Appendix: Configuring Monitoring of Non-English Windows OS Hosts

Dependencies tab

The Dependencies tab focuses on observed (or manually asserted) relationships between elements (or elements contained within a service). On this tab, monitor service dependencies with the following rollup levels:

•

Application Infrastructure: shows dependencies (manually created or observed) between hosts. This option is useful to system administrators whose primary focus is to monitor the services from a host perspective (for example, “which hosts have recently reported dependencies?”, “what processes run on a host?”).

Figure 17. Application Infrastructure view

•

Services: shows dependencies (manually created or observed) between services. This option is useful to system administrators whose primary focus is to monitor the services and their nested child services.

Figure 18. Services view

•

Virtual Environment: shows hosts and applications components grouped by physical host, and arranged by tier. It takes the Application Infrastructure rollup and puts it in perspective of the ESX or Hyper-V servers.

To display the content of the Dependencies tab in full-size view:

•

Click Full screen on the right side of the Show drop-down list.

The Dependencies for <service_name> view opens to show the service selected in the SOC and the rollup level selected in the Dependencies tab.

In this view, you can do the following actions:

•

Select a service from the list of services already defined in your system (use the Select a service drop-down list).

•

Select the rollup level to show for the selected service (use the Show drop-down list).

•

Display any objects that are outside the selected service (use the Show dependencies outside of <service_name> check box).

•

Drill down and view more dependency details about a host or service on the map by clicking an element on the map.

•

Return to the Service Operations Console dashboard by clicking Service Operations Console in the breadcrumb trail.

In the Dependencies tab, you can also display any objects that are outside a selected service but have observed dependencies with other objects inside that service.

To show all dependencies (inside and outside a selected service):

•

Select the Show dependencies outside of <service_name> check box in the upper-right corner of the tab.

The view is updated to show all observed dependencies between objects inside and outside the selected service.

In the upper-right corner, the Dependencies tab provides a NAVIGATOR slider. Use the slider to set the zoom level between 50% and 150%.

From the Dependencies tab, you can drill down and view more details about any component on the map (host or service). For host components, you can also view detailed information about any application components running on these hosts.

To display dependency details for a component:

•

Click the component of interest on the map.

The <component_name> Details dialog box includes several tabs (Summary tab, Dependency Details tab, and Close-up Graph tab) and provides information about how sub-components are connected. It may also include other context-sensitive tabs for different types of objects.

Summary tab

The information presented in this tab varies depending on the selected component. See Dependencies tab.

The following illustration shows an example of information provided for a host that has one application component. The banner (upper part of the tab) displays the CPU, Storage, Memory, and Network allocations for this host. The lower part of the tab displays a tile associated with the application component related to the host. The content of this tile is specific to the application component type. For detailed information about tiles and their content, see the Foglight for Application Operations User Guide.

From this tab you can navigate to the Host Monitor dashboard by clicking More Details. Use the Host Monitor dashboard to further investigate the performance of the host.

The following illustration shows an example of information provided for a host that includes several application components. The banner (upper part of the tab) displays the host name, and the Service Level Compliance status. The lower part of the tab displays a tile for each application component related to the host. The content of these tiles is specific to the application component type. For detailed information about tiles and their content, see the Foglight for Application Operations User Guide.

From this tab you can navigate to the Service Details dashboard by clicking More Details. Use this dashboard to further investigate the performance of the selected service.

Dependency Details tab

This tab presents detailed information about the dependencies observed for the selected host, and the number of incoming and outgoing dependencies. For more information, see Dependencies tab.

Table 21. Dependency Details tab data
Column Name	Column Description
From	The host or object which is directly dependent on the item in the To column (that is, the dependency client).
To	The host or object which is directly depended upon by the item in the From column (that is, the dependency server).
Detail	Short text summary of the dependency (for example, httpd.exe->mysql.exe), or the comment of the creator of the manual dependency. Click the details link to open the Dependency Detail dialog box. For more information, see Dependency detail.
Dependency Source	Pointer to the agent which created the dependency. If the dependency was manually created, this column displays “Manual Dependency”.
