tolog is a simple tool to make software that logs to standard output play nice with logrotate.
Pipe the output of your software to tolog, keep a PID file. In practice you will probably do this in an init script.
myprogram | tolog /var/log/myprogram.log & echo $! > /var/run/myprogram.tolog.pid
Tell logrotate to send USR1 to tolog to reopen the logfile after rotating.
/var/log/myprogram.log {
missingok
compress
postrotate
test -r /var/run/myprogram.tolog.pid && kill -USR1 `cat /var/run/myprogram.tolog.pid`
endscript
}
