To all those involved in this. More up-to-date: arc_summary.pl r182 I have done some more minor formatting with the heading section. I have added some L2 ARC stats. Adjusted called binaries to have full paths for the moment until I get around to fixing it a little more. Not having the full path caused some frustrations with emailing the output while running from cron. If this will be a problem with anyone running it and you come across errors where something can not be executed please be patient as I will have this adjusted soon. arcstat.pl: Please update the WiKi with the missing URL, I uploaded the original FreeBSD modified copy of arcstat.pl script to the same location as arc_summary.pl in case anyone wants to grab that file for FreeBSD while they are their. I have also signed this file with my public key. I won't be making any mods to this script as I see it works as intended. I may be persuaded in the future to make adjustments to keep it working and small bug fixes. http://jhell.googlecode.com/files/arc_summary.pl http://jhell.googlecode.com/files/arcstat.pl MD5 (arc_summary.pl) = 6587be39266bd131ed5f4611f321c9e2 SHA256 (arc_summary.pl) = fea99963562e1caee01d6ccd9af1b592cb18fcfaf81308bd1ee21c546c8290ad SIZE (arc_summary.pl) = 12875 MD5 (arcstat.pl) = 9b7d7b4d52ba997c7c59bc0afaca8aa9 SHA256 (arcstat.pl) = b97fc59460468bb2bab6d53009e67f2de87fd5817e7b5656266ea4fd75079b2a SIZE (arcstat.pl) = 8172 Best regards.
