【软件性能测试-LoadRunner实战技能 15】== LoadRunner_监控:Unix performance monitoring with LoadRunner

When monitoring the performance of a UNIX system using LoadRunner you need to enable

rstatd on the server being tested.



Once you've enable rstatd,(

rstatd

RPC.RSTATD(8)
             BSD System Manager’s Manual            RPC.RSTATD(8)

NAME

rstatd
, rpc.rstatd
 - kernel statistics server

SYNOPSIS

rpc.rstatd

DESCRIPTION

rpc.rstatd
 is a server which returns performance statistics obtained from

     the kernel.  These statistics are usually read using the rup(1)
 command.

     They are also used by the rpc.lockd(8)
 server during crash recovery.  The

     rpc.rstatd
 daemon is normally invoked by inetd(8)
.

     rpc.rstatd
 uses an RPC protocol defined in /usr/include/rpcsvc/rstat.x
.

iN LoadRunner Controller you se a number of counters which LoadRunner

can monitor.









I've tried to define the UNIX counters and where applicable I've described the Windows and UNIX counters.

UNIX counter	Windows Counter	Description
Average Load*	N/A	The sum of the number of processes waiting in the run queue plus the number currently executing.
Collision rate	N/A	The total number of network collisions/sec
Context switch rate	System - Context Switches/sec	The rate at which processors switch from executing one thread toanother. High switch rates can indicate performance problems as serversjuggle multiple running applications.
CPU utilisation	%Processor Time	The percentage of elapsed time that the process spends executing non-idle threads.
Disk traffic	%Disk time	The percentage of elapsed time that the disk(s) are busy servicing read or write requests.
Incoming packets error rate	Packets received errors	The number of packets received containing errors that precvent them from being delivered to a higher OSI layer protocol.
Incoming packets rate	Packets received/sec	The number of packets received on the network interface
Interrupt rate	Interrupts/sec	Average rate at which the processor receives and services hardwareinterrupts. Processes generate an interrupt when they finish a task andneed to report that fact to the CPU.
Outgoing packets error rate	Packets outbound errors	The number of packets that can't be transmitted due to errors
Outgoing packets rate	Packets sent / sec	The rate at which packets are sent on the network interface
Page-in rate	Pages Input/sec	The rate at which pages are read from disk to resolve hard pagefaults. Hard page faults occur when a process refers to a page invirtual memory which is not in it's working set or available elsewherein physical memory and has to be read from disk.
Page-out rate	Pages Output/sec	The rate at which memory pages are written to disk to free up space in physical memory.
Paging rate	Paging rate	The rate at which pages are read from disk or written to disk. This is the sum of Pages Input/sec and Pages Output/sec.
Swap-in rate	N/A	The number of pages read into memory per second
Swap-out rate	N/A	The number of pages written out of memory per second
System mode CPU utilization	Processor - %Priviledged time	The percentage of elapsed time that the processor spends executing user threads (i.e. running applications)
User mode CPU utilization	Processor - %User time	The percentage or elapsed time that the processor spends executing priviledged or system mode threads.
