chipmunk

Chipmunk is a native desktop log analysis tool built in Rust that handles arbitrarily large log files (tested to 10+ GB) without performance degradation. It supports real-time log collection via TCP, UDP, Serial, and command output, with specialized parsers for automotive formats (DLT, SomeIp) and built-in search, filtering, and metrics visualization.

What chipmunk is

A Rust-based desktop application providing memory-efficient log file ingestion with no-copy streaming architecture, supporting multiple input sources (network protocols, serial, subprocess), pluggable format parsers (DLT with embedded attachment inspection, SomeIp extraction from pcap), and dynamic real-time filtering with regex-based metric extraction and charting.

Quickstart

Get the chipmunk source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/esrlabs/chipmunk.git2cd chipmunk3# follow the project's README for install & configuration

Best use cases

Automotive Trace Analysis

Primary use case; handles DLT (Diagnostic Log and Trace) format natively with full attachment inspection, SomeIp packet extraction, and pcap/pcapng integration. Supports both offline trace files and live network collection.

Large-Scale Log File Inspection

Designed to handle multi-gigabyte log files with constant-time random access. Efficient for debugging production systems where log volumes exceed typical grep/tail workflow capacity.

Live Log Stream Monitoring and Analysis

Collects logs from multiple simultaneous sources (TCP, UDP, Serial, command output), applies real-time filters, and updates metrics/charts dynamically as new data arrives. Useful for embedded systems and networked devices.

Implementation considerations

Desktop-only deployment; ensure end-user desktop environment (Linux, Windows, or macOS) and Rust toolchain availability if building from source.
Memory consumption scales with file size and active filters; verify system RAM for gigabyte-scale logs (exact thresholds not documented).
Network input sources (TCP, UDP, Serial) require firewall and port configuration; serial support requires physical port access on target machine.
DLT and SomeIp format support out-of-the-box; custom format parsers require Rust development and plugin architecture familiarity.
Real-time metric/chart generation uses regex; complex regex patterns may degrade responsiveness on high-volume streams (performance tuning not detailed in excerpt).

When to avoid it — and what to weigh

Server-side or Headless Deployment Required — Chipmunk is a native desktop application only. No server, CLI tool, or API backend provided. Cannot be deployed in containerized, cloud, or headless environments without significant custom development.
Cross-Platform Deployment at Scale — Desktop application limits scalability and centralized log aggregation scenarios. Not suitable for multi-tenant or enterprise-wide log ingestion pipelines (consider Logstash, ELK, or Splunk alternatives).
Non-Automotive or Generic Logging — While general log search/filter works, specialized format support is automotive-focused. For generic syslog, JSON, or application logs without DLT/SomeIp parsing, simpler tools may suffice.
Zero User Interface Requirements — Requires desktop UI interaction. No programmatic API, scripting interface, or batch-mode processing exposed. Integration into fully automated workflows is not practical.

Security considerations

Desktop application; standard Rust memory safety protects against buffer overflows. Network input sources (TCP, UDP) should be firewall-restricted to trusted networks. No documented security audit, vulnerability disclosure policy, or threat model. Validate network protocol parsing for untrusted input. Serial port access requires OS-level permissions. Media file (image, video, audio) inline viewing may pose XSS or format-parsing risks; sandbox status Unknown.

Alternatives to consider

ELK Stack (Elasticsearch, Logstash, Kibana)

Server-based, scalable, multi-tenant log aggregation and visualization. Suitable for enterprise log pipelines but requires infrastructure and is not a single desktop tool.

Splunk

Commercial, enterprise log management platform with advanced indexing, alerting, and analytics. More feature-rich but proprietary and significantly higher cost than open-source desktop tools.

Open-source, centralized log management server. Self-hosted or cloud-based; multi-user and API-driven. Better for distributed systems than single-user desktop analysis.

chipmunk FAQ

Can Chipmunk be deployed on a remote server or cloud instance?

No. Chipmunk is a native desktop application only. It requires a local display and windowed environment. Server-side deployment, headless operation, or containerized deployment are not supported.

What file size limits exist?

Documentation states no fixed limits—only disk space. Tested with multi-gigabyte files (1–10 GB+). Exact memory and performance thresholds are Unknown; testing with your typical file sizes is recommended.

Can I automate log parsing or export results programmatically?

Unknown. No API, CLI tool, or scripting interface is described. Automation likely requires manual UI interaction or custom Rust development. Not practical for batch workflows.

Does Chipmunk support formats other than DLT and SomeIp?

Yes, it includes generic log search and filtering. But specialized automotive format support (DLT, SomeIp, pcap) is the primary feature set. Custom format support requires plugin development or source modification.
