# Vuser graphs

The Vuser graphs help you determine the overall behavior of Vusers during a scenario. The graphs display the Vuser states, the number of Vusers that completed the script, and rendezvous statistics. Use these graphs in conjunction with Transaction graphs to determine the effect of the number of Vusers on transaction response time. For more information, see Transactions graphs.

## Chaos Event graph

Th Chaos Event graph displays the run time for all Gremlin disruption events that ran during the scenario.

Axis | Description
--- | ---
X-axis | Elapsed time since the start of the run.
Y-axis | Event run: 1 means the event is running.

## Rendezvous graph

The Rendezvous graph indicates when Vusers were released from rendezvous points and how many Vusers were released at each point. This helps you understand the transaction performance times.

During a scenario run, you use the rendezvous points to setup multiple Vusers to perform tasks simultaneously. A rendezvous point creates intense user load on the server and enables the measurement of server performance under load. For more information see Rendezvous points in the VuGen Help Center.

Axis | Description
--- | ---
X-axis | The elapsed time since the start of the run.
Y-axis | The number of Vusers that were released from the rendezvous.

Tip: You can compare this graph to the Average Transaction Response Time graph to see how the load peak created by a rendezvous influences transaction times.

## Running Vusers graph

The Running Vuser graph displays the number of Vusers (or active JMeter threads) that executed scripts and their status during each second of the test. This helps you to determine the Vuser load on your server at any given moment.

Axis | Description
--- | ---
X-axis | The elapsed time since the run started.
Y-axis | The number of Vusers in the scenario.

Note: By default, the graph shows only the Vusers with a Run status. To view another Vuser status, set the filter conditions to the preferred status. For more information, see Filter and sort graph data.

## Vuser Summary graph

The Vuser Summary graph displays a summary of Vuser performance. It provides a pie-chart view of the number of Vusers that successfully completed the load test scenario run relative to those that did not.
