Description |
Measurement Unit |
Interpretation |
| Cpu_used |
Indicates the percentage of allocated CPU consumed by this instance. |
Percent |
A high value for this measure indicates that an instance is utilizing CPU excessively - this could be because of one/more resource-intensive processes executing on that instance.
Compare the value of this measure across instances to identify the CPU-intensive instances. |
| Network_in |
Indicates the rate of incoming network traffic i.e., the rate at which the bytes are received by all the network interfaces connected to this instance.
|
KB/Sec |
Compare the values of these measures across instances to quickly identify the instance that is utilizing the network bandwidth excessively. |
| Network_out |
Indicates the volume of outgoing network traffic i.e., the rate at which the bytes are transferred from all the network interfaces connected to this instance.
|
KB/Sec |
| Disk_reads |
Indicates the rate at which data is read from the disks of this instance. |
KB/Sec |
These measures are good indicators of the level of disk I/O activity on an instance. By comparing the values of these measures across instances, you can accurately determine which instance is performing I/O-intensive operations. |
| Disk_writes |
Indicates the rate at which data is written to the disks of this instance. |
KB/Sec |
| Disk_read_op |
Indicates the rate at which disk read operations are performed on this instance. |
Operations/Sec |
These measures are good indicators of the level of disk I/O activity on an instance. By comparing the values of these measures across instances, you can accurately determine which instance is performing I/O-intensive operations. |
| Disk_write_op |
Indicates the rate at which disk write operations were performed on this instance. |
Operations/Sec |
| Instance_status |
Indicates whether/not this instance is powered on. |

The table below lists the protocols that can be reported by this measure, and their numeric equivalents:
| Measure value |
Numeric value |
| Off |
0 |
| On |
1 |
Note:
By default, this measure reports one of the Measure values listed in the table above to indicate whether this instance is powered on or not. The graph of this measure however, represents the same using the numeric equivalents only. |
