ModLogAn is a modular logfile analyzer that combines speed with flexibility. It parses the logfiles generated by several server-types (HTTP, FTP, mail, streaming, etc.) and other logfile sources (flow-tools, ipchains, PABXs): currently 24 parsers. It features incremental logfile processing and internal resolving, and is able the split (mass-hosting) and combine logfiles (clusters) internally. The output can be based on the internal template engine to generate your own look & feel.
