delete all log streams of a log group using aws cli

Question

In order to delete a log stream from a log group using the CLI command , individual log stream names are required . Is there a way to delete all log streams belonging to a log group using a single command?

Answer 1

You can achieve this through using --query to target the results of describe-log-streams. This allows you to loop through and delete the results.

aws logs describe-log-streams --log-group-name $LOG_GROUP_NAME --query 'logStreams[*].logStreamName' --output table | awk '{print $2}' | grep -v ^$ | while read x; do aws logs delete-log-stream --log-group-name $LOG_GROUP_NAME --log-stream-name $x; done

You can use --query to target all or specific groups or streams.

Delete streams from a specific month

aws logs describe-log-streams --log-group-name $LOG_GROUP --query 'logStreams[?starts_with(logStreamName,`2017/07`)].logStreamName' --output table | awk '{print $2}' | grep -v ^$ | while read x; do aws logs delete-log-stream --log-group-name $LOG_GROUP --log-stream-name $x; done

Delete All log groups - Warning, it deletes EVERYTHING!

aws logs describe-log-groups --query 'logGroups[*].logGroupName' --output table | awk '{print $2}' | grep -v ^$ | while read x; do aws logs delete-log-group --log-group-name $x; done

Clearing specific log groups

aws logs describe-log-groups --query 'logGroups[?starts_with(logGroupName,`$LOG_GROUP_NAME`)].logGroupName' --output table | awk '{print $2}' | grep -v ^$ | while read x; do aws logs delete-log-group --log-group-name $x; done
