Chris M. Hostetter commented on SOLR-16773:
-------------------------------------------
>From reading the diff, it looks like it should work – but frankly i feel like
>the "real" bug is the fact that we're using a regex at all.
The current logic loops over the {{cores}} from {{CLUSTERSTATUS}} and applying
a regex to {{core['core']}} to munge it into a {{coreMetricName}} key we can
lookup in {{m.metrics}} to find {{coreMetric = m.metrics[coreMetricName];}}
But all of those {{coreMetric}} entries in {{m.metrics}} have a
{{"CORE.coreName"}} property.
So why don't we instead do a single loop over {{m.metrics}} to build a new Map
of the entries, keyed off of {{{}coreName{}}}, and do our lookups against that
- no regex needed.

> Consider the following cluster w/three collections (including the

> {noformat}
> ./solr/packaging/build/dev/bin/solr -e cloud -noprompt
> curl -sS
> 'http://localhost:8983/solr/admin/collections?action=CREATE&name=named_shards&router.name=compositeId&numShards=2&shards=shardX,shardY'

> If you look at the Cloud>Nodes screen for this cluster, the "Disk Usage" (and
> other metrics) for the cores from the {{implicit_named_shards}} collection
> wound show up. (see screenshot)
>
> The problem is that {{cloud.js}} expects core names to follow a very specific
> format, but implicit router names it's cores directly after the shard names
> specified.
