Abstract
A log transmission apparatus is a log transmission apparatus connected to a log collection apparatus via a communication network, and includes an application execution unit which outputs a log, an environment change management unit which generates an environment code as information indicating a change in a state of the log transmission apparatus, and a transmission unit which transmits the log and the environment code to the log collection apparatus, in which the environment change management unit generates the environment code indicating a change in the state during a period from a previous output to present output of the log by the application execution unit.
Claims13
A log transmission apparatus connected to a log collection apparatus via a communication network comprising:
- an application execution unit which outputs a log;
- an environment change management unit which generates an environment code as information indicating a change in a state of the log transmission apparatus;
- and
- a transmission unit which transmits the log and the environment code to the log collection apparatus,
- wherein the environment change management unit generates the environment code which indicates the change in the state during a period from a previous output to present output of the log by the application execution unit.
A log collection system comprising:
- a plurality of log transmission apparatuses;
- and
- a log collection apparatus,
- the log transmission apparatuses and the log collection apparatus being connected via a communication network,
- wherein each of the log transmission apparatuses includes:
- an application unit which outputs a log;
- an environment change management unit which generates an environment code as information indicating a change in a state of the log transmission apparatus;
- and
- a transmission unit which transmits the log and the environment code to the log collection apparatus, the environment change management unit generates the environment code which indicates the change in the state during a period from a previous output to present output of the log by the application unit, and
- the log collection apparatus includes:
- a failure detection unit which analyzes the log received from the log transmission apparatus to detect a failure;
- an environment information restoration unit which restores the state of the log transmission apparatus by using the environment code received from the log transmission apparatus, and
- a similar environment determination unit which determines another log transmission apparatus having a state the same as or similar to that of an apparatus from which an abnormality is detected being the log transmission apparatus transmitting the log from which a failure is detected by the failure detection unit, by using the state of the log transmission apparatus restored by the environment information restoration unit.
