5. The method of claim 1 wherein determining that the logging level for the component should be changed further comprises evaluating results from a health check of the storage system.
6. The method of claim 1 , wherein the measured performance characteristics of the storage system includes the amount of data transferred to service I/O operations directed to the storage system during a predetermined period of time.
7. The method of claim 1 , wherein the measured performance characteristics of the storage system includes the average response time taken to service I/O requests directed to the storage system.
8. A method comprising:
receiving log data from a storage system;
determining, in dependence upon one or more measured performance characteristics of the storage system, whether the logging level for a component of a plurality of components within the storage system should be changed including detecting that one or more performance-related characteristics of the storage system matches a predetermined fingerprint, the logging level specifying the extent to which log data should be generated for a particular component, wherein the component comprises a hardware component, wherein the determination further comprises determining, for each of the plurality of components, that the logging level should be changed, including detecting that a predetermined amount of time has lapsed since an error has been encountered by each respective component within the storage system; and
responsive to determining that the logging level for the component should be changed, changing the logging level associated with the component.
9. The method of claim 8 wherein determining that the logging level for the component should be changed further comprises detecting that an error has been encountered by one or more components in the storage system.
10. The method of claim 8 wherein detecting that one or more performance characteristics of the storage system matches a predetermined performance characteristic fingerprint further comprises comparing log data generated by the storage system to one or more operating characteristic fingerprints.
11. The method of claim 8 wherein determining that the logging level for the component should be changed further comprises evaluating results from a health check of the storage system.
12. An apparatus comprising a computer processor, a 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 processor of the apparatus to carry out the steps of:
determining, in dependence upon one or more measured performance characteristics of the storage system, whether a logging level for a component of a plurality of components within the storage system should be changed including detecting that one or more performance-related-characteristics of a storage system matches a predetermined fingerprint, the logging level specifying the extent to which log data should be generated for a particular component, wherein the component comprises a hardware component, wherein the determination further comprises determining, for each of the plurality of components, that the logging level should be changed, including detecting that a predetermined amount of time has lapsed since an error has been encountered by each respective component within the storage system; and
responsive to determining that the logging level for the component should be changed, changing the logging level associated with the component.
13. The apparatus of claim 12 further comprising computer program instructions that, when executed by the computer processor, cause the processor of the apparatus to carry out the step of receiving log data from the storage system.
14. The apparatus of claim 12 further comprising computer program instructions that, when executed by the computer processor, cause the processor of the apparatus to carry out the steps of setting, by the storage system services provider, for a component within the storage system, a logging level for the component, the logging level specifying the extent to which log data should be generated for a particular component.
15. The apparatus of claim 12 wherein determining that the logging level for the component should be changed further comprises detecting that an error has been encountered by one or more components in the storage system.
16. The apparatus of claim 12 wherein detecting that one or more performance characteristics of the storage system matches a predetermined performance characteristic fingerprint further comprises comparing log data generated by the storage system to one or more fingerprints.
17. The apparatus of claim 12 wherein determining that the logging level for the component should be changed further comprises evaluating results from a health check of the storage system.
18. The apparatus of claim 12 wherein determining, in dependence upon one or more measured performance characteristics of the storage system, that the logging level for the component should be changed further comprises detecting that a predetermined amount of time has lapsed since an error has been encountered by one or more components in the storage system.
