The types of load testings
supported by loadrunner are:
Load Testing: By using the loadrunner the load test can be simulated for multiple
simultaneous users, similar to realistic number of
users.
Endurance / Longevity /
Soak Testing: By
using the loadrunner the load
test can be simulated for longer
durations
Stress
Testing: By using the loadrunner the load test can be simulated with multiple users
till the stress point reaches with incremental increase in the number of users.
Spike Testing: By using the loadrunner, during
the load test execution spikes can introduced by way
of adding thenumber of users.
Capacity Testing: Using loadrunner systems
capacity can be tested for the future incremental in business. For example, if
the current AUT system configuration supports 1000 users. Due to the expansion
in business, if the numberof
users are increased to 10000. Does the existing environment supports or any new
systems to be procured. The decision can be taken by way of conducting the load tests using load runner.
Scalability
Testing: Scalability can be compared
using some of the auto generated graphs, like average response times under
load.
The scenario
types available in loadrunner controller are:
1) Manual scenario
2) Manual scenario by percentage
3) Goal oriented scenario
1) Manual scenario
2) Manual scenario by percentage
3) Goal oriented scenario
Goal Oriented scenario is one type of load test scenario in controller.
Goal Oriented scenario is used
for creating the scenario based on the customer expected objectives.
For example: if the customer
wants to achieve the 100 hits per second with variable number of users like
minimum number of users 50 and maximum number of users 150. Then you may need
to select the type of load test as goal oriented.
Normally the goal oriented
scenario should be executed for long durations to achieve the customer goals or
objectives.
Manual scenario is one of the
types of load runner scenarios. This will be used for simulating the real time load tests.
The manual scenario can be built
by creating groups and specifying the script, the load generator, and the
number of Vusers included in each group
5.
What
is the difference between manual scenario and goal oriented scenario in
loadrunner controller?
|
Manual scenario
|
Goal oriented scenario
|
|
Used to simulate the real time loads based on the fixed time
and fixed number of virtual users
|
Used for simulating the load, based on the
objectives defined by the customer expected objectives like HTTP hits,
transactions per sec and transaction response time etc.
|
|
The duration is fixed. Since the time clearly defined in real
world scehdules
|
The duration is always much more than the duration mentioned
in goal oriented scenarios. Since the goal will be achieved after the mentioned
time
|
|
Acceleration and deceleration of the users will
happen based on theschedule design
|
Acceleration and deceleration of the users will
happen automatically, based on the goal defined
|
Goal oriented scenario:
The goal oriented scenario is selected, only when you want to simulated the customer objectives or goals like HTTP hits per second or transactions per second or transaction response time.
The goal oriented scenario is selected, only when you want to simulated the customer objectives or goals like HTTP hits per second or transactions per second or transaction response time.
Manual scenario:

choose different types of goals based on the customer given objectives for the load test.
There are 5 types of goals available. Select the type of goal you want for the scenario.
There are 5 types of goals available. Select the type of goal you want for the scenario.
Pages per Minute (for
Web Vusers only). Enter a
target number of downloaded pages
per minute that you would like your scenario to reach, and select a minimum and maximum number of Vusers
for the scenario.
Virtual Users. Enter a target number of
virtual users that you would like your scenario to reach.
Hits per Second (for Web
Vusers only). Enter a
target number of hits per second (HTTP requests per
second) that you would like your scenario to reach, and select a minimum and maximum number of Vusers
for the scenario.
Transactions per Second. Enter a target number of
transactions per second that you would like your scenario to reach, and select a minimum and maximum number of Vusers
for the scenario.
Transaction Response
Time. Enter a
target transaction response time that you would like your scenario to reach,
andselect a minimum and maximum
number of Vusers for the scenario.
Using the load behavior tab,
you can set when the ramp up to achieve the goal.
The ramp up can be set in three ways
Automatic. Instructs the Controller to
run the default number of Vusers in a batch. Controller starts with the minimum
number of Vusers. And runs for two minutes. If the goal is not achievable, the
scenario automatically increases the users to achieve the goal.
Reach target X after. Select the amount of scenario time you want
to elapse before the Controller reaches your target. This is the
minimum time you have given. The
controller takes much larger time
than mentioned here.
Step up by (not available for the Transactions per Second
and Transaction Response Time goal types). Select the gradation according to which you
want the Controller to reach your target (x number of
virtual users/hits/pages every x amount of time).
There is a check box Do
not change recorded think time in Edit scenario goal. If it is not
checked, the controller will minimize the think time, and runs the load
test. So, due to reduction in think time the frequency
of the hits will increase.
Note: If you select this option, you may need to increase the number of Vusers in your scenario in order to reach your target
Note: If you select this option, you may need to increase the number of Vusers in your scenario in order to reach your target
Goal oriented scenario
scenarios will execute based on the goals defined. The main objective of the
goal oriented scenario is to maintain the goal throughout the load test execution.
For example: You are running
goal oriented scenario with the goal of 100 hits per second, with minimum
number of users as 50 and maximum number of users as 150. If the actual hits
per second is coming around 75, when the load test is running with 50 users, then the
controller automatically increases the number of users based on the required
hits. When the number of hits are above the goal, then the number of users will
be decreased accordingly
13.
What are the options can be chosen if the load target is not reachable in
loadrunner controller?
During the goal oriented
scenario profile creation, you have to select the appropriate option
for continuation or termination of load test, if the goal is not
achievable.
There are two options available to choose for
non-achievable goals:
Stop scenario and save
results. Instructs the
Controller to stop the scenario and save the scenario results, if the target
you defined cannot be reached.
Continue scenario without reaching goal. Instructs the Controller to continue
running the scenario, even if the target you defined cannot be reached.
If you want to get notified during the goal
oriented scenario, if the goal is not reachable. Select the option
Receive notification. Instructs the Controller to send you an error message indicating that the target cannot be reached.
Receive notification. Instructs the Controller to send you an error message indicating that the target cannot be reached.

There are two types of
schedules available in scenario. Those are
1) Schedule by scenario
schedule the scenario to start running at a specified time. You can
limit the execution duration of the scenario or of a Vuser group within the
scenario.
You can also stipulate how many
Vusers to start and stop running within
a certain time frame. You can specify whether LoadRunner should start or stop running all Vusers in a scenario
simultaneously, or only a certain number of Vusers within a specified amount of
time.
2) Schedule by group
For each enabled Vuser group in
a scenario, you can design a separate execution schedule. You can specify when to start running the Vuser group, how many
Vusers to start and stop
running within given time
intervals, and how long the Vuser group should continue running.
Scenario creation types can be seen
with the link What are the types of run modes
available in loadrunner controller scenario schedule?
For each of the above, the run
modes are:
1) Run by Real
word schedule
The scenario runs according to a user-defined group of actions that simulate a real-world schedule of events. Vuser groups run according to the iterations defined in their run-time settings, but you can define how many Vusers to run at a time, how long Vusers should continue to run, and how many Vusers to stop running at a time.

LoadRunner enables you to view
data generated during scenario execution using the online monitors. You specify
the machines that the Controller will monitor during a scenario execution, and
view the data collected by the monitors, using the LoadRunner online graphs.
A primary factor in a
transaction's response time is its resource usage. By monitoring resources
during a scenario run, you can determine why a bottleneck occurred on a
particular machine. LoadRunner's server resource monitors let you keep track of
resources used during a scenario. LoadRunner displays the selected resource
monitors in real time during test execution. You can select the server resource
measurements to monitor both before and during the scenario.
The online monitors are divided
into the following categories:
Run-Time Monitors. Display the number and status
of Vusers participating in the scenario, as well as the number and types of
errors that the Vusers generate.
Transaction Monitors. Display the transaction rate
and response time during scenario execution.
Web Resource Monitors. Provide information about the
number of Web connections, throughput volume, HTTP responses, server retries,
and pages downloaded to the Web servers during the scenario.
System Resource
Monitors. Measure
the Windows, UNIX, Tuxedo, SNMP, and SiteScope resources used during a scenario.
Network Delay Monitor. Displays information about the
network delays on your system.
Firewall Monitor. Measures statistics of the
firewall servers during the scenario.

The default counters or
measures for
windows monitors given by
load runner are:
% Disk Time
(PhysicalDisk _Total)
Disk Time is the percentage of elapsed time that the selected disk drive is busy servicing read or write requests.
Disk Time is the percentage of elapsed time that the selected disk drive is busy servicing read or write requests.
% Processor Time
(Processor _Total)
% Processor Time is the percentage of time that the processor is executing a non-Idle thread. This counter was designed as a primary indicator of processor activity. It is calculated by measuring the time that the processor spends executing the thread of the Idle process in each sample interval, and subtracting that value from 100%. (Each processor has an Idle thread which consumes cycles when no other threads are ready to run). It can be viewed as the percentage of the sample interval spent doing useful work. This counter displays the average percentage of busy time observed during the sample interval. It is calculated by monitoring the time the service was inactive, and then subtracting that value from 100%.

Available MBytes
(Memory)
Available MBytes is the amount of physical memory available to processes running on the computer, in Megabytes, rather than bytes as reported in Memory\\Available Bytes. It is calculated by adding the amount of space on the Zeroed, Free, and Stand by memory lists. Free memory is ready for use; Zeroed memory are pages of memory filled with zeros to prevent later processes from seeing data used by a previous process; Standby memory is memory removed from a process' working set (its physical memory) on route to disk, but is still available to be recalled. This counter displays the last observed value only; it is not an average.

File
Data Operations/sec
(System)
File Data Operations per second is the rate that the computer is issuing Read and Write operations to file system devices. It does not include File Control Operations.
File Data Operations per second is the rate that the computer is issuing Read and Write operations to file system devices. It does not include File Control Operations.
Interrupts/sec
(Processor _Total)
Interrupts/sec is the average number of hardware interrupts the processor is receiving and servicing in each second. It does not include DPCs, which are counted separately. This value is an indirect indicator of the activity of devices that generate interrupts, such as the system clock, the mouse, disk drivers, data communication lines, network interface cards and other peripheral devices. These devices normally interrupt the processor when they have completed a task or require attention. Normal thread execution is suspended during interrupts. Most system clocks interrupt the processor every 10 milliseconds, creating a background of interrupt activity. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.

Page Faults/sec (Memory)
Page Faults/sec is a count of the Page Faults in the processor. A page fault occurs when a process refers to a virtual memory page that is not in its Working Set in main memory. A Page Fault will not cause the page to be fetched from disk if that page is on the standby list, and hence already in main memory, or if it is in use by another process with whom the page is shared.

A Page Fault will not cause the page to be fetched from disk if that page is on the standby list, and hence already in main memory, or if it is in use by another process with whom the page is shared.
Pages/sec (Memory)
Pages/sec is the number of pages read from the disk or written to the disk to resolve memory references to pages that were not in memory at the time of the reference. This is the sum of Pages Input/sec and Pages Output/sec. This counter includes paging traffic on behalf of the system Cache to access file data for applications. This value also includes the pages to/from non-cached mapped memory files. This is the primary counter to observe if you are concerned about excessive memory pressure (that is, thrashing), and the excessive paging that may result.

Pool Nonpaged Bytes
(Memory)
Pool Nonpaged Bytes is the number of bytes in the Nonpaged Pool, a system memory area where space is acquired by operating system components as they accomplish their appointed tasks. Nonpaged Pool pages cannot be paged out to the paging file, but instead remain in main memory as long as they are allocated.

Private Bytes (Process
_Total)
Private Bytes is the current number of bytes this process has allocated that cannot be shared with other processes.
Private Bytes is the current number of bytes this process has allocated that cannot be shared with other processes.
Processor Queue Length
(System)
Processor Queue Length is the instantaneous length of the processor queue in units of threads. This counter is always 0 unless you are also monitoring a thread counter. All processors use a single queue in which threads wait for processor cycles. This length does not include the threads that are currently executing. A sustained processor queue length greater than two generally indicates processor congestion. This is an instantaneous count, not an average over the time interval.

Threads (Objects)
Threads is the number of threads in the computer at the time of data collection. Notice that this is an instantaneous count, not an average over the time interval. A thread is the basic executable entity that can execute instructions in a processor.

Loadrunner diagnostics are used
for profiling the application server code and database server for
identifying the issues at the code or database level.
For example, if there is any
transaction is taking more than expected time. For getting the detailed
information on which of the servers are causing the problem for the high
response time, we use diagnostics.
Using diagnostics we can easily
pin point the problem on the application server, which API is causing the
problem.
Similarly we can also pin point
the problem on the database which of the SQL/SQLs is/are causing
the problem.
Using the multiple run time
settings we can set the common settings for multiple groups at a time.
The multiple run time settings
mode can be chosen with the below mentioned steps:
1) Open the controller scenario
2) Select the multiple groups on the controller
3) Click on the run time settings
4) The dialog box "Modifying Run-Time Settings for Multiple Scripts" opens
1) Open the controller scenario
2) Select the multiple groups on the controller
3) Click on the run time settings

The Modifying Run-Time Settings
for Multiple Scripts will be invoked with the link:- 59. How do you enable multiple run time
settings mode?
Select
a method
for modifying run-time settings of multiple scripts:
Shared RTS. Opens one window containing all
of the run-time settings in blank mode. In this mode, you set only the options
that you would like to modify for all selected scripts. All other run-time
settings remain unchanged.
1) In shared RTS, all the fields will be with blank settings
2) Used for setting common settings
1) In shared RTS, all the fields will be with blank settings
2) Used for setting common settings
Individual RTS. Opens a separate window for
each selected script. In this mode, you modify each script's settings
individually.
1) Individual RTS, all the fields will be with default or initial settings
2) Used for giving individual run time settings for each script
