NAME

       traffic_logstats - Traffic Server analyzer

SYNOPSIS

       traffic_logstats [options]

DESCRIPTION

       traffic_logstats  is  a log parsing utility, that is intended to produce metrics for total
       and per origin requests. Currently, this utility only supports parsing and processing  the
       Squid binary log format, or a custom format that is compatible with the initial log fields
       of the Squid format.

       Output can either be a human readable text file, or a JSON format.  Parsing  can  be  done
       incrementally,  and  traffic_logstats  supports  restarting  where  it left off previously
       (state is stored in an external file). This is useful when collecting metrics periodically
       into a stats processing system, and also supports the case where a log file is rotated.

       The  per-URL metrics (-u) requires that you specify a size of the LRU used for keeping the
       counters. This is to assure that traffic_logstats does not consume an exorbitant amount of
       memory.

OPTIONS

       -f FILE, --log_file FILE
              Specific logfile to parse

       -o LIST, --origin_list LIST
              Only show stats for listed Origins

       -O FILE, --origin_file FILE
              File listing Origins to show

       -M COUNT, --max_origins COUNT
              Max number of Origins to show

       -u COUNT, --urls COUNT
              Produce JSON stats for URLs, argument is LRU size

       -U COUNT, --show_urls COUNT
              Only show max this number of URLs

       -A, --as_object
              Produce URL stats as a JSON object instead of array

       -C, --concise
              Eliminate metrics that can be inferred from other values

       -i, --incremental
              Incremental log parsing

       -S FILE, --statetag FILE
              Name of the state file to use

       -t, --tail
              Parse the last <sec> seconds of log

       -s, --summary
              Only produce the summary

       -j, --json
              Produce JSON formatted output

       -c, --cgi
              Produce HTTP headers suitable as a CGI

       -m, --min_hits
              Minimum total hits for an Origin

       -a, --max_age
              Max age for log entries to be considered

       -l COUNT, --line_len COUNT
              Output line length

       -T TAGS, --debug_tags TAGS
              Colon-Separated Debug Tags

       -r, --report_per_user
              Report  stats  per  username  of the authenticated client caun instead of host, see
              squid log format

       -n, --no_format_check
              Don't validate the log format field names according to the squid log format.   This
              would  allow  squid  format  fields  to  be  replaced,  i.e.  the  username  of the
              authenticated client caun with a random header value by using cqh, or to remove the
              client's host IP address from the log for privacy reasons.

       -h, --help
              Print usage information and exit.

       -V, --version
              Print version information and exit.
