## Abstract

An analysis device for analyzing services on a network includes: a storage unit configured to store, maintenance information collected, from the network, at a predetermined time interval and for each of the services, application rules describing a technique for applying a plurality of types of analysis logics classified by use, and a catalog describing specifications of the analysis logics; a rule application unit configured to, upon receipt of a request related to an analysis target service, apply the maintenance information over a predetermined period of the analysis target service to the application rules; an analysis logic selection unit configured to select the analysis logics for each use based on a result of the application to the application rules; and a collaborative catalog generation unit configured to generate a collaborative catalog including a combination of the catalogs describing the specifications of the selected analysis logics.

## Claims

### Claim 1

An analysis device for analyzing services on a network, the analysis device comprising:
a storage unit configured to store i) maintenance information collected, from the network, at a predetermined time interval and for each of the services, ii) application rules each describing a technique for applying a plurality of types of analysis logics classified by use, and iii) a catalog describing specifications of the plurality of types of analysis logics;
a rule application unit configured to, upon receipt of a request related to an analysis target service, apply the maintenance information over a predetermined period of the analysis target service to the application rules;
an analysis logic selection unit configured to select the analysis logics for each use based on a result of the application to the application rules; and
a collaborative catalog generation unit configured to generate a collaborative catalog including a combination of the catalogs describing the specifications of the selected analysis logics.

### Claim 2 (depends on 1)

The analysis device according to claim 1, wherein:
the catalog is a catalog describing the specifications of the analysis logics for an abnormality determination of the analysis target service,
the analysis logics are classified into a preprocessing logic, a score value calculation logic, and a threshold calculation logic, and
the application rules are classified into a preprocessing application rule, a score value calculation application rule, and a threshold calculation application rule.

### Claim 3 (depends on 1)

The analysis device according to claim 1, wherein:
the catalog is a catalog describing the specifications of the analysis logics for a demand prediction of the analysis target service,
the analysis logics are classified into a preprocessing logic, a model calculation logic, and a future value calculation logic, and
the application rules are classified into a preprocessing application rule, a model calculation application rule, and a future value calculation application rule.

### Claim 4

An analysis method performed by an analysis device for analyzing services on a network, wherein
a storage unit of the analysis device stores i) maintenance information collected, from the network, at a predetermined time interval and for each of the services, application rules each describing a technique for applying a plurality of types of analysis logics classified by use, and iii) a catalog describing specifications of the plurality of types of analysis logics, and the analysis device executes the method comprising:
upon receipt of a request related to an analysis target service, applying the maintenance information over a predetermined period of the analysis target service to the application rules;
selecting the analysis logics for each use based on a result of the application to the application rules; and
generating a collaborative catalog including a combination of the catalogs describing the specifications of the selected analysis logics.
