Tracking errors in a computing system

1. An apparatus for tracking errors in a computing system that includes a plurality of current error buckets and a plurality of historical error buckets, the apparatus comprising a hardware computer processor, a hardware computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

inserting, by an error repository manager into a current error bucket, error information describing a first error identified by a timestamp, wherein the current error bucket is associated with a bucket interval determined using a base time interval associated with the error measured from the timestamp;

moving, by the error repository manager, the error information in the current error bucket to a historical error bucket upon the expiration of the bucket interval, wherein each historical error bucket has a storage interval determined in dependence upon the base time interval associated with the error and a bucket number associated with the historical error bucket; and

moving, by the error repository manager, the error information in a source historical error bucket to a destination historical error bucket upon the expiration of the storage interval associated with the source historical error bucket.

2. The apparatus of claim 1 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the step of inserting, by an error repository manager into the current error bucket, error information describing a next error occurring within the bucket interval.

3. The apparatus of claim 1 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

determining, by the error repository manager, the number of errors in the current error bucket;

determining, by the error repository manager, whether the number of errors in the current error bucket exceeds a predetermined threshold; and

responsive to determining that the number of errors in the current error bucket exceeds the predetermined threshold, sending, by the error repository manager, an alert.

4. The apparatus of claim 1 wherein error information describing an error includes a timestamp.

5. The apparatus of claim 1 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

receiving, by the error repository manager, a new base time interval; and

determining, by the error repository manager for each historical error bucket, a new storage interval determined in dependence upon the new base time interval and the bucket number associated with the historical error bucket.

6. A computer program product for tracking errors in a computing system that includes a plurality of current error buckets and a plurality of historical error buckets, the computer program product disposed upon a non-transitory computer readable medium, the computer program product comprising computer program instructions that, when executed, cause a computer to carry out the steps of:

inserting, by an error repository manager into a current error bucket, error information describing a first error identified by a timestamp, wherein the current error bucket is associated with a bucket interval determined using a base time interval associated with the error measured from the timestamp;

moving, by the error repository manager, the error information in the current error bucket to a historical error bucket upon the expiration of the bucket interval, wherein each historical error bucket has a storage interval determined in dependence upon the base time interval associated with the error and a bucket number associated with the historical error bucket; and

moving, by the error repository manager, the error information in a source historical error bucket to a destination historical error bucket upon the expiration of the storage interval associated with the source historical error bucket.

7. The computer program product of claim 6 further comprising computer program instructions that, when executed, cause the computer to carry out the step of inserting, by an error repository manager into the current error bucket, error information describing a next error occurring within the bucket interval.

8. The computer program product of claim 6 further comprising computer program instructions that, when executed, cause the computer to carry out the steps of:

determining, by the error repository manager, the number of errors in the current error bucket;

determining, by the error repository manager, whether the number of errors in the current error bucket exceeds a predetermined threshold; and

responsive to determining that the number of errors in the current error bucket exceeds the predetermined threshold, sending, by the error repository manager, an alert.

9. The computer program product of claim 6 wherein error information describing an error includes a timestamp.

10. The computer program product of claim 6 further comprising computer program instructions that, when executed, cause the computer to carry out the steps of:

receiving, by the error repository manager, a new base time interval; and

determining, by the error repository manager for each historical error bucket, a new storage interval determined in dependence upon the new base time interval and the bucket number associated with the historical error bucket.

11. The computer program product of claim 6 wherein the computer readable medium comprises a storage medium.
