Hi there, [.bringing this back to the list since it doesn't seem like
your message was purposefully aimed at just me]

ah, thanks. I think I was able to make out enough parts of the
portuguese to understand :)

hmm so according to this page, the values:
SMF.s0.g_bytes and SMF.s0.g_space should represent the cache usage /
total, have I read this out correctly?
If I calculate with what I have:
SMF.s0.g_bytes 256258048 . Bytes outstanding
SMF.s0.g_space 817483776 . Bytes available
it gives roughly 245Mb used over roughly 780Mb total for the cache.
but in /etc/default/varnish I have the following as an argument to the
daemon:
INSTANCE=$(uname -n)
DAEMON_OPTS="#[...irrelevant] \
-s file,/var/lib/varnish/$INSTANCE/varnish_storage.bin,1G"
# ls -l /var/lib/varnish/cache01/varnish_storage.bin
-rw------- 1 root root 1073741824 Jul 10 22:35
/var/lib/varnish/cache01/varnish_storage.bin
so I'm wondering whether the cache file is not used entirely or else the
values don't correspond to the cache file's usage and total size..
