icinga2通过check_ping.pl插件生成可用性监控

下载地址：

https://exchange.nagios.org/directory/Plugins/Network-Protocols/ICMP/check_ping-2Epl/details

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
