我正在使用派生节点来计算网络设备的带宽利用率,下面是脚本。
我正在使用 where 子句,因为我想要针对特定 Ip 的特定接口发出警报。
// database
var database = 'router'
// measurement from where data is coming
var measurement = 'cisco_router'
// RP from where data is coming
var RP = 'autogen'
// which influx cluster to use
var clus = 'network'
// durations
var period = 7m
var every = 10s
// alerts
var crit = 320
var alertName = 'cisco_router_bandwidth_alert'
var triggerType = 'threshold'
batch
|query(''' SELECT (mean("bandwidth_in") * 8) as "value" FROM "router"."autogen"."cisco_router" where host = '10.1.11.1' and ( interface_name = 'GigabitEthernet0/0/0' or interface_name = 'GigabitEthernet0/0/1') ''')
.cluster('network')
.period(7m)
.every(6m)
.groupBy(*)
|derivative('value')
.unit(1s)
.nonNegative()
.as('value')
|alert()
.crit(lambda: "value" > crit)
.stateChangesOnly()
.message(' {{.Level}} for {{ index .Tags "device_name" }} on Port {{ index .Tags "name" }} {{ .Time.Local.Format "2006.01.02 - 15:04:05" }} ')
.details('''

.log('/tmp/chronograf/cisco_router_interface_alert.log')
.levelTag('level')

.messageField('message')
.email()
.to('XXXXXXX')
|influxDBOut()

.tag('alertName', alertName)
但是当我做 kapacitor watch 并且在日志中没有显示任何错误时,它没有显示任何内容。
