timefind v1.0.3 released with recursion support

timefind v1.0.3 has been released (available at

indexer and timefind will handle the indexing and selection of multiple network data types given some time range.

Major changes in 1.0.3 include:

  • new file processors for .csv, .fsdb, syslog, and BGP/MRT files
  • timefind and indexer now support traversing the file hierarchy with recursive processing
  • index entries now have a “last modified” column timestamp: existing entries will be reindexed if that file was modified after index creation.

Many thanks to Paul Ferrell (LANL) and Paige Hanson (LANL) for their contributions in timefind extensions.

timefind v1.0.2.2 released

timefind v1.0.2.2 has been released (available at

Scientists at Los Alamos National Laboratory and at USC/ISI have developed two tools to handle indexing and selection of multiple network data types: indexer and timefind.

Most of us have processed large amounts of timestamped data. Given .pcap spanning 2010-2015, we might want to downselect on a time range, e.g., 2015-Jan-01 to 2015-Feb-01. An existing way to downselect would be to build fragile regexes and walk the directory tree for each search: inefficient and inevitably re-written.

indexer will walk through all your data and index the timestamps of the earliest and latest records.

timefind will then use the indexes and retrieve the filenames that overlap with the given time range input. To downselect 2015-Jan-01 to 2015-Feb-01 on “dns” data, use:

timefind --begin="2015-01-01" --end="2015-02-01" dns

It’s that simple and consistent.
