Log Summary Analyzer

The 30-second briefing on any log. Log Summary Analyzer turns a paste into headline numbers — totals, error and warning counts, unique IPs, status codes, time span and the loudest message — without configuration.

It is the fastest way to understand "what happened in this window" before digging into a specialized tool.

• Totals — lines, unique lines, span.
• Severity counts — error, warning, info.
• Uniques — IPs, status codes.
• HTTP breakdown — 4xx/5xx attention.
• Top message — loudest repeat.

1. Paste the log.
2. Analyze. The summary renders instantly.
3. Skim the headline numbers.
4. Drill down into a specialized tool next.

Example 1 — On-call triage. Pasted the last 500 lines; errors 3, warnings 12, a 5xx burst — straight to the status analyzer.

Example 2 — Health snapshot. Weekly cron dumps a window; the summary proves the ratio is stable.

Example 3 — Handoff. Attach the summary with the log so the next person starts informed.

• Zero config — paste and read.
• Fast triage — headline numbers.
• Broad parsing — many log formats.
• Private — fully in-browser.
