Foglight for Application Operations 5.9.8 - Dependency Mapping User Guide

Managing global dependencies

The Manage Global Dependencies dashboard helps Foglight users with the Advanced Operator role to manually ignore or restore dependencies in the environments, to easily monitor only the components of interest. Ignoring a dependency is useful in the case where some dependencies are not meaningful. In general, it is best to set the agent settings to correctly filter detected dependencies, but in some cases it is easier to use the ignore feature to achieve the same filtering.
To access this dashboard, click Manage Global Dependencies in the Dependency Mapping Administration dashboard.
Figure 5. The Manage Global Dependencies dashboard.
The dashboard includes two tabs:
•
Active dependencies - displays all active dependencies in your environment.
•
Ignored dependencies - displays all dependencies ignored from your environment.

Active dependencies

Use the Active Dependencies tab to explore the list of dependencies that have been observed in the time range, or that are otherwise active (depending on the type of dependency). This list does not include ignored dependencies.
 
Table 14. Active dependencies information.
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 written by 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”.
To filter the list of dependencies that you want to explore:
•
In the Active Dependencies tab, select the components that you want to exclude from the dependency maps (select their corresponding check boxes) and click Ignore.
The selected dependencies are removed from the Active Dependencies table. They are added to the Ignored Dependencies table.

Ignored dependencies

Use the Ignored Dependencies tab to explore the list of dependencies that have been excluded by users from the dependency maps.
Table 15. Ignored dependencies information.
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).

To filter the list of ignored dependencies:
•
In the Ignored Dependencies tab, select the ignored dependencies that you want to see on the dependency maps (select their corresponding check boxes) and click Restore.
The selected dependencies are removed from the Ignored Dependencies table. They are added to the Active Dependencies table.

Dependency detail

The Dependency Detail dialog box shows the observed dependencies which make up the selected connection (for the selected row). It contains the following tabs:
•
Netstat Dependency Details view shows the connection count for the selected Netstat agent, when applicable. Other types of dependencies may show other details. These details are optionally collected, based on the advanced settings configured for the agent.

•
Dependency Summary view shows a complete summary of the selected item, including host to host dependencies, process and host summaries, or any default summary view for any type of object. Other types of dependencies may show other details.
