# Reboot Boards due to low Memory with notification - MikroTik Script RouterOS

    set this in scheduler to get lost memory back and to get a reboot when it needs to do this

    :global datum [/system clock get date];
    :global time [/system clock get time];
    /system resource
    :if ([get free-memory]< 25000) do=[
    /tool e-mail send server=*.*.*.* to="alert@yours.net" subject=[/system identity get name]
    from="alert@yours.net" body=(" on $datum at $time the memory on this repeater got to ", [/system resource
    get free-memory])
    /system reboot;
    ]};
    on the if statement you will need to set the 25000 depending on board type IE 532a = 25000 153 = 12000 and so on I put this in scheduler to run at 3am once a day

    Using percentages

    :global datum [/system clock get date];
    :global time [/system clock get time];
    :local percentfree ((100 * [/system resource get free-memory]) / [/system resource get total-memory])

    /system resource
    :if ($percentfree < 5) do={
      /tool e-mail send server=*.*.*.* to="alert@yours.net" subject=[/system identity get name] from="alert@yours.net" body=(" on $datum at $time the memory on this repeater got to ", [/system resource get free-memory])
      /system reboot;
    };
    Will notify and reboot if free memory < 5%
