So, you have a time window of ~1h where the system is under load, right? This is somewhat different to what Ulrich had, but his approach might be useful for you, too. Something against running some monitoring and capturing the processes, process states and load say, every 5 minutes? Of course, the peaks might correlate to something in the logs - like cron, logins, logrotates or whatever. regards, Kai Dupke Senior Product Manager SUSE Linux Enterprise 13 -- Sell not virtue to purchase wealth, nor liberty to purchase power.
