If you have multiple metric filters that are associated with a log group, all the filters are applied to the log streams in that group. log, and cfn-wire. js or Java) in response to events. Objective: Set up a Cloudformation stack that takes a log group name as a parameter, and whenever new logs show up in that log group, they get sent to a Lambda function for processing, then to Kinesis Firehose, which then sends the log files to a bucket called foobarbaz. Choose the Test tab. CloudWatch Logs events are sent to Firehose in compressed gzip format. I'm wondering if there is an easy way to group the three log groups into just one group, this way it is much easier to follow my lambdas How to create AWS CloudWatch Subscription Filters for multiple Log Groups using CloudFormation.

However, the Sumo Logic apps may not be compatible with the custom format, and our out That’s all here, now we can move on to Lambda Promtail. This approach creates an extensible solution. The Target property type of AWS::Events::Rule has Input parameter:. If you use this property, nothing from the event text itself is passed to the target. We will need this physical id in the next section, when we create the CloudWatch Logs subscription filter. The function names are generated by CloudFormation and have the following format:. The CloudWatch Logs agent on Windows (SSM agent on Windows 2012R2 and Windows 2016 AMIs) only sends logs after it's started, so any logs that are generated before startup aren't sent.
