vvtr(1)

NAME

vvtr - MSB process

SYNOPSIS

/usr/vtr/bin/vvtr [ -B bytes ] [ -f log-level ]

[ -F log-file ] [ -l log-options ] [ -p ] [ -P priority ]

[ -s log-level ] [ -u num-units ] [ -v log-level ]

DESCRIPTION

The MSB process server is the main executable of the MSB platform software. Note, however, that under normal circumstances vvtr is not run on its own but is launched by the MSB parent daemon, vtrd.

vvtr has the following options:

-B bytes

Set the default stream I/O buffer size to bytes.

-f log-level

Set the maximum log message priority for the log file to Info+log-level. The default is 0, meaning all log messages up to and including Info priority are written to the log file.

-F log-file

Write the log file to log-file. The default is /var/adm/vtr/logs/vtrlog.

-l log-options

Omit specified log message fields from log messages.

log-options is one or more of the following:

l

Omit priority level indicator.

p

Omit process id (pid).

t

Omit timestamp.

t

Omit date.

Level, process id, and timestamp are always omitted from log messages in SYSLOG.

-p

Do not use real-time scheduling priorities.

-P priority

Set base scheduling priority to priority. The default is system-dependent.

-s log-level

Set the maximum log message priority for SYSLOG to Info+log-level. The default is 0, meaning all log messages up to and including Info priority are written to SYSLOG.

-t

Truncate the log file when it is opened. If this option is not specified, the new log messages are appended to the existing log file.

-u num-units

Set the maximum number of concurrent units to num-units. This reserves statically-allocated resources to support the specified number of units. The default is 32.

-v log-level

Set the maximum log message priority for stdout to Info+log-level. The default is 0, meaning all log messages up to and including Info priority are written to stdout.

LOGGING

MSB logs to several destinations. The -f, -s, and -v options are used to adjust the lower bound on the priority of messages logged to each of the log file, system log, and stdout.

The -F option can be used to change the name of the log file (the default is /usr/vtr/logs/vtrlog). If the -t option is used, the log file is truncated each time it is opened; otherwise, the new log messages are appended to the existing log file.

If MSB is sent a SIGHUP signal, it responds by reopening the log file. SIGHUP can be used to rotate log files while MSB remains running.
