Patent ID: 8108363

Claim:
A computer-readable medium that stores therein a computer program that causes a computer to analyze a processing state of a computer system that includes a plurality of types of a unit of processing, wherein the computer program causes the computer to execute: selecting a plurality of representative units of processing based on a weighted edit distance between individual units of the unit of processing, the unit of processing including one of protocol types that indicate protocol information, an edit distance between a first string: p and a second string: q being a number of minimum operations to be performed on the first string: p to correspond the first string: p with the second string: q, the weighted edit distance ed(p, q) being defined as: ed(p, q)=(edit distance between p and q)/(sum of string lengths of p and q), when p and q use a same protocol, the weighted edit distance ed(p, q) being defined as: ed(p, q)=(constant value), when p and q use different protocols from each other; grouping each unit of processing based on the weighted edit distance between the each unit of processing and each representative unit of processing selected at the selecting; and monitoring a processing state of the computer system using at least one of the representative units of processing selected at the selecting.
