Description |
Measurement Unit |
Interpretation |
| Status |
Indicates whether/not this VM is running. |
Number |
The values reported by this measure and its numeric equivalents are mentioned in the table below:
| Measure Value |
Numeric Value |
| Running |
1 |
| Stopped |
0 |
Note:
By default, this measure reports the above-mentioned Measure Values while indicating the state of the VM. In the graph of this measure however, the state is indicated using the numeric equivalents only. |
| Tot_mem |
Indicates the total amount of memory allocated for this VM. |
MB |
|
| Use_mem |
Indicates the amount of memory used by this VM. |
MB |
Ideally, the value of this measure should be much lesser than the value of the Total memory measure. If the value of this measure is equal to or is rapidly approaching the value of the Total memory measure, it means that the VM is running out of memory resources. |
| Free_mem |
Indicates the amount of memory available for use in this VM. |
MB |
Ideally, the value of this measure should be high. |
| Mem_utilize |
Indicates the percentage of memory utilized by this VM. |
Percent |
A value close to 100% is indicative of excessive memory usage by a VM, and signals a potential memory contention on the VM. |
| Max_cpu |
Indicates the minimum number of CPU resources guaranteed to this VM. |
Number |
|
| Cpu_usage |
Indicates the percentage of CPU used by this VM. |
Percent |
A value close to 100% is indicative of excessive CPU usage by a VM, and signals a potential CPU resource contention on the VM. |
| Up_time |
Indicates the total time that this VM has been up since its last reboot. |
|
This measure displays the number of years, months, days, hours, minutes and seconds since the last reboot. Administrators may wish to be alerted if a VM has been running without a reboot for a very long period. Setting a threshold for this metric allows administrators to determine such conditions. |
| Total_disk |
Indicates the total amount of disk space allocated for this VM. |
GB |
|
| Used_disk |
Indicates the amount of disk space used by this VM. |
GB |
Ideally, the value of this measure should be much lesser than the value of the Total disk space measure. If the value of this measure is equal to or is rapidly approaching the value of the Total disk space measure, it means that the VM is running out of disk space. |
| Free_disk |
Indicates the amount of disk space available for use in this VM. |
GB |
A high value is desired for this measure. |
| Disk_utilize |
Indicates the percentage of disk space utilized by this VM. |
Percent |
A value close to 100% is indicative of excessive disk usage by a VM, and signals a potential CPU resource contention on the VM. |
| Disk_read |
Indicates the amount of data read from the disk of this VM per second during the last measurement period. |
MB/sec |
|
| Disk_write |
Indicates the amount of data written to the disk of this VM per second during the last measurement period. |
MB/sec |
|
| Net_in |
Indicates the rate at which the data was received by this VM through all network interfaces. |
Mbps |
|
| Net_out |
Indicates the rate at which the data was sent out through all the network interfaces by this VM. |
Mbps |
|
| Disk_throput |
Indicates the rate at which the data is read from and written to the disk of this VM. |
MB/sec |
Ideally, the value of this measure should be high. A steady decrease in the value of this measure could indicate that the disk is experiencing a congestion that requires immediate attention from administrators. |
| Tot_network |
Indicates the total number of I/O Operations per second on this VM. |
Mbps |
