Logging in to Foglight

 
* 
NOTE: The Management Server must be running before you can log in to Foglight.
To log in to Foglight using a web browser:
1
Open a web browser and type the following:
http://<hostname>:<port>
Where <hostname> is the name of the machine where the Management Server is installed and <port> is the HTTP port specified during installation (the default is 8080).
2
Enter a valid user name and password and click Login.
 
* 
NOTE: The Foglight browser interface requires JavaScript. Ensure that you have enabled JavaScript in your web browser before you attempt to log in.

Monitoring the Management Server host

During the installation, or upgrade, a HostAgent is automatically created to monitor the host where the Management Server, the embedded Foglight Agent Manager, and embedded database run. The health of this host directly affects the health and performance of Foglight.

To view the HostAgent:
1
Start the Management Server.
For detailed information, see Starting the Management Server .
1
Log in to Foglight.
2
On the navigation panel, under Dashboards, click Administration > Agents > Agent Status.
3
On the Agent Status dashboard, find the UnixAgentPlus called EmbeddedHostMonitor.

Information about the status and data collection of the agent are available on this dashboard.

To view the data that the HostAgent collects for the Management Server host:
1
On the navigation panel, under Dashboards, click Infrastructure.
2
From the Select a Service list, select the service for the host.
3
On the Monitoring tab, select the host from the list.

For more information about monitoring activities and exploring the data collected for the host, see the Foglight for Infrastructure User and Reference Guide.

Running the Management Server FAQ

Why do I see an extra process named Quest Process Runner when I run Foglight?

On UNIX®, Foglight uses the Quest Common Process Runner to run processes such as the embedded database, the embedded Agent Manager, and command actions.

Why does the error message “cannot restore segment prot after reloc: Permission denied” appear when I start the Management Server?

Newer Linux® distributions have enabled new kernel security extensions from the SELinux project at the NSA (National Security Agency). SELinux is an NSA project to improve the security of Linux through Mandatory Access Control (MAC). These extensions allow finer-grained control over system security. However, SELinux also changes some default system behaviors, such as shared library loading, which can be problematic to third-party programs.

If you see the error message “cannot restore segment prot after reloc: Permission denied” when you start the Management Server, your SELinux configuration is preventing IDL (the Interface Definition Language) from launching.

To rectify this issue, you can perform one of the following workarounds:

•
Change the default security context for the Management Server by issuing the command:
chcon -t texrel_shlib_t <foglight_home>/jre/lib/i386/*.so
chcon -t texrel_shlib_t <foglight_home>/jre/lib/i386/server/*.so
•
Disable SELinux altogether by setting it to disabled in your /etc/sysconfig/selinux file:
SELINUX=disabled

For more information about SELinux, consult your Linux® distribution vendor.

If I stop the Management Server by closing the Command Prompt window, an error appears when I start up the server again. How do I restart the server?

It is recommended that you do not use this method to stop the Management Server. However, if you do use this method, follow the following workaround.

1
If you are running the embedded database, stop the database manually before restarting the Management Server.
2
Remove the stale .pid file that is located in the state directory. The logs or the console output inform you which .pid file to remove when you restart the server.
Why does the “JavaScript Disabled” error message appear when I try to log in to Foglight?

The Foglight browser interface requires JavaScript. You may need to modify the security settings in your web browser to enable this functionality. Depending on your browser, this setting may be labeled either “Enable JavaScript” (for example, in Firefox®), or “Enable Active Scripting” (for example, in Internet Explorer®).

Why does clicking the login link on the server startup page not work?

The default link to the login page points to http://localhost:8080. In some instances, this link may not correspond to the URL of your Foglight server, resulting in the link not working. This issue can also occur when Foglight is not able to identify your local host. Add your host/IP information to the etc/hosts files to correct this issue.

Why does a link-local IPv6 address not work with the Foglight web user interface?

Configuring the Management Server with a link-local IPv6 address is not supported because many web browsers do not support link-local IPv6 addresses. To correct this issue, update your host/IP information in the etc/hosts file.
