Meeting Details...

     The meetings are always free, but dinner is not (unless you are our
     guest speaker, in which case we also treat you to dinner).  For
     Henry's Hunan Restaurant, if folks are agreeable, we'll share and
     dine "family" style, and split up the costs, and typical cost per
     person including tax and tip (but not including beverages beyond
     complementary tea) would be in the $13.00 to $17.50 range, and
     commonly around $15.00 to $16.50.  Cash may be preferred to ease
     splitting up the check.  One can also specifically order the
     dish(es) one needs/prefers (e.g. for dietary considerations) - and
     we also commonly order some dish(es) that may meet various dietary
     considerations) (e.g. vegetarian, non-pork, ...).  Please arrive by
     7:00 P.M., we expect to order entrees at that time, and may order
     appetizer(s) and/or soup(s) anytime after 6:30 P.M.


For our 2016-10-18 BALUG meeting:

Fred Moyer - Better service monitoring through histograms

Fred Moyer will introduce us to statistical based service monitoring.
If you've used something like Nagios[1], Graphite[2], or Zabbix[3] to
monitor your systems, you're probably familiar with threshold based
alerting. Specifically, that it often results in you waking up in the
middle of the night for false positives. This talk will show you how to
implement quantile based service monitoring with histograms, so that
you can understand how your service is actually doing, rather than just
guessing based on metric averages.

We typically have various giveaway items at BALUG meetings.  We'll
likely have at least the below plus additional items.

Books and other titles!
have a look/read here:

CDs/DVDs/ISOs, etc. - have a peek here:
We may also be able to "burn" images per request or copy to USB flash,
etc.  Donations of blank or +-RW media, USB flash, or funding thereof,
also appreciated.  See the above URL for details (and the inventory
(qty.) of what we specifically have "burned" and available on-hand does
also frequently change).


Upcoming BALUG list changes?!

Yes, for the past many years, much of BALUG, including our lists, has
been and is still presently hosted on DreamHost.com.  We will be
changing that in the not-too-horribly-distant-future.  (primary
volunteer on this has been buried under some other stuff to attend to,
so taking a bit longer.) We'll update on status when that's about to
change and when it does change.  We'll provide more details as we
approach and go through that transition, and we'll make it as painless
as feasible.
