             Summary: Opencensus metrics do not work well with Prometheus
                 Key: IGNITE-17398
                 URL: https://issues.apache.org/jira/browse/IGNITE-17398
             Project: Ignite
          Issue Type: Improvement
            Reporter: Sergey Kadaner


The metrics created by the new metrics system are very inconvenient to use with Prometheus since it does not use tags.

For example, Spring metric generated for the same cache looks like the following in Prometheus and is very convenient to use:  

 
{noformat}
cache_gets_total{cache="MY_CACHE_NAME",name="MY_CACHE_NAME",result="hit",} 1387.0{noformat}
 

The native Ignite metric looks like the following: 

 
{noformat}
cache_MY_CACHE_NAME_CacheHits 1387.0{noformat}

The Spring reported statistics can be easily filtered by cache name and other attributes, while the build-in Ignite metrics do not provide an easy way to access cache names. The only option seems to be parsing the "cache_MY_CACHE_NAME_CacheHits" strings which AFAIK is not supported by Grafana.
