An event chain visualization of performance data may show the execution of monitored elements as bars on a timeline, with connections or other relationships connecting the various bars into a sequential view of an application. The visualization may include color, shading, or other highlighting to show resource utilization or performance metrics. The visualization may be generated by monitoring many events processed by an application, where each bar on a timeline may reflect multiple instances of a monitored element and, in some case, the aggregated performance.
