Ruby Andrews created FLINK-10557:
------------------------------------
Summary: Checkpoint size metric incorrectly reports the same value
until restart
Key: FLINK-10557
URL: https://issues.apache.org/jira/browse/FLINK-10557
Project: Flink
Issue Type: Bug
Components: Metrics
Affects Versions: 1.4.0
Reporter: Ruby Andrews
We have seen the following several times, but have not found the root cause.
The checkpoint size metric will sometimes report the same value over and over,
even though the checkpoint size is changing. The last time we saw this, it
happened for 4 days, until we re-started the Flink cluster. In that time
period, the application flushes all data each day so we would expect to see the
checkpoint size grow until UTC midnights, then go to about 0 and begin growing
again.
It appears that the metrics continue to be gathered, because we see them in our
data repository where we are reporting them. However, the size does not change.
Is there more information we can gather to root cause this if it happens again?
