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

Palo Alto Networks’ System Safety staff wished to detect early warning indicators of potential manufacturing points to supply 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 software log entries resulted in delayed response occasions to those vital points, leaving them in danger for potential service degradation.

To deal with 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 lowering incident response occasions by 83%.

On this publish, we discover the right way to construct a scalable and cost-effective log evaluation system utilizing Amazon Bedrock to remodel reactive log monitoring into proactive subject detection. We focus on how Amazon Bedrock, via Anthropic’ s Claude Haiku mannequin, and Amazon Titan Textual content Embeddings work collectively to robotically classify and analyze log information. We discover how this automated pipeline detects vital points, look at the answer structure, and share implementation insights which have delivered measurable operational enhancements.

Answer overview

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

The system makes use of Amazon Bedrock with Anthropic’s Claude Haiku mannequin to know log patterns and classify severity ranges, and Amazon Titan Textual content Embeddings permits 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’ present infrastructure, serving to the System Safety staff give attention to stopping outages as a substitute 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. Relatively than utilizing a big language mannequin (LLM) to categorise each log individually, the system first identifies duplicates via precise matching, then makes use of overlap similarity, and at last 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 permits real-time processing by lowering 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 via vector similarity search. Over time, labeled examples are added to supply wealthy context to the LLM for classification. This context-aware method improves accuracy for Palo Alto Networks’ inner logs and methods and evolving log patterns that conventional rule-based methods wrestle 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 choice. This complete output helps Palo Alto Networks’ SMEs shortly prioritize responses and take preventive motion earlier than potential outages happen.
• Integration with present pipelines for motion – Outcomes combine with their present 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 levels:
  • Stage 1: Good caching and deduplication – Aurora for precise 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 via the next levels:

• Stage 1: Good caching and deduplication – Incoming logs from Palo Alto Networks’ FluentD and Kafka pipeline are instantly processed via an Aurora primarily based caching layer. The system first applies precise matching, then falls again to overlap similarity, and at last makes use of semantic similarity via 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 completely different time stamps, log ranges, and phrasing. The caching system decreased response occasions for cached outcomes and decreased 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 determine probably the most related historic examples from Palo Alto Networks’ labeled dataset. Relatively than utilizing static examples, this dynamic retrieval makes certain every log receives contextually applicable steerage 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 supply severity classifications (P1, P2, P3) and detailed explanations. Outcomes are saved in Aurora and the cache and built-in into Palo Alto Networks’ present information pipeline for SME assessment and motion.

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