我正在尝试创建一个(golang)结构来处理通过http发送的bosun警报。它包含警报详细信息,最重要的是,它包含相应主机的eth0
IP地址。
/* This struct is defined as per the notification defined in bosun config */
type BosunAlert struct {
AckUrl string `json:"ack"`
AlertName string `json:"alert_name"`
LastStatus string `json:"last_status"`
IpMac []string `json:"ip,omitempty"`
}
相应的模板如下所示:
template template.bosun_listener {
subject = `{
"ack":"{{.Ack}}",
"alert_name":"{{.Alert.Name}}",
"last_status":"{{.Last.Status}}",
"ip":{{ .GetMeta "" "addresses" (printf "host=%s,iface=eth0" .Group.host) }}
}`
body = ``
}
然而,我收到此错误:
info: check.go:305: alert.network{host=147210308125790,ifName=server-1609}:
template: template.bosun_listener:6:12: executing "template.bosun_listener" at
<.GetMeta>: error calling GetMeta: redigo: nil returned
我正在为IpMac字段使用[]字符串,因为我无法将eth0 IP与其以太网地址隔离开来。
有什么办法吗?
编辑: 这是我得到的输出:
"ack":"http://localhost:8070/action?
key=alert.network%7Bhost%3D147210308125790%2CifName%3server-1609%7D&type=ack",
"alert_name":"alert.network", "last_status":"critical", "ip":
["172.31.40.31/20","fe80::61:adff:feb1:1f5b/64"] }
这是我配置的提醒:
alert alert.network {
runEvery = 5
$ip = ""
template = template.bosun_listener
$usage = avg(q("avg:rate:container.net.bytes{host=*,ifName=server*}", "5m", ""))
crit = $usage > 100
critNotification = notification.test
}
答案 0 :(得分:2)
您确定有问题的主机是eth0设备(并且bosun已将该元数据编入索引)吗?零意味着它无法找到该条目。
以下适用于我:
template test {
subject = {{ .GetMeta "" "addresses" (printf "host=%s,iface=eth0" .Group.host) }}
}
