With these tools you can track different characteristics of your server, such as RAM (Random Access Memory), CPU Load Average and Disk Usage. Information about a php version and an operating system is also displayed.
RAM (Random Access Memory) is the hardware in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device's processor. RAM is the main memory in a computer. It is much more responsive than other kinds of storage, such as a hard disk drive (HDD), solid-state drive (SSD) or optical drive.
Average load - the average value of the system load over a certain period of time. This is the average of the computational work that the system performs. Expressed as a percentage of the maximum available CPU resources.
Disk usage (DU) refers to the part or percentage of computer storage that is currently in use. It contrasts with disk space or disk capacity is the total amount of space that a given disk is capable of storing. Disk usage is often measured in kilobytes (KB), megabytes (MB), gigabytes (GB) and/or terabytes (TB).
More suitable for dedicated servers. Warning: the data on the full (and free) disk capacity may not be correct, since the limits specified in the hosting tariff are not taken into account.
For this module to work server should give access to reading the files:
or be able to run "exec" or "shell_exec" from php.
If the data is not yet displayed in the module, then this can happen in two cases. The module may still be processing your site (usually no more than an hour). Or your server configurations do not meet requirements.
