From Machine Logs to Actionable Insights: LLMs for Failure Analysis – Paritosh Sinha at DLDC 2023

This talk emphasizes the crucial role of leveraging LLMs to extract actionable insights from machine logs, specifically for failure analysis

Paritosh Sinha’s enlightening talk at DLDC 2023 emphasized the crucial role of leveraging language models to extract actionable insights from machine logs, specifically for failure analysis. This article provides an overview of his talk and the insights shared.

The Need for Leveraging Language Models in Failure Analysis

Traditionally, product improvement has relied on user and engineer feedback, but dealing with vast volumes of unstructured failure logs presents a significant challenge. Paritosh presented a fresh approach that harnesses the power of language models to categorize failures into themes, offering a systematic way to identify product enhancements and determine the underlying causes of system failures.

A Four-Step Approach for Failure Analysis Using Language Models

Paritosh outlined a comprehensive four-step approach for grouping failures through language model embedding. This approach involves error message collection and cleaning, training the model based on product-specific keywords, embedding generation and transformation, and weighted clustering of error messages. Each step plays a crucial role in extracting meaningful insights from failure logs.

Comparison of FSC Pattern Empty Model and Sbert Model

During the talk, Paritosh discussed the comparison between a standard FSC pattern empty model and an Sbert model for model training and inference. The FSC pattern empty model demonstrated significantly higher efficiency, highlighting the importance of selecting the most suitable language model for the specific use case.

Custom Function for Handling Shorter Sentences

Paritosh introduced a custom function to handle shorter sentences, ensuring that similar sentences were appropriately represented with similar distances between them. This customization helps maintain the integrity and accuracy of the failure analysis process.

Assessing Relevance of Embeddings and Weighted Clustering

The talk highlighted the relevance of embeddings in failure analysis and the importance of weighted clustering for identifying common categories and themes within failure logs. This approach provides a more programmatic way to suggest product enhancements and determine the root causes of system failures.

Key Takeaways for Effective Failure Analysis

The key takeaway from Paritosh’s talk was the importance of selecting the most suitable language model for the specific use case. Considering the trade-off between performance and computation time is essential when implementing failure analysis techniques. The application of language models and clustering methodologies not only enhances product performance but also reduces computation time by efficiently grouping failures into common categories.

Paritosh Sinha’s talk at DLDC 2023 provided valuable insights into the application of language models for failure analysis. By leveraging language models and embedding techniques, organizations can gain actionable insights from machine logs, leading to improved product performance, enhanced user experiences, and a more efficient identification of system failures.
