check\_icmp should be able to handle this and ping both addresses by adding a second one to the -H parameter and ```auto -m number of alive hosts required for success ``` > **check\_icmp -H 8.8.8.8 9.2.5.99 10.10.10.10 -m 2** > > ```auto > ./check_icmp -H 8.8.8.8 9.2.5.99 10.10.10.10 -m 2 > OK - 8.8.8.8: rta 9,166ms, lost 0% :: 9.2.5.99: rta nan, lost 100% :: 10.10.10.10: rta 19,070ms, lost 0% > |8.8.8.8rta=9,166ms;200,000;500,000;0; 8.8.8.8pl=0%;40;80;; 8.8.8.8rtmax=9,549ms;;;; 8.8.8.8rtmin=8,910ms;;;; 9.2.5.99rta=0,000ms;200,000;500,000;0; 9.2.5.99pl=100%;40;80;; 9.2.5.99rtmax=0,000ms;;;; 9.2.5.99rtmin=0,000ms;;;; 10.10.10.10rta=19,070ms;200,000;500,000;0; 10.10.10.10pl=0%;40;80;; 10.10.10.10rtmax=20,432ms;;;; 10.10.10.10rtmin=18,516ms;;;; > > ``` But there is an issue with `check_icmp` if it come from the `nagios-plugins` package (on CentOS at least), that the calculation of the `min alive` is not working. I already opened a github issue, but no response until now: [https://github.com/nagios-plugins/nagios-plugins/issues/404](https://github.com/nagios-plugins/nagios-plugins/issues/404) Therefore on my CentOS system I switched to `check_mping` [https://exchange.icinga.com/exchange/Ping%20of%20multiple%20Hosts%20via%20icmp%20protocol](https://exchange.icinga.com/exchange/Ping%20of%20multiple%20Hosts%20via%20icmp%20protocol) --- _[View the full topic](https://community.icinga.com/t/dependency-with-two-parents/717)._
