Measures reported by KVMDmnJobInfoTest
Live migration refers to the process of moving a running virtual machine or application between different physical machines without disconnecting the client or application. Memory, storage, and network connectivity of the virtual machine are transferred from the original host machine to the destination. For a VM migration to be smooth and hassle-free, it is essential to monitor the memory, storage and time that is required for migration. The KVMDmnjobInfoTest exactly does the same!
This test captures the total amount of memory, storage and files of the VM that are to be transferred during migration and provides exact pointers to how much of these have already been transferred and how much of these are currently pending for a migration to be complete. Additionally, you could figure out the time since the migration process in the VM started and the estimated time of completion.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Data_tot |
Indicates the total amount of data that is to be transferred during live migration of this VM. |
MB |
|
| Data_proc |
Indicates the total amount of data that is processed since the beginning of this VM migration. |
MB |
A high value is desired for this measure. |
| Data_rem |
Indicates the amount of data that is yet to be transferred for this VM to be completely migrated. |
MB |
A high value for this measure indicates that VM migration may take too long to complete. |
| File_tot |
Indicates the total number of files that are to be transferred during live migration of this VM. |
Number |
|
| File_proc |
Indicates the total number of files that are processed since the beginning of this VM migration. |
Number |
|
| File_rem |
Indicates the total number of files that are yet to be transferred for this VM to be completely migrated. |
Number |
An abnormally high value for this measure is a cause of concern. |
| Mem_tot |
Indicates the total amount of memory that is currently required for migrating this VM. |
MB |
|
| Mem_proc |
Indicates the amount of memory that is already consumed for migrating this VM. |
MB |
|
| Mem_rem |
Indicates the amount of memory that is required to migrate this VM completely. |
MB |
|
| Time_elapse |
Indicates the time elapsed since the beginning of this VM migration. |
Secs |
|
| Time_rem |
Indicates the time that is still required for completing this VM migration. |
Secs |
An abnormally high value for this measure indicates trouble during migration of the VMs. This could be due to problems such as processing bottleneck, inadequate memory resources allocated for migration, network congestion etc. |
