---------------------------------
Summary: Metrics value for lastCheckpointExternalPath is not valid
Key: FLINK-6910
URL: https://issues.apache.org/jira/browse/FLINK-6910
Project: Flink
Issue Type: Bug
Components: Metrics
Affects Versions: 1.3.0
Environment: Testing against a Telegraf StatsD server.
Reporter: Chris Dail
Priority: Minor
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}
2017-06-12T15:02:21Z E! Error: parsing value to float64:

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