Available Graphs Tree

The Available Graphs Tree displays the online monitor graphs.

Tip: Graph names that are displayed in blue in the list of Available Graphs, contain data.

To select measurements to monitor in a particular graph, see the monitor configuration instructions for each specific monitor. For details, see How to Set Up a Monitoring Environment.

Graph
Description
Running Vusers
Provides information about the status of the Vusers running in the current scenario on all load generators. The graph shows the number of running Vusers, while the information in the legend indicates the number of Vusers in each state.
User-Defined Data Points
Displays the real-time values of user-defined data points. You define a data point in your Vuser script by inserting an lr_user_data_point function at the appropriate place (user_data_point for GUI Vusers and lr.user_data_point for Java Vusers).
Error Statistics
Provides details about the number of errors that accrue during each second of the scenario run. The errors are grouped by error source—for example, the location in the script or the load generator name.
Vusers with Errors
Provides details about the number of Vusers that generate errors during scenario execution. The errors are grouped by error source.
Transaction Response Time
Shows the average response time of transactions in seconds (y-axis) as a function of the elapsed time in the scenario (x-axis).
Transaction Response Time by Location

Shows the average transaction response time (y-axis) for each of the virtual locations with which the transactions were performed (x-axis).

Transaction Per Second (Passed)
Shows the number of successful transactions performed per second (y-axis) as a function of the elapsed scenario time (x-axis).
Transaction Per Second (Passed) by Location
Shows the number of successful transactions performed per second (y-axis) as a function of the elapsed time in the scenario (x-axis), broken down by location.
Transaction Per Second (Failed, Stopped)
Shows the number of failed and stopped transactions per second (y-axis) as a function of the elapsed scenario time (x-axis).
Transaction Per Second (Failed, Stopped) by Location
Shows the number of failed and stopped transactions per second (y-axis) as a function of the elapsed scenario time (x-axis), broken down by location.
Total Transactions Per Second (Passed)
Shows the total number of completed, successful transactions per second (y-axis) as a function of the elapsed scenario time (x-axis).
Hits Per Second
Shows the number of hits (HTTP requests) to the Web server (y-axis) as a function of the elapsed time in the scenario (x-axis). You can compare this graph to the Transaction Response Time graph to see how the number of hits affects transaction performance.
Throughput
Shows the amount of throughput on the Web server (y-axis) during each second of the scenario run (x-axis). Throughput is measured in bytes and represents the amount of data that the Vusers received from the server at any given second. You can compare this graph to the Transaction Response Time graph to see how the throughput affects transaction performance.
HTTP Responses per Second
Shows the number of HTTP status codes—which indicate the status of HTTP requests, for example, "the request was successful," "the page was not found"—(y-axis) returned from the Web server during each second of the scenario run (x-axis), grouped by status code. You can group the results shown in this graph by script (using the "Group By" function) to locate scripts which generated error codes.
WebSocket Statistics Provides statistics for the WebSocket data during the scenario run, such as byte rate, connection status, and the number of messages.
Pages Downloaded per Second
Shows the number of Web pages (y-axis) downloaded from the server during each second of the scenario run (x-axis). This graph helps you evaluate the amount of load Vusers generate, in terms of the number of pages downloaded.
Retries per Second
Shows the number of attempted Web server connections (y-axis) as a function of the elapsed time in the scenario x-axis). A server connection is retried when the initial connection was unauthorized, when proxy authentication is required, when the initial connection was closed by the server, when the initial connection to the server could not be made, or when the server was initially unable to resolve the load generator's IP address.
Connections
Shows the number of open TCP/IP connections (y-axis) at each point in time of the scenario (x-axis). One HTML page may cause the browser to open several connections, when links on the page go to different Web addresses. Two connections are opened for each Web server.
Connections per Second
Shows the number of new TCP/IP connections (y-axis) opened and the number of connections that are shut down each second of the scenario (x-axis).
SSLs per Second
Shows the number of new and reused SSL Connections (y-axis) opened in each second of the scenario (x-axis). An SSL connection is opened by the browser after a TCP/IP connection has been opened to a secure server.
Windows Resources
Shows the NT and Windows 2000 resources measured during the scenario. The NT and Windows 2000 measurements correspond to the built-in counters available from the Windows Performance Monitor.
UNIX Resources
Shows the Linux resources measured during the scenario. The Linux measurements include those available by the rstatd daemon: average load, collision rate, context switch rate, CPU utilization, incoming packets error rate, incoming packets rate, interrupt rate, outgoing packets error rate, outgoing packets rate, page-in rate, page-out rate, paging rate, swap-in rate, swap-out rate, system mode CPU utilization, and user mode CPU utilization.
SNMP
Shows statistics for machines running an SNMP agent, using the Simple Network Management Protocol (SNMP). The x-axis represents the elapsed time. The y-axis represents the resource usage.
Network Delay Time
Shows the delays for the complete path between the source and destination machines (for example, the database server and Vuser load generator). The graph maps the delay as a function of the elapsed scenario time.
Apache
Displays statistics about the resource usage on the Apache server during the scenario run. The x-axis represents the time that has elapsed since the start of the scenario run. The y-axis represents the resource usage.
Microsoft IIS
Shows server statistics as a function of the elapsed scenario time. The x-axis represents the time that has elapsed since the start of the scenario run. The y-axis represents the resource usage.
Microsoft Active Server Pages
Displays statistics about the resource usage on the ASP server during the scenario run. The x-axis represents the time that has elapsed since the start of the scenario run. The y-axis represents the resource usage.
Oracle
Displays information from Oracle V$ tables: Session statistics, V$SESSTAT, system statistics, V$SYSSTAT, and other table counters defined by the user in the custom query.
SQL Server
Shows the standard Windows resources on the SQL server machine. The x-axis represents the time that has elapsed since the start of the scenario run. The y-axis represents the resource usage.

MQTT Statistics Graphs Provide statistics about MQTT message flow and throughput between the MQTT broker and the client during the scenario run. For details, see MQTT Statistics Monitoring.
Streaming State Statistics Graphs

Provide statistics about the streaming videos in the scenario run. For details, see Streaming State Statistics Monitoring.

TruClient Native Mobile Provide statistics about CPU utilization memory on a mobile device during a scenario run. For details, see TruClient - Native Mobile Monitors.
Network Virtualization Graphs Graphs that show information about the Network Virtualization: Average Latency, Packet Loss, Average Throughput, Average Bandwidth Utilization, and Total Throughput. For details, see Network Virtualization Monitoring.
HPE Service Virtualization
Shows statistics of the service virtualization, showing the Operations and Services graphs. For details, see Service Virtualization Integration.
SiteScope
Displays statistics about the resource usage on the SiteScope machine during the scenario run. The x-axis represents the elapsed time. The y-axis represents the resource usage.
