> Key: FLINK-16397
> URL: https://issues.apache.org/jira/browse/FLINK-16397
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Metrics
> Affects Versions: 1.9.2, 1.10.0
> Reporter: BlaBlabla
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor
>
> I'm using flink GraphiteReporter to monitor metrics. But I found that the
> GraphiteReporter will convert double / float type metrics to the format :
> "%2.2f", only keep two fractions. For instance, Status.JVM.CPU.Load metric
> is loss of precision, like 0.00, 0.01 .
> it is bad :(
> For more detail, see the double format function in dropwizard metrics
> project::
> [https://github.com/dropwizard/metrics/blob/4.1-development/metrics-graphite/src/main/java/com/codahale/metrics/graphite/GraphiteReporter.java#L401]
> {code:java}
> protected String format(double v) {
> // the Carbon plaintext format is pretty underspecified, but it seems
> like it just wants
> // US-formatted digits
> return String.format(Locale.US, "%2.2f", v);
> {code}
