> Key: SOLR-16639
> URL: https://issues.apache.org/jira/browse/SOLR-16639
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: contrib - prometheus-exporter
> Affects Versions: main (10.0)
> Reporter: Naoto Minami
> Priority: Major
> Labels: SolrCloud
>
> jq expr `select(.key | endswith(".completed"))` matches "*.tasks.completed"
> too. But the format of "*.tasks.completed" metrics is like bellow:
> "QUERY.httpShardHandler.threadPool.httpShardExecutor.tasks.completed":16,
> [https://github.com/apache/solr/blob/bf490f16b5e1acbbd4b01ec3aa1e5b035096716a/solr/prometheus-exporter/conf/solr-exporter-config.xml#L541]
> So, $object.value.count jq expr occurs jq parse error. I will fix this
> problem to add `select(.value | type=="object")` filter to jq expr.
>
> Note:
> I uses solr-exporter with -z parameter (as SolrCloud mode)
