Abstract
Normal and abnormal states are calculated from log data with respect to each of a plurality of processings in which shared modules exist. A timing of a change of the states is calculated. A time interval, in which the normal and abnormal states are not mixed, is separated with respect to each of the plurality of processings, based on the calculated timing. In the time interval, an abnormal module is detected, based on relationship information between the plurality of processings and the modules.
Claims8
An analysis method comprising:
- calculating normal and abnormal states from log data with respect to each of a plurality of processings in which shared modules exist;
- calculating a timing of a change of the states;
- separating a time interval, in which the normal and abnormal states are not mixed, with respect to each of the plurality of processings, based on the calculated timing;
- and
- detecting an abnormal module in the time interval, based on relationship information between the plurality of processings and the modules.
An analysis apparatus equipped with a computer, wherein the computer is configured to:
- calculate normal and abnormal states from log data with respect to each of a plurality of processings in which shared modules exist;
- calculate a timing of a change of the states;
- separate a time interval, in which the normal and abnormal states are not mixed, with respect to each of the plurality of processings, based on the calculated timing;
- and
- detect an abnormal module in the time interval, based on relationship information between the plurality of processings and the modules.
A non-transitory computer-readable recording medium storing an analysis program to cause a computer to execute:
- calculating normal and abnormal states from log data with respect to each of a plurality of processings in which shared modules exist;
- calculating a timing of a change of the states;
- separating a time interval, in which the normal and abnormal states are not mixed, with respect to each of the plurality of processings, based on the calculated timing;
- and
- detecting an abnormal module in the time interval, based on relationship information between the plurality of processings and the modules.
