VM Instances page in the GCP VM Instances view
An instance is a virtual machine that is used for running the applications in the Google Cloud environment. The VM Instances page in the GCP VM Instances view provides an overview of all available VM instances. You can also drill down into the VM instance to view capacity and decision support metrics at the instance level.
To access this page, in the Views tab, select Views > Cloud > GCP > VM Instances. By default, the VM Instances page is displayed.
VM Instances table
The VM Instances table lists the following information for each VM instance. By default, some columns are hidden. You can show or hide columns using the action menu
that is located next to the VM instances table title. You can sort columns in tables alphabetically, or by size. For more information, see Sorting a table in Views.
VM Instances table: Description of columns

| File System [GB] | Total size of the file systems configured in this VM. | Last value | TOTAL_FS_SIZE |
| File System Util [%] | Percentage of maximum value of utilization of all the file systems configured in this instance. | 95th percentile | TOTAL_FS_UTIL |
| File System Trend [%] | The daily growth rate of the file system. | Trend | Computed using TOTAL_FS_UTIL |
| File System Days to Saturation | The projected amount of time before the file system runs out of available storage capacity. This metric is displayed only if file system utilization is available for a minimum of five days.
| Computed by the Indicator Service using total capacity and 95th utilization of file system. | IND_DAYS_TO_SATURATION[STORAGE] |
| I/O Rate [MB/s] | 95th percentile value of the disk input/output rate measured in megabytes per second. | 95th percentile | DISK_TRANSFER_RATE |
| Network Rate [Mbit/s] | 95th percentile value of the network input/output rate measured in megabits per second. | 95th Percentile | NET_BIT_RATE |

Detailed information about a VM instance
After you click on the VM instance in the Instance Name column, the details for that instance are displayed in the VM Instance Details page. The VM Instance Details page displays the following information:
| Section or Panel | Description |
|---|---|
| General details section | General details, such as VM instance name and type are displayed. The type is Virtual Machine - Google Cloud. |
| Related Information panel | Clicking the links in the Related Information panel displays the other information related to the selected instance.
|
| Summary tab | The Summary tab, that is displayed by default, displays CPU, Memory, and Storage utilization details for the selected instance in a horizontal summary table, as well as charts. Core metrics for the selected entity are displayed as analysis charts, depending on available data. At the bottom of each chart is a link that takes you to the Data Explorer view for the specific resource type, and displays charts and information for a larger set of metrics. To return to this page, click the arrow |
| Configuration Details tab | The Configuration Details tab displays the configuration matrix for the selected instance. |
| File Systems | The File Systems tab displays information for all file systems of the instance. For more information, see view_file_system. |
File Systems of a VM instance
The File Systems tab in the VM Instance Details page displays the following information for all file systems of the selected instance.
| Column | Description | Statistical Type | Metrics |
|---|---|---|---|
| File System | Name of the file system of this instance. | Last Value | SUBOBJNAME |
| File System Util [%] | Percentage of total file system utilization of a partition by the selected instance. | 95th percentile | BYFS_USED_SPACE_PCT |
| File System Trend [%] | The daily growth rate of the file system. | Trend | Computed using BYFS_USED_SPACE_PCT trend |
| Days to Saturation | The projected amount of time before the file system runs out of available storage capacity. A number of days to saturation is reported here. | Computed by the Indicator Service using total capacity and 95th utilization of file system | Computed using BYFS_USED_SPACE_PCT trend |
