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).
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 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.

Editing process-tier mappings

The Edit Process-Tier Mappings dashboard helps Foglight users with the Advanced Operator role to configure regular expressions to match processes to tiers. These regular expressions are used by the Dependency Mapping service creation to auto-suggest services based on these processes (for details about service creation, see Build services from service suggestions).

These regular expressions are evaluated in the order in which they appear in the Edit Process-Tier Mappings dashboard. The cartridge is delivered with a set of default regular expressions, which cannot be deleted, but can be modified or enabled/disabled as needed. Users can add, modify, remove, and enable or disable user-defined expressions.

To access this dashboard, on the Dependency Mapping Administration dashboard click Edit Process-Tier Mappings.

Figure 8. The Edit Process-Tier Mapping dashboard.

Table 16. Edit Process-Tier Mapping table.
Column Name	Column Description
Up	Regular expressions are evaluated in the order in which they appear in this table, starting with the top row. Click the Up arrow to move an expression one level up in the evaluation list.
Down	Regular expressions are evaluated in the order in which they appear in this table, starting with the top row. Click the Down arrow to move an expression one level down in the evaluation list.
Enable	Regular expressions are taken into considerations during the evaluation if they are enabled and are skipped if they are disabled in this table. Click the / button to disable/enable an expression, as needed.
Expression	Definition of the regular expression matching a process to a tier.
Tier	Tier to which a process should be assigned when the regular expression is matched.
Description	Additional details about this regular expression.
Edit	Click Edit to modify the definition of an existing regular expression.

To add or modify a regular expression:

To add: click the Add

icon located at the top of the table.
To modify: click the Edit

icon located in the Edit column.

The Configure Process-Tier Mapping dialog box appears.

Provide or modify the following information:

•

In the Expression field, specify the definition of the regular expression.

•

From the Tier List drop-down, select a tier to which the process should be assigned when the expression is matched.

•

In the Description field, add details about the regular expression.

Click Save.

The new/updated regular expression definition appears in the table.

To remove a regular expression:

Select the check box associated with the expression you want to remove.


	IMPORTANT: You cannot remove the default regular expressions installed with the cartridge.

Click the Remove

icon located at the top of the table.

A confirmation dialog box appears.

Click OK to confirm the operation.

The regular expression definition is now removed from the table.

Use the Select All and Select None buttons at the top of the table to select or clear all the check boxes associated with user-created regular expressions. Note that the default regular expressions cannot be selected or cleared.
