      Description

      HI ,

      We have see a lot of false negative on ping monitoring using icmppingsec , we have see that zabbix launch the command of ping like "sh -c /usr/sbin/fping -C1 -t1000 -i0 2>&1 </tmp/zabbix_proxy_31893.pinger" , the options -i0 set fping to do all ping simultaneously , but in this configuration we have see that fping generate a lot of false positive .

       

      we have rewrite the code on function get_interval_option on file src/libs/zbxicmpping/icmpping.c   forcing it to set the minimum interval to 10ms , in this way we have solved the problem.
