我正在尝试创建一个(golang)结构来处理通过 http 发送的 bosun 警报。它保存警报详细信息,最重要的是,有关eth0相应主机的 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"`}对应的模板如下所示: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 = ``}但是,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我在 IpMac 字段中使用 [] 字符串,因为我无法将 eth0 IP 与其以太网地址隔离开来。有什么办法可以做到这一点?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"] }这是我配置的警报: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}

您确定有问题的主机是 eth0 设备(并且 bosun 已索引该元数据)吗?nil 表示找不到条目。
以下对我有用:
template test {
subject = {{ .GetMeta "" "addresses" (printf "host=%s,iface=eth0" .Group.host) }}
}
