For example, does it support VT-d/VT-x? Well, in the command line, you can find out what processor it has and look it up on Intel's ark site.
For example, if you had an i7 3770k, you could go and get the full specs at by googling "ark 3770k" which gives you a link to the specs at : http://ark.intel.com/products/65523
In linux you can cat /proc/cpuinfo.
Well, I will show you the OSX equivalents. Instead of cpuinfo, we have sysctl To get the model name
in Linux In linux:
grep "model name" /proc/cpuinfo
In OSX, it is:
sysctl -n machdep.cpu.brand_string
To get full CPU info Linux:
cat /proc/cpuinfo
sysctl -a | grep machdep.cpu
Want to know the core count and threads, you do another pipe grep. In OSX:
sysctl -a | grep machdep.cpu | grep core_count
sysctl -a | grep machdep.cpu | grep thread_count
Here is a full example:
semi-related question: we use Nagios to monitor some hosts, particularly for the presence of active NFS mounts -- on Linux, the plugin refers to /proc and /etc/mtab. I'm stumped about the "equivalent" on OSX. Any pointers?
ReplyDeleteI've only use nagios on Linux. never on OSX. have you tried nagios/plugins/check_disk -w 15% -c 10% -p /a_mount_point . Just check for the existing of the path. OSX also has a command, showmount you can look into
DeleteWe want to make sure the system itself sees the mount and that it's NFS-functional. Seems OSX has to do things so differently (ie: no /proc or /etc/mtab to refer to). I even asked Apple Support and they were clueless. I'm awaiting an Apple Developer Subscription to be activated so I have access to those resources. Thanks :-)
ReplyDeleteNice post...thanks for sharing.

Why sysctl -a | grep machdep.cpu | grep core_count
ReplyDeleteWhy not simply sysctl machdep.cpu.core_count
