You're heading a little further than I was originally. I was originally only looking at the very bottom layer of the stack - just dumping enough raw data both regularly enough and sufficiently completely that a range of higher-level tools had something to chew on. My experience here is that munging data into rrd is relatively expensive, at least on the scale we're looking at here. I suspect that for rrd collection you would have to identify the subset of statistics of interest, and just keep those. Or are you suggesting we rrd everything? (That won't work for any meaningful definition of everything: just consider the I/O statistics for NFS mounts in an environment with an active automounter.) And if just a subset, can we identify that? -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/ _______________________________________________ sysadmin-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/sysadmin-discuss
