Profiles and parsing.
A profile turns physical lines into logical records and named fields. It may provide typed timestamps, multiline grouping, default wrapping, source metadata, and columns that expression filters and Query Tabs can address by name.
Profiles available from the F8 picker.
File extensions and source types can choose an initial profile, but the picker remains available for manual overrides.
Teach LogAce a format without preprocessing it.
Ad Hoc · per source
Choose delimiter, regex, or fixed-width parsing. Name fields, trim values, mark expand/wrap/continuation targets, add a record-start regex, and declare typed datetime formats.
Custom · current CLI invocation
--delimiter or --regex creates a Custom profile for the run. --headers supplies explicit field names.
Saved user profiles
F5 saves an Ad Hoc definition or duplicates a selected saved profile. F4 edits the selected [user] entry; Delete removes it from the global profile catalog.
Profile-specific presentation
Ctrl+L keeps visibility, widths, wrapping, maximum cell height, and virtual columns per profile without changing the parser definition itself.
Derive useful fields from parsed values.
Virtual columns can be declared inside Ad Hoc parsing or added later through Ctrl+L. They read one or more physical source fields without rewriting the log.
