CPU all utilisation
Percentage of CPU utilization that occurred while executing at the system level (kernel), the user level (application) and the percentage of time that the CPU or CPUs were idle during which the system had an outstanding disk I/O request.
Run queue length
Number of tasks waiting for run time.
System cache statistics
Total number of kilobytes the system paged in/out from/to disk per second, and number of major faults the system has made per second, those which have required loading a memory page from disk.
System load average for the last minute, the past 5 and 15 minutes. The load average is calculated as the average number of runnable or running tasks (R state), and the number of tasks in uninterruptible sleep (D state) over the specified interval.
Number of process
Number of tasks in the task list.
System memory utilization
Amount of memory used to cache data or as buffers by the kernel and free memory available in kilobytes.
Swap In/Out (pages/seconds)
Total number of swap pages the system brought in/out per second. The page size is usualy of 4096 bytes
Block In/Out (blocks/seconds)
Total amount of data read/write from the devices in blocks per second. Blocks are equivalent to sectors and therefore have a size of 512 bytes
