# AIX Plugin
## Processor Extension
The processor extension works for both AIX and Linux on the Power ppc64/ppc64le architecture.
Metrics reported are:
- **mode** - Processor mode, Capped or Uncapped
- **type** - Processor type, Shared or Dedicated
- **lcpu** - Number of logical CPU's available for this partition
- **ent** - Processor entitlements available for this partition
- **user** - Indicates the percentage of the entitled processing capacity used while executing at the user level (application).
- **sys** - Indicates the percentage of the entitled processing capacity used while executing at the system level (kernel).
- **idle** - Indicates the percentage of the entitled processing capacity unused while the partition was idle and did not have any outstanding disk I/O request.
- **wait** - Indicates the percentage of the entitled processing capacity unused while the partition was idle and had outstanding disk I/O request(s).
- **physc** - Indicates the number of physical processors consumed.
- **entc** - Indicates the percentage of the entitled capacity consumed.
- **lbusy** - Indicates the percentage of logical processor(s) utilization that occurred while executing at the user and system level.
## Memory Extension
Metrics reported are:
- **total** - Total amount of memory (in KB).
- **used** - real memory consumption (in KB).
- **free** - free memory for use (in KB).
- **pin** - pinned memory consumption (in KB).
- **virtual** - virtual memory consumption (in KB).
- **available** - available memory (if freeing up virtual) (in KB).
- **paged** - paging space consumption (in KB).
*Pinning a memory region prohibits the pager from stealing pages from the pages backing the pinned memory region.*
## Disk Extension
Only reports first device found. Improvements on the TODO.
Metrics reported are:
- **device** - Name of device.
- **reads** - The total number of KB read.
- **writes** - The total number of KB written.

# Linux Plugin
## Processor Extension
Reports the following metrics seen:
- **user** - Percentage of CPU time spend on user processes.
- **sys** - Percentage of CPU time spend on system processes.
- **wait** - Percentage of CPU time spend on waiting (for i/o).
- **idle** - Percentage of CPU time spend on idle (doing nothing).
- **busy** - Percentage of CPU time not spend on idle (working).
## Memory Extension
Reports the following metrics, from the *free* command:
- **total** - The total amount of (installed) memory (in KB).
- **used** - Used memory (calculated as total - free - buffers - cache) (in KB).
- **free** - Unused memory (MemFree and SwapFree in /proc/meminfo) (in KB).
- **shared** - Memory used (mostly) by tmpfs (Shmem in /proc/meminfo) (in KB).
- **buffers** - Sum of buffers and cache (in KB).
- **available** - Estimation of how much memory is available for starting new applications, without swapping (in KB).
- **usage** - Percentage of memory used out of the total amount of memory.
## Disk Extension
Only reports first device found. Improvements on the TODO.
Metrics reported are:
- **device** - Name of device.
- **reads** - The total number of KB read.
- **writes** - The total number of KB written.
