CloudWatch Log Retention Period

[stack72]

Hi

When using the following code:

_, err := conn.CreateLogGroup(&cloudwatchlogs.CreateLogGroupInput{
    LogGroupName: aws.String("test),
})
if err != nil {
    return fmt.Errorf("Creating CloudWatch Log Group failed: %s", err)
}

putInput := cloudwatchlogs.PutRetentionPolicyInput{
    LogGroupName:    aws.String("test"),
    RetentionInDays: aws.Int64(7),
}
log.Printf("[DEBUG] Setting retention for CloudWatch Log Group: %q: %s", name, putInput)
_, err = conn.PutRetentionPolicy(&putInput)


input := &cloudwatchlogs.DescribeLogGroupsInput{
        LogGroupNamePrefix: aws.String("test""),
    }
resp, err := conn.DescribeLogGroups(input)
if err != nil {
    return nil, err
}

The response from the DescribeLogGroups doesn't give me the correct value (of 7) for the retention period. I need to call the Describe func a second time to get that value. It obviously takes some time for the retention period to be added to the LogGroup, but PutRetentionPolicy doesn't return me anything that allows me to wait for the state to be updated

Any suggestions here?

Hello @stack72, thank you for reaching out to us. It would seem if the request succeeds, then could you not wait the specified time? Let me know what concerns you have with this idea

Hi @xibz

My apologies I wasn;t clear here. I mean that when i query the DescribeLogGroups that the value of 7 is not returned for RetentionInDays. that value of 7 is only available after a short (indeterminate) amount of time. My thought here is that the LogGroup takes some time for the change to be applied. But how can i know when the LogGroup has been updated?

@stack72, what is it that you are trying to do with the RetentionInDays? I imagine you are looking to check the state of the LogGroup, like PENDING, that way you don't have to keep track of all the numbers. Let me know if this isn't the reasoning!

@xibz

Thanks for the repo here. I will just check the state of the LogGroup to make sure that it isn't in a pending state. If it doesn't help then I will re-comment

Thanks

@stack72 - Unfortunately, there is no state associated with the LogGroups. I was curious if that was more of what you were trying to do. Sorry if I wasn't clear

[stack72]

yeah that was what i was trying to achieve. How do I know when a retention period has been added to the LogGroup? It's not an immediate thing

[xibz]

Okay, I am asking Cloudwatch if there is a way to do this. It seems the SDKs do not allow for this. So, once they get back to me, I'll update you!

[stack72]

thanks so much for all the help here @xibz :)

Hi @stack72 we are working with the CloudWatch Logs team to get a better understanding of what the expected functionality of this issue is. We'll update this issue once we have more information from the service team.

[stack72]

Awesome :) Thanks!

@stack72 - CloudWatch Logs states it happens immediately. Are you doing something that has unexpected output?

[stack72]

Hi @xibz

I am trying to get this working now. If the Cloudwatch Logs say it works as so then I will find the fix on my side. I will close the issue until it has been proven otherwise

Thanks for all the work here
