 Zabbix writes IP addresses to be checked by any of three //​icmpping*//​ keys to a temporary file, which is then passed to **fping**. If items have different key parameters, only ones with identical key parameters are written to a single file.\\ All IP addresses written to the single file will be checked by fping in parallel, so Zabbix icmp pinger process will spend fixed amount of time disregarding the number of IP addresses in the file. Zabbix writes IP addresses to be checked by any of three //​icmpping*//​ keys to a temporary file, which is then passed to **fping**.
