When using Percepio TraceRecorder, kernel objects like queues, semaphores and mutexes are named using their address by default. This can be a bit hard to follow for complex traces. However, it is quite easy to set more descriptive custom names for your RTOS kernel objects. This by calling the “SetName” functions (or macros) found in the TraceRecorder API, for example: The first argument is the pointer to the object (i.e. the object address).

About 15 years ago, I worked at a company building network security appliances (with ARM-based network processors) and was responsible for the development of custom Linux firmware. The product launch was successful; we shipped and managed a large fleet of devices in the field. After a few firmware releases, we received alerts from the device management system telling us that there were intermittent problems. Remoted into the appliances but could not reproduce the error.
