 zPages are an in-process alternative to external exporters. When included, they collect and aggregate tracing and metrics information in the background; this data is served on web pages when requested.
 
-The idea of "zPages" originates from one of OpenTelemetry's predecessors, [OpenCensus](https://opencensus.io/). You can read more about zPages from the OpenCensus docs [here](https://opencensus.io/zpages) or the OTEP [here](https://github.com/open-telemetry/oteps/blob/master/text/0110-z-pages.md). OpenCensus has different zPage implementations in [Java](https://opencensus.io/zpages/java/), [Go](https://opencensus.io/zpages/go/), and [Node](https://opencensus.io/zpages/node/) and there has been similar internal solutions developed at companies like Uber. Within OpenTelemetry, zPages are also either developed or being developed in [C#](https://github.com/open-telemetry/opentelemetry-dotnet/tree/master/src/OpenTelemetry.Exporter.ZPages), Java, and C++. The OTel Collector also has [an implementation](https://github.com/open-telemetry/opentelemetry-collector/tree/master/extension/zpagesextension) of zPages.

The OTel Collector also has [an implementation](https://github.com/open-telemetry/opentelemetry-collector/tree/master/extension/zpagesextension) of zPages.
 
 zPages are uniquely useful in a couple of different ways. One is that they're more lightweight and quicker compared to installing external tracing systems like Jaeger and Zipkin, yet they still share useful ways to debug and gain insight into instrumented applications; these uses depend on the type of zPage, which is detailed below. For high throughput applications, zPages can also analyze more telemetry with the limited set of supported scenarios than external exporters; this is because zPages are in-memory while external exporters are typically configured to send a subset of telemetry for reach analysis to save costs.
