[nagios] CRITICAL – popen timeout received, but no child process

CRITICAL – popen timeout received, but no child process.

需要指定使用 ipV4 參數來執行 check_ping 的檢查

修正 nagios 的 command.cfg check_ping 命令的設定僅使用IPV4來檢查

define command{
        command_name    check-host-alive
        command_line    $USER1$/check_ping -4 -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5 -4
}
