| Dec 16, 2012 at 22:30 | comment | added | redburn | Turns out this was swap-related after all. We increased swap space from 256mb to 512mb and since then the memory graph has been quite stable. | |
| Oct 27, 2012 at 8:23 | history | edited | redburn | CC BY-SA 3.0 | Clarified the scale of the graph (it being days, not weeks, on the x-axis). |
| Oct 25, 2012 at 11:33 | comment | added | EightBitTony | I did wonder if Munin 2 was graphing / collecting the data differently enough to result in some of the differences (smoother graph on yours), but even mine shows a drop in the middle of a cycle rather than daily. It's odd, for sure. | |

| Oct 24, 2012 at 17:02 | comment | added | redburn | @EightBitTony Thanks for sharing. Yours looks a little bit more 'natural', but I do clearly see a similar (but perhaps more predictable) pattern of drops in memory cache. | |

| Oct 23, 2012 at 22:30 | comment | added | jordanm | Is this an OpenVZ/Virtuozzo container or a real VM such as XEN or KVM? | |
