<snip> The standard 4.3.0 beta adds caching of RRD file updates, and this has a significant impact on the I/O load of the server - essentially, it means that hobbitd_rrd caches up to 12 updates (= 1 hour) before it does an actual update of the RRD file. Since the amount of disk I/O is almost identical whether you're doing one data update or 50, this cachingeliminates about 90% of your disk I/O on the RRD files. So that would be the simplest solution to implement.
I am running 4.3.0-0.20080103 so quite an out of date version. However I would be interested in learning this. Would I have to upgrade my hobbit / xymon installation to get this feature? What version contains it? How do I enable it?
Currently I have > 100,000 rrd files and the server sits with between 20% and 50% i/o wait. Performance is acceptable I guess but anything to improve this would be welcome.
