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 menuthat is located next to the VM instances table title. You can sort columns in tables alphabetically, or by size. For more information, see Managing charts and tables in Views.

CPU Trend [%]The daily growth rate of CPU utilization of the VM instance.TrendComputed using CPU_UTIL
CPU Days to Saturation

The projected amount of time before CPU runs out of available capacity.

  • It displays a number of days to saturation.
  • If the days to saturation value is 91 days or beyond, this field displays Not saturated.
  • If the CPU is already saturated, it displays Saturated.

Computed by the Indicator Service using total capacity and 95th utilization of CPU.

IND_DAYS_TO_SATURATION[CPU]


Memory [GB]Total physical memory capacity of the selected instance, measured in GB.Last valueTOTAL_REAL_MEM

Percentage of cache memory utilized by the instance.

This metric is available only when additional monitoring scripts are scheduled to run on this instance.

95th percentileMEM_UTIL_CACHED
Memory Trend [%]Daily growth rate of memory utilization of the instance. This metric is displayed only if real memory utilization is available.TrendComputed using MEM_REAL_UTIL or MEM_UTIL
Memory Days to Saturation

The projected amount of time before the memory runs out of available capacity. This metric is displayed only if real memory utilization or memory utilization is available for a minimum of five days.

  • It displays a number of days to saturation.
  • If the days to saturation value is 91 days or beyond, this field displays Not saturated.
  • If the memory is already saturated, it displays Saturated.

File System Trend [%]The daily growth rate of the file system.TrendComputed 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.

  • It displays a number of days to saturation.
  • If the days to saturation value is 91 days or beyond, this field displays Not saturated.
  • If the memory is already saturated, it displays Saturated.

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 PanelDescription
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. 

  • Disk Profile: Displays the Disk Profile tab of the data explorer view for this instance.

  • Network Profile: Displays the Network Profile tab of the data explorer view for this instance.

  • Virtual Node: Displays the server details for the selected instance.

  • Thresholds: Clicking on the link cross-launches to the Capacity Optimization console and take you to the Thresholds page for the selected instance. For more information, see Configuring and managing thresholds for metrics and indicators.

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 icon on the top-right side in the Data Explorer tab.

Important

The data displayed in Data Explorer view charts for any resource part of this view category, is based on the time filter that is applied to the primary view in this tab. You can select Advanced time periods (other than default/basic) from the Data Explorer view for the selected resource, to view charts over a different time resolution.

Configuration Details tabThe 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.
