That's a good idea, I'll try that next week.
Thanks!

Yeah, this doesn't make much sense to me either since,
as you say, you should be seeing some metrics upon
occasion. But do note that the underlying cache only gets
filled when getting documents to return in query results,
since there's no autowarming going on it may come and
go.
But you can test this pretty quickly by lengthening your
autocommit interval or just not indexing anything
for a while, then run a bunch of queries and look at your
cache stats. That'll at least tell you whether it works at all.
You'll have to have hard commits turned off (or openSearcher
set to 'false') for that check too.

Yes, we are softCommit'ing every 1000ms, but that should be enough time to
see metrics though, right? For example, I still get non-cumulative metrics
from the other caches (which are also throw away). I've also curl/sampled
enough that I probably should have seen a value by now.
If anyone else can reproduce this on 4.3.1 I will feel less crazy :).

It's especially weird that the hit ratio is so high and you're not seeing
anything in the cache. Are you perhaps soft committing frequently? Soft
commits throw away all the top-level caches including documentCache I
think....

Thanks Otis,
Yeah I realized after sending my e-mail that doc cache does not warm,
however I'm still lost on why there are no other metrics.
Thanks!

Hi Tim,
Not sure about the zeros in 4.3.1, but in SPM we see all these
numbers are non-0, though I haven't had the chance to confirm with
Solr 4.3.1.
Note that you can't really autowarm document cache...

Hey guys,
This has to be a stupid question/I must be doing something wrong,
but
after
frequent load testing with documentCache enabled under Solr 4.3.1
with autoWarmCount=150, I'm noticing that my documentCache metrics
are
always
zero for non-cumlative.
At first I thought my commit rate is fast enough I just never see
the non-cumlative result, but after 100s of samples I still always
get zero values.
Here is the current output of my documentCache from Solr's admin
for 1
core:
"

"
The cumulative values seem to rise, suggesting doc cache is
working,
but
at
the same time it seems I never see non-cumlative metrics, most
importantly
warmupTime.
Am I doing something wrong, is this normal/by-design, or is there
an
issue
here?
Thanks for helping with my silly question! Have a good weekend,
Tim
