- Web Testing Software AIX Monitoring

AIX monitoring

The AIX monitoring module allows NeoLoad to get system information from IBM AIX plateforms during the test, using either the Telnet or the SSH protocol to connect to your servers.

The AIX module has been validated on AIX 5.

The counters

NeoLoad will open a session on the server, and use system commands to get the performance counters.

The available counters are divided into 3 categories:

• System

  • CPU User. User time. Breakdown of percentage usage of CPU time.

  • CPU System. System time. Breakdown of percentage usage of CPU time.

  • CPU Idle. CPU idle time. Breakdown of percentage usage of CPU time.

  • Interruptions Count. Device interrupts. Trap and interrupt rate averages per second over the sampling interval.

  • Context Switch Count. Kernel thread context switches. Trap and interrupt rate averages per second over the sampling interval.

  • Processes Runnable. Average number of runnable kernel threads over the sampling interval. Runnable refers to threads that are ready but waiting to run and to those threads already running.

  • Processes Sleeping. Average number of kernel threads placed in the VMM wait queue (awaiting resource, awaiting input/output) over the sampling interval.

• Memory

  • Active virtual pages.

  • Free List Size. Size of the free list..

  • Pager in/out list. Pager input/output list. Average pages per second over the interval..

  • Paged In Per Second. Pages paged in from paging space. Average pages per second over the interval.

  • Paged Out Per Second. Pages paged out to paging space. Average pages per second over the interval.

  • Freed Per Second. Pages freed (page replacement). Average pages per second over the interval.

  • Pages Scanned by page-replacement. Pages scanned by page-replacement algorithm. Average pages per second over the interval.

  • Clock cycles page-replacement. Clock cycles by page-replacement algorithm. Average clock cycles per second over the interval.

• Disk. The disk section monitors are available per device.

  • Data transferred (read/write). Indicates the amount of data transferred (read or written) per second to the drive. Different suffixes are used to represent the unit of transfer. Default is in bytes per second.

  • Transfers per second. Indicates the number of transfers per second that were issued to the physical disk. A transfer is an I/O request to the physical disk. Multiple logical requests can be combined into a single I/O request to the disk. A transfer is of indeterminate size.

  • Read transfers per second. Indicates the number of read transfers per second.

  • Write transfers per second. Indicates the number of write transfers per second.

  • Data read per second. Indicates the amount of data read per second, from the drive. Different suffixes are used to represent the unit of transfer. Default is in bytes per second.

  • Data written per second. Indicates the amount of data written per second, to the drive. Different suffixes are used to represent the unit of transfer. Default is in bytes per second.

  • Disk activity (percent). Indicates the percentage of time the physical disk was active (bandwidth utilization for the drive).
