My Observium host currently has 1.2GB in use - what are you doing to that poor thing that it has 10 gigs in use during normal operation?! :-)
Simon,
The RAMdisk only takes up its full size when you fill it up - but when it's full, it's just full like a full disk. No more new RRDs created. If it's not being shown in Observium, it's likely to be matching something in an ignored array I'd think? Observium can definitely monitor tmpfs, as long as your snmp reports it through the correct tables.

Much more RAM, in fact you may already be knocking your system performance if you only have 12GB in the machine. I've got 12GB allocated to my observium VM, and the system is using 9-10GB of RAM just for regular operation. And then when I do this: root@observium:/opt/observium# du -hs rrd 27G rrd
Yeah, I'd have to allocate at least 40GB of DRAM to the VM in order to do the ramdisk thing, and that's kinda difficult to do when the VMhost only has 16GB of physical memory installed. Oops.

Hi All,
just moved our RRDs to tmpfs storage, and WOW I noticed a speed difference, not only in the graphs, but also in the IO load
should of looked at http://observium.org/docs/persistent_ramdisk/ in the past DOH!
however i’ve just noticed the observium isn’t showing it as a storage mount?
can observium monitor actually monitor it at all ?
also I’ve set my limit at 10GB as the server has 12GB of RAM, and the RRD folder is currently at 6.8GB
bit of a stupid question but what happens if I’m close to the limit? as i knackered? more RAM server?
regards
