    I know that I have plenty of disk space.

    But, I am finding that my server slooooows way down at times and I need to figure out what the bottleneck is.

    I've tuned up mysql, ensim, mailman, and eliminated some of the piggy cpanel features that no one uses anyway.

    Got some good improvement.

    Now, I need to figure out whether the bottleneck is memory or cpu.

    I have no idea how to track this other than that I see both memory and cpu warnings in cpanel when the slowdowns occur (Well, sometimes it is one or the other!)

    I don't think the problem is bandwidth, Although that is a possibility.

    So, how do I monitor cpu, memory, and bandwidth useage?

    What I'd like to see is a chart with the following headings (or acquire the informatioin to build this chart):

    date & time in minutes / CPU used / bandwidth used / memory used / paging

    Since these slowdowns usually occur for extended periods of time, a scale in minutes or even two or three minutes would at least get me started.

    Any ideas about how to acquire this information?

    I'm on Red Hat Fedora if that makes a difference.

    Anybody ever heard of a monitor that will record the time of day and the cpu, memory, paging, and bandwidth when any of them exceed specified limits?

    Try turning off SPAMD from WHM then see what happens. SPAMD is useless, a big server hog and nobody really needs it. Not if your filtering all inbound/outbound mail via SA serverwide why would SPAMD need to be running? :confused: Then the messages are again scanned for those who have enabled SA from their control panel. Thats where SPAMD kicks in!

    I guess I don't understand Spamd vs Spam Assassin

    Is spamd different from spamassassin?

    Does spamd run server wide on all mailboxes seperate from spam assassin?

    Does spamd catch anything different from spam assassin?

    What technology is spamd? I assume it is not Bayesian like spam assassin.
