Day-to-Day we use computer for everything. Main thing we depend on computers for computing. For this purpose we build a large architecture of computers to do work for us. This architecture is maintain by the Qualified Persons ie System Administrator. Every architecture is will generate information about the working of it. So this information is termed as Events ie activities done in architecture.Based on this events System Administrator has to take spot decision for the next action.

Existing System:

For every Architecture we get thousands of events are generated.For clustering this events we have SLCT(Simple Log File Clustering Tool) and Loghound two algorithms,which are designed for automatically clustering log files and discovering event formats.These both algorithms lines in the message in event do not match any frequent patterns discovered are classified as outliers.

Proposed System:

The Proposed algorithm is IPLOM(Iterative Partitioning Log Mining) a novel algorithm for the mining of event type patterns from event logs.IPLOM not only finds frequent textual patterns,it also aims to find all possible patterns.IPLOM works through  3 step partitioning process which divide events into respective clusters.In fourth stage it produces the cluster description for each leaf partition of the events.


1.File_Prune Function

2.Partition by Event Size

3.Partition by Token Position

4.Partition by Search For Bijection

5.Discover Message Type Descriptions From Each Partition
