Exceeding Hosting Limits (LVE)

If you experience slowdowns or errors (Error 500, 503, 508) when using your current SWIZZ hosting plan, or if all website components are not displayed correctly, the LVE limits of your hosting plan may have been reached or exceeded.

The LVE (Lightweight Virtual Environment) technology enables you to monitor the use of website resources, among other things.

The limits for each plan are shown in the table on the https://www.swizzonic.ch/hosting/linux/ page of our website.


How can you control the resources?

  1. Log in to your control panel at https://www.swizzonic.ch. If you don't remember how to do this, please refer to this manual.
  1. Select one of the hosts you have available, in the side section of your panel
  1. On the dashboard click on Manage

  1. In the Metrics section, click on Resource Usage
  1. Click on Current Usage
  1. On the Resource Usage page you can view the resource consumption graphs
  • The time interval selector; selection of predefined or manually modifiable time frames, which can be displayed in minutes, hours or days.
  • The graph of faults (failures or errors): This visualizes the average value of exceedances for the defined time interval. A good indicator that everything is going well is when no entries are visible.
  • The overview table for resource utilization: Column f (faults) shows overruns in the reference hour. The indicator for smooth functionality is the number 0. Column a shows the average value. Column l in turn shows the maximum value.

The values represented in the graphs are average values.


Details of the various types of faults

CPU Usage

This value shows the proportion of CPU usage of all running processes. As soon as the value reaches 100%, the full available performance is utilized.

Impact: The performance of the website is slowed down

I/O usage

This key figure shows how many bytes per second programs can read or write.

Impact: The performance of the website is slowed down

IOPS

This value illustrates how many operations per second are generated by the programs.

Impact: The performance of the website slows down, especially when demanding processing operations are required that involve a large number of read and write accesses to the hard disk.

Entry processes

Refers to the total number of script, application and cron processes in the hosting package.

Impact: Once the limit has been reached, HTTP requests are no longer processed by the website. Instead, a 508 error page is displayed until the number of Entry Processes requests falls below the limit again.

Number of processes

This value shows the proportion of CPU usage of all running processes. As soon as the value reaches 100%, the full available performance is utilized.

Impact: If the limit is exceeded, cron jobs and other scripts, as well as HTTP requests for non-PHP content, are no longer processed. This leads to the affected websites displaying 503 or 500 errors.

Physical memory usage

Describes the amount of memory used by running processes.

Impact: Error 503 or 500 is displayed on the website.
