Storing changes made toward a limit

A computer-readable storage medium encoded with instructions, wherein the instructions when executed comprise:

• registering at least one limit record associated with a limited variable used by a program, each limit record containing a respective program identifier identifying the respective program which uses the respective limited variable with which the limit record is associated, a respective limit identifier identifying the respective limited variable with which the limit record is associated, a respective minimum value, and a respective increment value, the respective minimum value and the respective increment value specifying respective quantitative values associated with the respective limited variable used by the program;
• in response to storing a data value to a stored variable during execution of an executing program, determining whether the executing program and stored variable correspond to a respective program and respective limited variable specified by a previously registered limit record;
• responsive to determining that the executing program and stored variable correspond to a respective program and respective limited variable specified by a previously registered limit record, determining whether the data value that was stored to the stored variable is greater than the respective minimum value specified by the previously registered limit record and a metric of recent change in the data value that was stored to the stored variable exceeds the respective increment value specified by the previously registered limit record;
• responsive to determining that the data value that was stored to the stored variable is greater than the respective minimum value specified by the previously registered limit record and the metric of recent change in the data value that was stored to the stored variable exceeds the respective increment value specified by the previously registered limit record, storing the data value that was stored to the stored variable to a log associated with the previously registered limit record;
• and
• wherein the metric of recent change in the data value that was stored to the stored variable is based at least in part on a previously stored data value in the log associated with the previously registered limit record.

A computer comprising:

• a processor;
• and
• memory communicatively coupled to the processor, wherein the memory is encoded with instructions, wherein the instructions when executed by the processor comprise
• registering at least one limit record associated with a limited variable used by a program, each limit record containing a respective program identifier identifying the respective program which uses the respective limited variable with which the limit record is associated, a respective limit identifier identifying the respective limited variable with which the limit record is associated, a respective minimum value, and a respective increment value, the respective minimum value and the respective increment value specifying respective quantitative values associated with the respective limited variable used by the program,
• in response to storing a data value to a stored variable during execution of an executing program, determining whether the executing program and stored variable correspond to a respective program and respective limited variable specified by a previously registered limit record,
• responsive to determining that the executing program and stored variable correspond to a respective program and respective limited variable specified by a previously registered limit record, determining whether the data value that was stored to the stored variable is greater than the respective minimum value specified by the previously registered limit record and a metric of recent change in the data value that was stored to the stored variable exceeds the respective increment value specified by the previously registered limit record,
• responsive to determining that the data value that was stored to the stored variable is greater than the respective minimum value specified by the previously registered limit record and the metric of recent change in the data value that was stored to the stored variable exceeds the respective increment value specified by the previously registered limit record, storing the data value that was stored to the stored variable to a log associated with the previously registered limit record;
• and
• wherein the metric of recent change in the data value that was stored to the stored variable is based at least in part on a previously stored data value in the log associated with the previously registered limit record,
• responsive to determining that the executing program and stored variable correspond to a respective program and respective limited variable specified by a previously registered limit record, determining whether the data value that was stored to the stored variable is greater than the respective minimum value specified by the previously registered limit record and a most recently logged data value does not exist in the log associated with the previously registered limit record, and
• responsive to determining that the data value that was stored to the stored variable is greater than the respective minimum value specified by the previously registered limit record and a most recently logged data value does not exist in the log associated with the previously registered limit record, storing the data value that was stored to the stored variable to the log associated with the previously registered limit record.
