Eugene Klimov created ZOOKEEPER-3929:
----------------------------------------
Summary: prometheus metrics with type "summary" always show
quantiles as NaN
Key: ZOOKEEPER-3929
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3929
Project: ZooKeeper
Issue Type: Bug
Components: metric system
Affects Versions: 3.6.1, 3.6.0
Reporter: Eugene Klimov
I run the following command on fresh installed Zookeeper:
{code:java}
wget -O- -q http://127.0.0.1:7000/metrics | grep -i readlatency{code}
and got the following results:
{code:java}
# HELP readlatency readlatency
# TYPE readlatency summary
readlatency{quantile="0.5",} NaN
readlatency{quantile="0.9",} NaN
readlatency{quantile="0.99",} NaN
readlatency_count 220.0
readlatency_sum 330.0
{code}
look like quantiles don't calculate properly
