To instrument LimitRanges in Kubernetes with OpenTelemetry, you can utilize the OpenTelemetry Collector to monitor resources dynamically. This includes setting up the proper instrumentation to ensure metrics related to resource limits are captured and analyzed. Below is an example of how you can achieve this using OpenTelemetry with the appropriate configuration to instrument LimitRanges effectively.
// Example configuration for OpenTelemetry Collector
