Subject Re: Flink Metrics - InfluxDB + Grafana | Help with query influxDB query for Grafana to plot 'numRecordsIn' & 'numRecordsOut' for each operator/operation
Date Tue, 01 Nov 2016 23:30:26 GMT
Hi Jamie,

Thank you so much for your response. 

The below query:

SELECT derivative(sum("count"), 1s) FROM "numRecordsIn" WHERE "task_name" =
'Sink: Unnamed' AND $timeFilter GROUP BY time(1s)

behaves the same as with the use of the templating variable in the 'All'
case i.e. shows a plots of junk 'negative values'

It shows accurate results/plot when an additional where clause for
"subtask_index" is applied to the query.

But without the "subtask_index" where clause (which means for all the
subtask_indexes) it shows some junk/incorrect values on the graph (both
highly positive & highly negative values in orders of millions)
