If a file is changed, created, or deleted, the path to the file prints to the console.

The Reload Lists Using Data File task is currently supported for this feature. You will also be able to configure file watchers in that folder triggered by the event notifications on the bucket. For example, you can drop files into the bucket from the LabKey interface, and have them appear in the S3 bucket, or vice versa. Once cloud storage with queue notifications is configured, and enabled in your folder, you will be able to create a Files web part in the folder that 'surfaces' the S3 location. When in a state that cannot be validated, notifications will still be sent, but this is an interaction to keep in mind if you encounter problems defining a new one. If you have existing notifications configured when you add a new one for your LabKey file watcher, you will not be able to save or edit new ones until you resolve the configuration of the prior ones. If you have multiple event notifications defined on your queue, note that they will be validated as a group. LabKey is 'monitoring' this queue via the Storage Config, so now you will be able to enable file watchers on those locations. Now when files in your bucket's Prefix location have the Suffix you defined, an event notification will be triggered on the queue specified. Enter SQS queue ARN to enter it directly.

Choose from your SQS Queues to use a dropdown selector or.

Suffix: A suffix for the files that should trigger notifications, such as '.list.tsv' if you want to look for files like '' and '' in the container specified in the prefix.

This prefix should either match, or be a subdirectory of, the Location to Watch you will set in your file watcher. In this case the prefix would be something like '/cloud_storage/lk_2483/watched/'. For example, you might be using a 'cloud_storage' main directory and then employ a LabKey directory prefix like 'lk_' for each LabKey folder, then a 'watched' subdirectory there.

Prefix: This is typically the directory path within the bucket, and will depend on how you organize your buckets.

Only objects with both the specified prefix and suffix will trigger notifications. MyFileDrop) and provide optional prefixes and suffixes to define which bucket contents should trigger notifications.

Under General configuration, name the event (i.e.

On the bucket's Properties tab, click Create Event Notification.

Take note of the region (like 'us-west-2') for your bucket. If you have not already set up your bucket, follow the instructions in this topic: Configure Cloud Storage You will be configuring an SQS Queue that LabKey Server can 'watch' for notifications, then setting up event notifications on the bucket that will add to that queue when certain files are added to certain bucket locations.ДЇirst, you must configure a Simple Queue Service within AWS to which your bucket will be able to post notifications.

Include SQS Queue URL in Storage Config.

This topic describes how to configure the bucket and queue on AWS to support this. If you plan to use file watchers for files uploaded to your bucket, you need to supply an SQS Queue URL in your Storage Config on LabKey Server. Also available as an Add-on to the Starter Edition.
