---------------------------------------
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.
