Caching module

Get status of macOS' caching service.

###Now supports macOS High Sierra! Can be installed on all 10.13+ clients.

##Config Options

Because of the drastic change in how the caching data is stored between 10.8-10.12 and 10.13+, the listing was completely rewritten. The older, itemized listing is still available under the "Caching Itemized" listing. To hide the Itemized listing, set the config option "caching_show_itemized" to FALSE.

Configuration

Legacy Caching Listing

Starting with 10.13, Apple changed the caching server. In MunkiReport, you can hide the legacy caching server listing that shows an itemized listing for all caching server transactions for caching servers running 10.8-10.12. To hide the "Caching (Legacy)" listing, set this to FALSE.

CACHING_SHOW_ITEMIZED=FALSE
