loggroup-lambda-connector: connect existing log groups? about sumologic-aws-lambda

[himanshu219]

Here is the documentation https://help.sumologic.com/Send-Data/Collect-from-Other-Data-Sources/Auto-Subscribe_AWS_Log_Groups_to_a_Lambda_Function. See Step 5. Use the function to auto-subscribe existing log groups

If you know the exact name then you can modify the function's handler and directly invoke
subscribeToLambda(logGroupName, env.LAMBDA_ARN, errorHandler)
if you know the regex and you have multiple log group function that will require fetching loggroup names using describeLogGroups api (https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/CloudWatchLogs.html#describeLogGroups-property) and filtering the loggroups.
Also you can request for features in our aha portal (https://ideas.sumologic.com/ideas).You can also add your use case , upvote to increase its visibility.

@mwarkentin : just curious, do you have a lot of existing log groups? You can manually subscribe a log group from the console to an existing function as well

[mwarkentin]

Yes, we have a bunch of log groups. I ended up scripting a little shell script w/ the cli to subscribe our existing groups:

log_groups=$(aws logs describe-log-groups --log-group-name-prefix "${lg_prefix}" --profile ${profiles[${env}]} --query "logGroups[].logGroupName" --output text)
for lg in ${log_groups} ; do
  echo "Subscribing ${arns[${env}]} to ${lg}..."
  aws logs put-subscription-filter --log-group-name "${lg}" --filter-name "${env}-sumologic-cloudwatch" --filter-pattern "" --destination-arn "${arns[${env}]}" --profile ${profiles[${env}]}
done

The function now supports existing log groups.

@himanshu219 Thanks, I assume that's this change here: #57

Are there any details around how this works / how to use it?
