This > means that you're not going to be able to use tags to differentiate the > metric values coming from different environments. > Currently, every metric reported by this task gets the same set of tags > applied: > {code:java} > connection-destination-id > connection-destination-name > connection-group-id > connection-id > connection-name > connection-source-id > connection-source-name > dataflow_id > env > port-group-id > port-id > port-name{code} > This list is defined here: > [https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-datadog-bundle/nifi-datadog-reporting-task/src/main/java/org/apache/nifi/reporting/datadog/metrics/MetricsService.java#L111-L126] > I've attached a screenshot from Datadog demonstrating a JVM metric with all > of these tags applied. > Each of these tags should include a value, i.e. "env:dev" instead of just > "env". > Other observations: > * it doesn't make sense to attach the _connection-_ and _port-_ tags to JVM > metrics > * I'm not sure I see any value in the _dataflow_id_ tag > I was hoping for a quick fix when I noticed the environment tagging wasn't > working, but after reviewing the code I think a not insignificant refactoring > will be required. I'll try to tackle this if/when time allows. > See here for more context on Datadog tagging: > [https://docs.datadoghq.com/tagging] > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
