MBS( "SystemInfo.LinuxSystemInfo" )
Parameters
none
Result
Returns JSON or error.
Description
Queries Linux system information details.Returns JSON with various information about the linux environment.
Values include:
| UpTime | Seconds since boot |
| Loads | 1, 5, and 15 minute load averages |
| TotalRAM | Total usable main memory size |
| FreeRAM | Available memory size |
| SharedRAM | Amount of shared memory |
| BufferRAM | Memory used by buffers |
| TotalSwap | Total swap space size |
| FreeSwap | Swap space still available |
| Processes | Number of current processes |
| TotalHigh | Total high memory size |
| FreeHigh | Available high memory size |
| MemoryUnit | Memory unit size in bytes |
| ConfiguredProcessors | How many CPU cores. |
| AvailableProcessors | How many available to you. |
| TotalPhysicalPages | Total physical memory pages |
| AvailablePhysicalPages | Available memory pages. |
Usually RAM numbers are in bytes and since page size is usually 4096 bytes, TotalPhysicalPages * 4096 is TotalRAM.
For loads, you may need to divide by core count if you like to present it as percentage of CPU usage.
If loads are > AvailableProcessors, you may have not enough CPU power.
If FreeSwap is below TotalSwap, you have not enough RAM.
