-----------------------------------------

[~ab] this is that 1-line change we briefly chatted about in Vegas.  It would 
be great if you could this in in the next Solr 7.x minor release. Thanks.

> Before Solr 7.*, cache maxSize and autowarm settings were exposed in JMX 
> along with cache metrics. There was a textual attribute "description" which 
> could be parsed to extract maxSize and autowarm settings. This was very 
> useful for various monitoring tools since maxSize and autowarm could then be 
> displayed on monitoring charts (one could for example compare current size of 
> some cache to its maxSize without digging through configs to find this 
> setting).
> Ideally maxSize and autowarm count/% would be exposed as two separate 
> attributes, but having a single description field (which can be parsed) would 
> also be better than nothing.
