SSIS: Logging Providers

Introduction

This tutorial explores the concept of logging providers in SQL Server Integration Services (SSIS). Logging is essential for monitoring and troubleshooting SSIS package execution, and logging providers allow you to capture and store relevant information about package runs.

Logging Providers in SSIS

Syntax

Logging providers in SSIS are configured through the SSIS package's properties. You can specify various settings, including the log provider type, connection strings, and logging options.

Example

1. Open your SSIS package in SQL Server Data Tools (SSDT).
2. Right-click on the background of the control flow or data flow and select "Logging."
3. Add a new log provider, choose the provider type (e.g., SQL Server), and configure the connection string and logging options.

Output

The output is a log of SSIS package execution, which may include details such as start time, end time, execution results, and error messages.

Explanation

• Log Provider Types: SSIS supports various log provider types, including SQL Server, XML file, Windows Event Log, and others.
• Connection Strings: Connection strings are used to specify the location where the log information will be stored.
• Logging Options: Configure logging options, such as events to log (e.g., OnPreExecute, OnPostExecute) and the level of detail.

Common SSIS Logging Providers

SQL Server Logging

• Syntax:

  Configured by specifying the SQL Server log provider and providing connection details.

• Example:

  ConnectionString=Data Source=YourServer;Initial Catalog=YourDatabase;Integrated Security=True;
  

• Use:

  Suitable for centralizing log information in a SQL Server database for easy querying and reporting.

XML File Logging

• Syntax:

  Configured by specifying the XML file log provider and providing the file path.

• Example:

  ConnectionString=C:\Logs\SSISLog.xml;
  

• Use:

  Useful for storing log information in a structured format for archival or external analysis.

Windows Event Log

• Syntax:

  Configured by specifying the Windows Event Log provider. No additional connection string is required.

• Use:

  Ideal for logging events directly to the Windows Event Log for centralized system monitoring.

Important Points

1. Performance Impact: Consider the performance impact of logging, especially in high-volume data scenarios.
2. Sensitive Information: Be cautious when logging sensitive information, and use secure storage options.
3. Log Retention: Establish log retention policies to manage the size and duration of log information.

Summary

Logging providers in SSIS play a crucial role in capturing and storing information about package execution. By configuring the appropriate log provider and settings, you can effectively monitor, troubleshoot, and analyze the performance of SSIS packages.
