Monitoring Storage Gateway

This topic describes how to monitor Storage Gateway file system upload activity, system health, and storage usage. The topic also describes how to view system notifications and also how to receive these notifications in email.

Important

Monitoring file system activity in the Storage Gateway management console consumes system resources. Monitoring file system activity is not recommended when Storage Gateway is under high load.

Monitoring Upload Activity

When you upload a file to a file system, you can view the status of the upload activity. The Activity tab shows the ongoing and pending upload activity in a file system.

Monitoring System Health Status

You can monitor the overall system health status using System Status on the right side of the management console.

The Storage Gateway performs an automated "health check" on the system to monitor the status of the following:

  • Storage Gateway resources and services
  • Local storage, file system cache, metadata storage, and log storage

Depending on the Storage Gateway health analysis, the following status is displayed in System Status:

  • Healthy
  • Unhealthy

System Status also displays information about the following:

  • Any system warnings or errors.
  • Local I/O Mode displays one of the following values depending on the local disk usage:
    • Normal

      The available disk space is greater than 10 GB in Storage Gateway. You can upload files in Storage Gateway and upload them to your Oracle Cloud Infrastructure tenancy.

    • Rejecting I/O

      The available disk space is less than 10 GB in Storage Gateway. Storage Gateway runs in protection mode and does not allow any writes to its local disk. All read operations work normally. All Storage Gateway metadata operations fail except for deletions and truncation.

      To return to Normal mode, you must wait until all the ongoing upload activities are complete and the files are removed from the read cache.

  • Throughput

    The approximate upload throughput to Object Storage. If there is no recent activity, Throughput shows Idle.

  • Available Read Cache

    For optimal performance, reliability, and fault tolerance, follow the guidelines for configuring cache storage . See Configuring Local Storage for File Systems and Cache for details.

  • Pending Uploads

    The number of files or directories (for all file systems) that are pending upload to Object Storage. If Pending Uploads is 0 (zero), all files and directories have been uploaded.

Monitoring Storage Usage

You can track the storage usage and availability.

Viewing System Notifications

The System Notifications tab allows you to view the system notifications and track the overall system performance.

Configuring Email Notification

You can configuration Storage Gateway to notify you about system health by email.
