Hai Zhou UTC+8 commented on FLINK-6910:
---------------------------------------

the lastCheckpointExternalPath metric type is Gauge<String>. 
so this is not a issue.

>          Issue Type: Bug
>          Components: Metrics
>    Affects Versions: 1.3.0

> The value for the lastCheckpointExternalPath metric seems to be a string (I'm seeing
a value of 'n/a'). The metric type is a gauge which is required to be a float.
> Telegraf gives an error on this:
> {noformat}

> {noformat}
> This is pretty minor since telegraf will ignore this an continue on. Other StatsD backends
may behave differently.
