Well I took a look at the scripting option and assuming you meant escript,
it doesn't look like something I'll be picking up from scratch in an hour
or so ;)
I hacked port_sigar as you suggested to print the reply values to stderr
and ran it using the example.escript which is in the source directory ( I
hope that was a reasonable thing to do).
Here is the output from one of the couchbase servers:
./portsigar/example.escript
cpu_total_ms: 67285756633
cpu_idle_ms: 32306446002
swap_total: 8589934592
swap_used: 1717555200
swap_page_in: 5915867
swap_page_out: 87010188
mem_total: 4294967296
mem_used: 18446744073677623296
mem_actual_used: 18446744017909834968
mem_actual_free: 60094683944
escript: exception error: no match of right hand side value

Obviously the mem_used and mem_actual_used numbers are way off.
I dug into it deeper and it seems the calculations made by sigar are wrong
when running inside a zone.
I'll keep looking for a long term solution to that but the thing is that
these calculations in sigar haven't changed in 3 years so what changed in
2.5.1 that caused the numbers in the interface to come out screwy?
Thanks,
Yonah
