Variables in perl script
Hi Chaps,
Im after some advise with a script i've written however doesnt appear to work how I would like.

Basically I have a perl script which sucessfully pulls an expect script to login to multiple nodes and obtain some output from the nodes (total number of nat ports that are in use for the relivant pool on that node).

What I want to archieve is a list of the pools from each node with the number of ports in use, They if a single nat pool is using less than x number of ports to email me.

Firstly my perl script doesn't seem to output the details as I would like, for each pool i want the line to show the node name, then the port details (as per the below, what you will notice is in the output below the node name appears to be on the line above the port details) possibly due to control characters but not sure how is best to deal with this ?

Script:
Code:
#!/usr/bin/perl -w
use Term::ANSIColor;
use strict;
use constant DEBUG => 1;
my $pool0 = "";
my $pool1 = "";
my $filename = "list.txt";
open(my $fh, "<", $filename) or die "couldn't read file";
while (my $line = <$fh>){
        for (`../user/test2.sh $line`) {
                                if (/pool0\s\S+\s+\S+\s+\S+\s+(\S+)/) {
                                        $pool0 = $1;
                                print color("red"), "$line pool0 ports in use $pool0\n", color("reset");
                                }
                                if (/pool1\s\S+\s+\S+\s+\S+\s+(\S+)/) {
                                        $pool1 = $1;
                                print color("red"), "$line pool1 ports in use $pool1\n", color("reset");
                                }

                        }
}
exit 0;

Output with new lines between node name and value although I want it all in one line.

Code:
RN001
 pool0 ports in use 415963
RN001
 pool1 ports in use 425610
RB001
 pool1 ports in use 323477
RB001
 pool0 ports in use 325010

Also could anyone help in regards to how i can I check multiple nat pool values that the script puts into variables (pool0, pool1 etc) to send an email to me if any of them fall below a certain number of ports in us.

I want an email on a per node basis rather than per pool, It should only generate an email if it falls below the configured value.

Thanks for the help

numastat

NUMACTL(8)						   Linux Administrator's Manual 						NUMACTL(8)

NAME

       numastat - Print statistics about NUMA memory allocation

SYNOPSIS

       numastat

DESCRIPTION

       numastat  displays  NUMA  allocations  statistics from the kernel memory allocator.  Each process has NUMA policies that specifies on which
       node pages are allocated. See set_mempolicy(2) or numactl(8) on details of the available policies.  The numastat  counters  keep  track	on
       what nodes memory is finally allocated.

       The counters are separated for each node. Each count event is the allocation of a page of memory.

       numa_hit is the number of allocations where an allocation was intended for that node and succeeded there.

       numa_miss shows how often an allocation was intended for this node, but ended up on another node due to low memory.

       numa_foreign  is  the  number of allocations that were intended for another node, but ended up on this node.  Each numa_foreign event has a
       numa_miss on another node.

       interleave_hit is the number of interleave policy allocations that were intended for a specific node and succeeded there.

       local_node is incremented when a process running on the node allocated memory on the same node.

       other_node is incremented when a process running on another node allocated memory on that node.

SEE ALSO

       numactl(8) set_mempolicy(2) numa(3)

NOTES

       numastat output is only available on NUMA systems.

       numastat assumes the output terminal has a width of 80 characters and tries to format the output accordingly.

EXAMPLES

       watch -n1 numastat
       watch -n1 --differences=accumulative numastat

FILES

       /sys/devices/system/node/node*/numastat

BUGS

       The output formatting on machines with a large number of nodes could be improved.
