- Load Test HP-UX Server Monitoring

HP-UX monitoring

The HP-UX monitoring module allows NeoLoad to retrieve system information from HP-UX platforms during a load test, using either the Telnet or SSH protocol to connect to your servers.

The HP-UX module has been validated on HP-UX 11.

The counters

NeoLoad opens a session on the server and uses system commands to retrieve the performance counters.

The available counters are divided into 3 categories:

• System

  • CPU User. User time for normal and low priority processes. Breakdown of percentage usage of CPU time.

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

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

  • Interruptions Count. Device interrupts per second (nonclock).

  • Context Switch Count. CPU context switch rate (switches/sec).

  • Processes Runnable. The numbers of processes in run queue.

  • Processes Sleeping. The numbers of processes blocked for resources (I/O, paging, etc.).

  • Processes Swapped. The numbers of processes runnable or short sleeper (< 20 secs) but swapped.

• Memory

  • Active virtual pages.

  • Free List Size. Size of the free list.

  • Pages Reclaims Per Second. Report information about page faults: page reclaims per second. (average each five second).

  • Address translation faults. Report information about page faults: Address translation faults per second. (average each five second).

  • Processes swapped in. Processes swapped in per second. (average each five second).

  • Processes swapped out. Processes swapped out per second. (average each five second).

  • Pages paged in. Pages paged in per second. (average each five second).

  • Pages pages out. Pages paged out per second. (average each five second).

  • Pages freed per second. Pages freed per second. (average each five second).

  • Anticipated short term memory shortfall. Anticipated short term memory shortfall. (average each five second).

  • Pages scanned by clock algorithm. Pages scanned by clock algorithm per second. (average each five second).

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

  • Kilobytes transferred per second. The number of kilobytes transferred per second.

  • Seeks per second. The number of seeks per second.

  • Millisecond per average seek. The number of milliseconds per average seek.
