Wrong return from perf perf-object-get-instances and cMode DOT

[ Edited ]

Hi,

 

I try to get some info from my filers like cpu_busy, total_ops, latency...

I wrote a perl script using the ONTAPI but for example when I get the system counter cpu_busy, it show me a large number instead of utilisation %, is it normal ?

 

my $api = new NaElement('perf-object-get-instances');

my $xi = new NaElement('counters');
$api->child_add($xi);
$xi->child_add_string('counter','cpu_busy');

my $xi1 = new NaElement('instance-uuids');
$api->child_add($xi1);

$xi1->child_add_string('instance-uuid',$node_uuid);
$api->child_add_string('objectname','system');

my $xo = connect_filer($filer_address)->invoke_elem($api);
my $instances = $xo->child_get("instances");

if($instances){
my $instance_data = $instances->child_get("instance-data");
my $counters = $instance_data->child_get("counters");
if($counters){
my $counter_data = $counters->child_get("counter-data");
if($counter_data){
my $rounded_busy = $counter_data->child_get_int("value");
$cpu_return{$node_name} = $rounded_busy;
}
}
}

 

I have the same issue when I use nfs_ops, it give me total nfs operation sinc last boot instead of nfs operation per second...
