Getting Started With Serilog and Azure Data Explorer
Introduction
Serilog is an open-source logging framework used to collect and structure log data. It simplifies the process of creating log events and makes it easier to send log data to a variety of destinations, including Azure Data Explorer. By combining Serilog with Azure Data Explorer, developers can easily collect, store and analyze log data.Benefits Of Using Serilog With Azure Data Explorer
Using Serilog with Azure Data Explorer provides a number of benefits for developers. First, it makes it easier to structure and collect log events, as well as streamline the process of sending log data to Azure Data Explorer.Second, it provides powerful querying capabilities, allowing developers to quickly search through log data and identify patterns or exceptions. This can be especially useful for troubleshooting and performance tuning.
Third, it enables developers to analyze log data at scale with Azure Data Explorer. This can help them gain valuable insights into application and system performance, as well as identify potential issues or opportunities for improvement.
Prerequisites
Before getting started, there are a few prerequisites that must be met. First, developers will need to have Visual Studio installed. They will also need an Azure subscription, as well as the Azure Data Explorer .NET SDK.Creating A Serilog Logger
Once the prerequisites are met, developers can begin setting up their Serilog logger. This can be done by adding the following code to the startup class:Log.Logger = new LoggerConfiguration() .MinimumLevel.Verbose() .WriteTo.AzureDataExplorer(“YOUR_CONNECTION_STRING”) .CreateLogger();This code creates a new LoggerConfiguration object and sets it to the Log.Logger property. It then sets the minimum log level to Verbose, which will capture all log events. Finally, it configures the logger to send log data to Azure Data Explorer using the provided connection string.
Creating Log Events
Once the logger has been set up, developers can begin creating log events. This can be done using the Log.Information() method, as shown below:Log.Information(“This is an informational log event.”);
This will create a new log event with the provided message. Developers can also use the Log.Warning(), Log.Error(), and Log.Fatal() methods to create log events with different levels.
Querying Log Data
Once log events have been created, developers can then query log data using Azure Data Explorer. This can be done using the Kusto Query Language (KQL), which is the language used by Azure Data Explorer to query data.For example, developers can query log data by log level using the following query:
logs | where Level == “Error”This query will return all log events with a log level of “Error”. Developers can also use the KQL to query log data by date and time, as well as other criteria.
Conclusion
Serilog is an open-source logging framework that makes it easy to collect and structure log data. By combining Serilog with Azure Data Explorer, developers can easily collect, store and analyze log data. This can help them gain valuable insights into application and system performance, as well as identify potential issues or opportunities for improvement.
