Migrating Agents

The SQL Performance Investigator extension is only supported on Windows 64-bit. As a result, you may need to migrate SQL Server agents from an Agent Manager running on Linux to a Windows Agent Manager.

In addition, the migration tool allows you to perform resource balancing between the agent managers running SQL Server agents with and without the SQL PI extension installed.

To migrate an agent to a different Agent Manager:
1
Open the migration wizard by navigating to Dashboards > Databases > Support Dashboard > Databases Technical Support > Database Agents Migration > SQL Server.
2
Select the Agent Manager that is the destination host for the migrated SQL Agents. Click Next.
3
On the SQL Agents for Migration pane, the left-hand column displays a list of available Agent Managers. Select an Agent Manager to view a list of the agents installed on it.
4
From the list, select the agents that you want to migrate and move them to the Agent Manager Destination column.
5
If necessary, select agents and set the Windows credentials.
6
Click Next to migrate the agents.
7
When migration has completed, click Finish to exit the Wizard.

About Monitoring Extensions

During the installation process you can choose to install and configure one or more of the monitoring extensions. The monitoring extensions provide a more in-depth analysis of the monitored instance and the environment it is running on, creating a whole and unified status.

Understanding the Foglight for SQL Server Architecture

The communication architecture of Foglight for SQL Server is presented below.

Figure 2. Communication Architecture overview.

SQL Performance Investigator Extension

SQL Performance Investigator allows you to rapidly identify bottlenecks, anomalies, and application trends by focusing on top resource consumers and providing multi-dimensional SQL domain drilldowns. SQL PI allows you to:

•
Monitor real-time SQL Server database performance at a glance
•
Gather and diagnose historical views
•
Identify and anticipate performance issues
•
Analyze and optimize execution plan changes
•
Compare day-to-day values to identify anomalies and application changes
 
* 
NOTE: SQL Performance Investigator requires a license. If you are using a trial version and would like to request pricing, contact Quest Support.
* 
NOTE: SQL PI requires a repository database that is installed automatically on the Agent Manager.
Operating System Extension

Monitoring the operating system allows you to identify resource consumption and provides a full view of the server health. An Infrastructure agent, which is created automatically as part of the monitoring process, monitors the operating system.

 
* 
NOTE: The Operating System extension is enabled by default.
VMware Extension

Monitoring the VMware system allows you to identify resource consumption and provides a full view of the data center and ESX health when the server is part of a VMware environment.

Installing and Monitoring a Single SQL Server Instance

Enabling the Foglight Management Server to monitor SQL Server instances requires the creation of the Foglight agents that monitor these instances and ensuring that these agents communicate properly with the Foglight Management Server.

Foglight for SQL Server provides a graphic, intuitive method for creating and configuring multiple agents, which can be used instead of Foglight’s default method for creating agents and editing their properties using the Agent Administration dashboard (see About the Foglight for SQL Server Agent in the Foglight for SQL Server Reference Guide). Foglight for SQL Server allows running a wizard that provides a common entry point for adding and discovering all database instances within a user-specified range, and then configuring these instances for monitoring.

 
* 
IMPORTANT: When running Foglight for SQL Server in a Federation architecture, neither the creation nor the administration of agents can be accomplished from the central Foglight Management Server (the Federation Master). These two tasks should be carried out from the stand-alone Management Servers (the Federated Children).
To run the instance installation wizard:
1
On the navigation panel, click Homes > Databases.
2
Click the SQL Server tab in the middle of the Databases View, and then click Monitor.
The Monitor SQL Server Instance dialog box appears.
* 
NOTE: If a user-defined database group is selected, the databases table's title displays the name of this group instead of All; however, all newly discovered or created databases are added to the general (All) group of databases.
 
3
Choose the agent manager on which the agent is running. The default is the agent manager with the least agents installed.
a
Click the Agent Manager Host link located in the bottom left corner of the dialog box.
A dialog box appears with a list of all agent managers connected to the Foglight management server.
b
Select the appropriate host name and click Set.
 
* 
IMPORTANT: You have the option set this host as the default for all future installations.
4
On the Monitor SQL Server Instance dialog box, provide Connection Details by typing:
•
Server name — for the default instance, specify the host name. If you have more than one instance on the server, you must name the instances using the format: domain\user name.
•
Port — Optional. This field can be left empty, unless the TCP/IP connection port is not the default port: 1443.
5
Specify the SQL Server 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
Use SSL: Select whether an SSL connection should be used.
7
Select an Alarm Sensitivity Level to determine what level of alarms the system stores and displays for this instance. The default is Normal. Alarm levels include:
•
Essential — Store and display only critical or fatal alarms.
•
Normal — Store and display most alarms — essential and best practices; only critical and fatal statistical alarms.
•
Tuning — Store and display all SQL Server alarms sent to Foglight.
•
Performance — Store and display only availability and SQL PI related alarms.
8
Optional — In the Monitoring Extension pane, click the Click for Licensing Information link under SQL PI. You are prompted to contact Quest Sales for an add-on license to enable SQL Performance Investigator (PI).
9
Optional — In the Monitoring Extension pane, click the Operating System link.
To configure the extension, choose the connection details of the host on which the SQL Server instance is running:
•
Log in to the host using the same account used for monitoring SQL Server — This option is set by default when the SQL Server connection details are of types: Active Directory (AD) Authentication or Using the Active Directory account running your agent manager.
•
Log in to the host using different log in credentials — logging in through either of the following authentication methods:
•
Windows: Log in through a Windows account. The user name should be entered in the domain\username format (for example, COLUMBIA\JSmith).
•
Local User: Log in through the same credentials that are used to run monitored software on the SQL Server host. The user name should be entered in the domain\username format (for example, COLUMBIA\JSmith).
•
SSH (login credentials): Log in through a user account on Linux.
•
SSH (RSA): Log in through a RSA key on Linux.
•
SSH (DSA): Log in through a DSA key on Linux.
10
Optional — In the Monitoring Extensions pane, click Collect VM statistics.
To configure the extension, select the connection details of the vCenter or ESX on which the SQL Server instance is running:
•
The name of IP address of the vCenter server that hosts the SQL Server instance virtual machine, or the name of its parent ESX server
•
The port number used by the vCenter server system or by ESX server for listening to the connections from the vSphere Client (default: 443).
•
The name and password of the user that has the privileges required for connecting to the vCenter server or ESX server and retrieving information.
11
Click Monitor.
 
* 
IMPORTANT: 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, (for example: insufficient privileges, incorrect credentials or an Agent Manager that reached its full monitoring capacity.
12
When the installation completes successfully, the Monitoring Initialized Successfully dialog box appears. Click Add another Database or Finish to exit.

Discovering Multiple Instances to Monitor

You can use the instance installation wizard to discover existing instances. This option allows you to discover instances and monitoring them by entering several methods:
