EC2 Instances table
The EC2 Instances table lists the following information for each EC2 instance. By default, some columns are hidden. You can show or hide columns by using the action menu
that is located next to the EC2 instances table title. You can sort columns in tables alphabetically, or by size. For more information, see Sorting-a-table-in-Views.
Column | Description | Statistical type | Metrics |
|---|---|---|---|
Instance Name | Name of the AWS instance. Clicking one of the instances in this column of the summary view takes you to the EC2 Instances details view. | Last Value | NAME |
Availability Zone | Name of the availability zone to which this instance belongs to. | Last Value | AVAILABILITY_ZONE |
Requested Instance Type | Instance type specifies the required resources to run this instance. | Last Value | REQUESTED_INSTANCE_TYPE |
CPU [cores] | Number of virtual CPUs that are configured for the virtual machine | Last Value | CPU_NUM |
CPU Util [%] | Percentage of total CPU utilized by the selected instance. | 95th percentile | CPU_UTIL |
CPU Trend [%] | Daily growth rate of CPU utilization of the instance. | Trend | Computed using CPU_UTILMHZ |
CPU Days to Saturation | Projected amount of time before CPU runs out of available capacity. A number of days to saturation is reported here. | Computed using total capacity and 95th utilization of CPU | IND_DAYS_TO_SATURATION[CPU] |
Memory [GB] | Total physical memory capacity in the selected instance, measured in GB. | Last value | TOTAL_REAL_MEM |
Real MemoryUtil[%] | Percentage of real physical memory utilized by the instance. This metric excludes the memory assigned to the file system cache and it is displayed only if the additional monitoring scripts are scheduled to run on the selected instance. | 95th percentile | MEM_REAL_UTIL |
Memory Trend [%] | Daily growth rate of memory utilization of the instance. This metric is displayed only if real memory utilization is available. | Trend | Computed using MEM_REAL_UTIL |
Memory Days to Saturation | Projected amount of time before the memory runs out of available capacity. This metric is displayed only if real memory utilization is available for a minimum of five days. | Computed using total capacity and 95th utilization Memory | IND_DAYS_TO_SATURATION[MEMORY] |
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 [%] | 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 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 |
