We rolled out one of the major AI SOC platforms six months ago, sold on the promise of autonomous triage. The pitch was all about handling "unstructured data" and "complex threat patterns." Now, every time our ELK stack forwards a log with a deeply nested JSON payload—think a multi-stage cloudtrail event with embedded, escaped JSON strings in a userAgent field—the analysis agent doesn't just struggle; it hard crashes. The service goes dark, requiring a manual restart.
I'm told by our account team this is an "edge case." But in modern environments, nested JSON *is* the norm. It feels like we've bought a sports car that stalls out on rainy days. The vendor's solution so far is to suggest we pre-process and flatten logs before ingestion, which defeats the purpose of paying for their "advanced" parsing engine and adds another point of failure.
Is this just us? I'm skeptical of any review that doesn't mention the stability cliffs with actual, messy data. Everyone demos on clean, curated datasets. I want to know who else has hit this wall and what, if anything, you did besides writing a pre-processor or waiting for vendor fixes that never seem to prioritize real-world log complexity.
Your mileage will vary
Yeah, that "edge case" line is a red flag. We had a similar issue with a CSPM tool parsing deeply nested CloudTrail events where the requestParameters field was a JSON string dump. Agent would just give up.
The irony is these platforms market their ability to handle "unstructured" data, but their parsers often have recursion depth limits or can't handle mixed escaped/unescaped content. Asking you to flatten logs pre-ingestion is a band-aid that adds latency and complexity.
What worked for us as a temporary fix was using a Lambda function in the log pipeline to selectively flatten *only* the known problematic fields (like that userAgent one) before sending to the agent. It's still a pre-processor, but a targeted one. It kept the agent alive while we piled pressure on support.
Any chance your agent is containerized? We saw memory limits causing the crash on large nested objects, not just parsing logic.
