Object storage logs
Summary: View Object Storage bucket logs in the Neon Console: S3 request logs (GET, PUT, DELETE, and more) and Console/API bucket and object changes, with levels derived from HTTP status. Covers scope_name values and common patterns that look like a problem but aren't.
Object storage logs
Section titled “Object storage logs”View, search, and download logs for a bucket
Every S3 request against a bucket streams a log line to the Neon Console, along with a line for any bucket or object change made through the Console or Neon API (creating a bucket, deleting a bucket, deleting an object or prefix):
service_name: neon-storage/my-bucket
scope_name: neon.storage.s3.put
severity_text: INFO
body: {
"operation": "PUT",
"object_key": "path/to/object.parquet",
"http_status": 200,
"bytes": 4096,
"duration_ms": 9.5,
"request_id": "req-777",
"remote_ip": "203.0.113.9"
}View logs
Section titled “View logs”Bucket logs live on the branch's Monitoring page, in the Storage tab. To jump straight to one bucket's logs, open the bucket list, open that bucket's menu, and select View logs. Or go to Monitoring and open the Storage tab to see every bucket's logs together.
Expand a row to see its full context: timestamp, severity, entity_type (storage), scope_name, and service_name (neon-storage/<bucket>). The message body carries per-request detail: operation (the HTTP method), object_key, http_status, bytes, duration_ms, request_id, and remote_ip. access_key_id is included for authenticated requests and omitted entirely for anonymous reads against a public_read bucket, which is expected, not a sign of broken auth.
scope_name identifies what generated the line:
neon.storage.s3.<method>(get,put,delete,head,post): an S3 API request, named for its HTTP method rather than the semantic S3 operation. Multipart upload calls (UploadPart,CompleteMultipartUpload,AbortMultipartUpload) also surface under their HTTP method, not a dedicated multipart scope.neon.storage.api.<operation>(create_bucket,delete_bucket,delete_object,delete_prefix): a bucket or object change made through the Console or Neon API, not an S3 client. These appear in the same stream as S3 traffic, distinguished only by thisapivss3segment.
Log levels
Section titled “Log levels”A bucket's log level comes from the HTTP status code of the request, not from anything the client sets:
| Level | HTTP status |
|---|---|
INFO |
Everything else (successful requests) |
WARN |
4xx, plus 501 Not Implemented for unsupported operations |
ERROR |
Other 5xx responses |
DEBUG, NOTICE, and FATAL also appear as filters in the log viewer but aren't currently emitted by Object Storage; they're part of the console's shared log-level set.
Common log entries
Section titled “Common log entries”Most of what shows up here is routine S3 traffic. A few entries look worse than they are, and one common request type doesn't show up at all.
Seeing 403 or 404 lines? They're expected client-side errors, not incidents. Wrong or revoked credentials, a missing scope, or a bucket-scoped credential used from the wrong branch all return a 403 and log at WARN, same as any other 4xx. See Authentication errors for the specific error codes and fixes.
Seeing 503 SlowDown logged as ERROR? It's a healthy rate limit, not a server failure. SlowDown is a rate-limit signal returned when a request exceeds the per-IP or per-tenant limit; the storage service is otherwise healthy. It logs at ERROR only because the level is derived purely from the 5xx status code. Treat it as a signal to back off and retry, not an outage. See Connection and performance errors.
Calling ListBuckets or hitting the bucket list root? You won't find it here. Bucketless requests are deliberately excluded from the log stream, since there's no single bucket to attribute them to. If you're looking for that traffic, it isn't missing: it was never exported.
Seeing a 501 for an operation you expected to work? It's an unsupported operation, not a client error, even though it logs at WARN. Calls like PutBucketAcl, PutBucketPolicy, or PutBucketNotificationConfiguration return 501 Not Implemented because Neon Object Storage doesn't support them, not because you did anything wrong. See Not supported for the full list.
Filter, search, and retention
Section titled “Filter, search, and retention”For details on filtering by level or service name, searching log bodies, live tail, downloading logs, and the 3-day retention window, see Monitor logs.
You can also read storage logs from the terminal with neon logs query, scoped with --source storage:
neon logs query --source storage --since 1hRelated docs (Guides)
