Librenms NFsen tab not show

Hi, I’ve integrated the NFsen on Librenms. NFsen is configured and is collecting data for a device, below the rrd file in nfsen dir:
[root@ITPUBO-LOG03 live]# pwd
/var/data/nfsen/profiles-stat/live
[root@ITPUBO-LOG03 live]# ll
totale 2632
lrwxrwxrwx. 1 root root 19 16 mar 21.50 10.90.2.126.rrd -> CoreBO_pucci_it.rrd
-rw-rw-r–. 1 netflow apache 2687848 16 mar 22.00 CoreBO_pucci_it.rrd
-rw-rw-r–. 1 netflow apache 247 16 mar 22.00 profile.dat

The problem is that Netflow tab is not shown on device in Librenms, my librenms config is:
$config[‘nfsen_enable’] = 1;
$config[‘nfsen_split_char’] = ‘_’;
$config[‘nfsen_rrds’][] = ‘/var/data/nfsen/profiles-stat/live/’;
#$config[‘nfsen_rrds’][] = ‘/var/data/nfsen/profiles-stat’;
$config[‘nfsen_base’][] = ‘/var/data/nfsen/’;
$config[‘nfsen_suffix’] = “_pucci_it”;

What is wrong?
Thanks a lot!
