Optional features

The following are optional features:

Configure Caching service logging

By default, the Caching service will not log the model and iOS/OS X version. In order to get true results from this script, run the following command (as root):

sudo cacher.py --configureserver

If successful, you will see the following output:

Caching Server settings are now: caching:LogClientIdentity = yes

Target date

By default, Cacher will use look for logs from the previous date. To target logs from a custom date, use the --targetdate option.

cacher.py --targetdate "2016-11-28"

Log path

By default, Cacher will use look for logs from in /Library/Server/Caching/Logs. To target logs in a custom path, use the --logpath option.

cacher.py --logpath "/path/to/logs"

DeviceIDs

By default, Cacher will use the "Friendly Names" for iOS devices. To use the model Device ID, use the --deviceids option.

cacher.py --deviceids

Device IDs Example:

A total of 3513 iOS downloads were requested from the Caching Server yesterday consisting of:
 A total of 4 Apple TV downloads
 A total of 417 iPad downloads
 A total of 3075 iPhone downloads
 A total of 17 iPod downloads

No Standard output

By default, Cacher will print the results to standard out. To skip this use the --nostdout option.

cacher.py --nostdout

Server alert

By default, Cacher will no longer send a server alert. To send a server alert, use the --serveralert option.

Please note that this option requires root/sudo level permissions.

sudo cacher.py --serveralert

If you attempt to use this option without elevated permissions, Cacher will write the following note to standard out.

Did not send serverAlert - requires root

Slack alert

By default, Cacher will not send a server alert. To send a server alert, use the --slackalert option.

The slack alert requires two other options to be passed:

  • --slackchannel

Username or Channel

You can pass both an username or channel via the --slackchannel option: Examples:

  • @erik

Slack webhook

A slack webhook must be created. To create a webhook, please go here

cacher.py --slackalert \
