On May 29th, 2025, I wrapped up my mentorship with Prometheus through the Linux Foundation Mentorship Program. My project focused on understanding how Prometheus handles OpenTelemetry resource attributes and how that experience could be improved for users. My job was to conduct user research to get the user perspective on this challenge. In three months, I conducted user and stakeholder interviews, ran a survey, and analyzed the findings. In this article, I’ll share how I conducted the rese...| OpenTelemetry
While OpenTelemetry (OTel) is here to help you with troubleshooting and handling the “unknown unknowns”, it is also instrumental for managing route tasks like monitoring system metrics, like disk usage, server availability or SSL certificate expiration dates. This can be achieved by utilizing any one of the 90+ receivers available for the OpenTelemetry Collector, such as the Host Metrics Receiver or the HTTP Check Receiver. But what if the available receivers don’t meet your specific ne...| OpenTelemetry
In the following, we will walk through how to do logs collection with OpenTelemetry (OTel). To keep things simple, we will use Python as the demonstration programming language, however note that at time of writing the logs support there is still early days so things might need some updating. We will show the evolution from using print statements for logging (Baby Grogu level) to logging to a file along with the OpenTelemetry Collector (Expert Grogu level) to using the OTel logs bridge API to ...| OpenTelemetry
OTel integration! Cloud Foundry recently integrated the OpenTelemetry Collector for metrics egress and we learned a lot along the way. We’re excited about what the integration offers today and all the possibilities it opens up for us. What we were looking for Cloud Foundry is a large multi-tenant platform as a service that runs 12-factor applications. Cloud Foundry platform engineering teams usually run 4 to 8 Cloud Foundry deployments running thousands of applications and hundreds of thous...| OpenTelemetry
