Device is "unknown" when host is on Ping only

[vpatel]

Hi Team,

I am new to cacti. I have Version 1.1.37. I don't have spine. I want to monitor hosts based on Ping and email UP/DOWN mails.

I see device "Unknown" when device availability is only on ICMP Ping and no emails. Please let me know how can i make it work with ICMP Ping only.

Also, I am getting below message for poller. I can keep poller at 5 mins but I need host UP/DOWN mails within a minute.

[root@cacti ~]# php /usr/share/cacti/poller.php
s2018/12/03 09:11:30 - POLLER: Poller[1] NOTE: Poller Int: '60', Cron Int: '300', Time Since Last: '88.42', Max Runtime '298', Poller Runs: '5'
2018/12/03 09:11:30 - POLLER: Poller[1] NOTE: Cron is configured to run too often! The Poller Interval is '60' seconds, with a minimum Cron period of '60' seconds, but only 88.4 seconds have passed since the poller last ran.

Thanks,
Viral

You must use SPINE to use ICMP ping.

Thank you very much netniV for your response. It worked great!

I have experienced that sometimes cacti sends multiple email notifications at poller interval even if its not configured for. It stops this erroneous behavior on its own after a while. Its once in a while but concern raising when in production resulting many emails. Could you please guide me how can I troubleshoot this. Your help is much appreciated in advance.
