Create an Amazon Web Services account at http://aws.amazon.com and activate Amazon S3 on your account. Once your account is activated, create a bucket for log archives, and share write-only access to Papertrail for nightly uploads.
Create a new bucket for your log archives in your S3 account, using the information below. See Creating, configuring, and working with Amazon S3 buckets in the Amazon documentation for more information.
companyname-papertrail
. The name
should
consist of only lowercase letters, numbers, and hyphens. (more info).4b0a516d33d6b490d119301a4b16db3fa49a6b33bdc5135c2ab90e8184f6995f
with Write access
enabled for Objects. To set up permissions with IAM instead, see Define Sharing Policy with IAM.Changes can be made after the fact by selecting the bucket and choosing the Permissions tab.
Amazon also has instructions for editing bucket permissions.
If you followed the instructions above to grant permissions via the AWS Management Console, skip this step.
If you prefer defining a bucket policy to control access, here’s an example policy that permits Papertrail to upload archives:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "PapertrailLogArchive",
"Effect": "Allow",
"Principal": {
"AWS": [
"arn:aws:iam::719734659904:root"
]
},
"Action": [
"s3:DeleteObject",
"s3:PutObject"
],
"Resource": [
"arn:aws:s3:::bucket-name/papertrail/logs/*"
]
}
]
}
where bucket-name/papertrail/logs/
is the directory for Papertrail. The s3:DeleteObject
action isn’t strictly necessary – it’s only used to clean up the temporary test_file.txt
during initial configuration. (However, since s3:PutObject
also permits overwrites, denying s3:DeleteObject
doesn’t provide any significant protection.)
Under Settings > Archives, enable S3 archive copies and provide the S3 bucket name.
Papertrail will perform a test upload as part of saving the bucket name (and will then delete the test file). Note that a new bucket can sometimes take several hours to become available, due to DNS propagation delays. If it fails, wait two hours, and try again.
When archives are uploaded to the bucket, each file is named under the path (key prefix) provided to Papertrail, typically papertrail/logs/<xxx>
where <xxx>
is an ID. For example, an archive file for 3 PM UTC created on February 25, 2019 would be:
bucket-name/papertrail/logs/54321/dt=2019-02-25/2019-02-25-03.tsv.gz
Days are from midnight to midnight UTC.
Papertrail supports S3 rather than Glacier because:
Yes, Papertrail takes advantage of S3’s server-side encryption so that archived data is encrypted at rest using AES-256.
