AIX load
=======================================================
Retrive AIX performance information from remote servers.
Usage:
------
``` shell
aix_load "hostname"
```
Example for single server:
``` shell
aix_load sdp7a
```
Example for multiple servers:
``` shell
aix_load sdp
```
Legend:
-------
* **HOST** - Server hostname
* **EXEC TIME** - Server local time, when performance information was requested
* **HW TYPE** - Server hardware type
* **THREADS** - Number of virtual processors (CPU threads). Used for max IOWAIT and RUNQ cacluation
* **RUNQ** - Shows the number of tasks executing and waiting for CPU resources. When this number exceeds the number of THREADS on the server - a CPU bottleneck exists
* **BLKQ** - Shows the number of tasks blocked to execution. If this value is higher then 2 and RUNQ is high - you probably have problems
* **CPU IDLE** - Server CPU idle cycles (Higher is better)
* **CPU USER** - Server CPU users cycles (Lower is better)
* **CPU SYSTEM** - Server CPU system cycles (Lower is better)
* **COMP RAM** - Percentage of Server computational RAM (MAX alloved - 90)
* **IOWAIT** - Percentage of time the CPU is idle AND there is, at least, one I/O in progress. Depends from performance of server's storage. Iowait more 25 - system is probably IO bound
* **IS DISK LOAD** - Indicates current Server disks load status (Should be NO)
* **LOADED DISKS** - Server most loaded discs. Shows diskname and tm_act percentage. Percent of time the device was active (we can see if disk load is balanced correctly or not, 1 used heavily others - not. 100 means disks always was busy when requested statistics. On some SDPs it can reach 260, bue to mirriring configuration.)
