"disk only" mode cache hits are not counted in statistics about nuster HOT 10 CLOSED

@netrixken Well, it's hard to say. Higher values allow more cache and lower values allow more sessions to coexist in the same time. I'd suggest you start with half of the RAM and test.

@zoltanbalog79 Thanks.

Currently, disk support in stats and purge is not yet finished. (almost finished purge, testing...)

@zoltanbalog79 fixed in master, thanks

from nuster.

this bug still exists in 3.2.0.19. /tmp/cache is empty so cache hits always 0.

Confirmed break on disk only mode, but works on disk sync mode

@netrixken fixed in v3.2.1.19

It worked now. I delete these leftover haproxy configuration from nuster config. Thank you very much!

    chroot      /var/lib/haproxy
    user        haproxy
    group       haproxy

Now, only used_mem is still always 0. Or disk cache not counted as used_mem?

from nuster.

@netrixken

only used_mem is still always 0. Or disk cache not counted as used_mem?

disk only mode does not use memory, except temporary memory.

chroot      /var/lib/haproxy

If you have this setting, the cache file is stored into /var/lib/haproxy/tmp/cache (chroot-dir + cache-dir)

from nuster.

If for example i have 100 MB RAM, how much the biggest data-size I can set? Thanks @jiangwenyuan

from nuster.

@netrixken I'm closing it now, feel free to reopen the issue if anything wrong
