I just created a new AWS kinesis stream and have it set up to receive data I am pulling in a lambda function. Theres is some data in my cloud watch logs that came in before I had my stream set up. Is there a way to get manually send this to kinesis?
There are ways as shown in this answer to export CloudWatch logs as JSON/txt/etc. afterwhich you could design some sort of script to iterate through those logs and put them into your Kinesis stream

I have been Stocked on how to send Lambda logs(Prints) directly to Amazon Kinesis Data Stream. I have Found the way to send Logs from Cloud watch but I would like to send every single prints to kinesis data streams. I have a doubt if I send data from cloud watch does it stream real time prints records to kinesis or not? On this case I would like to use lambda as producer and through the kinesis data S3 as a consumer .
below I have attached a flow work of my conditions.
You can also check the lambda extensions, which helps into direct ingestion of the logs to custom destinations. Its helpful incase you want to avoid cloudwatch costs

You have to create CouldWatch Subscription filter for the Lambda's log stream you want to save to S3. So you would do:
CW Logs subscription ---> Firehose ---> S3
I know its is possible to stream CloudWatch Logs Data to Amazon Elasticsearch Service. It is documented here, But is it possible to stream the logs data to a custom AWS Glue Job, or to an EMR Job?
The way streaming of CloudWatch Logs (CWLs) to ElasticSearch (ES) works, is that AWS creates a lambda function for you. So CWLs will stream to lambda first, and the lambda will then upload the log events to ES.
For Glue, you don't need lambda function, as glue can get its streaming data from kinesis streams. So you would have to setup CWL subscription to kinesis stream. The stream would be used as a source in a streaming Glue job.
For EMR you could also just stream log events from CWL to kinesis in the same way as for Glue. But to read the stream data in EMR, you would probably have to use EMR Input Connector for Kinesis.
I have a CloudWatch Log Group, this log group continuously receives logging information from my AWS services.
I want to extract some of the logging information from this log-group and want to store that data into S3 in some format (CSV, PARQUET).
I will then use Athena to query this logging data.
I want some sort of automatic mechanism to send these logs continuously to S3.
Can anyone suggest solution for this?
It looks like Athena is able to communicate directly with cloudwatch as shown here. Not sure how performant this is and how costly this turns out.
The other option is to configure Cloudwatch to send data to Firehose via Subscriptions which then dumps it to S3.
There is a group of AWS CloudWatch Logs, inside which there are several threads. As far as I understand it, each thread is a log coming from a separate server or container.
CloudWatch Log streams
I put the whole group of logs in Kinesis Firehose to deliver them to S3 Bucket. But inside Kinesis Firehose, all the logs are merged into one. How can I get these logs to the S3 storage so that each thread has its own directory?
I found a solution:
1) I modified every log in Kinesis Firehose using the Lambda function. I added an identifier to the end of the log line. And then it looks like this:
Modified logs
2) I created a Lambda function with a trigger that works every time logs are written to s3 bucket. And in this function, I distribute logs to the folders I need based on the information I added to the logs earlier. I will not give the code of this lambda function. I've described the general approach and I think those who need it can figure it out.
I am new to AWS, I want to move my aws real time cloudwatch stream logs to Redshift Table.I am thinking like first I want to move my cloudwatch stream logs to lambda funtion from there to Redshift. If you have any idea how to get those cloudwatch logs to lambda function, Please let me know. I dont any idea on it. I went through lot of docs but I didnot find proper lambda function to get stream logs from cloudwatch.
You should add subscription to your CloudWatch logs to a Kinesis/ Firehose.
