Abstract
A method of and system for managing diagnostic information is disclosed. The method and system may include creating a data space in volatile memory. The data space may be configured to collect a selected diagnostic information. The selected diagnostic information may include a first diagnostic information from a first source and a second diagnostic information from a second source. The method and system may include collecting in the data space the selected diagnostic information. The method and system may include releasing from the data space at least a portion of the selected diagnostic information in response to a triggering event.
Claims20
A computer-implemented method for managing diagnostic information, the method comprising:
- 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, and
- a 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.
A system for managing diagnostic information, comprising:
- a remote system;
- and
- a host system, at least one of the remote system and the host system including a diagnostic information management module, the diagnostic information management module comprising:
- a data space creation module to allocate a data space in volatile memory configured 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;
- a collection module to receive in the data space the selected diagnostic information, intermix the first and second diagnostic information during a time window preceding an error event, and release at least a portion of the selected diagnostic information when a collection threshold amount of the data space is reached;
- and
- a release module to dump from the data space to a non-volatile memory at least a portion of the selected diagnostic information in response to the error event.
A storage system, comprising:
- a remote system having two or more storage devices;
- and
- a storage controller having a diagnostic information management module, the diagnostic information management module comprising:
- a data space creation module to allocate a data space in volatile memory configured to store a selected diagnostic information, the selected diagnostic information including a diagnostic information from a plurality of sources, the selected diagnostic information being a subset of information recorded by a generalized trace facility recording events of the plurality of sources;
- a collection module to receive in the data space the selected diagnostic information, the selected diagnostic information including a first portion and a second portion, wherein the collection module is configured to selectively overwrite the first portion when a collection threshold amount of the data space is reached, the first portion having a lower priority than the second portion;
- and
- a release module to dump from the data space to a non-volatile memory at least a portion of the selected diagnostic information in response to an error event.
