Abstract

Monitoring apparatus is configured to execute: obtaining pieces of information about access in a first time slot by specifying the first time slot including access to a first apparatus in the system where a response time is long; selecting a feature common to the access in the first time slot from the pieces of information about the access in the first time slot that have been obtained; first extracting from pieces of information about access in a given period of time, pieces of information about access that has the common feature selected as a feature common to the access in the first time slot; and first generating a first graph which shows changes with time in response time, based on the pieces of information about the access having the feature common to the access in the first time slot that have been extracted.

First claim

What is claimed is:

1 . A monitoring apparatus for monitoring a system, comprising:
a processor for executing a program; a memory for storing the program that is executed by the processor; and an interface for controlling communication between the monitoring apparatus and the system, wherein the processor is configured to execute:
obtaining pieces of information about access in a first time slot by specifying the first time slot including access to a first apparatus in the system where a response time is long;
selecting a feature common to the access in the first time slot from the pieces of information about the access in the first time slot that have been obtained at the obtaining;
first extracting from pieces of information about access in a given period of time, pieces of information about access that has the common feature selected at the selecting as a feature common to the access in the first time slot; and
first generating a first graph which shows changes with time in response time, based on the pieces of information about the access having the feature common to the access in the first time slot that have been extracted at the first extracting.

2 . The monitoring apparatus according to claim 1 , wherein the processor is further configured to:
obtain pieces of information about access in the first time slot that has a long response time at the obtaining; select a feature common to the access that has a long response time from the pieces of information about the access that has a long response time at the selecting; extract from pieces of information about access in the given period of time, pieces of information about access that has the common feature selected at the selecting as a feature common to the access that has a long response time at first extracting; and generate the first graph which shows changes with time in response time based on the pieces of information that have been extracted at the first extracting as pieces of information about the access having the feature common to the access that has a long response time at first generating.

3 . The monitoring apparatus according to claim 1 , wherein the given period of time comprises a period in which the first apparatus is free from experiencing a failure.

4 . The monitoring apparatus according to claim 1 , wherein the processor is further configured to execute:
second extracting pieces of information about requests in a second time slot from pieces of information about requests that have been processed by a second apparatus in the system on demand from the first apparatus, by specifying, on the first graph generated at the first generating, the second time slot including access having a long response time; third extracting, from pieces of information about requests in the given period of time, pieces of information about the same requests as those of the pieces of information about requests in the second time slot that at the second extracting; and second generating, for each request, a second graph which shows changes with time in execution time required for the request processing in the second apparatus, based on the pieces of information about requests that have been extracted at the third extracting.

5 . The monitoring apparatus according to claim 4 , wherein the processor is further configured to extract, at the second extracting, pieces of information about requests in the second time slot that have a long execution time from the pieces of information about requests that have been processed by the second apparatus on demand from the first apparatus.

6 . The monitoring apparatus according to claim 4 , wherein the given period of time comprises a period in which the second apparatus is free from experiencing a failure.

7 . The monitoring apparatus according to claim 1 , wherein the processor is further configured to obtain, at the obtaining, pieces of information about access in the first time slot by specifying the first time slot including access to the first apparatus where the response time has exceeded a baseline.

8 . A monitoring method, which is to be executed by a monitoring apparatus for monitoring a system,
the monitoring apparatus comprising:
a processor for executing a program;
a memory for storing the program that is executed by the processor; and
an interface for controlling communication between the monitoring apparatus and the system,
the monitoring method comprising: obtaining, by the processor, pieces of information about access in a first time slot by specifying the first time slot including access to a first apparatus in the system where a response time is long; selecting, by the processor, a feature common to the access in the first time slot from the pieces of information about the access in the first time slot that have been obtained at the obtaining; first extracting, by the processor, from pieces of information about access in a given period of time, pieces of information about access that has the common feature selected at the selecting as a feature common to the access in the first time slot; and first generating, by the processor, a first graph which shows changes with time in response time, based on the pieces of information about the access having the feature common to the access in the first time slot that have been extracted at the first extracting.

9 . A non-transitory recording medium having stored thereon a program to be executed by a processor, the non-transitory recording medium being readable by the processor, the non-transitory recording medium having recorded thereon a monitoring program for controlling the processor to execute:
obtaining pieces of information about access in a first time slot by specifying the first time slot including access to a first apparatus in the system where a response time is long; selecting a feature common to the access in the first time slot from the pieces of information about the access in the first time slot at the obtaining; first extracting, from pieces of information about access in a given period of time, pieces of information about access that has the common feature selected at the selecting as a feature common to the access in the first time slot; and first generating a first graph which shows changes with time in response time, based on the pieces of information about the access having the feature common to the access in the first time slot that have been extracted at the first extracting.
