Monitoring cache file usage with varnish 3

Hi there,

I've recently upgraded a cluster's caching nodes to varnish 3, and saw
that our graphs for the cache file usage were now giving no info anymore.

from what I could see, that's because the value "sm_balloc" is just not
there anymore in the output of varnishstat -1. unfortunately, I couldn't
find a replacement for it for disk-based cache files.

Is there a way to monitor usage and free space of the cache file with
varnish 3?

Hello,

bumping this to see if anyone can help.

any idea what I can use instead of sm_balloc for monitoring cache file?

if my message is confusing, I can point to more detailed information.

Hi Gabriel,

You should be able to use SMF.s0.g_bytes (bytes allocated) and
SMF.s0.g_space (bytes free). To total amount of possible memory would be
the sum of both.

Mattias
