Thank you for your replies Raymond and Nathan.
Can you possibly shed some light on the " /usr/sbin/invoke-rc.d"
part? Read on for more context...
I want to use logrotate to rotate the varnish log files. I found the
file (/home/username/varnish-1.1.1/debian/varnish.logrotate)
containing the following:
>>>
/var/log/varnish/varnish.log {
daily
rotate 7
compress
delaycompress
postrotate
/usr/sbin/invoke-rc.d varnishlog reload > /dev/null
endscript
}
>>>
However, we are using varnishncsa and not varnishlog. Running "ps aux
| grep varnish" yields:
>>
/opt/varnish/sbin/varnishd
/opt/varnish/bin/varnishncsa -a -c -w /var/log/varnish.log
>>
Is setting up logrotate for varnishncsa as simple as changing the
invoke-rc.d line of the logrotate file to be:
>>
/usr/sbin/invoke-rc.d varnishncsa reload > /dev/null
>>
If so, how to pass in the ncsa commandline parameters?
Thanks for any guidance.

Does anyone successfully have logrotate working with varnishncsa?
Thanks,

Below is the solution I came up with. The lastaction part may not be
necessary for anyone else, but on occasion it seemed to be necessary
for us, and rather than spending much time looking into the underlying
cause I'm okay with this solution.

/etc/logrotate.d/varnish
===========================
/var/log/varnish/varnish.log {
daily
rotate 52
compress
create
delaycompress
dateext
postrotate
/usr/sbin/invoke-rc.d varnishlog reload > /dev/null
DATE=$(date +%Y%m%d)
VDIR=/var/log/varnish
# varnishlog or varnishncsa(??) seems to produce a lot of entries
that are null,
# the grep -v in the middle just attempts to eliminate them
/usr/bin/ionice -c3 /usr/bin/varnishncsa -r
$VDIR/varnish.log-$DATE | grep -v '^- - -' | gzip >
$VDIR/varnish.log-$DATE.gz && rm $VDIR/varnish.log-
$DATE
endscript
lastaction
# Sometimes, for reasons that I can't explain, varnishlog stops
logging after
# rotation. The new log just sits there at 0 bytes and it takes
a reload to
# make it start logging again. It could be some complex timing
issue, but
# hopefully just adding one last restart of varnishlog will be
enough.
/usr/sbin/invoke-rc.d varnishlog force-reload > /dev/null
endscript
}
