Hello please help me with the best alert rule for new fast-ping checks.

I did this steps.

Set ping_rrd_step

$config[‘ping_rrd_step’] = 30;
Update the rrd files

./scripts/rrdstep.php -h all
Update cron (removing any other ping.php or alert.php entries)

          • librenms /opt/librenms/ping.php >> /dev/null 2>&1
          • librenms sleep 30 && /opt/librenms/ping.php >> /dev/null 2>&1
          • librenms sleep 15 && /opt/librenms/alerts.php >> /dev/null 2>&1
          • librenms sleep 45 && /opt/librenms/alerts.php >> /dev/null 2>&1

$config[‘fping_options’][‘retries’] = 2;
$config[‘fping_options’][‘timeout’] = 500;
$config[‘fping_options’][‘interval’] = 500;

So I am done with this.

For now I am using this alert rule

You need to change there the Delay. As you are doing 30 seconds check, set it up to 30s

I edited this. Thank you. I knew that there is something what i forgot to edit.

You may want to have the delay at a multiple of 30s to avoid annoying quick downs, depends on your network.

Hello @jozefrebjak,
I am also testing the fast-ping new feature. However, strangely I’m getting a lot of false alarms, alert still triggered when device status has changed to up and other problems. Please refer here for my help ticket.

Just wondering how it is going on your side? Have you put it on production? Is there any problems?

It would be very appreciated if you could share your experiences with me.
Thanks,
Roger
