Inspect a representative slice of an oversized log without asking an editor to swallow the whole file. Search, filter, pin the evidence, and leave a handoff.
Analyze a sample to create a compact review.
Log Scope splits pasted text on newline and labels each line by case-insensitive substring: ERROR or FATAL first, then WARN, otherwise INFO. In the illustrated six-line fixture, two lines match error, one matches warning and three fall through to info, including a blank line. Three bars use one hundred pixels per line to show two hundred, one hundred and three hundred pixels. This is string matching, not a log schema parser, root-cause diagnosis or a live service feed. Pinning stores original one-based line numbers rather than copies of line text. In the fixture, lines two and four are pinned. If the input is replaced with one line, those two stored numbers remain, while zero pinned texts survive. Bars compare two stored pin numbers with zero surviving texts at one hundred fifty pixels per count. The pinned count still shows two, the handoff preview asks for evidence, and Markdown emits blank text for both missing numbers. These are source rules, not preserved immutable evidence. All, Error, Warn and Info are four view filters, combined with case-insensitive substring search. Bars compare four filters with two stored properties at one hundred pixels per count. Source text and pin numbers persist; filter and search return to defaults on reload. Both Markdown buttons export the same current handoff, while Copy writes filter, query and pins as JSON. Reset reloads the fixed sample. No external logs, backend model, service health or incident conclusion is verified.
