Abstract

A technique for interactively analyzing system log-files. System log-files, which are monitored by technical personnel and systems specialists to determine system performance, status, and software faults, are often generated during various hardware and software monitoring operations. Each log-file contains time stamped reports. This technique is especially useful for analyzing large log-files. A new release of software may contain many incremental versions that must be tested. The testing of each incremental version may generate a log-file containing thousands of reports. Using this technique, reports are correlated, faults are isolated, and temporal patterns are recognized more quickly and efficiently than by using conventional, non-graphical techniques.

Claims

1. Apparatus comprising:

means for originating a plurality of time-stamped messages, each message having a set of characteristics;

means for visually displaying a plurality of symbols, each symbol corresponding to a respective message of said plurality of messages;

each symbol having an appearance that varies according to a first characteristic of the set of characteristics of its respective message;

each symbol having a position that is determined by the time-stamp and a second characteristic of the set of characteristics of its respective message; and

means for displaying the message corresponding to any symbol.

2. The apparatus according to claim 1, wherein values of said characteristic are monotonically ordered.

3. The apparatus according to claim 1, wherein:

each symbol is a line-segment of varying inclination and varying color.

4. The apparatus according to claim 1, wherein:

each symbol is a line-segment varying in inclination, color and texture.

5. The apparatus according to claim 1, wherein:

each symbol is a geometric shape varying in color.

6. The apparatus according to claim 1, wherein:

each symbol is a geometric shape varying in texture.

7. The apparatus according to claim 1, wherein:

each symbol is a geometric shape varying in color and texture.

8. The apparatus according to claim 1, further comprising means for searching the message for a textual pattern.

9. The apparatus according to claim 1, further comprising means for displaying a total of occurrences of messages of a specific type.

10. The apparatus according to claim 9, wherein said time interval is adjustable.

11. The apparatus according to claim 1, further comprising means for displaying a total of all messages time stamped within a time interval.

12. The apparatus according to claim 11, wherein said time interval is adjustable.

13. The apparatus according to claim 1, further comprising means for displaying a selector window that allows selected values of an attribute to not be displayed.

14. Apparatus comprising:

a processor;

a random access memory;

a mass storage device having a plurality of unprocessed log file messages stored therein;

a relational data base process performed by said processor to process said plurality of unprocessed log file messages into a set of relations stored in said random access memory; and

display means for visually displaying non-textual geometric representations of said relations derived from said plurality of log file messages.

15. A method comprising the steps of:

originating a plurality of time-stamped messages, each message having a set of characteristics;

visually displaying a plurality of symbols, each symbol corresponding to a respective message of said plurality of messages, each symbol having an appearance that varies according to a characteristic of its respective message;

locating each symbol at a position that is determined by its respective time-stamp and a second characteristic of its respective message;

selecting one of said plurality of symbols; and

displaying the message corresponding to said selected symbol.

16. Apparatus comprising:

means for originating a plurality of time-stamped messages, each message having a set of characteristics;

means for visually displaying a plurality of symbols, each symbol corresponding to a respective message of said plurality of messages;

each symbol having an appearance that varies according to a first characteristic of the set of characteristics of its respective message;

each symbol having a position that is determined by the time-stamp and a second characteristic of the set of characteristics of its respective message; and

means for turning off the displaying of all symbols except those having a characteristic that they are from a selected module.

17. The apparatus according to claim 16, wherein said selected module is a processor module.
