Hi Chesnay, If removing the metrics is not possible from Flink GUI, while the job is running. Then kindly tell me how to update a metric counter.
Explaination: Suppose I created a metric Counter with key "chesnay" and incremented the counter to 20, by code mentioned below. getRuntimeContext().getMetricGroup().counter("chesnay").inc(20); /Note: I am not assigning this counter to any local/member variable as I do not want to keep state in my job./ Now, after some time, If I want to update the value of "chesnay" metric counter to 60 and I am not aware about the old state (which is 20). So, If I do getRuntimeContext().getMetricGroup().counter("chesnay").inc(60); Event then Flink GUI shows value 20 for "chesnay" metric Group. and gives a WARN log something like this, "same name can be used, and behavior is undefined". Now, how to update the "chesnay" metric Group if I do not want to keep the state in my Job??? Thats why, I though of creating user scoped metric group and thought of closing that group to remove the metric counters and create new metrics every time, when I want to update it. Hope you understood my problem. -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
