[jira] [Created] (FLINK-6910) Metrics value for lastCheckpointExternalPath is not valid

Chris Dail created FLINK-6910:
---------------------------------

             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: bce343c5-393a-4f70-bd0c-f7578443c9a4-0005.flink__9ef0b9a8-533a-4b5e-8667-1967e9cae849.a473fcfe-0907-4084-8eff-f5f0c3ea1844.flink.jm.TurbineHeatProcessor_examples_turbineHeatTest.lastCheckpointExternalPath:n/a|g
{noformat}

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