performance of your Web server using Load Runner’s Web Resource monitor.

What is Web Resource Monitoring?
The Web Resource monitor to provide the power of you, to analyze the output on the web server, and the number of push (hits) per second that
occurred during the scenarios, or the number of HTTPs reactions per second, and
the HTTP’s status codes returned from Web server, & the number of
downloaded pages per second, or the number of server re-tries per second, the
number of opens TCP/IP connection’s, the number of new TCP/IP connection’s per
second, and the number of SSLs Connection per second.
Hit per Second Graphs
The Hits of per Second graph displays the number of hits to
the Web server as the function of passed time in the scenarios. This graph can show
the full step, & the last 60, 180, 600, and 3600 seconds. You can proportion
this graph to the (Transaction Response Time) graph to look how the number of hits
affects to the transaction performance.
Throughput of the Graph
The capacity of the graph shows the amount
of throughput on the Web server during every second of the scenarios executes.
Throughput is also measured in bytes or represents the amount of information’s
that user’s received from the server at any given second. You can proportion
this graph to Transaction Response Time graph to view, how the throughput
affects to the transaction performance.
Re-tries per Second Graph
Retries per Second graph displays the number of the attempted
Web server connections as a function of the passed time in the scenarios. A
server connection is re-tried when the starting connection was un-authorized,
and when proxy authentication is needed, when the starting connection was
closed through the server, when the opening connection to the server could not
be made, and when the server was initially incapable to resolve the load
generators’ IP addresses.
Connections to the Graph
Connections graph displays the number of opens TCP/IP
connections at all points in the time of scenarios. One the HTML page may reason
of the browser to opens the several connections, when links on the pages go to the
different Web addresses. The two connections are opened for all Web servers.
This graph is very useful in pointing, when additional connections are required.
Connection per Second Graph
A Connection per Second graph displays the number of new
TCP/IP connections opened & the number of connection’s that are shut down every
second of the scenarios. This number should be in small fractions of the number
of hits per second, because the new TCP/IP connection is very expensive in terms
of servers, router or network resource consumptions. Ideally, many of HTTP
requests should use the common connections, instead of initially a new
connection for all requests.
Secured Sockets Layer (SSL) connections per second
Number of SSL connections opened per second, after TCP/IP
connections of SSL connection is opened. SSLs connection has bulky (heavy) resources
consumptions. If we selects the, simulate a new user at every iteration then
there should not be more than of one SSL connection per second.
