To configure Log Manager for AWS S3, you must perform the tasks outlined in this document.
Before you set up S3 collection, you must log into the AWS console and create an IAM policy and role to provide Alert Logic with cross-account access to your AWS account.
Policy creation requires a policy document. Download and open this policy document, and then replace <S3BUCKET_NAME> with the name of the S3 bucket.
To create a cross-account access role:
- In the AWS Console, click IAM, located under Security, Identity & Compliance.
- From the IAM Management Console, click Policies, and then click Create Policy.
- Click the JSON tab.
- Copy and paste the contents of your policy document into the JSON window.
- Click Review policy.
- On the Review Policy page, type a Policy Name and Description for the policy.
- Click Create policy.
- From the IAM Management Console, click Roles, and then click Create role.
- On the Create role page, click Another AWS account.
- Enter the following information for Alert Logic:
- Account ID—Type 239734009475
- Select Require external ID.
- External ID—Use your Alert Logic Customer ID. To find your Customer ID, in the Alert Logic console, click Settings () > Support Information.
- Require MFA—make sure the option is not selected.
- Click Next: Permissions.
- Select the policy you created above, and then click Next: Review.
- Type a Role Name and Role description, and then click Create Role.
- In the list of IAM roles, click the name of the role you created, and then note the Role ARN value, which you will need when you create the AWS credentials in the Log Manager console.

- If the lengths of your log messages are consistent, select Each log message spans a fixed number of lines and then type the number of lines in Number of lines,.
- If the lengths of your log messages are not consistent, select Each log message follows a known pattern, select the appropriate Pattern application, type the Pattern that takes place in the log message, and then select Regular expression to use a Perl Compatible Regular Expression (PCRE).
Select a Timestamp Rule option:
- To use the timestamp from the collector, select Set message time as collect time.
- To use an existing timestamp, select Parse times from messages using a pre-defined timestamp format, and then select a format from Format a date string.
