Possible to monitor disk space remaining?

I'm currently using EventSentry to alert me if drives on Windows 2008/2012 virtual machines are running below 5% available space. Can I use LEM to replace EventSentry?

  • It is possible to make Windows log a disk space alert which LEM can then normalize ( I haven't checked this for Windows 2012)

    Window 2003 and 2008 including R2: You will have to create 2 DWORDs. DiskSpaceThreshold and LowDiskSpaceMinimum. These DWORDs do not exist by default, and will require a reboot to take effect.

    DiskSpaceThreshold refers to the free space threshold (http://technet.microsoft.com/en-us/library/cc786996(v=ws.10).aspx)

    LowDiskSpaceMinimum refers to the threshold in MB below which the alert (http://technet.microsoft.com/en-us/library/cc784049(v=ws.10).aspx)

    Both conditions will be evaluated unless LowDiskSpaceMinimum is set to 0. They DWORDs must be added under this registry key

    HKEY_LOCAL_MACHINE

    \SYSTEM

    \CurrentControlSet

    \Services

    \LanmanServer

    \Parameters

    • The disk space is checked every 5 minutes and an Event ID 2013 is generated in the System log if the conditions are met
    • The Event is not generated multiple times if the free space continues to fall. A fresh event is generated only when the condition is remediated, and the thresholds are breached again

    In LEM, the Event will appear as a ServiceWarning event with a ProviderSID of srv 2013.

    What else do you currently monitor in EventSentry?

  • In addition to monitoring for low disk space I'm using it to monitor failed logins and the basic set of alerts that come with EventSentry. I'm hoping to eliminate EventSentry when I get LEM setup.

    Thanks for the post!
