Performance Statistics in N0C

Introduction

In this article, you will learn about a tool that allows you to track resource usage statistics for your hosting accounts.

Users will notice that we have maximized the information available to the customer. The fact that the data is displayed in real time makes the proposed solution particularly beneficial to our clients. Furthermore, if this kind of information allows you to notice that you are using a lot of resources, an increase in your plan for more performance is suggested.

Note : The PlanetHoster Glossary contains explanations on multiple topics and can be consulted to clarify certain terms.

Explanation of Resource Pools

When you log in to https://my.planethoster.com/ and click MY SERVICES -> Overview, you can see the Ressource Pool you paid for:

This resource pool determines the calculation of the number of hosting accounts.

The minimum number of resources per hosting account is:

ResourcesValue
CPU1 core
RAM1 GB
DISK I/O1 MB/s

The maximum number of resources per hosting account is:

ResourcesValue
CPU8 cores
RAM24 GB
DISK I/O24 MB/s



Definition of ressources

The following is a description of each of the resources for which statistics on their use are available:

RessourceDefinition
IOThe exchange of information between the processor and its associated peripherals is called input/output (IO).
CPUNumber of cores of the microprocessor solicited at a given time.
Mémoire virtuelleMechanism based on the use of a mass memory to help the physical memory.
Mémoire physique (RAM)The physical memory (also called random access memory, or RAM), is the memory in which a computer places data during processing. Its contents can be modified during normal use; it is usually erased as soon as the computer is turned off.

Available Statistics

Since your resource pool offered under the plan you paid for determines the calculation of the number of hosting accounts, it is important to know the usage of your resources. This way, you know if you are distributing your resources well from one account to another.

The statistics represented on the four graphs that we describe in detail in the paragraph Description of Statistics are extremely useful. Here is how to access and display the data in N0C:

  1. Click on Statistics -> Performance :
  1. Choose the period of time you are interested in for the display of the resources used.
  2. Hover your cursor over the points on the graph corresponding to the points in time for which data are to be displayed:

Description of Statistics

The following describes the data displayed on the statistical graphs. In all four cases, the x-axis (horizontal) corresponds to the point in time when the quantity displayed on the y-axis (vertical) is measured.

DataDescriptions
BandwidthThe maximum and average number of IO operations in bits per second (bps) at the time of execution of a combination of read and write tests at a given time. 
Memory usageThis data is displayed in MB:
-Limit memory usage (virtual and physical).
-Average virtual memory usage.
-Maximum virtual memory usage.
-Average physical memory usage.
CPU usagePercentage of maximum (Max UCT in CPU %) and average (Average UCT in CPU %) microprocessor cores requested at a given time. See Note below.
Memory errorsNumber of insufficient virtual memory errors and number of insufficient physical memory errors.
The statistics provide, at a given time, the number of insufficient virtual memory errors; they also provide, in MB and at a given time, the average and maximum usage.

Note : You can assign up to 8 cores (CPU) per hosting in N0C. It is up to you to decide how to distribute the 8 cores among your hosts. If 1 core has been assigned to a given hosting, the maximum you can request will be 100%. If more cores are assigned, the percentage will be in proportion. 
Thus, 400% and 800% mean that 4 cores and 8 cores respectively are requested at the maximum according to your assigned resources. For example, suppose you have assigned 2 cores on one of your hosts and the percentage indicates 227%: this means that you have exceeded the limit you have defined by 27%.
