1. A computer program product for managing diagnostic information, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions to cause:
allocating a data space in a volatile memory to store a selected diagnostic information, the selected diagnostic information including a first diagnostic information from a first source and a second diagnostic information from a second source, the selected diagnostic information being a subset of information recorded by a generalized trace facility recording events of the first and second sources; collecting in the data space the selected diagnostic information, the collecting including:
an intermixing of the first diagnostic information and the second diagnostic information during a time window preceding an error event, anda wrapping in the data space of at least a portion of the selected diagnostic information when a collection threshold amount of the data space is reached; and dumping from the data space to a non-volatile memory at least a portion of the selected diagnostic information in response to the error event.
