| | This is the start screen with some useful information on it about the machine |

| |  | This is just the CPU utilisation on a X Windows session that supports colour on AIX |

 | | This is the CPU Utilisation of an Idle machine which is POWER5 and is a Share Processor Logical Partitions (SPLPAR). |
| | This is what marketing calls a Micro Parition. |

| | Here it the same partition but with a workload that takes it near to the entitelment. |
| | Note the utilication is near 100% on the entitlement but this LPAR can go twice as fast as this if there is spared CPU cycles in the Shared Processor Pool |

| | And below is the LPAR stats at the same time: |

| | |
| | Here it the same partition but with a workload that has been taken the CPU use is well over the entitlement. |

| | If you workload is peaky it is worth getting an overview of these peaks and so get a feal for the average and peaks. |
| | This is provided by the Loger Term CPU View: |

| | Thee are lots of other stats that are useful |
| | |
| | Memory |
| | !nmon11_mem.gif! |
| | |
| | Kernel details |
| | | File-System details |
| | !nmon11_jfs.gif! |
| | |
| | Network initially shows the network troughputs and errors |
| | !nmon11_net.gif! |
| | If there are not errors the error details will disapear until there are errors |
| | !nmon11_net2.gif! |
| | |
| | If you use NFS this is the only tool to show you the statistics as they happen - here I am running ls -lR /NFS-mountpoint |

| | |
| | One key area for tuning is disks there are different ways to view these |
| | Simple disk graphs |
| | !nmon11_disk_graph.gif! |
| | The same data but in numbers and some more details like transfers (xter) |
| | !nmon11_disk_stats.gif! |
| | Then you might want to know about the types of disk and their connections |
| | !nmon11_disk_detail.gif! |
| | |
| | Disks are connected by adapters |
| | WARNING: the stats here are simply collected by adding up the disk stats - other devices like tapes are NOT included (there are no tape stats) |
| | !nmon11_adapt.gif! |
| | |
| | Top Processes are clearly important and there are lots of views for these |
| | |
| | Top 3 is the default |
| | !nmon11_top3.gif! |
| | Top 1 show some more details of the process |
| | !nmon11_top1.gif! |
| | Top 2 shows the releationships and collective stats |
| | | Top 2 shows the relationships and collective stats |
| | !nmon11_top2.gif! |
| | Top u shows the command name instead of the process name |
| | !nmon11_topuu.gif! |
| | Top U (upper case) shows the WLM classes too |
| | !nmon11_topU.gif! |
| | |
| | |
| | Releated to this is the Async I/O AIX kernel processes - note these are collected with the Top Processes so Top gets switch on at the same time. |

| | |
| | Workload Manager (WLM) Classes are also monitored |
