auto-deprioritized-major)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Minor but is unassigned and neither itself nor its Sub-Tasks have been updated
for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is
still Minor, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Avoid InfluxdbReporter to report unnecessary tags
> -------------------------------------------------
>
> Key: FLINK-13418
> URL: https://issues.apache.org/jira/browse/FLINK-13418
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Metrics
> Reporter: Yun Tang
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor
>
> Currently, when building measurement info within {{InfluxdbReporter}}, it
> would involve all variables as tags (please see code
> [here|https://github.com/apache/flink/blob/d57741cef9d4773cc487418baa961254d0d47524/flink-metrics/flink-metrics-influxdb/src/main/java/org/apache/flink/metrics/influxdb/MeasurementInfoProvider.java#L54]).
> However, user could adjust their own scope format to abort unnecessary
> scope, while {{InfluxdbReporter}} could report all the scopes as tags to
> InfluxDB.
> This is due to current {{MetricGroup}} lacks of any method to get necessary
> scopes but only {{#getScopeComponents()}} or {{#getAllVariables()}}. In other
> words, InfluxDB need tag-key and tag-value to compose as its tags while we
> could only get all variables (without any filter acording to scope format) or
> only scopeComponents (could be treated as tag-value). I think that's why
> previous implementation have to report all tags.
> From our experience on InfluxDB, as the size of tags contribute to the
> overall series in InfluxDB, it would never be a good idea to contain too many
> tags, not to mention the [default value of series per
> database|https://docs.influxdata.com/influxdb/v1.7/troubleshooting/errors/#error-max-series-per-database-exceeded]
> is only one million.
