IBM AIX Monitoring

Extend the Life of your IBM AIX Systems

Sightline Enterprise Data Management (EDM) is a powerful IT infrastructure monitoring and real-time analytics solution that provides maximum control over any IT environment. The Sightline™ Power Agent™ for IBM® AIX® Systems collects and reports performance data from all of the key components of the operating system, including process information. EDM enables IT teams to continuously monitor the entire system in real time in order to proactively predict performance issues and prevent unplanned downtime and data loss. Its highly interactive, visual tools are used to achieve results in minutes, accelerating discovery and investigation within any IT infrastructure.

AIX Performance Metrics

Sightline EDM collects these specific IT performance metrics on IBM AIX systems:

CPU Statistics

Sightline provides global as well as per CPU statistics. Sightline reports types and rates of context switching globally as well as per process; which incurs system CPU cycles and diminishes the amount of CPU left for user processing.

Memory Statistics

These metrics include Space Utilization, Paging, and Swapping Statistics. Buffer Cache – The Buffer Cache is a block of memory where I/O’s are cached. This greatly enhances the performance of the disk I/O subsystem, but at the expense of available memory.

Disk Statistics

Sightline reports disk statistics provided by the kernel. Depending on the UNIX platform, they can include %Busy, Volume of Traffic, Wait Times, and Service Times, %Read, %Write, etc.

Network Statistics

Network statistics are collected at the controller level. Sightline collects Net Traffic Rates, Collisions (sign of network problems) and Resends (sign of controller problems), Number of Packets, Volume of Traffic, and TCP Stats, Input Packets/Sec, Output Packets/Sec, Collisions/Sec, IP Pkts Received/Sec.

File System

File systems can be mounted across physical disks. Their space on most UNIX systems is set and cannot be changed easily, so it is important to monitor their use.

Hypervisor

The hypervisor is the piece of firmware that provides the virtualization support for running LPARs and deals with assigning resources to LPARs.

TTY

TTY metrics record utilization of terminal lines. Sightline reports these rates in several forms.

Kernel Variables

This group contains user changeable metrics that affect how much memory the kernel will utilize with buffers and tables.

 


 

Process Level Data

Event data is used to monitor process-level utilization; for example:

    • Pid# – The Process Identification Number
    • Userid – The name of the User that owns this process
    • Taskname – The name of the process
    • Arguments – The arguments used when initiating the process
    • Usr% (User CPU utilization) – The amount of User CPU this process used during the sample interval. On a multi-processor machine this is the value of CPU usage for this process on all CPU’s
    • Sys% (System CPU utilization) – The amount of System CPU this process used during the sample interval. On a multi-processor machine this is the value of CPU usage for this process on all CPU’s
    • Cuser% (Child user CPU utilization) and Csys% (Child system CPU utilization) – The amount of User CPU and System CPU that children of this process used. You will only see values when a child of this process completes during the interval
    • Size K (Process size) – The amount of memory that this process is using in Kilobytes
    • Pri (Priority Level) – Level of Priority of the process
    • BRead and BWrite – The number of Block Reads and Writes done by this process during the interval
    • PgFlt – The number of Page Faults for this process during the interval
