# Insights from the OpenTelemetry Developer Experience Survey LLMS index: [llms.txt](/llms.txt) --- The OpenTelemetry Developer Experience SIG recently surveyed the community to better understand where the SIG could have the most impact on improving the developer experience. We received 218 responses, which we will use to guide our prioritization of work within the SIG. This post summarizes our findings and where we will focus in the near term. Thank you to all those who participated in the survey! If you are interested in joining us in these efforts or providing additional insights on where you think the developer experience of OpenTelemetry can be improved, please don’t hesitate to reach out. Contact information for the SIG can be found in the Community repo’s list of [Cross-Cutting SIGs](https://github.com/open-telemetry/community/?tab=readme-ov-file#cross-cutting-sigs), and we have a [repository](https://github.com/open-telemetry/sig-developer-experience) of our own on GitHub. ## Key Takeaways The survey responses highlight the need for improved documentation, more in-depth examples and more substantial guidance on debugging, configuring and deploying OpenTelemetry in Production. Below are the main areas of concern: - Documentation: - Documentation is difficult to navigate, requiring users to switch between the OpenTelemetry website and GitHub repositories. Many users report having to piece together information from various sources. - Lack of examples of production usage for both the SDKs and Collector. - Local debugging: - It's difficult to know why exporting isn't working, and if the SDK is dropping data. Better tooling for local debugging would help with troubleshooting. - SDK configuration: - Overall complexity (both configuration and concepts) - SDK configuration is complex, and many users have pointed out that troubleshooting the exporter is the most painful part. - Collector operations: - Debugging guidance on the Collector configuration and its components is needed. OTTL was mentioned a couple of times for being difficult to troubleshoot. ## Detailed Insights ### General Information about Respondents The survey responses came from users, of whom the majority use OpenTelemetry in production (83%) and do not work for a vendor (77.4%). 82% consider their organization to be at an intermediate or advanced phase of their journey with observability. The platforms used leaned towards Kubernetes (68.2%) and AWS (34.6%), with bare metal still making up a respectable percentage (12%). Programming language usage was split between the usual suspects of Go, Java, JavaScript, Python and .NET, but had a wide spread and even languages without official API/SDK implementations, as shown in the second graph below. While those working on backends or operations were the majority of respondents, mobile and browser were represented as well, see the third graph: ![Forms response chart.

However, unclear documentation took the top spot in the three questions related to getting started with manual instrumentation, auto instrumentation and setting up the SDK. In the Collector's case, it took second place to “configuring the processors”. More details on the user experience with documentation can be found in the survey results of the [survey](/blog/2024/otel-docs-survey/) conducted by the End User SIG. ### Collector Usage Getting started with the Collector was shown to lean towards the fairly easy, though based on results for the question asking for problems with operating the Collector and the overall experience question, it seems clear there is a gap between getting started and operating with more complex pipelines or in larger deployments. More on this in the Future Plans section. Interestingly, _collector-contrib_ had a large percentage of the responses to the question, “Which collector do you use?”. Sadly, it is unclear if this is due to being unaware of OCB ([https://github.com/open-telemetry/opentelemetry-collector/tree/main/cmd/builder](https://github.com/open-telemetry/opentelemetry-collector/tree/d25efc7e2f31a3ba5347d0725a22d7bed1b4015d/cmd/builder?from_branch=main)) for building custom images, disinterest in using it or a lack of adequate documentation around its use. ![Forms response chart.

On the other hand, auto-instrumentation was solidly towards being easier to get started with. Despite getting started with auto-instrumentation being relatively straightforward, the results showed that enriching that telemetry was more difficult. ![Forms response chart.

We will now direct some of this feedback to the respective SIGs, work on prototyping some solutions and follow up with the other teams. Thank you again to all those who participated in the survey! Even though the survey is now over, we do still welcome feedback.
