Foglight 5.9.4 - Administration and Configuration Guide

Foglight Configuration

The Federation view contains information about the server federation. Federation is a Foglight feature that addresses the needs of customers who monitor large-scale environments that are naturally partitioned into logical units. Each of these partitions is traditionally served by one Foglight Management Server instance and its distributed clients/agents. Federation enables the use of one Management Server to operate, while using other Management Servers as the data source. The Federation Master Server manages the operation of those units, merging their data into a central model. Clicking an entry in this view drills down to the Foglight Server Topology view.

This view displays the following information:

The High Availability view indicates if Foglight is running in High Availability (HA) mode. Configuring Foglight in HA mode allows you to run multiple servers in a JBoss partition offering HA. For more information on starting Foglight in High Availability mode, see the High Availability Field Guide.

This view displays the following information:

•	Status shows if Foglight is running in HA mode () or not ().

The Server view displays information related to the Foglight Management Server.

The view shows the following settings:

This view contains information about federation settings. The federation settings are defined in the file <foglight_home>/config/federation.config. For more information about this file, see the Federation Field Guide.

The Federation view displays the following settings:

This view contains information about database settings. The database settings are defined in the file <foglight_home>/config/server.config. For more information about this file, see the Installation and Setup Guide set.

The Database view displays the following settings:

This view contains information about JVM settings.

The JVM view displays the following settings:

The JVM settings that appear in this view are not the full set. By default, the Foglight launcher sets a number of additional JVM settings. To see all of the JVM parameters, look for them under VM Options in the log file for the current session, <foglight_home>/logs/ManagementServer_<date>_<time>_001.log, as shown in the code listing below that illustrates the default JVM settings.

The OS view contains information about the OS of the machine on which the Management Server is running.

The view displays the following settings:

The WCF view contains information about the Web Component Framework (WCF) included with the Management Server.

The view displays the following settings:

This view shows the email settings that are used by Foglight to send messages to specified recipients. For example, you can configure Foglight to generate and send reports to a specified mail recipient, or email warning messages to Foglight administrators when certain thresholds are reached. For information on how to configure email actions in Foglight, see Configuring email notifications.

IMPORTANT: In some situations you need to create or receive email alerts that contain a URL to the browser interface. To ensure the URL points to the computer on which the Management Server is running, ensure that the CATALYST_URL registry variable contains the correct computer name and port number.For example: http://MyHost.MyDomain.com:8080/For information on how to look up Foglight registry variables, see Working with Foglight Registry Variables.

The Mail (Global Settings) view displays the following settings:

IMPORTANT: The mail.connection.timeout variable does not come with Foglight. To configure the global connection timeout, you need to create this variable and set it to a desired value.

IMPORTANT: The mail.socket.timeout variable does not come with Foglight. To configure the global socket timeout, you need to create this variable and set it to a desired value.

This view lists the ports used by Foglight.

The Ports view displays the following ports:

For complete information about the above ports, such as their default numbers or communication points involved, see Default port assignments.

The following table shows the default port assignments for the ports listed in the Ports view along with a few other ports that are used for communication with the database or internal application ports. The port numbers can be specified at installation time, or after the installation using the configuration parameters in the file <foglight_home>/config/server.config. For more information, see the Installation and Setup Guide set.

NOTE: In addition to the ports listed below, in some configurations, the Management Server may use additional ports, such as the ports used by JGroups which is the underpinning component of Foglight HA. JGroups is a toolkit for reliable multicast communication. In a default configuration, it dynamically allocates some UDP ports for the communication between cluster members. Network traffic from those ports does not go beyond the local subnet. Therefore, no special firewall configuration is needed.

The Foglight Management Server supports to configure a new language for a PDF report. Once this language is imported, users can view the PDF report without installing this language as it has been embedded into the report by default.

Some Foglight dashboards have reports associated with them. This allows you to run a report based on the current dashboard. You can generate the report using the Reports menu in the top-right corner.

The Management Server Configuration dashboard is associated with the Management Server Configuration Report. Run this report by selecting Management Server Configuration Report from the Reports menu, and specifying the input parameters in the report wizard.

The report wizard provides more information about the Management Server Configuration Report and instructions on how to set the input values. For more information about reports in Foglight, see the Foglight User Help.

Connection Status

The Connection Status dashboard lists the users that are logged in to the Management Server. For each user, the list shows the client IP address, login time, request name, and request time.

View Audit Information

Use the View Audit Information dashboard to explore log entries. Log entries show the users that are logged in, changes made to user security settings, or any changes made to rules, schedules, or registry variables. Select a time period for which you want to view the logs, and optionally, print the desired set of entries to a file.

IMPORTANT: The appearance of the dialog box may be different, depending on the type and version of your web browser.

IMPORTANT: If you show or hide one or more columns in the audit log table, this layout is reflected in the export file. For example, if you display only the time range and the operation name, only those columns appear in the export file.

The following table lists the operations that are audited by Foglight. In addition to the operations listed below, Foglight audits the following operations:
