Hola muchachos, I was checking on adding rrdcached support to the SixXS statistics daemon[1] to get it a bit out of IO hell...
$ du -hcs rrd 21G rrd 21G total if you get my drift ;) [which might be little for some folks...] But apart from: http://www.netways.de/uploads/media/Sebastian_Harl_How_to_Escape_the_IO_Hell_02.pdf I can't find any API documentation, using those APIs I googled a bit: A google(rrdc_connect site:oss.oetiker.ch) is empty. A google(rrdc_connect site:oetiker.ch) gives only the patches on the mailinglist. The Debian librrd-dev does not have anything either and I can't seem to find it in the source tarballs (see below) unless I am looking in the wrong location. Is there a small minimal example application that shows the ropes? Also, if rrdcached opens the files, how are permissions handled? Especially when the calling process runs as user X and the daemon as user Y. Or is it expected that rrdcached runs as X or at least in the right group? The "SECURITY CONSIDERATIONS" of http://oss.oetiker.ch/rrdtool/doc/rrdcached.en.html has nothing about this...
