NAME
traffic_logcat - Traffic Server log spooler
SYNOPSIS
traffic_logcat [-o output-file | -a] [-CEhSVw2] [input-file ...]
DESCRIPTION
To analyze a binary log file using standard tools, you must first convert it to ASCII. traffic_logcat does exactly that.
OPTIONS
- -o PATH, --output_file PATH
Specifies where the command output is directed.
- -a, --auto_filename
Automatically generates the output filename based on the input filename. If the input is from stdin, then this option is ignored. For example:
traffic_logcat -a squid-1.blog squid-2.blog squid-3.blog
generates:
squid-1.log squid-2.log squid-3.log
- -f, --follow
Follows the file, like tail(1) -f
- -C, --clf
Attempts to transform the input to Netscape Common format, if possible.
- -E, --elf
Attempts to transform the input to Netscape Extended format, if possible.
- -S, --squid
Attempts to transform the input to Squid format, if possible.
- -2, --elf2
Attempt to transform the input to Netscape Extended-2 format, if possible.
- -T, --debug_tags
- -w, --overwrite_output
- -h, --help
-
Print usage information and exit.
- -V, --version
-
Print version information and exit.
NOTE:
Use only one of the following options at any given time: -S, -C, -E, or -2.
If no input files are specified, then traffic_logcat reads from the standard input (stdin). If you do not specify an output file, then traffic_logcat writes to the standard output (stdout).
For example, to convert a binary log file to an ASCII file, you can use the traffic_logcat command with either of the following options below:
traffic_logcat binary_file > ascii_filetraffic_logcat -o ascii_file binary_file
The binary log file is not modified by this command.
