NFSen Tab does not appear

Help
1

Hi all,
I have a problem: I’ve installed NFSen (I think well, because it’s running) but I cannot see the NF tab in my LibreNMS’home page.
I have edited only /opt/librenms/include/defaults.inc.php

This is my defaults.inc.php:

// NFSen RRD dir.
$config[‘nfsen_enable’] = 1;
$config[‘nfsen_split_char’] = “_”;
$config[‘nfsen_rrds’] = “/data/nfsen/profiles-stat/live/”;
$config[‘nfsen_rrds’] = “/data/nfsen/profiles-stat/live/”;
$config[‘nfsen_suffix’] = “”;

Where am I wrong? thanks a lot!!!

What do the files look like in those directories?

The config should be: $config['nfsen_rrds'][] = “/data/nfsen/profiles-stat/live/”;. You can remove one of the nfsen_rrds

3

I correct it, but without any improvement. I thought that at least a tab with “Netflow” should appear enabling NFSen, but it is not present

Thanks!

I could be wrong but I thought that was supposed to be in config.php

5

No, now it is changed and every kind of information is written on defaults.php.inc. On config.php there are no lines like those ones I posted

6

you have to add them into config.php

7

I did it and I reboot the web server with “sudo shutdown -r now”, but no tab appears there, do you know if there should be a new tab or something integrated in another page?

8

I believe so in the device itself. when you click on the device then tab called Netflow.

I have only these tabs

then im guessing that something is not set correctly in config.php

or

If you look in html/pages/device.inc.php you can find the code where it tries to convert librenms device hostname to a nfsen rrd file. It does this in three steps on the hostname:
1- regex replace any “.” with the nfsen_split_char
2- strstr to strip off the nfsen_suffix from the end
3- add $config[‘nfsen_rrds’] the the beginning and “.rrd” to the end

Since you seem to be saying that your nfsen rrd files have your domain name (_example_net), I think your nfsen_suffix should = “”. But you tried that.

These are the lines in html/pages/device.inc.php about nfsen

    if ($config['nfsen_enable']) {
        if (!is_array($config['nfsen_rrds'])) {
            $config['nfsen_rrds'] = array($config['nfsen_rrds']);
        }

        foreach ($config['nfsen_rrds'] as $nfsenrrds) {
            if ($nfsenrrds[(strlen($nfsenrrds) - 1)] != '/') {
                $nfsenrrds .= '/';
            }

            $nfsensuffix = '';
            if ($config['nfsen_suffix']) {
                $nfsensuffix = $config['nfsen_suffix'];
            }

            if (isset($config['nfsen_split_char']) && !empty($config['nfsen_split_char'])) {
                $basefilename_underscored = preg_replace('/\./', $config['nfsen_split_char'], $device['hostname']);
            } else {
                $basefilename_underscored = $device['hostname'];
            }

            $nfsen_filename           = preg_replace('/'.$nfsensuffix.'/', '', $basefilename_underscored);
            if (is_file($nfsenrrds.$nfsen_filename.'.rrd')) {
                $nfsen_rrd_file = $nfsenrrds.$nfsen_filename.'.rrd';
            }
        }
    }//end if

I don’t know where to modify

12

and your config.php?

13

It’s only composed by DB config, authentication model and those lines I copied from your suggestion

14

only lines I suggested were copied straight from you – so they could be wrong - double check in the doc.

15

Yes, but enabling nfs (with $config[‘nfsen_enable’] = 1; ) I think it should enabling the tab, isn’t it?

16

Don’t change defaults.inc.php, you need to put the config you’ve changed into config.php

Can you show an example of the files in the directory you’ve pointed to?

Was this issue ever resolved?

was it? I’m having a similar issue, Netflow tab not appearing?
