4 1 Introduction to this Guide Welcome to the Foglight for SQL Server. This guide is a quick guide for the installation and use of Foglight for SQL Server, from the planning stage up to the actual monitoring of database instances. This document details first the installation prerequisites, including the required permissions, and then the actual monitoring of database instances. This guide is intended for SQL Server database administrators. Installing Foglight for SQL Server Foglight for SQL Server is Dell Software's powerful diagnostic and problem resolution tool for Microsoft SQL Server databases. This Foglight cartridge delivers a global view that provides a visual instance health check, and enables a drill-down style diagnostic workflow to investigate the performance of monitored SQL Server instances and databases. This chapter describes the installation of Foglight for SQL Server, from the planning stage up to the actual installation. Installation Prerequisites Before starting the installation of Foglight for SQL Server, ensure that the following conditions are met: Having the required permissions; for details, see Foglight for SQL Server Permissions on page 5. Using a supported system and platform. Foglight for SQL Server s system requirements and supported platforms are identical to those of Foglight Management Server. For details, see Foglight System Requirements and Platform Support Guide. Using a Foglight license that allows cartridges to be installed. Alternatively, use the embedded trial license. Ensure that the pre-existing Foglight license that is being used allows cartridge installation. If a license that does not allow cartridge installation is used, the installation wizard cannot proceed beyond the Foglight for SQL Server Management Server License screen, which requires specifying the type of license to be installed. Using an available external database IMPORTANT: The available external database requirement is relevant only if you plan to install a new Foglight Management Server: If you plan to install Foglight Management Server on an external database, ensure that this database is running. The supported external database platforms and versions are as follows: SQL Server Oracle 4

5 MySQL Preparing in advance a SQL Server user to be used for monitoring the discovered instances. The SQL Server user is created exclusively for monitoring a specific database, and has limited execution capabilities. The details of this SQL Server user are entered in the Connection Details dialog box when running the Database Discovery wizard (see Configuring Foglight for SQL Server on page 9), and this user must be granted the privileges required for monitoring the database. These privileges can be granted only by a user with a SYSADMIN server role. NOTE: In SQL Server 2000, monitoring the selected instances can be carried out only by a user with a SYSADMIN server role, in which case the Grant Privileges phase is unnecessary. Foglight for SQL Server Permissions Foglight for SQL Server can be used for granting permissions on several levels. This following sections describe the permissions that can be granted to users of SQL Server at each level, and instruct how to manually run the grant privileges script. Granting Permissions to SQL Server Users Permissions are granted on several levels, as described in the following sections: Instance-level Permissions on page 5 Database-level Permissions on page 5 Object-specific Permissions on page 6 Instance-level Permissions The following permissions are granted at the instance level: VIEW ANY DEFINITION VIEW SERVER STATE ALTER TRACE allows the following operations to be carried out: Tracing a specific session the data retrieved by this operation is displayed on the SQL Activity > Sessions > Session Details > Session Trace pane Monitoring deadlocks the data retrieved by this operation is displayed on the SQL Activity > Deadlocks panel Database-level Permissions The following permissions are granted at the database level: CREATE USER the lowest permission level, which only allows accessing each database. db_datareader allows user-defined SQL queries to be created for monitoring purposes, via the Userdefined Collections global administration screen. For details, see the User-defined Collections section in Managing SQL Server Database Systems: User and Reference Guide. db_ddladmin allows DBCC commands to be run for indexes. In the absence of this a permission, no data will be retrieved from the following collections: Database Index Density Vectors Database Index Details Database Index Histogram 5

6 Figure 1. Click on a specific row on the Databases > Indexes pane to retrieve data from these collections. Object-specific Permissions The permissions listed below allow users holding them to access specific objects within the master and msdb databases: Execute allows the following objects to be accessed within the master database: xp_enumerrorlogs xp_readerrorlog Select the following objects within the msdb database to be accessed: log_shipping_monitor_primary log_shipping_monitor_secondary log_shipping_primaries log_shipping_secondaries sysalerts syscategories sysjobactivity sysjobs sysjobhistory dbm_monitor_data Running the Grant Permissions Script The file used for granting permissions manually, SQLServerGrantPrivilegesScript.sql, can be downloaded by clicking the link View script under the Instances table, accessible via one of the following methods: At the end of the installation process, when the Status column of the instance table displays the status Insufficient database privileges, clicking this text brings up the Insufficient Database Privileges dialog 6

7 box. For details, see section Carrying out the Advanced Instance Installation Wizard in the Managing SQL Server Database Systems: User and Reference Guide. In the Connection Details global administration screen, If some of the instances whose verification failed display a status of either Insufficient privileges, Click to Grant or Wrong sysdba Credentials, clicking this text brings up the Insufficient Database Privileges dialog box. For details, see section Global Administration > Connection Details in the Managing SQL Server Database Systems: User and Reference Guide). Figure 2. If instance verification fails, an error is dislayed. View script This dialog box allows specifying a SYSAdmin (System Administrator) user with sufficient privileges. Enter a SYSAdmin user and password, and then click Grant Privileges. Alternatively, click the View script link, to the right of the Grant privileges button, to grant privileges manually via a script IMPORTANT: Running this file requires having the sysadmin or securityadmin server role. To manually run the Grant Permissions script: 1 Go to Dashboards > Administration > Cartridges > Components for Download. 2 Double-click DB_SQL_Server_Cli_Installer. 3 Click Download. 4 Extract the DB_SQL_Server_Cli_Installer.zip file. 5 Copy the following files: MSSQLPermissionsCheck.sql MSSQLPermissionsGrant.sql 6 Open the SQLServerGrantPrivilegesScript.sql file in SQL Server Management Studio (SSMS). 7 Find the Select@LoginName =? section in the beginning of this file. 8 Replace the question mark with the login name to which the requested permissions are to be assigned. 9 Execute the script. Repeat step 1 to step 4 for each instance to be monitored. 7

8 Installing Foglight for SQL Server Foglight for SQL Server runs on the Foglight Management Server, which is its operation framework. Therefore, Foglight Management Server must be installed before installing the cartridge. The installation of Foglight for SQL Server can be carried out using either of the following scenarios: Installing both Foglight for SQL Server and Foglight Management Server. For details, see Installing Foglight for SQL Server and Foglight Management Server Together on page 8. Installing Foglight for SQL Server as a cartridge from within an existing Foglight Management Server. For details, see Installing the Cartridge by Adding it to a Cartridge Inventory of an Existing Foglight Management Server on page 8. Installing Foglight for SQL Server and Foglight Management Server Together Starting from version 5.5.8, a single executable file allows installing Foglight Management Server together with Foglight for SQL Server. To run the combined installation file: 1 Copy the installation file suitable for the operating system and the bit level (32-bit or 64-bit) to a temporary directory on the requested host. IMPORTANT: The combined installation file is named using the following convention: Foglight-<version_number>_FoglightForSQL-Server--<version_number>_<operating system>-<bit level><.exe/.bin> For example: Foglight-5_6_11_0-FoglightForSQL- Server-5_6_7_508_windows-x86_64.exe 2 If planning to use an external database for the Foglight Management Server Installation, ensure that this database is running. 3 Follow the on-screen installation instructions. Installing the Cartridge by Adding it to a Cartridge Inventory of an Existing Foglight Management Server To install Foglight for SQL Server as a cartridge: 1 Copy the cartridge s car file (DB_SQL_Server-VersionNumber.car; for example, DB_SQL_Server- 5_6_7_508.car), which is included in the installation media, to your local computer. 2 Log in to the Foglight browser interface. 3 In the browser interface, on the navigation panel, click Dashboards > Administration > Cartridges > Cartridge Inventory. 4 On the Cartridge Inventory dashboard, click Browse to find the car file on your local computer. 5 Click Install Cartridge. 8

9 Configuring Foglight for SQL Server 2 After successful installation of Foglight for SQL Server, when entering the Foglight Management Server, no instances are displayed. The Foglight for SQL Server agent (DB_SQL_Server) allows you to monitor the database performance on each server where the application is installed. The agent installer allows monitoring of existing and running instances for Foglight monitoring. To discover database instances, when no instance is monitored: 1 On the navigation panel, under Homes, click Databases. A blank screen appears, with a message indicating that the agent installer should be used for setting up the monitored environment. 2 Click Add > SQL Server in the upper left corner of the Databases View. The Monitor SQL Server Instance dialog box apears. 3 Choose the agent manager on which the agent will be running The default is the agent manager with the least agents installed. a Click the Monitoring agent will run from host <agent manager> 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 pane, 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: Specify the SQL Server credentials using one of the following authentication methods: Windows Authentication log in using a Windows user account. The user name should be typed in the following format: domain\user name SQL Server Authentication log in using a SQL Server account Use the Windows account running your agent 6 Optional In the Monitoring Extensions pane, click the SQL PI monitoring extension. You are prompted to choose the Agent Manager on which the SQL PI repository will be installed. 7 Optional In the Monitoring Extensions 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: Windows Authentication or Using the Windows account running your agent manager. 9

10 Log in to the host using different login credentials - logging in through a Windows user account. The user name should be entered in the domain\username format (for example, COLUMBIA\JSmith). 8 Optional In the Monitoring Extensions pane, click Collect VM statistics. To configure the extension, choose 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: 43). The name and password of the user that has the privileges required for connecting to the vcenter server or ESX server and retrieving information. 9 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. 10 When the installation completes successfully, the Monitoring Initialized Successfully dialog box appears. Click Add another Database or Finish to exit. NOTE: The Use this option to discover your SQL-Server instances link is for discovering and enabling several instances in one monitoring process. By searching and discovering the Instances on the network through an IP range, Host's or specific IP's or by importing from SQL Server predefined Regserv file. 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 ananticipate 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 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. 10
