Configuring Multiple Instances for Monitoring using Silent Installation

To add multiple agents using the silent installation through a command line interface:
1
Navigate to Administration > Cartridges > Components for downloads.
2
Click the DB_SQL_Server_CLi_Installer name to download the installer.
The Download Message dialog box appears.
3
Review the details in this dialog box, and click Download.
The downloaded ZIP file contains the following files:
•
README.txt file
•
mssql_cli_installer.groovy — a groovy script file that runs the silent installation. This file should be copied to the <FMS_HOME>/bin directory.
•
silent_installer_input_template.csv — a template file that should serve as the basis for inserting contents into the input CSV file. This file can be copied to any folder of your choice, if the path indicated by the <csv_instances_file_name> parameter (see below) points to the selected path. For details about the contents of this file, see Contents of the Input CSV File .
•
MSSQLPermissionsCheck.sql — this file contains the SQL that the user should run on the monitored instance to check permissions needed for monitoring
•
MSSQLPermissionsGrant.sql — this file contains the SQL that the user should run on the monitored instance in order to grant the instance the required permissions for monitoring.
4
Extract the ZIP file to a directory of your choice.
5
Copy the mssql_cli_installer.groovy file to the <FMS_HOME>/bin directory.
6
Go to the command line and run the command: <FMS_HOME>/bin/fglcmd -srv <fms_host_name> -port <fms_url_port> -usr <fms_user_name> -pwd <fms_user_password> -cmd script:run -f mssql_cli_installer.groovy fglam_name <fglam_name> instances_file_name <csv_instances_file_name> lockbox_name <lockbox_name> lockbox_password <lockbox_password>
The descriptions of the flags and parameters in this command are as follows:
•
<FMS_HOME>: The Foglight Management Server installation directory.
•
<fms_host_name>: Name of the host where the Foglight Management Server is installed.
•
<fms_url_port>: The Foglight Management Server port.
•
<fms_user_name>: The user name used for connecting to the Foglight Management Server.
•
<fms_user_password>: The password of the specified user.
•
<fglam_name>: The name of the selected FglAM where new agents are to be added.
•
<csv_instances_file_name>: The full path and the name of the input CSV file.
•
<lockbox_name>: Optional — specifies the name of an existing lockbox to be used.
•
<lockbox_password>: Optional — the selected lockbox's password.
7
After the installation process completes, review the CSV files that are created in the same folder where the input file resides:
•
A file with the input file's name and _status suffix (for example: if the input file is named input, this file is named **input_new_-_**).
This file indicates the monitoring situation of all SQL Server instances listed in the input CSV file. If monitoring failed for one or more of the instances, the file specifies the error message.
The _status file includes the name of the monitored Foglight for SQL Server agent, the result of the monitoring validation process — MONITORED, FAILED, or AGENT EXISTS — and the error message, in case the agent creation failed.
 
* 
IMPORTANT: If all instances listed in the input CSV file passed the monitoring validation successfully, no additional file is created.
•
A file with input file's name and _new suffix (for example: if the input file is named input, this file is named input_status).
This file, which is only created if one or more instances failed the monitoring validation, contains all details about these instances.
Using this CSV file, the user only needs to fix the errors and re-run the script, this time by specifying this file as the input file, that is: the original filename with suffix _new. In the example used here, the new file should be named input_new_new.csv.

Contents of the Input CSV File

The input CSV file contains the following fields, which are used as columns in the resulting file:

Configuring the On Demand Data Port on the Agent Manager Concentrator

If a firewall is installed between the Management Server and the Agent Manager, a bidirectional On-Demand Data Port connection is not possible because On-Demand data requests require direct connection.

This issue can be resolved by creating an On-Demand Data Port on the concentrator — an Agent Manager instance that works similarly to an HTTP proxy. This On-Demand Data Port can be configured to accept On-Demand data requests from the Management Server and direct them to the Agent Manager instances (called downstream instances). For additional details about the concentrator, see Configuring an Agent Manager Instance as a Concentrator in the Agent Manager Installation Guide.

Figure 3. On-Demand Data Port connection with firewalls installed.

A concentrator agent, created specifically for Foglight for SQL Server, allows controlling the On-Demand Data Port so that the server is initialized (starts collecting data) when the agent starts, and stops when data retrieval by the agent ends. The agent, which the user creates manually, requires configuring the following parameters:

•
A list of the downstream hosts that are connected through the concentrator
•
The RMI port number

Each time the Foglight Management Server sends RMI request, the list of downstream hosts submitted by the concentrator agent is being searched, as follows:

•
Inclusion of the target RMI server host name within this list indicates that a FglAM concentrator exists, in which case a connection is made to the proxy RMI server.
•
If the list does not contain the target host name, the connection is made directly to the target On-Demand data port server.
To create the concentrator agent:
1
Go to Dashboards > Administration > Agents > Agent Status.
2
Click Create Agent.
3
Select the agent type DB_SQL_Server_Concentrator.
4
Enter a name of your choice.
5
Click Create.
6
After the creation process is completed successfully, click OK.
To edit the concentrator agent connection details:
1
Select the newly created concentrator agent.
2
Click Edit Properties.
3
Click Modify properties for this agent only.
4
Enter the number of the proxy On-Demand Data Port server port, or accept the default number.
5
Enter the concentrator Foglight Agent Manager host name (optional).
6
Click Edit to edit the list of downstream Agent Managers.
7
Click Add Row.
8
Enter the name of the requested Foglight Agent Manager host.
 
* 
IMPORTANT: When editing the properties of the Foglight Agent Manager concentrator (Dashboards > Administration > Agents > Agent Status), the name of the Foglight Agent Manager should be entered in the Downstream FglAMs section exactly as it appears in the topology, under Home > Agents > All agents > <Agent name> > RMI data > FglAM host property. The <Agent name> parameter refers to the Foglight for SQL Server agents that reside on the selected Foglight Agent Manager.
9
Repeat Step 7 to Step 8 as many times as required.
10
Click Save Changes.
11
Click Save at the lower right corner of the screen.
12
Click Back to Agent Status.
13
Select the newly created concentrator agent.
14
Click Activate.
15
Click OK to complete the process.

In an environment that includes a Foglight Agent Manager concentrator, when upgrading the environment where the concentrator does not contain any regular agents, the concentrator is not upgraded. Therefore, after the upgrade process takes place the Foglight Agent Manager concentrator has to be deployed manually.

 

 

Using Foglight for SQL Server

Foglight for SQL Server monitors the SQL Server database activity by connecting to and querying the SQL Server database. The agents provided monitor the SQL Server database system. The dashboards included with the cartridge provide a visual representation of the status of the major components of the SQL Server agents. They allow you to determine any potential bottleneck in database performance.
