8.11. The tungsten_merge_logs Script

The tungsten_merge_logs command is designed to aid troubleshooting by consolidating the various log files into one place ordered by time.

tungsten_merge_logs [ --after {TIMESTAMP} ] [ --before {TIMESTAMP} ] [ --debug, --d ] [ --extension, --X ] [ --help, -h ] [ --log-limit, --L ] [ --quiet, --q ] [ --replicator, --R ] [ --stdout, --O ] [ --verbose, -v ]


Table 8.10. tungsten_merge_logs Command-line Options

--after {TIMESTAMP}Discard all lines prior to {TIMESTAMP}
--before {TIMESTAMP}Discard all lines after {TIMESTAMP}
--debug, --d
--extension, --XSpecify the file extension (default: log) Do NOT include the period
--help, -hShow help text
--log-limit, --LSpecify the quantity of log files to gather (default: unlimited). When the wrapper rotates log files, it appends a period and an integer to the end of the log file name, when .1 is the newest and .2 is older and .3 older than that, etc. This parameter will gather the base log file plus limit minus one rotated files.
--quiet, --q
--replicator, --RInclude the replicator log files
--stdout, --OSend merged logs to STDOUT instead of a file
--verbose, -vShow verbose output

With no options specified, the tungsten_merge_logs script will gather all log files in the current directory and below.

For example:

shell> cd    
shell> tpm diag --all    
shell> tar xvzf ungsten-diag-2021-11-15-16-37-33.tgz    
shell> cd tungsten-diag-2021-11-15-16-37-33    
shell> tungsten_merge_logs

Would result in something like the following:

New merged log file ./merged.log created!

All logs files are gathered by default.

Using multiple options will aggregate the logs from the specified components.

Use of the --log-limit option works as follows:

  • a loglimit of 1 means gather the base file only, i.e. trepsvc.log

  • a loglimit of 2 means gather the base file and the first backup file, i.e. trepsvc.log and trepsvc.log.1

  • a loglimit of 3 means gather the base file and the first two backup files, i.e. trepsvc.log, trepsvc.log.1 and trepsvc.log.2

The {TIMESTAMP} must be specified as a single argument wrapped in quotes, in the format of 'yyyy/mm/dd hh:mm:ss', including a single space between the date and time. Hours are in 24-hour time, and all values should be left-padded with zeros. For example:

shell> tungsten_merge_logs --before '2021/09/27 21:58:02'
