These queries can be grouped in folders based on your application needs and are visible to anyone who has access to the CloudWatch in AWS Console. Saved QueriesĬloudWatch Insights also enables the saving of Queries for later use. Given a correlation id or a unique id passed across applications, you can filter the data across multiple applications and see the end-to-end flow of events. It is handy in distributed applications where multiple applications are responsible for handling a business use case. Log Insights also supports querying across multiple log groups. You can set it to show just the properties that are important to you in the collapsed view. It also supports formatting the queried log events in custom formats. There can be a delay between events showing up in Log Groups and their appearing in CloudWatch Log Insights. The query syntax supports custom functions and operations and is not limited to arithmetic or regex expressions. It allows to interactively search and analyze log data and supports a custom query language. Log InsightsĬloudWatch Log Insights provides richer capabilities to interact with log events. Message = $'Get Weather Forecast called for city → selects all log events that have a count property greater than 10 with the cityName property as Brisbane. Var logGroupExists = (l => l.LogGroupName = logGroupName) Īwait logClient.CreateLogGroupAsync(new CreateLogGroupRequest(logGroupName)) Īwait logClient.CreateLogStreamAsync(new CreateLogStreamRequest(logGroupName, logStreamName)) Īwait logClient.PutLogEventsAsync(new PutLogEventsRequest() DescribeLogGroupsAsync(new DescribeLogGroupsRequest() Var logStreamName = ('yyyyMMddHHmmssfff') Var logGroupName = '/aws/weather-forecast-app' var logClient = new AmazonCloudWatchLogsClient() The log events are written into that log stream, log group combination.

The below code creates a log group if it does not already exist and adds a log stream to it. It provides capabilities to create log groups, log streams, and log events. The AWSSDK.CloudWatchLogs NuGet package provides the AmazonCloudWatchLogsClient to interact with CloudWatch logs. I prefer using Serilog for easy integration and out-of-the-box structured logging support. There are different ways to integrate with the CloudWatch service from a. Log groups → group of log streams that share retention, monitoring, and access control settings.Log streams → sequence of log events that share the same source.Log events → record of some activity recorded by the app or resource being monitored.The main concepts that you’ll keep coming across when using CloudWatch Logs are Log events, Log streams, and Log groups.

#LOGS ON AWS HOW TO#

We will learn how to write logs into CloudWatch, filter the logs, some good practices when logging, learn about Log Analytics, and see how we can filter and view logs across multiple applications. In this article, let’s learn how to use Amazon CloudWatch when building.

#LOGS ON AWS ARCHIVE#

When building applications on AWS, CloudWatch provides a centralized, highly scalable service that your applications can read and write logs.ĬloudWatch allows to view, search, filter, or archive logs easily. Logging is an essential aspect of application development.
