Since Solaris is all but dead at this point, this library is no longer being actively maintained, except perhaps for the occasional doc update. If you wish to take over maintenance, please send me an email offline and we can discuss a transfer of the repository.
A Ruby interface for the Solaris kstat library.
Solaris 8 (SunOS 2.8) or later.
gem install solaris-kstat
require 'solaris/kstat'
require 'pp'
include Solaris
k = Kstat.new('cpu_info', 0, 'cpu_info0')
pp k.record
{'cpu_info'=>
{0=>
{'cpu_info0'=>
{'chip_id'=>0,
'fpu_type'=>'sparcv9',
'device_ID'=>0,
'cpu_type'=>'sparcv9',
'implementation'=>'Unknown',
'clock_MHz'=>502,
'state_begin'=>1105974702,
'state'=>'on-line'}
}
}
}
Kstat.new(module=nil, instance=-1, name=nil)
Creates and returns a Kstat object. This does not traverse the kstat chain. The Kstat#record method uses the values passed to actually retrieve data.
You may specify a module, an instance and a name. The module defaults to nil (all modules), the instance defaults to -1 (all instances) and the name defaults to nil (all names).
Kstat#record
Returns a nested hash based on the values passed to the constructor. How deeply that hash is nested depends on the values passed to the constructor. The more specific your criterion, the less data you will receive.
The following names will not return any meaningful value:
- kstat_headers
- sfmmu_global_stat
- sfmmu_percpu_stat
None.
Please see the Notice at the top regarding the status of this project.
I noticed that results from the cpu_stat module differ from the output of the 'kstat' command line tool. I am convinced that my code is correct and that there is a bug in the Solaris::Kstat Perl module. Unfortunately, the source for the version of the Solaris::Kstat Perl module that works on Solaris 8 and later is not available (the version on CPAN only works on Solaris 6 and 7).
See http://tinyurl.com/karxw for more details.
Thanks go to Charlie Mills for help with the 'volatile' issue for the original C code.
