             Summary: StatsD Metrics name should escape spaces 
                 Key: FLINK-6911
                 URL: https://issues.apache.org/jira/browse/FLINK-6911
             Project: Flink
          Issue Type: Improvement
          Components: Metrics
    Affects Versions: 1.3.0
         Environment: StatsD Metrics with Telegraf server
            Reporter: Chris Dail


The StatsDReporter does not escape spaces in the metric name. It is generally accepted that spaces in the metric name are a bad idea:

Specifically, I am integrating with Telegraf. It actually splits the name on spaces and treats these as (name, value, timestamp). It ignores everything except the name.
https://github.com/influxdata/telegraf/blob/master/plugins/parsers/graphite/parser.go#L225

Initially I found this issue when I had a space in the job name. Flink encodes the job name into the metrics as is. So when I put these into telegraf, all of the job level metrics ended up with the same bucket in telegraf.

Flink also uses things like "Sink- <name>" and "Source- <name>" to encode source/sink. These also do not work with telegraf. I end up with metrics that look like this inside telegraf:

{noformat}
taskmanager_5e453417d87c755da6311b1940cc602f_TurbineHeatProcessor_examples_turbineHeatTest_Sink-
{noformat}

The actual name is truncated after the space.
