An error logging system is provided that is configured to automatically create a type introspection database from a compiled application that was written using the C programming language. During execution of the application, if there is an error, the executing application will generate an unstructured error log which is passed to an error logging system. The type introspection database enables the error logging system to parse the unstructured error log to create a corresponding structured error log. The error logging system includes generic display, search, and share functions. The display function is configured to display the name, value, and type, of every attribute in each data structure. The search function provides a way to determine if the structured error log satisfies a selection criteria specified on one or more attributes of the data. The share function enables the error logging system to export the structured error logs.

Controlling I/O operations with a storage device includes establishing a quota that corresponds to a maximum amount of data to store on the storage device in a given amount of time, determining if processing an I/O operation would cause the quota to be exceeded, and performing the I/O operation if the quota is not exceeded. The quota may be provided in I/O operations per second or as I/O throughput. Controlling I/O operations with a storage device may also include accumulating credit in response to a rate of I/O operations being less than the quota and performing I/O operations when the quota is exceeded in response to the credit being greater than zero. The credit may be decreased if an I/O operation is performed when the quota is exceeded.
