Steps to reproduce:
#open https://www.zabbix.com/documentation/current/manual/config/items/itemtypes/simple_checks:
- open /var/log/zabbix/zabbix_server.log:
5198:20200529:191836.432 item "xxxxxxxx:icmppingloss[,100,20,50,500]" became not supported: fping failed: /usr/sbin/fping: You need i >= 10, p >= 20, r < 20, and t >= 50 5198:20200529:191836.432 item "xxxxxxxx:icmppingloss[,100,20,50,500]" became not supported: fping failed: /usr/sbin/fping: You need i >= 10, p >= 20, r < 20, and t >= 50
Problem: -i is set internally according to the ./src/libs/zbxicmpping/icmpping.c in get_interval_option:
* Comments: starting with fping (4.x), the packets interval can be 0ms, 1ms, *
* otherwise minimum value is 10ms *
******************************************************************************
...
zbx_snprintf(tmp, sizeof(tmp), "%s -c1 -t50 -i0 %s", fping, dst);
...
zbx_snprintf(tmp, sizeof(tmp), "%s -c1 -t50 -i1 %s", fping, dst);
...
else
{
*value = 10;
Expected:
Interval 
should be recalculated if for example fping chnaged version from 4.X to 3.X and server was not restarted.
Correct documentation with notes about interval used and how it's calculated.
