Caching Server No Caching Services???

Some detail information is available via command line without

any special privileges.

On your "Content Sharing" server, open a Terminal window

and enter the command and hit return:

AssetCacheManagerUtil status

It gives details such as follows:

Built-in caching server status: {

Activated = 1;

Active = 1;

CacheDetails = {

"Mac Software" = 10595586693;

iCloud = 92224101;

"iOS Software" = 4192563429;

};

CacheFree = 135119625777;

CacheLimit = 150000000000;

CacheStatus = OK;

CacheUsed = 14880374223;

Parents = (

);

Peers = (

);

PersonalCacheFree = 149907775899;

PersonalCacheLimit = 150000000000;

PersonalCacheUsed = 92224101;

Port = 50190;

PrivateAddresses = (

"192.xxx.x.x"

);

PublicAddress = "xxx.xx.xx.xx";

RegistrationStatus = 1;

RestrictedMedia = 0;

ServerGUID = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";

StartupStatus = OK;

TotalBytesDropped = 0;

TotalBytesImported = 0;

TotalBytesReturnedToChildren = 0;

TotalBytesReturnedToClients = 0;

TotalBytesReturnedToPeers = 0;

TotalBytesStoredFromOrigin = 0;

TotalBytesStoredFromParents = 0;

TotalBytesStoredFromPeers = 0;

}

I did the following test:

Downloaded 3 iOS app updates via iTune 12.6.2 (can't do it with 12.7)

on ClientA. "iOS Software" increased by 375Meg as did CacheUsed.

But the TotalBytesStoredFromOrigin was 193Meg and TotalBytesReturnedToClients

was the same. Now, why the increase in stored is double??

I then went to ClientB which showed the same app updates in its

iTunes and proceded to update. The total cache size nor the iOS Software

component changed. But, TotalBytesStoredFromOrigin jumped to 375 Meg

and TotalBytesReturnedToClients was 569 Meg???

So, it is not clear if anything was actually served from cache on this

server or not? Seems to me that those last numbers indicate that

the latest and greatest "Content Caching" doesn't work!

Also tried the same thing with an app downloaded from the MacApp Store,

and it didn't show any changes like its totally ignored the request!!

This great "Content Caching" is seriously hosed!!!!!!!!!!!!!

It moved out of Server and into macOS High Sierra. Open System Preferences > Sharing > Content Caching. Press your keyboard's option key to turn Options... into Advanced Options... if those interest you.

Thanks! I guess I need to wait to see how much control there is

over the cache size until High Sierra is released. I would hope

there is some control.

macOS High Sierra's content cache supports iOS devices, Apple TVs, and Macs, just like macOS Server's caching server does.

I read the Apple document on the High Sierra Content Caching and

it seems to only focus on iDevices. Does that mean there will no longer

be any caching of macOS upgrades/updates and Mac app downloads/updates

which is currently handled with Server?

It was handy and quick to download to one Mac on the network and have it

available locally for all the other Macs on the network. Especially the big ones

like macOS upgrades and Xcode updates which tend to be multi gig. This was one

of the driving forces in selecting Apple's Server app versus other solutions.

Does anyone know if there is still an ability to see the "Caching Statistics" to see how well of a job it is doing? I used to look at that daily to see how much data came from Apple vs the internal caching server.
