Device polling faills

Dear all,

I have a network of up to 2000 devices, and I am having some troubles since most of the devices are not polling correctly.

Below there is represented my cron.job file:

I have to comment that I have set the ping check to 1 minute and my fping configuration is the following:

I set ping_rrd_step
$config[‘ping_rrd_step’] = 60;

,updated the rrd files
./scripts/rrdstep.php -h all

and also the cron:
* * * * * librenms /opt/librenms/ping.php >> /dev/null 2>&1

Finally, I update the config.php:

$config['fping'] = "/usr/sbin/fping";
$config['fping_options']['timeout'] = 500;
$config['fping_options']['count']   = 5;
$config['fping_options']['interval'] = 500;

Furthermore, when I check the validation file (validate.php), these are the results:


I have checked the cron job and anything seems to setup incorrectly. Moreover, in the web UI in the poll-log I see the pooler is updating every minute, so I do not know how to solve it and I am a bit lost. I will be very grateful if someone could help me.

Best regards,

Sebastia

Are you polling 2k devices from only 1 poller?

If yes, unless the lnms server is a really good server, and I mean a VERY GOOD SERVER, thats your issue.

Take a look to https://docs.librenms.org/Support/Performance/

and to https://docs.librenms.org/Extensions/Distributed-Poller/

I have 2k devices, but I still just added 300. I will take a look.
Thanks for the answer.
