---------------------------------
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:
https://stackoverflow.com/questions/29674488/whitespace-in-statsd-metric-name
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.
