The first tab Server Information groups the hardware characteristics of the servers in a table as follows:
|Name:||Name of server|
|Identifier:||Unique identifier of the server|
|THREAD#:||Number of threads|
|CPU Model:||Model of the CPU|
|CPU#:||Number of Cores in the server|
|CPU Freq:||Frequency of the CPU in MHz|
|Ram Cap:||Memory capacity of the server in MB|
|Power Min:||Consumption in Watt of server with a minimal processor consumption|
|Power Max:||Consumption in Watt of server with a maximum processor consumption|
Some properties are not always available for all servers. In this case the value of the property will appear as Null
The second tab Server Consumption shows information about the server consumptions. Consumptions are recorded and stored in a DC Scope database. In order to facilitate the organization of consumptions, metrics are calculated over a period of analysis which can contain a large number of logs. This information is presented in a table as follows:
|Period||Number of period|
|From||Start data collection date|
|To||End data collection date|
|Name||Name of Server|
|Nb of values||Number of logs of consumptions|
|CPU Consumption in %||Avg||Average CPU consumption in %|
|Min||Minimum CPU consumption in %|
|Max||Maximum CPU consumption in %|
|CPU \< 10||Percentage of logs of where the CPU consumption is less than 10%|
|CPU > 70||Percentage of logs of where the CPU consumption is more than 70%|
|RAM Consumption in %||Avg||Average RAM consumption in %|
|Min||Minimum RAM consumption in %|
|Max||Maximum RAM consumption in %|
|IO-Disk Consumption (MB/s)||Avg||Average disk consumption in MB/s|
|Min||Minimum disk consumption in MB/s|
|Max||Maximum disk consumption in MB/s|
|IO-Net Consumption (MB/s)||Avg||Average network consumption in MB/s|
|Min||Minimum network consumption in MB/s|
|Max||Maximum network consumption in MB/s|
By clicking on the server name, the period of analysis for that server will zoom in. Using this feature, the user can look for events in smaller periods of time. The minimum period of time for the analysis is one hour. Some consumptions are not always available for all servers, in this case the value of the consumption will appear as Null.
This frame displays general information about the physical server as the model, operative system, etc. It is possible to ad notes to the server and that will be only available in DC Scope. The blue button Get VM List provides the list of the VMs hosted in the server as well as general information of the VMs (VCPU, RAM, OS and VMware tools).
Allocation of resources
This section allows to analyze the resources assigned to VMs based on the resources of the physical server. The red line identifies the value that must not be exceeded when provisioning or allocating resources to VMs. The overflow threshold is calculated according to the allocation over commitment parameters set in the Capacity Planning Settings. For more information please refer to the Capacity Planning Settings of this document.
Distribution of allocations
It shows the allocation of VCPU and VRAM among the number of virtual machines in the server. In the example, 3 virtual machines have a RAM allocation between 2GB and 4GB, while only 1 virtual machine have a RAM allocation between 8GB and 16GB.
This frame represents the daily consumption of the physical server. This is average consumption for CPU, RAM, disk and network resources.
By passing the mouse over the chart, a more detailed information is provided regarding each resource.
Distribution of consumption
The first part of the frame compares the average consumption of CPU and RAM of the server under analysis with all the other servers. The second part of the frame presents the distribution of the maximum levels of CPU and RAM consumption observed by number of days.
In the example, from a total of 418 days of data, there were 233 days where the maximums levels of RAM consumption have been between 30% and 50% of the capacity of the server and 185 days where the maximums levels have been between 50% and 70%.
Evolution of resources
This frame shows the number of VMs that can be created in the server. The green circle represents the maximum number of VMs that can be created based on the average VM consumption. The blue circle represents the maximum number of VMs that can be created based on VMware best practices and the grey circle represents the maximum number of VMs that can be created according to the allocation over commitment parameters set in the Capacity Planning Settings.
According to the average consumption, DC Scope will calculate the saturation dates of CPU and RAM.
