[google-appengine] Re: Min idle instances setting not working at all?

2011-09-13 Thread Pol
Hi Jon,

I don't know where you got that information, the admin logs clearly
reflect our actions and the feedback at the time in the Dashboard:

Originally set to 5:
2011-08-31 23:15:59 ad...@everpix.net   Changed Performance Settings
max_idle_clones=5, min_pending_latency=0.10

Then looking at estimated new-pricing bills, I figured that's looks
very expensive, let's reduce this as much as possible for now:
2011-09-01 00:08:03 ad...@everpix.net   Changed Performance Settings
max_idle_clones=3, min_pending_latency=0.10
2011-09-01 18:44:01 ad...@everpix.net   Changed Performance Settings
max_idle_clones=2, min_pending_latency=0.10
2011-09-03 12:07:44 ad...@everpix.net   Changed Performance Settings
max_idle_clones=1, min_pending_latency=0.10
2011-09-03 12:08:15 ad...@everpix.net   Changed Performance Settings
max_idle_clones=2, min_pending_latency=0.10

Then 2 days before our public launch at TechCrunch Disrupt, change of
mind: now we need a minimum of 5 instances all the time, just in case:
2011-09-10 10:16:23 ad...@everpix.net   Changed Performance Settings
max_idle_clones=5, min_pending_latency=0.10

The next morning, I look at the graph (attached to previous post),
realize it's obviously not working and decide to re-enable always-on
in billing so we at least get 3.
2011-09-11 09:47:15 ad...@everpix.net   Changed Performance Settings
max_idle_clones=5, min_pending_latency=0.10
2011-09-11 09:47:03 ad...@everpix.net   Changed Performance Settings
max_idle_clones=5, min_pending_latency=0.10

And I post to the mailing list a few minutes later at 9:53AM

I guarantee you min-instances was set to 5 in the dashboard for all
the duration of the previously attached graph :)

 I see that min-idle-instances was removed on 2011/08/31-19:49:59 and
 then set to 3 on 2011/09/11-09:47:38. So, it wasn't on when you emailed but
 is on now. Your instances graph now looks correct.

  Hi,

  Because we are about to launch our app very soon, I increased the number

  The spikes correspond to cron tasks running hourly I assume.

  it not stable at 5.

  I just activated Always On to work around the issue, so now it's back to
  3+1.

2011-09-13 Thread Jon McAlister
You are conflating min-idle-instances and max-idle-instances, which
are different concepts. My statement was only with respect to
min-idle-instances, and is still correct. min-idle-instances was
removed on 2011/08/31-19:49:59 (by you disabling Always-On) and then
set to 3 on 2011/09/11-09:47:38 (by you re-enabling Always-On).

Your previously posted graph covered the time period before this last
change, which is why it shows 0 instances at times. Your instance
graph now (or otherwise after your latest change) looks correct, with
the number of instances hovering between 3 and 6.

I typed too fast, I meant *max* idle instances in the Dashboard. Sorry
about the confusion.

That said, the description of the slider is not very clear: it's
called max which is correct from a billing perspective, but from a
functionality perspective, it really looks like you're setting the
default almost min number of idle instances, especially
considering that Always On disappears in the new system, right?
