icinga2通过check_ping.pl插件生成可用性监控

修改脚本：
# vi check_ping.pl（最后2行改成下面这样）
my $loss = sprintf("%.3f",(100 - (100 * $nok/$pack)));
printf("PING - Packet active = $loss%%, rta = $rta ms\n|active=$loss", $loss,$rta,$loss);
:wq
解释：
1、(100 - (100 * $nok/$pack))表示的可用性（100% - 丢包率）
2、%.3f表示保留3个小数点
3、增加|active=$loss及最后的$loss是为生成图像（grafana里用得到）
在icinga2里调用check_ping.pl插件
# vi /etc/icinga2/conf.d/templates.conf
object CheckCommand "check-ping" {
import "plugin-check-command"
command = [ PluginDir + "/check_ping.pl" ]
arguments = {
"--host" = "$address$"
"--loss" = "$loss$"
"--rta" = "$rta$"
}
}
:wq
# vi /etc/icinga2/conf.d/services.conf
apply Service "check_ping" {
import "generic-service"
check_command = "check-ping"
vars.loss="900,1000"
vars.rta="900,1000"
vars.perf = true
assign where host.vars.os == "git"
}
:wq
# service icinga2 restart
