Is there alternative to check_host_alive not working?
Posted: Wed Mar 07, 2018 3:48 pm
Hi,
I typically use check_host_alive command configured in the CCM to monitor the target server if it is up or down.
However, I just came across some redhat servers which are up, but the check_host_alive command results in the message "CRITICAL - 10.155.100.101: rta nan, lost 100%" making me thinking that they are down. I realized that I'm unable to ping these servers, but I can SSH to them and logon.
Therefore, I believe there must be a firewall that has ICMP traffic blocked and SSH port allowed.
Is there an alternative way for me to monitor these servers if they are up without using the check_host_alive command?
thanks.
