A Lightweight Algorithm for Message Type Extraction in Event Logs
نویسندگان
چکیده
Message type or message cluster extraction is an important task in automatic application log analysis. When the message types that exist in a log file are defined, they form the basis for carrying out other automatic application log analysis tasks. In this paper we introduce a novel algorithm for carrying out this task. IPLoM, which stands for Iterative Partitioning Log Mining, works through a 4-step process. The first 3 steps hierarchically partition the event log into groups of event log messages or event clusters. In its 4th and final stage IPLoM produces a message type description or line format for each of the message clusters. IPLoM is able to find clusters in data irrespective of the frequency of its instances in the data, it scales gracefully in face of long message type patterns and produces message type descriptions at a level of abstraction which is preferred by a human observer. Evaluations show that IPLoM outperforms similar algorithms statistically significantly.

Message Type Extraction Based Alert Detection in System Logs
The task of alert detection in event logs, i.e. determining which events in the event log require action from an administrator, is very important in preventing or recovering from downtime events. The ability to do this automatically and accurately provides significant savings in time and cost of downtime events. In this work we combine message type extraction based alert detection with the entr...

In this paper we present the results on extracting message types from the BlueGene/L supercomputer logs using the IPLoM (Iterative Partitioning Log Mining) algorithm. Previous work using IPLoM indicates that IPLoM shows promise as message type extraction algorithm. We compared the results of IPLoM against manually produced message types produced on the BlueGene/L data. To provide a baseline of ...

In the existing Fault-Tolerant Software Distributed Shared Memory (FT-SDSM) with the message logging, the logs are used only to recover the failed nodes. In our previous work, we have implemented a lightweight logging protocol, called remote logging, on the SDSM for fault tolerance, which incurs low logging overhead with a fast network and a remote memory for back-up data. In this paper, we pro...
