This publish is co-written by Fan Zhang, Sr Principal Engineer / Architect from Palo Alto Networks.

Palo Alto Networks’ Gadget Safety staff needed to detect early warning indicators of potential manufacturing points to offer extra time to SMEs to react to those rising issues. The first problem they confronted was that reactively processing over 200 million each day service and utility log entries resulted in delayed response occasions to those important points, leaving them in danger for potential service degradation.

To handle this problem, they partnered with the AWS Generative AI Innovation Middle (GenAIIC) to develop an automatic log classification pipeline powered by Amazon Bedrock. The answer achieved 95% precision in detecting manufacturing points whereas decreasing incident response occasions by 83%.

On this publish, we discover how you can construct a scalable and cost-effective log evaluation system utilizing Amazon Bedrock to rework reactive log monitoring into proactive subject detection. We talk about how Amazon Bedrock, by means of Anthropic’ s Claude Haiku mannequin, and Amazon Titan Textual content Embeddings work collectively to mechanically classify and analyze log information. We discover how this automated pipeline detects important points, study the answer structure, and share implementation insights which have delivered measurable operational enhancements.

Groups going through related log evaluation challenges can discover sensible insights on this implementation.

Resolution overview

Palo Alto Networks’ automated log classification system helps their Gadget Safety staff detect and reply to potential service failures forward of time. The answer processes over 200 million service and utility logs each day, mechanically figuring out important points earlier than they escalate into service outages that affect clients.

The system makes use of Amazon Bedrock with Anthropic’s Claude Haiku mannequin to grasp log patterns and classify severity ranges, and Amazon Titan Textual content Embeddings allows clever similarity matching. Amazon Aurora gives a caching layer that makes processing large log volumes possible in actual time. The answer integrates seamlessly with Palo Alto Networks’ current infrastructure, serving to the Gadget Safety staff concentrate on stopping outages as an alternative of managing complicated log evaluation processes.

Palo Alto Networks and the AWS GenAIIC collaborated to construct an answer with the next capabilities:

• Clever deduplication and caching – The system scales by intelligently figuring out duplicate log entries for a similar code occasion. Reasonably than utilizing a big language mannequin (LLM) to categorise each log individually, the system first identifies duplicates by means of actual matching, then makes use of overlap similarity, and eventually employs semantic similarity provided that no earlier match is discovered. This method cost-effectively reduces the 200 million each day logs by over 99%, to logs solely representing distinctive occasions. The caching layer allows real-time processing by decreasing the necessity for redundant LLM invocations.
• Context retrieval for distinctive logs – For distinctive logs, Anthropic’s Claude Haiku mannequin utilizing Amazon Bedrock classifies every log’s severity. The mannequin processes the incoming log together with related labeled historic examples. The examples are dynamically retrieved at inference time by means of vector similarity search. Over time, labeled examples are added to offer wealthy context to the LLM for classification. This context-aware method improves accuracy for Palo Alto Networks’ inner logs and programs and evolving log patterns that conventional rule-based programs battle to deal with.
• Classification with Amazon Bedrock – The answer gives structured predictions, together with severity classification (Precedence 1 (P1), Precedence 2 (P2), Precedence 3 (P3)) and detailed reasoning for every determination. This complete output helps Palo Alto Networks’ SMEs rapidly prioritize responses and take preventive motion earlier than potential outages happen.
• Integration with current pipelines for motion – Outcomes combine with their current FluentD and Kafka pipeline, with information flowing to Amazon Easy Storage Service (Amazon S3) and Amazon Redshift for additional evaluation and reporting.

The next diagram (Determine 1) illustrates how the three-stage pipeline processes Palo Alto Networks’ 200 million each day log quantity whereas balancing scale, accuracy, and cost-efficiency. The structure consists of the next key parts:

• Knowledge ingestion layer – FluentD and Kafka pipeline and incoming logs
• Processing pipeline – Consisting of the next phases:
  • Stage 1: Good caching and deduplication – Aurora for actual matching and Amazon Titan Textual content Embeddings for semantic matching
  • Stage 2: Context retrieval – Amazon Titan Textual content Embeddings to allow historic labeled examples, and vector similarity search
  • Stage 3: Classification – Anthropic’s Claude Haiku mannequin for severity classification (P1/P2/P3)
• Output layer – Aurora, Amazon S3, Amazon Redshift, and SME assessment interface

The processing workflow strikes by means of the next phases:

• Stage 1: Good caching and deduplication – Incoming logs from Palo Alto Networks’ FluentD and Kafka pipeline are instantly processed by means of an Aurora primarily based caching layer. The system first applies actual matching, then falls again to overlap similarity, and eventually makes use of semantic similarity by means of Amazon Titan Textual content Embeddings if no earlier match is discovered. Throughout testing, this method recognized that greater than 99% of logs corresponded to duplicate occasions, though they contained totally different time stamps, log ranges, and phrasing. The caching system lowered response occasions for cached outcomes and lowered pointless LLM processing.
• Stage 2: Context retrieval for distinctive logs – The remaining lower than 1% of really distinctive logs require classification. For these entries, the system makes use of Amazon Titan Textual content Embeddings to establish probably the most related historic examples from Palo Alto Networks’ labeled dataset. Reasonably than utilizing static examples, this dynamic retrieval makes positive every log receives contextually applicable steering for classification.
• Stage 3: Classification with Amazon Bedrock – Distinctive logs and their chosen examples are processed by Amazon Bedrock utilizing Anthropic’s Claude Haiku mannequin. The mannequin analyzes the log content material alongside related historic examples to provide severity classifications (P1, P2, P3) and detailed explanations. Outcomes are saved in Aurora and the cache and built-in into Palo Alto Networks’ current information pipeline for SME assessment and motion.

This structure allows cost-effective processing of large log volumes whereas sustaining 95% precision for important P1 severity detection. The system makes use of fastidiously crafted prompts that mix area experience with dynamically chosen examples:
