Rules Collections and Metrics

Opening the Databases Administration Dashboard

You can edit agent settings for one or more SQL Server instances on the Databases > Administration dashboard.

* 
NOTE: If you attempt to select instances of more than one type of database, such as an SQL Server database and an Oracle database, an error message is displayed.
To open the Databases Administration dashboard:
1
In the navigation panel, under Homes, click Databases > SQL Server.
2
Select the check boxes beside one or more SQL Server instances.
3
Click Settings and then click Administration.
The Administration dashboard opens, containing settings for all the selected agents. Settings are broken down into categories, which are organized under a SQL Server tree.

Reviewing the Administration Settings

The Databases Administration dashboard allows settings options for collecting, storing, and displaying data, which apply to all the currently selected agents. Click a category of settings on the left (for example: Connection Details) to open a view containing related settings on the right.

The metrics defined under the Databases Administration dashboard apply to all of the agents that were selected before opening the Databases Administration dashboard. As a result, the same unit of measure and aggregation value for display are enforced for all currently selected agents.

The SQL Performance Investigator category allows you enable or disable SQL PI for the agents selected. In addition, you can also start or stop change tracking for the agents.

To view the full list of selected agents, click the Selected Agents button at the upper right corner of the screen. To change the list of agents to which the metrics will apply, exit the Databases Administration dashboard, select the requested agents and re-open the view.

If the settings vary between the selected agents (for example: one agent uses the measurement unit kilobyte, while another uses megabyte), the fields that contain non-identical values are displayed as empty and marked with an Inconsistent Values () icon.

Changes made to settings should be saved before selecting another category of settings.

To save changes made in an Administration dashboard view:
1
In the Database Administration dashboard, select a category from the menu.
2
Make changes to settings as necessary.
3
Click Save changes at the bottom of the view.
If you attempt to exit the view without saving changes, a Warning dialog box prompts you to confirm your action.

Defining Connection Details

Use the Connection Details category to define global connection settings, which apply to all instances and hosts selected in the view. You can configure SQL Performance Investigator connectivity, enable user-defined collections, and set VMware connection details.

Defining the Connection Settings for the Monitored Instances

The Connection Details view contains a table that displays all the agents that were selected before entering the Databases Administration dashboard.

To define the connection settings for the requested agents:
1
Select the check boxes to the left of the agents for which uniform credentials are to be set.
2
Click Settings, and then click Administration.
The Administration dashboard opens, containing settings for all the selected agents.
3
Click Connection Details, and then click Set credentials.
The Set dialog box used for editing the credentials of the selected instance appears.
* 
IMPORTANT: If multiple instances were selected before clicking Set credentials, this dialog box is empty (does not display the instances’ names, ports, and connection details). The default options in such a scenario are Windows authentication (for SQL Server connection details) and the use of existing host connection details (for OS monitoring).
4
On the Edit Credentials pane, provide port connection details. This field can be left empty, unless the TCP/IP connection port is not the default port: 1443.
5
Specify the SQL Server login credentials using either of the following authentication methods:
•
Active Directory (AD) Authentication — log in using the Active Directory account running on your agent manager or typing a new AD account. The user name should be typed in the following format: domain\user name.
•
SQL Server Authentication — log in using a SQL Server account
6
Optional — Select whether an SSL connection should be used. The default is set to Off.
•
SSL Connection Off — SSL is not required
•
Optional — SSL is required; if the server doesn't support SSL, a plain connection is used instead (default method)
•
Mandatory — SSL is required
7
In the Monitoring Extensions section you can select and configure which monitoring extension to add to the monitored instance:
•
Operating System — Correlate the SQL Server OS resources with the entire host.
* 
NOTE: Note: Monitoring OS can made also by using stored credentials - Select this link to open the Stored Credentials dialog box, which allows reviewing the login credentials and authentication methods used for logging in to Foglight. Foglight stores encrypted credentials in lockboxes, which may be password-protected for added security. The Credentials dialog box, DB-Agent Lockbox. If credentials have already been entered in another lockbox, use the Lockbox list to select from that lockbox.
•
VMWare — Collect VM statistics.
8
Click Set.
9
On the Connection Details pane, click Test Connection.
* 
NOTE: If the monitoring verification fails click the message that is displayed on the Status column and resolve the issue according to the instructions that appear in the dialog box. For example, insufficient privileges, incorrect credentials or an Agent Manager that reached its full monitoring capacity.
Upon successful completion of the process, the status shows as Verified.
10
The option of enabling and editing credentials for user-defined collections is available also when multiple instances are selected. This option is carried out as follows:
a
Click Set UDC Credentials.
The dialog box Edit Credentials for User-defined Collections appears.
b
Select the check box Enable user-defined collections.
c
Select whether to perform the collection:
•
Using the current agent credentials
•
Manually specifying login credentials.
•
Using Windows authentication and the Windows account that is running Foglight.
d
If the option of manually specifying login credentials was chosen, select the requested authentication method from one of these options:
•
Windows authentication — type a user name and a password in the domain\username format (for example, COLUMBIA\JSmith).
•
SQL Server authentication
* 
IMPORTANT: If the Foglight Agent Manager that runs the instance resides on a UNIX host, the option of using Windows authentication and the Windows account that is running Foglight is unavailable.
e
Click Set to return to the dialog box used for editing the instance’s credentials.
* 
IMPORTANT: To add user-defined collections, go to the User-defined Collections view in the Databases Administration dashboard. For details, see Configuring User-defined Collections .
11
If you have SQL Server instances that run on virtual hosts, such instances require setting a dedicated connection profile, in order to connect to the requested VMware server.
Establishing such a connection is necessary in order to retrieve the Virtualization overhead data, that is, the percentage of CPU that is unavailable to this virtual machine because it is being utilized either by other virtual machines or by VMware itself. The Virtualization Overhead indicator is displayed in both the real-time and history summary pages.
To edit the VMware Connection Profile:
a
Select the requested agents. To select all agents, select the check box on the table’s title column.
b
Click Edit.
The Edit VMWare Credentials dialog box appears.
c
Select the check box Enable collecting VMWare CPU allocation data.
d
Enter the details required for monitoring the CPU distribution data, that is, host, port, VMware user, and VMware password.
e
Click OK.
If multiple agents were selected, the settings will apply to all agents.
12
Ensure that all requested data has been entered. If so, click Validate.
A progress bar appears.
At the end of this process, any connectivity issues are indicated by the Status column of the agents table. This column displays either the status Verified for the instances that connected successfully to the database, or a status that indicates failure of the connectivity verification process, and the reason for the failure (for example, Login failed for user “X”).
If the connectivity issue results from faulty login credentials, modify the credentials and carry out again the connection verification process. If the database to which the instance tries to connect is not running, clear the box near the database’s name.
If some of the instances whose verification failed display a status of either Insufficient privileges, Click to Grant or Wrong sysdba Credentials, such instances should be granted privileges, by clicking the status and using one of the following methods:
•
Manually, using a script (by clicking View script, copying the text and using it to grant privileges
•
By clicking the button Grant privileges.
The Grant Privileges dialog box appears.
If Insufficient Privileges are indicated, this dialog box allows specifying a SYSAdmin (System Administrator) user with sufficient privileges.
Enter a SYSAdmin user and password, and then click Grant Privileges.
13
Click Save Changes.
The Applying Modified Settings progress bar appears.
Upon successful completion of this process, the Status column of the instance table displays the status Changes applied. For instances that failed verification, the status column indicates that changes cannot be saved if the validation did not complete successfully.
