    Default Free Memory Alert doesn't seem to work right

    I appreciate the new alert features in Untangle, but the default memory alert doesn't seem to be working right.

    The default rule is to alert when free memory is less than .1. What is .1? is it .1%. Is it .1 Gb? Whatever it is, apparently 114MB is low enough to trigger it on a 2GB system. I'm continually getting alerts from this and in the alert e-mail the free memory is around 114MB. Unfortunately, there doesn't seem to be a lot of explanation about these alerts or how to add or modify them.

    I've disabled the alert for now, and the fact that the box probably needs more ram is beside the point.

    Thanks

    .1 is Free Memory Percentage. .1 = 10% So the alert is sent if there is less than 10% of total memory free.

    For your system, an alert is sent when less than 200MB is available (2000MB x 10% = 200MB).

    We are in the process of documenting the alerts rules on the Wiki.

    Thanks. That helps. I wonder why the alert is always around 114MB when it should be around 200MB, I would think.

    It's not exactly 200MB. The alert is sent when the monitor cycles and detects it less than 10%. Memory dips can happen in chucks instead of a continuous downward slope.
