-----------------------------------
Summary: Improve Tracing operation names and tags
Key: SOLR-15392
URL: https://issues.apache.org/jira/browse/SOLR-15392
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: David Smiley
Assignee: David Smiley
The distributed tracing span "operation name" should be a low cardinality
value, ideally not including host names or data set names or similar. Ideally
it starts with a verb then has something else about what the verb is applied
to. Examples:
* {{get:/select}}
* {{post:/update}}
* {{list:/admin/collections}}
* {{create:/admin/cores}}
The following [span tags|https://opentracing.io/specification/conventions/]
could be populated:
* {{db.type}} : "solr"
* {{db.user}} : current authenticated user
* {{db.instance}} : collection or core (whichever the request is addressed to)
