Information
The first tab Server Information tab groups the hardware characteristics of the servers into a table, which contains the following information:
| Item | Description |
|---|---|
| Name: | Name of the server |
| Identifier: | Unique server identifier |
| OS: OPERATING SYSTEM | Operating system |
| Model: | Server model |
| THREAD#: | Number of logical cores |
| CORE#: | Number of physical cores |
| CPU Model: | Processor Model |
| CPU#: | Number of server cores |
| CPU Freq: | Frequency of a processor in MHz |
| Ram Cap: | Memory capacity of the server in MB |
| Power Min: | Power consumption, in Watt, of the server with minimum processor consumption |
| Power Max: | Power consumption, in Watt, of the server with maximum processor consumption |
Some properties are not always available for all servers, so the value of the servers, the value of the property is then equal to Null
Consumption
The second tab, Server Consumptiondisplays information about server consumption in a table. Consumption is measured frequently and stored in a database. In order to facilitate the exploitation of these measurements, several counters are calculated over an analysis period that can contain a large number of values. These different counters are displayed in a table, the name of the column describes the counter displayed:
| Item | Description | |
|---|---|---|
| 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 |
Some consumptions are not always available for all servers, the servers, the consumption value is then equal to NULL.
By clicking on the server name, a zoom is performed in order to divide the analysis the analysis period into several smaller periods. With the help of this feature, the user can precisely analyse the consumption of a server. The minimum analysis period is one hour
Synthesis
General Information
This screen displays general information about the physical servers, such as model, operating system, etc. It is possible to add notes to a server, which are then made available in DC Scope.
Allocation of resources
This section is used to analyse the resources allocated to virtual machines virtual machines according to the resources of the physical server being analysed. The red zone identifies the value to be allocated / provisioned to the virtual virtual machines that should not be exceeded. The overflow threshold is calculated from the from the parameters of the capacity planning.
Distribution of allocations
This displays the distribution of the number of virtual machines according to their according to their allocation in vcpu or ram. In the example below, three virtual machines have memory allocations between 16 GB and̀ 32 GB.
Distribution of consumption
When the average option is selected, the average
consumption of the analysed server compared to all servers.
servers. This allows the analysed server to be positioned in relation to
to the others.
When the maximum option is selected, the
distribution of the maximums observed day by day is displayed. In our example, there are
example, there are 221 days where the maximums are between 11 and 30% of the server's
capacity and 242 days where the maximums are between 71 and 90% of the server's RAM capacity. This shows that
to see that not all days have peaks above
90 %.
Evolution of resources
This section allows you to follow the evolution of the number of virtual machines virtual machines that are running on the server being analysed.
- The green circle indicates the number of virtual machines that can still be created based on the average consumption.
- The blue circle indicates the number of virtual machines that can still be created based on the following conditions: - 4 vcpu per logical core - 100% of the physical server ram.
- The grey circle shows the number of virtual machines that can still be created under the following conditions: - 4 vcpu per logical core - 166% of the physical server's ram. the average power consumption, information on CPU and RAM saturation is RAM saturation is given.
Troubleshooting
This framework allows to identify the resource degradation of the server being analysed. For the semantics of the colours and the slope of the the arrow see the section troubleshooting.
Each circle allows you to quickly identify the CPU, Network and RAM behaviour of the selected server. By clicking on each one, you get detailed detailed information about the resource(s) that are exceeding exceed the best practice thresholds.
