1.panic: duplicate metrics collector registration attempted
重复注册。
错误代码如下
| promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k1": "v1"},
})
promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k1": "v1"},
})
|
但是这样是可以的（value不一样）
| promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k1": "v1"},
})
promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k1": "v2"},
})
|
2.panic: a previously registered descriptor with the same fully-qualified name as Desc{fqName: "name", help: "", constLabels: {k2="v2"}, variableLabels: []} has different label names or a different help string
name一样但是labels的key不一样也会导致报错。
特别注意，label的key必须是完全一样
错误示例：
| promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k1": "v1"},
})
promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k2": "v2"},
})
|
| promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k1": "v1"},
})
promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k1": "v1", "k2": "v2"},
})
|
当name一样，help不一样也会导致报错
| promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
Help: "help",
ConstLabels: prometheus.Labels{"k1": "v1"},
})
promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
Help: "help1",
ConstLabels: prometheus.Labels{"k1": "v2"},
})
|
正确示例：
| promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k1": "v1", "k2": "v2"},
})
promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k1": "v1", "k2": "v22"},
})
|
| promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k1": "v1", "k2": "v2"},
})
promauto.NewCounter(prometheus.CounterOpts{
Name: "name",
ConstLabels: prometheus.Labels{"k1": "v11", "k2": "v22"},
})
