----------------------------------------
Summary: Add per-stage RequestHandler metrics
Key: SOLR-11778
URL: https://issues.apache.org/jira/browse/SOLR-11778
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: metrics
Reporter: Andrzej Bialecki
Assignee: Andrzej Bialecki
Currently {{RequestHandlerBase}} defines several metrics for keeping track of
general-purpose requests. These metrics are also used in {{SearchHandler}}.
However, query processing in SolrCloud consists of several (varying) stages,
and each of these stages may result in additional shard requests. These details
are not captured by the metrics, because they treat all requests the same way.
In some applications it's important to know how many requests are user
requests, and how many of them are generated internally by SolrCloud - for
example, when diagnosing uneven distribution of requests across shards, or when
autoscaling framework wants to detect "hot replicas". If we split the metrics
at least into distributed vs. non-distributed requests then the numbers become
more meaningful and representative of the global load vs. local load.
