GoAccess is a real-time Web log analyzer and interactive viewer for almost every Web server. It runs in a terminal and provides fast and valuable HTTP statistics for system administrators that require log monitoring and visual reports on the fly. GoAccess can monitor unique visitors, browsers, spiders, OS, hosts and IP geolocation, keyphrases, referring sites, status codes, etc. It has support for IPv6 and it parses nearly any Web log format.
pmacct is a small set of passive network monitoring tools to account, filter, classify, aggregate, and export IPv4 and IPv6 traffic. A pluggable and flexible architecture allows storing collected network data in memory tables, RDBMSs (MySQL, SQLite, PostgreSQL, BDB), and flat files, and also export via IPFIX, NetFlow, or sFlow protocols to remote collectors. pmacct features fully customizable historical data breakdown, sampling, BGP correlation, tagging, and triggers. Libpcap, ULOG, sFlow v2/v4/v5, NetFlow v1/v5/v7/v8/v9, and IPFIX are supported data capturing methods.
For a system administrator it is a bothersome job to sort out the interesting (and sometimes alarming) log entries from the pile of standard entries. Tidy distinguishes different services (telnet, finger, etc.) and removes standard entries. Furthermore tidy tries to extract a remote host from the messages. These remote hosts are added to a statistics database. The number of contacts of each service is saved together with the time/date stamp of the last contact. The statistics can be printed out as simple ASCII or HTML.
RadiusReport can analyse the logfiles produced by all the major Radius Servers including Livingston Radius V2.0+, V1.16, Merit Radius, Ascend Radius, Dale Reed's RadiusNT, Radiator Perl Radius Server, but excluding Microsoft Radius. It will allow you to produce many, varied, types of reports from one or multiple radius log files.
