About This Tool

The System Tools Viewer parses and normalizes messages from logs and alerts, producing structured records that can be analyzed for debugging and triage. Conceptually it treats each input line as a potential event, extracting timestamp, severity, service, and message text, then applies filters and mappings to unify formats. Beneficiaries include DevOps, SREs, and software teams who require fast correlation across services and time windows. Unique value lies in offline, deterministic parsing with configurable mappings, allowing audit-ready exports and consistent time handling across regions. Core features include input parsers for text and JSONL, field mapping, time normalization, keyword filtering, and exportable outputs (JSON/CSV). Advanced capabilities add regex-based pattern matching, cross-message linking, and hash-based audits. Typical use cases are root-cause analysis during incidents, validation of log pipelines, and preparing data for dashboards. The tool supports local processing to preserve privacy and can integrate with existing workflows via standard formats. Outputs enable downstream automation and reporting, while the normalization guarantees comparability across environments.

How to Use

  1. Provide inputs: data, format, time_window, severity, and optional services.
  2. Configure filters and mapping rules.
  3. Run analysis to produce records and summary.
  4. Review outputs and identify critical messages and trends.
  5. Export results as JSON or CSV for downstream workflows.

Frequently Asked Questions

Find Quick Answers

What data formats are supported?
The tool accepts plain text logs and JSON Lines (JSONL); it can parse common schemas by field names and mappings. It can be extended with configuration to handle additional structures.
Is processing local or cloud-based?
Processing is local by default and does not transmit inputs unless the user explicitly exports data. This preserves privacy and enables offline workflows.
What outputs are available?
Outputs include structured records, a summary of counts by severity and service, and optional export formats such as JSON and CSV; outputs can feed dashboards and CI pipelines.
How is time normalization handled?
Timestamps are parsed into RFC3339 UTC. Time window filtering is applied accordingly; when zones are ambiguous, UTC is assumed and converted to the standard format.
