The main purpose of LoFiMo is, as the name states, to monitor log files. It does this in real time, i.e. shows the contents of log files as they are changing. The user can connect to LoFiMo with a Web browser or use the console for plain text output. When using a Web browser, the output can be formatted with cascading stylesheets, which the user can define. Thus, it is possible to highlight certain log entries with different colors and fonts. It is also possible to play sounds or execute commands (send an email, play sound with a custom player, etc.) when a log entry matches a filter. LoFiMo can parse Apache style log files and syslog style log files. Among others, there are filters that can parse iptables logs and merge multiple log lines of Postfix into a single one.
F.L.A.V.I.O. is a data grapher for netflow collectors. It gathers data from a netflow collector, loads it into a MySQL database and can generate daily, weekly, monthly, and yearly charts. It shows traffic split by ports, statistics on total utilization, and generates percentile 95 information suitable for billing in burstable services. It has been written in Perl using DBD, DBI, and GD modules, and can be easily extended to support new features or to present data in different formats.
