370

On the Infrastructure Environment dashboard, Uptime always displays "Not Available" for Solaris® zones.

IC-2058

Different cpu usage between Top CPU Consumers table and "topas" output on command line.

IC-1684

Network metrics may be unavailable when monitoring Solaris® LDOMs.

IC-1572

UnixAgent generates the IOException: error=12, Not enough space and no data is collected.

Workaround: This is a basic attribute of Java® processes that use a large amount of memory on Solaris®. The workarounds are either to reduce the amount of memory used by FglAM (perhaps by moving agents to other FglAM instances) or by increasing the swap space available to the Solaris® system. The root problem is described in the following Oracle® report: JDK-5049299 : (process) Use posix_spawn, not fork, on S10 to avoid swap exhaustion. Please note that the fix for this issue provided in this report is only for Solaris 10 and later). This is generally only an issue for agents monitoring the local system, but can also occur when agents run on the system in question, but are monitoring a remote system. They may still need to execute commands on the host system.

IC-1478

The Linux® data collector incorrectly identifies HP Smart Array physical disk as a logical disk.

IC-1440

Research if HP-UX agent might submit incorrect value for run queue length: includes active processes not just queued.

IC-1439

The Linux® agent submits incorrect value for run queue length; it includes active processes and not all blocked processes.

IC-1304

When parsing df output, make sure to account for the amount of space reserved in the filesystem.

IC-1253

Replace or augment the Event Log rule with a multi-severity rule.

IC-1163

When a UnixAgent monitors an AIX® system remotely, the remote monitor running quest_perfstat.bin fails with a timeout, and the following message is logged:

... Could not process metric query command: . Error: null

IC-1103

LinuxCollector on local host: Could not process metric query command: ... Error: null.

IC-1097

Network(receiveRate, sendRate, transferRate, utilization) can not be collected successfully while use non-native collector for AIX®, HP-UX agents.

IC-1093

The WindowsAgent does not remove invalid characters in log data before transmitting it.

IC-1049

While monitoring AIX® or HP-UX with the native collector, changing the user name of the credential used for monitoring generates an error related to the quest_perfstat.bin file.

Workaround: Before making changes to the credential, stop data collection on any AIX or HP-UX agent that are currently using those credentials. Failing to stop data collection causes the collector to generate an error indicating that it cannot execute a binary in the remote host's tmp directory. To enable the agent to resume data collection, delete the offending binary from the remote host machine.

IC-904

Mounted ISOs not reliably detected as read only.

IC-851

Selecting a severity level on a tile in the Infrastructure Environment dashboard filters the list of hosts to only that severity. If a host's severity level changes, the host remains in the list even if you refresh the page.

Workaround: If you leave the Infrastructure Environment dashboard and return, the filters are updated.

IC-811

The user installing or upgrading a cartridge will sometimes get an error when accessing views installed with the cartridge. This only happens if users go from the Cartridge Inventory dashboard directly to a Dashboard of the newly installed or updated cartridge (for example, the Infrastructure Environment dashboard does not render on first access after an upgrade).

Workaround: Refreshing the browser can often correct this problem. If this doesn't solve the problem, logging out and logging back in will clear the issue.

IC-747

Output from interactive shell during an SSH connection may cause errors when parsing command execution results.

IC-561

All Foglight for Infrastructure agents use the collection interval to calculate rate metrics. This is incorrect because a stop/start triggers a recollection before the interval expires.

Foglight Log Monitor

Defect ID

Known Issue

IC-2529

Foglight Log Monitor does not support the AIX® and Solaris® (SPARC®) platform with Foglight for Infrastructure 5.8.1.
Workaround: The Log Monitor executables, in a Foglight Agent Manager (FglAM) install, are stored in the <FglAM_home>/client/<client_version>/bin directory, based on their corresponding platform and architecture.

IC-1901

The Log Monitor page does not auto-refresh on Foglight Management Server version 5.6.5 to 5.6.10.
Workaround: Upgrade the Management Server to version 5.6.11 or later.

Foglight for PowerVM

 

Defect ID

Known Issue

AGENT-3716

PowerVMVirtualManager is not submitted when the PowerVM agent is running in an upgraded environment. For more details, see Troubleshooting Foglight for PowerVM.

AGENT-3232

The metrics in pop-up view of the dependency node should use the specific dependency time range, not the system time range.

AGENT-3218

The "PowerVM VIOS State Inspect" alarm does not display in the alarm table as expected when using a Firefox® 18.0 browser.

The "PowerVM Server Connect State" alarm has been cleared, but the warning icon of the specific server still exists when using a Firefox 18.0 browser.

Foglight Management Server

 

Defect ID

Known Issue

FGL-9001

Some processes generate alarms that disappear before the next sampling period.

Workaround: These alarms can be cleared manually.


Third party known issues

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

Windows issues

Defect ID

Known Issue

FDOC-4057

Collecting Logical Disk metrics from Windows Vista®, Windows Server® 2008, and Windows Server 2008 R2 may be affected by a Microsoft® defect.
Workaround: A hotfix is available on Microsoft's Web site, at http://support.microsoft.com/kb/961435/en-us.

FDOC-2771

In order for the WindowsAgent to have access to query WMI to collect OS and database metrics, the agent must have permission to access both DCOM and WMI.
On Windows Server® 2003, only users in the Local Administrators group on the monitored host have the required permissions.

IC-2856

Some Windows® processes report very large memory for virtual bytes performance counters (these are products marked with the large address space awareness flag, including Chkdsk.exe and Lsass.exe). The value is reported as such by Microsoft Windows on some 64-bit systems. This is a known 3rd-party issue; the values reported are as expected.

IC-594

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

IBM issues

Defect ID

Known Issue

FDOC-6474

Foglight for Infrastructure native AIX collector running on AIX® 6.1 hosts without "6100-07-04 Service Pack 04" may incorrectly report network metrics and utilization being collected. This issue has been acknowledged by IBM®: IV11918: PERFSTAT EXTENSION RETURNS STALE NETWORK/INTERFACE METRICS. APPLIES TO AIX 6100-07.

Workaround: A hotfix, IV11918, is available in various service packs and technology level packs. More information about the fix is available here: http://www-01.ibm.com/support/docview.wss?uid=isg1fixinfo134504.

End of support announcement

Cartridge for Operating Systems (Revised - August 2015)

The Cartridge for Operating Systems entered Limited Support as of October 2012. General support for this cartridge has now ended. This cartridge was not distributed with the 5.7.1 release of Foglight™.

Due to architectural limitations of the Cartridge for Operating Systems agents, certain agents should no longer be used. In particular, the Cartridge for Operating Systems’ SNMP Agent has specific security vulnerabilities. Customers using older (unpatched) operating systems should discontinue use of the SNMP Agent immediately. A new SNMP agent is included with this release of Foglight. This agent is licensed separately. Please see the SNMP cartridge release notes for details.

The Operating System agents, as well as the LogFilter, WebMonitor, and NetMonitor utility agents, have equivalent Foglight for Infrastructure agents, which should now be used. We have been working to close functional gaps between the old and new agents. Please contact your Sales or Support representative if you have specific concerns about using these agents.

We are aware of specific feature differences in the Foglight for Infrastructure agents that do not fully replace the AppMonitor agent. At this time there are no known incompatibilities or vulnerabilities in this agent. We are extending the Limited Support lifetime of this specific Cartridge for Operating Systems agent until June 2016, for customers using that agent in a pre-existing installation. Support cannot be provided for new deployments of this agent.

We are grateful for the feedback we have received from customers who require functionality provided by the Cartridge for Operating Systems. Those customers who have open support cases for specific compatibility concerns should contact their Support representative for the current status of those requests.

 


Troubleshooting

This section provides a list of references which address the most commonly faced issues relating to remote connectivity, allowing for easy troubleshooting using the vendor's information knowledgebase or Foglight documentation:

Foglight for PowerVM

Symptom:

When Foglight Management Server is upgraded from version 5.7.5.x to 5.7.5.3, the server reports the error "Object being merged of type PowerVMVirtualManager has incomplete identity: PowerVMVirtualManager.host". The PowerVMVirtualManager and PowerVMVirtualCenter are not submitted successfully, and the UI does not display the data for the HMC domain.

Resolution:

Use the following commands to edit the PowerVMVirtualManager:

def topSrv = server.TopologyService;

def type = topSrv.getType("PowerVMVirtualManager");

tmp = topSrv.beginUpdate(type);

tmp.removeProperty("host");

topSrv.endUpdate(tmp);
