Logdissect

Supports extensive filtering by time ranges, hostnames, processes, protocols, and custom patterns using grep-like syntax, as detailed in the options list for precise log isolation.

Includes built-in parsers for common formats like syslog, web access logs, Cisco IOS logs, and tcpdump output, enabling out-of-the-box analysis for diverse log sources.

Uses file modification times to assign years to timestamps, allowing reliable parsing of logs spanning multiple years without manual year specification, as noted in the metadata section.

Exports results as standard log files, line-by-line JSON, or single-object JSON with pretty-print options, facilitating further processing or integration with other tools.
