How to monitor domains in Foglight

In Foglight, domains are monitored components grouped together by a common technology. For example, operating systems are grouped together in the Infrastructure domain and application servers are part of the Custom Applications domain. Domains represent parts of your environment that you are interested in monitoring.

Each technology type is considered a subdomain. For example, each type of operating system in the Infrastructure domain is a subdomain. Use the Domains dashboard to monitor your environment if you are a domain Administrator or simply prefer to think of your environment in terms of domain groups. This dashboard allows you to obtain a high-level view of the state of your monitored domains and investigate problems in a particular domain. It also shows you what domains you are not monitoring, but could be.

Access the Domains dashboard from the Welcome page by clicking Homes | Welcome | View Your Enterprise Health | View Enterprise Health Organized by Monitoring Domain

TIP: You can also access the Domains dashboard from the navigation panel: select Homes | Domains

The Domains Dashboard

 

Viewing detailed information for a domain or subdomain

Drill down on a domain name to view a high-level summary of its monitored components. For example, click Infrastructure to view all monitored virtual and physical hosts in the Hosts dashboard.

By default, the Domains dashboard shows only top-level domains. Expand a domain node to view its subdomains.

Each monitored subdomain comprises the actual instances of that technology type in your environment. Click a subdomain name to drill down to details about it. For example, click Linux to navigate to the list of Linux hosts or click Oracle to drill down to the Oracle Global View
 

Investigating Problems in a Domain

Use the Domains dashboard to monitor for problems in your domains — for example, to see if a domain is in a Critical state, or if any alarms have been fired for its components — and take action on them.
 

Investigating a Domain or Subdomain’s State

By default, a domain or subdomain reflects the current worst state (normal, warning, critical, or fatal) of its components.

Click the State icon to investigate the state of a domain or subdomain that is displaying a warning, critical, or fatal icon.

A popup appears that lists the domain or subdomain’s alarm sources (for example, hosts, application servers, or databases) and their health. These are the components that contributed to the domain or subdomain’s state.

Depending on the problem you are investigating, do one of the following to drill down to more detailed views:

• Click an alarm source to drill down and see more details about it.
• Drill down to views that display the health of all alarm sources.
• Drill down to view the health of the current object (for example, Infrastructure domain or the Linux subdomain).
• Drill down to view all outstanding alarms for the domain or subdomain.

 

Investigating a Subdomain’s Health

Foglight displays each monitored subdomain’s recent health in the History column. This column summarizes the subdomain’s health for the dashboard’s time range.

The colored segments in the column represent the subdomain’s alarm severity state at different intervals within the time range. Yellow segments represent warning alarms, orange segments represent critical alarms, and red segments represent fatal alarms. Green segments represent intervals without alarms.

To investigate the health history:

1. Hover the cursor over a segment in the health history bar to display a popup with a list of related alarms that occurred during that interval.
2. Click the health history bar. A more detailed Health History view appears.
3. Click and drag the timeline to zoom in on an interval in the bar. The chart zooms in on the selected time range. (TIP: After zooming in, hover the cursor over the bar to cause the zoom menu to appear. To restore the previous time range used by the bar, click the Previous Zoom icon ( ). To restore the bar’s timeline to its initial state, click the Restore Zoom icon ( ). To freeze the dashboard’s time range at the same interval spanned by the bar’s zoomed-in range, click the Update page with zoomed time range icon ( ).)
4. Click a red, orange, or yellow segment in the detailed health history bar to find alarms that are causing the host to be in a non-normal state during that interval. A popup with details about the alarms that fired during that interval appears.

 

Investigating a Subdomain’s Alarms

The counts in the Alarms column represent the total number of alarms fired for the components in a subdomain; for example, for all monitored virtual hosts in the Infrastructure | VMWare subdomain.

Use this column to view the number and type of alarms fired for these components during the dashboard’s current time range.

Click an alarm to display a popup that contains the standard alarm list. 

Investigating Problems with a Subdomain’s Agents

You can view the state of the agents related to a subdomain in the Agents column.

Click a warning, critical, or fatal state icon to display a list of agents with health problems or drill down to the Agents dashboard. For more information, see the online help for the Agents dashboard.
