FAQ
The Dev app runs the 10x Engine locally to preview how edge and cloud apps will process your log data without requiring backend connections or infrastructure changes.
Overview
What is Dev and what can I use it for
Dev runs the 10x Engine locally to preview how edge and cloud apps will process your log data. One use is estimating optimization savings — point it at sample log files and Dev will:
- Calculate reduction ratios
- Show which log patterns optimize best
- Provide detailed metrics on potential cost reductions
Runs entirely on your local machine with no data leaving your environment. Useful for evaluation, POC preparation, and ongoing configuration testing.
How do I install Dev
See Install for platform-specific packages and instructions.
Is Dev free
Yes. Dev requires no account and no signup. An API key validates your license at startup to unlock pre-compiled symbol libraries -- then runs entirely offline. No usage limits.
Capabilities
What log formats does Dev support
Dev analyzes any text-based log format:
- JSON, key-value pairs, syslog
- Common log formats (Apache, nginx)
- Application logs and unstructured text
The tool automatically detects log structure and applies optimization analysis.
Analyze single files, directories, or pipe logs via stdin for forwarder integration. The same formats supported in production work identically in Dev.
How accurate are the savings estimates
Dev uses the same optimization engine as production Log10x. Reduction ratios and pattern analysis closely match what you'll see in production.
The key to accuracy is providing representative log samples -- include logs from different time periods, applications, and load conditions.
Dev processes your actual data, not benchmarks. Results reflect your specific log patterns. For POCs, analyze logs across your major sources for representative numbers.
Does Dev store or cache any log data
Dev writes analysis results to your specified output directory. You control where files are written and can delete them after analysis.
No data is sent externally or cached elsewhere. Your original log files are read but never modified.
Security & Workflow
How does Dev use the API key
Dev validates your license once at startup to unlock pre-compiled symbol libraries -- then runs entirely offline. No log data is ever transmitted.
What are symbol libraries? Pre-compiled log pattern definitions (hashed templates) derived from your source code. They contain no source code, no log data, and no telemetry -- only structural metadata for pattern matching.
What if the network is unavailable at startup? Dev will prompt for an offline license file. No outbound network calls are made after initial validation.
How do I move from Dev testing to production
The typical journey after Dev:
- Deploy Cloud Reporter to analyze costs in your existing platform (Splunk, Datadog, etc.)
- Deploy Edge Regulator and/or Edge Optimizer alongside your forwarder to optimize at source
- Optionally add Storage Streamer to archive to S3 and query on-demand
Each app deploys independently. See the App Guide for details.
