    Description

      Simple Check monitors 100 hosts.

      icmpping[,4,3000,,2000]
      

      A single icmp pinger process monitors about 2 to 4 at any given time.

      debug log
      /usr/bin/fping -C4 -p3000 -t2000 -i0 2>&1 </tmp/zabbix_server_3732.pinger;
      
      debug log
      read line [ICMP Host Unreachable from 172.16.10.100 for ICMP Echo sent to xxx.xxx.xxx.2]
      read line [ICMP Host Unreachable from 172.16.10.100 for ICMP Echo sent to xxx.xxx.xxx.2]
      read line [ICMP Host Unreachable from 172.16.10.100 for ICMP Echo sent to xxx.xxx.xxx.2]
      read line [ICMP Host Unreachable from 172.16.10.100 for ICMP Echo sent to xxx.xxx.xxx.2]
      read line [xxx.xxx.xxx.1 : 5.83 5.94 6.00 5.91]
      read line [xxx.xxx.xxx.2 : - - - -]
      

      If the same fping is executed directly from the command, -i0 fails and -i1 succeeds.

      fping command
      # /usr/sbin/fping -C4 -p3000 -t2000 -i0 2>&1 </tmp/zbx_ping.pinger 
      # /usr/sbin/fping -C4 -p3000 -t2000 -i1 2>&1 </tmp/zbx_ping.pinger 
      

      Also, the same host is not always unreachable, and the timing varies.

      The -i option is set to 0 on first operation, but the automatically set 0 is unstable.
      Is it possible to automatically reconfigure the -i option or set it in the icmpping parameters?
