5.4. Viewing Resource Consumption¶
Knowing how virtual environments consume host resources may help you prevent physical servers from overusing resources and reducing the performance of virtual environments.
The Resource Consumers table keeps track of the resource usage on the physical servers. Access the Resources page by going to Infrastructure > Resources tab.
In the List Settings section, you can specify the time interval for which you want to view the resource consumption statistics. To specify the time interval, choose one of the following items from the corresponding drop-down menu:
- Last Hour
- Last Day
- Last Week
In the Resource Consumers section, you can see information such as disk usage, memory usage, incoming and outcoming traffic of all the virtual environments. This information is presented in the Virtual Environments table and displayed according to the settings made on the Select Columns drop-down menu. If all the columns are selected, this table presents the following:
|Virtual Environment||The virtual environment name.|
|Hardware Node||The physical server that hosts the virtual environment.|
|CPU Usage||The host CPU time consumed by the given virtual environment for the selected time frame.|
|Disk Host Usage||The host disk space consumed by the given virtual environment, in percents.|
|Disk Quota Usage||The percentage of the disk space usage compared to the total amount of disk space allocated to the virtual environment.|
|Disk Usage||The usage of the disk space by the virtual environment.|
|Memory Host Usage||The host memory consumed by the virtual environment, in percents.|
|Memory Quota Usage||The percentage of the memory usage compared to the total amount of memory allocated to the virtual environment.|
|Memory Usage||The usage of the memory by the virtual environment.|
|Incoming Traffic||The amount of the virtual environment incoming traffic, in bytes.|
|Outgoing Traffic||The amount of the virtual environment outgoing traffic, in bytes.|
If you click a column name, you will see an upward triangle displayed to the right of the column name and virtual environments consuming the corresponding resource in ascending order. If you click the column name once again, you will see a downward triangle displayed to the right of the column name and virtual environments consuming this resource in descending order.
