> Key: SOLR-12734
> URL: https://issues.apache.org/jira/browse/SOLR-12734
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Varun Thacker
> Assignee: Varun Thacker
> Priority: Major
>
> I just had a user who confused the metrics we show for the zookeeper admin
> handler and think this was actual ZooKeeper metrics
>
> For example metrics like these
> {code:java}
> "ADMIN./admin/zookeeper.clientErrors":{
> "count":0,
> "meanRate":0.0,
> "1minRate":0.0,
> "5minRate":0.0,
> "15minRate":0.0},
> "ADMIN./admin/zookeeper.errors":{
> "count":0,
> "meanRate":0.0,
> "1minRate":0.0,
> "5minRate":0.0,
> "15minRate":0.0},
> "ADMIN./admin/zookeeper.handlerStart":1536093060895,
> "ADMIN./admin/zookeeper.requestTimes":{
> "count":0,
> "meanRate":0.0,
> "1minRate":0.0,
> "5minRate":0.0,
> "15minRate":0.0,
> "min_ms":0.0,
> "max_ms":0.0,
> "mean_ms":0.0,
> "median_ms":0.0,
> "stddev_ms":0.0,
> "p75_ms":0.0,
> "p95_ms":0.0,
> "p99_ms":0.0,
> "p999_ms":0.0},{code}
> Thinking about this these metrics don't seem useful at all to me and would
> just confuse users
>
> My proposal is to remove the metrics we display for the following admin
> handlers as they don't add any value and reduces the verbosity of the
> response
> {code:java}
> /admin/info
> /admin/configs
> /admin/zookeeper
> /admin/zookeeper/status
> /admin/info/system
> /admin/metrics/history
> /admin/autoscaling
> /admin/autoscaling/history
> /admin/autoscaling/diagnostics
> /admin/autoscaling/suggestions{code}
> Admin handlers that we should still keep metrics . These might be helpful to
> some user who wants to see how many requests fail, how many times is my
> monitoring tool calling the metrics API etc
> {code:java}
> /admin/health
> /admin/authentication
> /admin/authorization
> /admin/metrics
> {code}
