High ICMP ping loss - icmppingloss

[me2017]

Since updating zabbix to 3.4 I'm seeing a persistent 'Problem' of 'High ICMP ping loss' This is reported only on a single host, the zabbix server.

I'm having difficulty diagnosing the root cause. I've tried to use 'zabbix_get' but my results are the same as what appears in the post below 'ZBX_NOTSUPPORTED: Unsupported item key.'

I have removed and replaced the template, and also verified fping location and permissions, but this resulted in the same 'Problem' of 'High ICMP ping loss' reappearing.

What else can I do to diagnose the issue?

On the host interface for the server, it it using IP or DNS? Is the IP or DNS correct? Is it self monitored or monitored by a proxy?

zabbix_get only works for zabbix agent items, icmpping* are simple checks.

Thank you for the clarification on 'simple checks.' I didn't realize this was the case.

As for the host interface, I think you're referring to 'Configuration -> Hosts' If so, the host is configured with just the hostname / DNS. I don't have a proxy in place so it's self monitored.

I will try replacing DNS as the interface and use IP.

Again, of all the items/triggers I have set in this environment, this is the only one failing.

I seem to remember long ago that some hardware couldn't ping it's own public interface, but I haven't seen that recently. I always set my server and proxy as the localhost IP.
