Core services like Google Cloud Print and Mail Print must be enabled to be on the list.
-
Web Print and Internet Print services are a fixed part of the list.

Plug-in services like Mollie and Blockchain.info Payment Gateways are part of the list if they are enabled in their property file.
With Dashboard Editor Privileges, you can turn a service On or Off by flipping the status switch. With Reader Privileges service switching is disabled.
When the SavaPage server restarts enabled core
services are turned On by default. The initial
state of enabled plug-in services is governed by the
online setting in their property file. The on/off state of
Internet Print translates to the enabled/disabled state of the
reserved /internet
Queue.
The News section shows the currently installed versus the latest published SavaPage version. A push on the button brings you to the Internet page [11].
The Pagometers[12] counting the pages printed-out with Proxy Printers, printed-in from SavaPage Queues, and exported as PDF are displayed in a Pie-Chart. Pagometers are explained at Section 4.10.14.10, “Pagometers”.
A Line-Graph shows the day pagometers for the three sources over the last 30 days.
The Environmental Impact for the Proxy Printer pagometer are displayed in a separate section. The metrics and units used are discussed at Section 14.2, “Environmental Impact”.
The Environmental Impact section can be hidden with configuration property in table below.

A Financial Summary of User Accounts and Bitcoin Wallet is displayed in a separate section.
The User Accounts total and statistics like
Min, Max and
Avg are shown as Debit or
Credit amount over Count number of
accounts.
When a Bitcoin Payment Gateway is enabled the Bitcoin Wallet balance (Debit) is shown in the system currency and BTC. The Total number of Bitcoin Addresses in the wallet are split into addresses that received Payments, and Open addresses waiting for payments. Note that other addresses, not created by our Bitcoin Payment Plug-in, may be part of the wallet (in our example there is one such address).
The Bitcoin Wallet hyperlink opens the Web Wallet in a new browser tab.
The Accounts summary is updated as the dashboard is (auto) refreshed. However, the Bitcoin Wallet summary is cached by SavaPage and lazy refreshed after a configurable time period (defaulting to 3600 seconds).[13] The date/time of the last refresh is shown in the Date column. Press the button to force a refresh of the cache.
Relevant system events are real-time displayed in this section. A
maximum of 20 event messages remain in view, with the most recent one at the
top.
System events are persisted in the rotating log file:
/opt/savapage/server/logs/adminpublisher.log
This file has a tab separated value (TSV) format for easy import and
manipulation into spreadsheet programs. See
/opt/savapage/server/lib/log4j.properties.template
for more information.
[11] The latest published SavaPage version number is cached on the server and retrieved from the Internet every 12 hours.
[12] In analogy with the term Odometer, the term Pagometer is introduced as an instrument to count the number of processed pages.
[13] Edit the webapp.admin.bitcoin.wallet.cache-expiry-secs
configuration property with the Configuration Editor to set the number of seconds after
which the cached Bitcoin Wallet summary is refreshed.
