14.3.4 Gathering Statistics from syslog
The logfiles that syslog creates provide a wealthof information that can be used to
examine and tune the performance of sendmail. To illustrate, we will present a simple
shell script for printing daily total message volume.
In the following discussion, we will assume that sendmail logging is enabled (the
LogLevel option, ?§24.9.61 on page 1040, is nonzero) and that all syslog(8) messages
for the facility mail at level LOG_INFO are being placed into the file /var/log/syslog.
