Netflow tab not appearing?

looks like this question has been asked a fair amount but the answer is elusive, or at least it’s not posted if it works…the netflow tab does not show up after editing /opt/librenms/config.php with these entries:

enable NFSen

$config[‘nfsen_enable’] = 1;

configure NFSen

$config[‘nfsen_splitchar’] = ‘’;
$config[‘nfsen_rrds’][] = ‘/data/nfsen/profiles-stat/live/’;
$config[‘nfsen_rrds’][] = ‘/data/nfsen/profiles-stat’;
$config[‘nfsen_base’][] = ‘/data/nfsen/’;

$config[‘nfsen_last_max’] = 153600;
$config[‘nfsen_top_max’] = 500;
$config[‘nfsen_top_N’]=array( 10, 20, 50, 100, 200, 500 );
$config[‘nfsen_top_default’]=20;
$config[‘nfsen_stat_default’]=‘srcip’;
$config[‘nfsen_order_default’]=‘packets’;
$config[‘nfsen_last_default’]=900;
$config[‘nfsen_lasts’]=array(
‘300’=>‘5 minutes’,
‘600’=>‘10 minutes’,
‘900’=>‘15 minutes’,
‘1800’=>‘30 minutes’,
‘3600’=>‘1 hour’,
‘9600’=>‘3 hours’,
‘38400’=>‘12 hours’,
‘76800’=>‘24 hours’,
‘115200’=>‘36 hours’,
‘153600’=>‘48 hours’,
);

$config[‘nfdump’] = ‘/usr/bin/nfdump’;

nfcapd is running and posting data
rrdtools is graphing with output
source ident in nfsen is the same as in Librenms (symlinked in live directory)
with that being said why would the netflow tab not show up in the UI?

Probably it can’t find the rrd files, make sure you have everything configured correctly.

“Probably it can’t find the rrd files”
The paths in config.php match what’s on the device, unless there is another file to edit.

Maybe you can tell me what to look for?
The source in LibreNMS is 10.0.1.1 but NFSen won’t take ip4 addresses so I symlinked 10.0.1.1.rrd to the nfsen generated gateway.rrd so that the rrd file and the LibreNMS source match. Is this correct? Also I have a question about this entry in /opt/librenms/config.php “$config[‘nfsen_suffix’] = “_yourdomain_com”;” what should I replace/append “_yourdomain_com” with? Can you show me an example?

If your devices are called switch-01.google.com you have to set the nfsen_suffix to _google_com
