The system conditions of the VM hosts selected in the system conditions window CI list is displayed as a graph at [System Conditions] in the lower part of the window. Up to five VM hosts can be displayed at once in the graphs. If more than five VM hosts are selected, the first five are displayed.
The system conditions contents can be switched by clicking the [System Conditions] tabs.
The table below shows the contents under the [System Conditions] tabs.
Tab name | Display content (*1) | Graph type | Display interval | Display interval switching (*2) |
|---|---|---|---|---|
Total | Totals for each status | Vertical bar graph | 30 minutes, starting from the current time | Not possible |
CPU | CPU utilization | Horizontal polyline graph | One hour/day/month/year from the current time | Possible |
Disk | Disk R/W usage | Horizontal polyline graph | One hour/day/month/year from the current time | Possible |
Disk R/W count | Horizontal polyline graph | One hour/day/month/year from the current time | Possible | |
Memory | Memory usage | Horizontal polyline graph | One hour/day/month/year from the current time | Possible |
Network | Network usage (*3) | Horizontal polyline graph | One hour/day/month/year from the current time | Possible |
All | Overview of all the above statuses | Horizontal polyline graph | One hour/day/month/year from the current time | Possible |
*1: Information is displayed using a different color for each L-Server.
*2: The display interval can be switched to a shorter interval by clicking the data plotting area of a horizontal polyline graph, or switched to a longer interval by clicking outside the data plotting area.
*3: Will not display if the VM host server virtualization software used is either RHEL5-Xen, RHEL-KVM, OVM for x86 3.x or OVM for SPARC.
Note
The system conditions data is not reflected in the display until collection at the fixed intervals shown below is completed.
Check the display after the fixed intervals shown below.
Tab name | Display period (*) | Collection time required before displaying |
|---|---|---|
Total | 30 days | one whole day (from 0:00 to 23:59) |
CPU | one hour | ten whole minutes (from 0 minutes to 9 minutes) |
one day | one whole hour (from 0 minutes to 59 minutes) | |
one month/one year | one whole day (from 0:00 to 23:59) |
* Note: The display period in each tab except for Total tab can be selected from one hour, one day, one month, or one year.
System conditions data is not displayed if the power is off at the monitored L-Server.
Proper data collection cannot take place if the VM host to be monitored continuously indicates CPU utilization of 100%. Accordingly, a display resembling one of the examples below may appear.
Example:
CPU utilization rate displays as exceeding 100%.
Data cannot be collected, graph does not display.
If the server virtualization software of the VM host is Hyper-V, network usage of a virtual network is the sum of network usage of the physical NICs that are registered with the virtual network. Because of this, in a system environment where each physical NIC of a teaming configuration is registered with virtual networks, each NIC is included for the calculation, therefore network usage is doubly added up.
To provide a viewpoint of hosts, memory usage is displayed as the total memory usage of a host including usage in the VM kernel and the service console. The memory usage of the system conditions display can be used to check the total memory usage of a host at that moment.
Display examples for the [Total] tab and the [All] tab are shown below.

[All] tab
At each tab, the following icons displayed in the title bar can be used:
Icon | Tool tip | Explanation |
|---|---|---|
| Update | Updates the displayed contents |
| Download CSV file | Downloads the graph data in CSV format |
| Minimize | Minimizes the specified window |
| Maximize | Maximizes the specified window |
| Restore | Restores the maximized window |
The table below shows the CSV file items if data is downloaded from each graph.
Note that the CSV file encoding is Shift-JIS.
