I've always liked sysstat for this, as its almost totally invisible in terms of system load but has a wealth of information for diagnosing chronic problems. As was pointed out elsewhere, this doesn't show you the brief spikes, but getting those involves a lot more data collection. :-P So if a customer is taken on, then installing something like sysstat should be one of the first recommendations. Of course, there's also Landscape, if you're so inclined to hand over a little cash, you get a lot of this built in (and a lot more ;) -- ubuntu-server mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
