Hi,
Based on answers of my first post, I wrote a small perl script in order to find out the CPU and MEMORY used by each jail.
Here it is:
------------------------------------------------------
- jls.ps
------------------------------------------------------
#!/usr/bin/perl
@jails = `jls`;
$title = shift @jails;
chomp $title;
print $title . "\t\t%CPU\t%MEM\n";
foreach (@jails)
{
my ($jid) = /\s+(\S+)\s/;
@jexec = `jexec $jid ps -afxu`;
@mem = map {/\S+\s+\S+\s+\S+\s+(\S+)\s/} @jexec;
shift @mem;
$tot_mem = 0;
foreach (@mem) { $tot_mem = $tot_mem + $_; }
@cpu = map {/\S+\s+\S+\s+(\S+)\s/} @jexec;
shift @cpu;
$tot_cpu = 0;
foreach (@cpu) { $tot_cpu = $tot_cpu + $_; }
chomp $_;
print $_ . "\t$tot_cpu\t$tot_mem\n";
}
------------------------------------------------------
I still haven't connected anything to cacti yet, but I wanted to share that. I think it can be quite useful.
Cheers,
----------------------------------
