A combination of ACL, eCAP and caching is my goal. At the moment I'm
trying to make sense out of the statistics so I have metrics to guide
me. So now it's just a matter of comparing the various possible

Is there a tool or option to log statistics in machine readable format?
SNMP doesn't expose as much as I'd like and cachemgr output needs to be
gawked down to something like a csv file but still account for kids?

Also, is ssl_crtd disk DB ok to share among workers or do they each need
their own? I just realized I forgot to give the workers their own DB but
it seems to be working. Although not under load.

I really appreciate the help.
