Storage resource usage logs

This page explains how to view the Backup and DR Service storage resource utilization logs created by Cloud Logging for backup/recovery appliances. The storage resource utilization logs provide essential insights into the data protection activities performed by applications and virtual machines (VMs). These logs include detailed information about the amount of protected data.

Permissions and roles

You need the IAM permission roles/logging.viewer to view the storage resource utilization logs. The Logs Viewer role gives you read-only access to view storage resource utilization logs of all backup/recovery appliances in the specified project. For more information about the IAM permissions and roles that apply to storage resource utilization logs data, see Access control with IAM.

View storage resource utilization logs

You can view Backup and DR Service storage resource utilization logs in Cloud Logging by using the Google Cloud console and the Google Cloud CLI.

Console

In the Google Cloud console, you can use the Logs Explorer to retrieve the Backup and DR Service storage resource utilization log entries for your backup/recovery appliances:

  1. In the Google Cloud console, go to the Logging > Logs Explorer.
  2. Select an existing Cloud project.
  3. In the Query builder pane, select gcb_backup_storage_utilization from the Select Log name drop-down.

gcloud

The Google Cloud CLI provides a command-line interface to the Logging API. To read your log entries of backup/recovery appliances in a project, run the following command:

gcloud logging read "logName : projects/PROJECT_ID/logs/backupdr.googleapis.com%2Fgcb_backup_storage_utilization" --project=PROJECT_ID

Storage resource utilization log format

Backup and DR Service storage resource utilization log entries include the following fields:


Field
Description

Appliance name
The name of the appliance associated with the storage resource.

Storage type
The type of storage pool, for example, perf pool, onVault Pool, or primary pool.

Pool Name
The name of the pool.

Total capacity (GiB)
The total capacity of the storage pool. This isn't applicable for OnVault pools.

Used Capacity (GiB)
The consumption of the storage pool.

Appliance ID
The ID of the appliance associated with a storage resource.

Utilization %
The percentage of vDisk and pool volume consumed. This isn't applicable for the OnVault pool.

The following sample is an example log entry logged on a backup/recovery appliance appliance-test5-64573.

    {
      "insertId": "3302897_145859162970",
      "jsonPayload": {
        "appliance_id": "145859162970",
        "appliance_name": "appliance-test5-64573"
        "pool_name": "act_per_pool000",
        "storage_type": "perf",
        "total_capacity_in_gib": 4075.52,
        "used_capacity_in_gib": 163.84,
        "utilization_percentage": 4.020100502509347,
      },
      "resource": {

        }
      },
      "timestamp": "2024-03-12T03:03:02.170Z",
      "logName": "projects/project_ID/logs/backupdr.googleapis.com%2Fgcb_backup_storage_utilization",
      "receiveTimestamp": "2024-03-12T03:03:06.740899360Z"
    }

Sample queries

To view selected logs, you can write custom storage resource utilization queries in the query section

Use the following query to view all the storage resource utilization logs associated with backup/recovery appliances for a given PROJECT_ID:

    logName="projects/PROJECT_ID/logs/backupdr.googleapis.com%2Fgcb_backup_storage_utilization"

Use the following query for specific storage resource details that run for a specific resource.

    logName="projects/PROJECT_ID/logs/backupdr.googleapis.com%2Fgcb_backup_storage_utilization"
    jsonPayload.appliance_name="appliance_name"

Use the following query for storage resource details that run for applications for a specific pool.

    logName="projects/PROJECT_ID/logs/backupdr.googleapis.com%2Fgcb_backup_storage_utilization"
    jsonPayload.pool_name="pool_name"

Use the following query for specific storage types.

    logName="projects/PROJECT_ID/logs/backupdr.googleapis.com%2Fgcb_backup_storage_utilization"
    jsonPayload.storage_type=("storage_type")

Use the following query to find applications with utilization percentage < 50%.

    logName="projects/PROJECT_ID/logs/backupdr.googleapis.com%2Fgcb_backup_storage_utilization"
    jsonPayload.utilization_percentage < 50
