Yeah, SAR just runs out of cron and collects data every 10 (configurable) minutes. I think this would be the most reliable way to track the highest level swap has reached. I think in theory the Linux kernel is supposed to gradually reduce swap when it has the cycles available (although I agree it never seems to happen). If you were using VDISKs for swap I think you could check the size of those because they should grow but not shrink. In which case the highest level the guest got to (since last logon) would be the current size of the VDISK. -Chris ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
